Welded mesh panels to your mesh size and wire gauge
Mesh size and wire gauge drive both the weight and the welding time, so they are the first two numbers to fix.
Cage Trolley / Roll Cage / Roll Container
Cage Trolleys and Roll Containers Built to Your Drawing
Wire mesh cage trolleys, folding roll containers and shelf roll cages, built to your drawing or sample — not kept as a stock line. Typical builds run Ø5–6 mm mesh wire on 25–32 mm tube frames, 500–800 kg load class, with folding and nesting designs for return logistics. Send the mesh size, wire diameter, door and lock requirement and target load, and we review the structure, welding sequence, nesting and packing before quoting.

Product Overview
Built Around Load, Movement, Storage and Safety
Doing Metal can customize trolley structure based on your drawings, product photos, sample design, working environment, and quantity target. We review frame strength, caster layout, platform or shelf design, finish, and packing before quotation.
Buyer Problem and Custom Solution
Cage buyers want containment and visibility without paying for a cage that is heavier than the job needs, and they want it to survive being pushed into a truck bay every day. The usual weak points are the hinge on folding designs and the base frame where the mesh terminates.
Doing Metal Solution
Send a drawing or a photo of the cage you use now, with the load, the mesh specification, whether it needs to fold or nest, and the quantity. We will confirm what we can build and where the design should be adjusted for welding and packing.
Folding roll container designs that nest flat for return freight
Folding and nesting designs cut empty return volume dramatically, but the hinge and locking points have to survive daily folding — that is where our jig and weld detail matter.
Fixed, folding or removable side panels and wire shelf tiers
Wire shelf tiers turn a roll container into a picking cage for small cartons; tier positions are set on the drawing, not drilled later.
Zinc-plated, galvanized or powder coated fleet colours
Hot-dip galvanizing suits outdoor and wet logistics routes; powder coat gives retail and laundry fleets a clean branded colour.

Engineering Choices
Key Details That Change Trolley Performance and Cost
Foreign material handling buyers often compare the same trolley by load class, wheel system, ergonomic design, towing method, surface finish, and packing. Confirming these details early helps avoid under-built carts and unnecessary cost.
Frame and Deck
Tube size, plate thickness, reinforcement ribs, weld layout, and deck surface should match the real load, cargo footprint, and impact during use.
Caster Layout
Two fixed plus two swivel wheels, four swivel wheels, brake casters, pneumatic tires, or larger PU wheels can be selected for different routes and floor conditions.
Push, Pull or Tow
Manual push handles, double handles, tow bars, coupling arms, forklift handling, or AGV interface requirements can be reviewed for custom projects.
Safety and Parking
Brake position, side rails, mesh guards, anti-slip decks, wheel locks, and load distribution help make the trolley safer during loading and parking.
Finish Durability
Powder coating, galvanizing, stainless steel, or custom color should be selected based on indoor/outdoor use, corrosion exposure, and brand requirements.
Export Packing
Assembled, semi-assembled, knock-down, carton, pallet, and spare wheel packing options affect freight volume, assembly time, and after-sales support.
Quality Checks
Inspection Points for This Trolley Type
Quality checks are adjusted according to the actual trolley type, structure, load, and application.
Mesh weld strength at frame joints
Panel alignment and gap check
Hinge and lock function cycling
Caster rolling and brake test
Frame squareness and diagonal check
Finish and packing protection inspection
Angle and squareness checked against a template on every welded frame.
Joint-by-joint angle checks happen during assembly, not only at final inspection.
Same gauge, same angles — that is how unit 500 matches unit 1.
Specifications
Custom Trolley Specification Options
| Item | Options to Confirm |
|---|---|
| Load Capacity | Confirmed from the actual cargo, load distribution, route, floor and safety factor; the quotation should not rely on a generic load class alone |
| Sheet / Tube Thickness | Confirmed from material grade, load path, part geometry and downstream process. Current thickness limits are reviewed against the selected machine and drawing. |
| Material | Carbon steel, stainless steel, aluminum, steel mesh, or combined structure |
| Size | Standard or custom platform, shelf, cage, or drawer dimensions |
| Wheel Type | PU, rubber, nylon, pneumatic, fixed, swivel, brake caster, or heavy-duty caster |
| Structure | Flat platform, shelves, side rails, cage, drawers, foldable handle, knock-down packing |
| Finish | Powder coating, galvanizing, stainless finish, custom color, or other finish as required |
| MOQ / Sample | Standard MOQ is 50 units. For large-size or heavy-duty trolley projects, quantities from 10 units may be discussed. Sample and first-article arrangements are reviewed separately. |
| Lead Time | Quoted after drawing, material, quantity, finish, wheel sourcing and packing are confirmed |
| Packing | Fully assembled, semi-assembled, knock-down, carton, pallet and spare-part options |
| Branding | Logo, label, custom color, private-label packing, and distributor program support |

Load path from deck or shelves into the welded frame
Handle height, reach, turning space and operator access
Hole, slot and bend clearance around assembly interfaces
Finish build-up around threads, hinges and moving parts
Assembled or knock-down packing volume and protection

FAQ
Common Questions Before Ordering Custom Trolleys
What mesh opening should a cage trolley use?
The opening should be smaller than the smallest item that must stay inside, while still allowing visibility, cleaning and fast loading. Send the package or carton size so the mesh and divider layout can be reviewed.
Can a roll cage warehouse trolley be folded or nested?
Yes. Folding or nesting requires clearance at hinges, doors, mesh panels, casters and the coated surfaces. The empty-cart storage target should be confirmed before the frame is finalized.
Where should the door and brake be placed?
Door access should face the loading side and avoid the normal aisle route. Brake access should be reachable when the cart is parked and should not be blocked by the cage, shelf or cargo.
Can you customize the size?
Yes. Overall size, platform size, shelf layout, cage size, handle height, and wheel configuration can be customized based on your use case.
Can I send a photo instead of a drawing?
Yes. Photos, samples, sketches, and use requirements can start the review. Drawings are recommended for accurate quotation and production.
Which wheel should I choose?
Wheel choice depends on load, floor type, noise requirement, movement distance, brake needs, and whether the trolley is pushed, pulled, or parked on slopes.
Can the trolley be foldable?
Foldable handles, foldable cages, removable shelves, and knock-down packing can be discussed when storage space or freight volume is important.
Do you support OEM branding?
Custom color, logo plate, label, carton artwork, and distributor packing can be reviewed for OEM and private-label trolley programs.
Can it work with towing equipment?
For heavy loads or long routes, please confirm tow bar, coupling arm, forklift, tugger cart, or AGV interface requirements during the RFQ stage.
What is the MOQ?
Our standard MOQ is 50 units for most custom trolley programs. For large-size or heavy-duty projects, quantities from 10 units may be discussed after reviewing the structure, material, casters, finish and packing. Samples and first articles are handled separately.
Can you quote from a PDF, DWG, DXF or STEP file?
Yes. Those formats are accepted for review, and reference photos or samples are useful when the drawing does not show the working environment.
How is lead time confirmed?
Lead time is confirmed after the drawing revision, material, quantity, finish, wheel model and packing method are agreed. We avoid giving a generic date that does not fit the project.
Can you provide supplier approval documents?
Tell us which documents your purchasing team needs. Material, inspection, packing and project records can be discussed, while certifications are published only after internal verification.
How will the trolley be packed?
We can review assembled, semi-assembled or knock-down packing, including cartons, pallets, hardware bags, labels and finish protection according to the shipping plan.
Can I request a sample or first article?
Yes. Sample or first-article review can be discussed according to the drawing maturity, project quantity, tooling and approval process.
