Roll containers are often purchased for supermarket distribution, warehouse circulation, retail replenishment, e-commerce fulfillment and industrial material handling. A standard model may work for general cargo, but large retail chains, logistics companies and distributors usually have more specific requirements: non-standard dimensions, different load capacities, special wheels, folding structures, doors, colors, logos, packaging or container-loading requirements.

SUVA's roll container range supports OEM and customized production. Its published information covers custom dimensions, structural requirements, color, logo and packaging, while its factory handles metal fabrication, welding, forming, assembly, quality inspection and packaging in-house. SUVA also states that its engineers can assist with product design and proofing for customized projects.

For buyers, the key is not simply asking a factory to "make a custom roll cage." A good OEM specification should define the working dimensions, load, frame structure, caster system, access design, surface treatment, folding method, branding and shipping configuration before production begins.

1. What Can Be Customized on a Roll Container?

A roll container can normally be customized in several areas:

SUVA's published specifications include dimensions from 850 × 670 × 1,750 mm to 1,100 × 800 × 1,700 mm, load capacities from 200–1,500 kg, caster options of Φ100–Φ120 mm, and different surface treatments. The site also lists color, logo and packaging as customizable items.

2. Start with the Application

Before discussing dimensions, tell the manufacturer where the roll container will be used.

Supermarket replenishment

Important factors:

• Easy pushing
• Fast loading
• Good visibility
• Narrow aisle compatibility
• Durable casters
• Easy store unloading

Distribution center

Focus on:

• Load capacity
• Wheel durability
• Nesting
• Stackability
• Fast handling

E-commerce warehouse

Consider:

• Picking efficiency
• Parcel containment
• Foldability
• Door access
• Return logistics

Industrial plant

Usually requires:

• Higher load capacity
• Reinforced base
• Larger casters
• Stronger frame
• Long service life

Hotel and laundry logistics

Consider:

• Easy cleaning
• Smooth surfaces
• Corrosion resistance
• Covers or enclosed sides

SUVA lists warehousing, logistics, retail, e-commerce, manufacturing, hotel and laundry operations among the applications for its roll container range.

3. Custom Roll Container Dimensions

Dimensions are usually the first item discussed in an OEM project.

Specify:

Length × Width × Height

For example:

• 850 × 650 × 1,700 mm
• But this is not enough.

Also define:

• Overall height
• Usable internal height
• Internal width
• Internal depth
• Base height
• Wheel height
• Handle height
• Door opening
• Mesh panel dimensions

SUVA's roll container cage page gives a general dimensional range of 850 × 670 × 1,750 mm to 1,100 × 800 × 1,700 mm, while its broader product information states that the height can range from approximately 1.5–2 m and width/depth from 0.8–1.2 m for certain roll cage configurations.

For an OEM project, use a drawing rather than relying on a product-page dimension.

4. Custom Load Capacity

The load requirement should be defined before the frame is designed.

Typical questions include:

• What is the maximum cargo weight?
• Is the load evenly distributed?
• Are heavy products concentrated at the bottom?
• Will the cage be pushed manually?
• Will forklifts or other equipment handle it?
• Will it be stacked?
• Will it move over uneven floors?

SUVA publishes roll container capacities ranging from 200 kg to 1,500 kg across its listed configurations, while one roll cage specification describes 500–1,000 kg capacity with customization available.

A 1,000 kg requirement should not simply be handled by adding thicker wire. The manufacturer may need to modify:

• Base structure
• Vertical supports
• Horizontal rails
• Weld points
• Caster brackets
• Wheel specifications

5. Frame Tube Customization

The frame determines much of the cage's strength.

OEM specifications can include:

• Tube diameter
• Tube wall thickness
• Tube shape
• Horizontal reinforcement
• Vertical reinforcement
• Base frame
• Corner structure

For heavy-duty applications, ask the manufacturer to provide:

Material specification + tube specification + load rating

rather than simply asking for a "stronger frame."

SUVA states that its roll container cages use high-strength steel and that its factory carries out wire drawing, cutting, mesh welding, forming, assembly and inspection processes in-house.

6. Mesh Panel Customization

The mesh affects both cargo containment and product visibility.

Specify:

• Wire diameter
• Mesh opening
• Panel height
• Panel width
• Number of horizontal supports
• Welding points
• Edge treatment

Smaller mesh opening

Better for:

• Small cartons
• Loose products
• Parcel handling

Larger mesh opening

Better for:

• Large cartons
• Lower material consumption
• Better visibility

For retail distribution, the correct mesh size should be based on the smallest product that must remain inside the cage.

7. Two-Sided, Three-Sided or Four-Sided Custom Design

SUVA offers different roll cage configurations.

Two-Sided

Open front and rear.

Best for:

• Fast loading
• Replenishment
• Short-distance handling

Three-Sided

Adds a rear panel.

Best for:

• Distribution
• Warehouse storage
• Retail replenishment

Four-Sided

Provides a more enclosed structure.

Best for:

• Security
• Parcel handling
• Higher-value products
• Controlled logistics

SUVA specifically lists 2-sided, 3-sided, 4-sided, nestable and foldable roll cage configurations.

8. Custom Door Design

Door design should match the loading method.

Possible options include:

• No door
• Half door
• Full door
• Single door
• Double door
• Folding door
• Lockable door

SUVA's roll cage specifications include lockable and foldable doors.

For supermarket distribution, a half-door may make unloading faster. For higher-security applications, a lockable full door is more suitable.

9. Custom Folding Mechanism

Foldability becomes particularly valuable when empty cages need to return to a distribution center.

SUVA describes foldable designs as space-saving solutions for warehouse storage and return logistics.

A custom folding specification should define:

• Which panels fold
• Folding direction
• Folded dimensions
• Hinge location
• Locking mechanism
• Maximum folded stack
• Number of cages that can be nested

Do not specify only "foldable." The manufacturer needs to know how the cage should behave when folded and transported.

10. Nestable Roll Container Customization

Nestable cages can reduce empty-storage volume and return-transport costs.

The design normally depends on:

• Frame angle
• Base geometry
• Wheel position
• Side-panel position
• Nesting clearance

The OEM should provide:

Working size + nested size + nesting quantity

For example:

• Working height: 1,700 mm
• Nested pitch: 250 mm
• Maximum nested quantity: 10 units

These figures are much more useful for logistics planning than simply stating "nestable."

11. Custom Caster Selection

The caster system should be selected according to:

• Total load
• Floor condition
• Wheel diameter
• Pushing frequency
• Turning radius
• Noise requirement
• Brake requirement
• Temperature
• Chemical exposure

SUVA lists Φ100–Φ120 mm caster options on its roll cage specifications. Its product descriptions also identify four casters, including two swivel wheels, for warehouse movement.

Common configuration

2 fixed wheels

2 swivel wheels

Optional requirements can include:

• Brakes
• Silent wheels
• Heavy-duty wheels
• Different wheel materials

12. Custom Wheel Material

The floor often determines the wheel material.

Rubber

Suitable where:

• Noise matters
• Floors are relatively smooth
• Manual pushing is frequent

PU

Useful where:

• Load is higher
• Rolling resistance matters
• Floor protection is important

Cast iron

More suitable for certain industrial applications where durability is prioritized over floor protection and noise.

The wheel should be selected together with the cage load. A heavy cage fitted with an undersized wheel will create problems even when the steel structure itself is strong.

13. Custom Base Design

The base carries the cargo and transfers load to the wheels.

Possible designs include:

• Wire mesh base
• Steel tube base
• Sheet steel base
• Reinforced base
• Removable base

For heavy products, ask the manufacturer to specify:

• Base material
• Tube size
• Cross-member arrangement
• Maximum distributed load
• Point-load capacity

A cage designed for cartons may not be suitable for machinery components or dense metal parts without modifying the base.

14. Custom Shelves

Shelves can turn a simple roll cage into a multi-level picking trolley.

SUVA's roll container range supports customized configurations and accessories, depending on the model.

Specify:

• Number of shelves
• Shelf height
• Shelf depth
• Fixed/removable
• Folding/removable
• Shelf load
• Edge height

For e-commerce picking, adjustable shelves can make better use of vertical space.

15. Custom Covers

Covers are useful when goods need protection from:

• Dust
• Rain
• Direct sunlight
• Unwanted access
• Warehouse contamination
• The cover specification should include:
• Material
• Thickness
• Color
• Logo
• Closure method
• Velcro/zipper/strap
• Waterproof requirement

SUVA lists protective covers among available customization options for its roll container products.

16. Surface Treatment Customization

SUVA lists several surface-treatment options:

• Plastic powder coating
• Chrome plating
• Galvanizing
• Zinc oxide

Choose the finish according to the working environment.

Powder coating

Suitable for:

• Retail
• Warehouses
• General logistics

Galvanizing

Useful where greater corrosion resistance is required.

Chrome plating

Used where appearance and surface characteristics are important.

For coastal, humid or frequently washed environments, corrosion protection deserves more attention than simply selecting a color.

17. Custom Color

Color should be specified with an internationally recognized color code.

Instead of:

"Make it blue."

Use:

RAL 5015

or another agreed color standard.

SUVA provides customized colors and brand-specific appearance options.

The OEM specification should identify:

• Frame color
• Mesh color
• Door color
• Handle color
• Plastic component color
• Logo color

For chain retailers, use an approved physical sample before mass production.

18. Custom Logo and Branding

Branding can be added through:

Metal plate

Printed label

Laser engraving

Logo plate

Customized cover

Painted logo

The OEM drawing should specify:

Logo position + logo size + logo method + artwork format

SUVA states that it provides private branding and logo customization as part of its OEM/ODM services.

19. Custom Locking System

For four-sided cages or security applications, the locking system should be specified separately.

Possible options:

• Simple latch
• Sliding latch
• Padlock provision
• Built-in lock
• Lockable handle

Consider:

• Ease of operation
• Resistance to accidental opening
• Corrosion resistance
• Replacement availability

A supermarket replenishment cage may need a quick latch, while a pharmaceutical or electronics logistics cage may require more controlled access.

20. Custom Handle Design

Handle height affects operator comfort.

For OEM projects, define:

• Handle height
• Tube diameter
• Grip material
• Grip shape
• Welded or bolted connection
• The handle should also be checked against:
• Door movement
• Nesting
• Container loading
• Warehouse aisle width

SUVA includes handle inspection as part of its roll cage maintenance guidance, which reflects the amount of repeated force this component receives during normal use.

21. Custom Dimensions for Narrow Aisles

For supermarket backrooms and warehouses, aisle width can determine cage dimensions.

Before finalizing the width, measure:

• Aisle width
• Door width
• Elevator width
• Loading bay width
• Turning radius
• Storage location

A cage that fits a standard warehouse aisle may not fit a supermarket backroom.

For a chain-wide project, check the smallest operating location, not just the largest distribution center.

22. Custom Roll Container for Container Shipping

Shipping should be considered during design.

A larger cage may work better operationally but reduce the number of units per 40HQ.

SUVA's published loading examples show major differences between assembled and knocked-down configurations. For one 760 × 819 × 1,817 mm model, its listed 40HQ loading is 90 assembled units versus 350 knocked-down units.

Therefore, OEM buyers should request:

• Assembled loading quantity
• Knocked-down loading quantity
• Nested quantity
• Folded dimensions
• 40GP quantity
• 40HQ quantity
• before approving the final design.

23. Custom Packaging

Packaging can also carry the customer's brand.

Possible requirements:

• Individual protective packaging
• Bulk packing
• Plastic film
• Foam protection
• Carton for accessories
• Custom labels
• Barcode
• Shipping marks

SUVA's FAQ states that its OEM/ODM service includes customized packaging.

For export projects, the packaging drawing should be approved before mass production.

24. OEM Prototype and Sample Approval

For a new design, do not move directly from a rough sketch to 1,000 units.

A safer process is:

Requirement

↓

Technical drawing

↓

Quotation

↓

Prototype

↓

Sample inspection

↓

• Door position
• Handle

Side View

• Depth
• Wheel location
• Base height

Top View

• Internal dimensions
• Frame structure
• Wheel position

Detail Drawings

• Lock
• Handle
• Mesh
• Base

For OEM production, drawings should also identify:

• Material
• Tube dimensions
• Wire diameter
• Mesh opening
• Welding requirements
• Surface treatment
• Tolerance

27. OEM Material Specification

Do not leave the material description as simply:

"Steel."

Specify the required material standard where appropriate.

For example:

• Steel grade
• Wire diameter
• Tube specification
• Sheet thickness
• Mechanical requirements

SUVA states that it uses high-quality steel for its roll containers and identifies Shagang and Baosteel among its steel sources on its product page.

For a long-term OEM program, consistent material sourcing is important because changes in steel properties can affect welding, forming and final product strength.

28. Welding Requirements

A custom roll container may contain dozens or hundreds of welded joints.

The OEM specification should define:

• Welding method
• Weld location
• Weld appearance
• Weld strength requirement
• Critical structural joints
• Acceptable defects

SUVA states that its factory has automated welding and forming equipment and carries out mesh panel welding, assembly and quality inspection as part of its production process.

29. Custom Quality Requirements

A good OEM contract should include measurable quality requirements.

Dimensions

Specify tolerance.

Welds

Specify acceptable appearance and structural requirements.

Wheels

Specify:

• Diameter
• Load
• Rotation
• Mounting

Coating

Specify:

• Color
• Coating type
• Surface quality
• Corrosion requirements

Function

Specify:

• Folding cycles
• Door operation
• Lock operation
• Wheel movement

This gives both sides a clear inspection standard.

30. SUVA Manufacturing Process for OEM Projects

SUVA describes an integrated production process covering:

Wire Drawing & Cutting

↓

Mesh Panel Welding

↓

Forming / Tube Processing

↓

Plating / Surface Treatment

↓

Assembly

↓

Quality Inspection

The company reports more than 30 automated production lines and a 30,000 m² production facility. Its stated annual capacity includes 150,000 logistics carts and 150,000 storage cages.

For OEM buyers, in-house processing is useful because changes to dimensions, structure or finish can be coordinated within the same production system.

31. MOQ for OEM Roll Containers

MOQ depends on how much tooling, material preparation and customization are involved.

SUVA's published roll container information gives an MOQ of 20 pieces for its listed roll cage configuration, and its product page states that customized orders are accepted.

However, buyers should separate:

Standard product MOQ

from

Custom product MOQ

from

New-design/tooling MOQ

These may not be the same.

32. Customization and Cost

The main cost drivers are:

• Steel consumption
• Frame complexity
• Mesh specification
• Load capacity
• Caster specification
• Door mechanism
• Folding mechanism
• Surface treatment
• Logo/branding
• Packaging
• Tooling
• Quantity

For example, adding a stronger base may increase steel consumption, while adding a folding mechanism increases the number of components and assembly operations.

A useful OEM quotation should separate:

Product Cost + Customization Cost + Packaging Cost + Tooling Cost

33. Customization and Shipping Cost

A customization that improves warehouse operation can increase shipping cost.

For example:

Larger cage

→ More usable capacity
→ Fewer cages per container

Foldable cage

→ More components
→ Higher manufacturing cost
→ Better empty-space utilization

Heavy-duty cage

→ Higher load capacity
→ More steel
→ Higher unit weight

The right choice should therefore be based on total operating cost, not just the factory price.

34. Private Label Roll Container

For distributors, SUVA can provide private-label manufacturing, including logo and packaging customization.

A private-label specification can include:

• Brand logo
• Product label
• Color
• Packaging
• Product name
• Model number
• Barcode
• Carton markings
• Instruction label

For distributors selling the same cage in several markets, a common frame with different branding can simplify procurement.

35. Custom Roll Container for Retail Chains

A supermarket chain should consider the entire store network.

The OEM specification should account for:

• Store backroom dimensions
• Distribution center loading
• Delivery vehicles
• Store receiving areas
• Aisle width
• Elevator dimensions
• Employee handling
• Empty-cage return

For a multi-country retail group, also check whether the same cage needs to work with different pallets, trucks or warehouse systems.

36. Custom Roll Container for 3PL

3PL operators normally care about utilization and flexibility.

Recommended considerations:

• Nestable design
• Foldable side panels
• Durable casters
• Replaceable wheels
• Standardized dimensions
• Optional doors
• Barcode/ID plate
• High loading efficiency

A standardized cage fleet is easier to maintain than a collection of many slightly different models.

37. Custom Roll Container for E-Commerce

E-commerce warehouses often need:

• Smaller mesh opening
• Easy parcel access
• Higher usable volume
• Smooth casters
• Optional shelves
• Identification labels
• Foldability

SUVA lists e-commerce warehouses and third-party logistics among its roll container applications.

For parcel handling, the mesh should be selected according to the smallest parcel size rather than the largest carton.

38. Custom Roll Container for Heavy Industrial Use

For industrial parts, automotive components or manufacturing materials, consider:

• Reinforced base
• Heavy-duty casters
• Higher load rating
• Larger frame tubes
• Stronger welds
• Optional shelves
• Corrosion protection

SUVA's heavy-duty configurations can be customized according to load requirements, with published capacities reaching 1,000 kg on the detailed roll cage page and up to 1,500 kg in its general specification range.

42. Information to Send a Roll Container OEM Manufacturer

When requesting a quotation from SUVA or another manufacturer, provide this information:

The more complete this specification is, the less time will be spent going back and forth over basic dimensions and features.

43. Sample OEM Specification

For example, a buyer could send SUVA a requirement like this:

• Product: 3-Sided Roll Container
• Application: Supermarket distribution
• Overall Size: 850 × 670 × 1,750 mm
• Load Capacity: 500 kg
• Material: Steel
• Mesh: Customized according to sample
• Base: Reinforced steel tube
• Door: Single folding door
• Casters: 4 pcs, 2 swivel + 2 fixed
• Caster Diameter: 125 mm
• Surface: Powder coating
• Color: RAL 7016
• Logo: Front metal plate
• Folding: Required
• Nesting: Required
• Packaging: Export packing
• Quantity: 500 pcs
• Shipping: 40HQ
• Required Information: Unit weight + loading quantity + lead time

This is much easier for an engineering team to quote than:

"We need 500 custom roll cages."

44. Questions to Ask SUVA Before Ordering

Design

• Can you modify the standard dimensions?
• Can you redesign the frame?
• Can you provide CAD drawings?
• Can you make a prototype?

47. What Makes a Good Roll Container OEM Project?

For a customized roll container, the most important document is not the quotation. It is the approved technical specification.

The specification should connect five things:

Application → Structure → Function → Quality → Logistics

SUVA's existing capabilities make it possible to approach customization from these five areas. Its published roll container range covers different dimensions, load capacities, surface treatments, caster sizes, folding and nesting configurations, while its OEM/ODM service includes custom dimensions, branding, colors, structural optimization and packaging.

For a supermarket chain or logistics company ordering hundreds or thousands of units, the best OEM design is not necessarily the most complicated one. It is the design that fits the actual aisle, carries the required load, moves easily, survives repeated handling, can be repaired with available parts, and uses container space efficiently.

That is also why the prototype, loading test and final drawing should be approved before mass production. A small dimensional change at the design stage is inexpensive; changing hundreds of finished roll containers after production is not.
