Application First
The cargo, route, floor and operating frequency decide the trolley structure.
Metal Trolley Manufacturer - Factory Direct, Ningbo China
We are a factory, not a trading company. We build metal trolleys on wheels: platform trucks, book trucks, hand trucks, warehouse and transfer carts, plus any other wheeled steel or stainless structure made to your drawing. The process is always the same - laser cutting, bending, welding and powder coating. What changes is the tube diameter, the sheet thickness and the frame structure. Tell us what the trolley has to carry and where it has to run.
Have only a photo or rough idea? That is enough to start the discussion. Add the target load, overall size, wheel preference and quantity whenever available.
The cargo, route, floor and operating frequency decide the trolley structure.
Laser cutting, CNC bending, tube work, welding, finishing and assembly work as one route.
Product pages explain the details your engineering or purchasing team needs to confirm.
Drawing revision, wheel model, finish, labels and packing should stay controlled from sample to reorder.
Factory Behind Doing Metal
Doing Metal is the trolley-focused export site of Fulei Metal. A custom trolley is not only a frame and four wheels: it may include laser-cut decks, bent shelves, caster plates, handles, guards, mesh panels, drawers, surface treatment and final assembly.
That is why we organize the project around the way a buyer actually approves a supplier: application review, design-for-manufacturing discussion, sample or first-article confirmation, production inspection and protected export packing.
Fulei Metal company materials and the 2024 audit record provide a starting point for supplier review: a 2,500 m2 company area, 22 employees including 14 production staff, and a manufacturing route covering cutting, bending, welding, polishing, assembly and packing. Current project capability, documents and compliance evidence are confirmed during the RFQ.

Commercial Fit
Doing Metal is intended for importers, distributors, OEM brands and industrial teams that need an engineered trolley, controlled revisions and a realistic production quantity.
A sample or first article can be built from 1 to 3 units so you can check the frame, welds, wheels, finish and packing before committing to a production quantity. The sample cost is credited against your first production order.
Trial and market-testing orders from 10 to 20 units are workable once the drawing is frozen. This suits new distributor programs, catalogue launches and niche applications.
Standard production programs run from 50 units, where material purchasing, wheel sourcing, finish setup, inspection and export packing give the clearest cost basis.
Trolley Product Families
Use these families as a starting point. If your trolley is not listed here, it is still a metal frame on wheels - send the drawing and we will build it. Each page explains the buyer problem, design choices, inspection points and the information needed for a useful quotation.

Flatbed carts for bulky or heavy goods. Confirm deck size, load, reinforcement, handle, caster layout and braking.
Explore platform trolley
Picking and stock-transfer carts shaped around aisle width, carton size, shelf layout, route distance and daily use.
Explore warehouse trolley
Mesh and roll-cage carts for containment, visibility and staged inventory, with fixed, folding, door and lock options.
Explore cage trolley
Mobile workshop storage with trays, drawers, pegboards, hooks, locks, anti-slip surfaces and brake casters.
Explore tool trolley
Quiet, stable carts for books, files and archives where shelf lips, smooth edges, turning space and appearance matter.
Explore library trolley
Equipment carts planned around camera cases, lights, cables, monitors, dividers, protection, quiet movement and parking.

A product photo cannot tell us enough to select the right frame or wheels. These five inputs turn a general request into an engineering-ready RFQ.
From RFQ to Reorder
Send cargo, load, route, floor, size, quantity and a photo or drawing.
Confirm frame, deck or shelf layout, wheels, handle, finish and packing.
Check fit, movement, braking, appearance and the critical dimensions.
Keep the approved drawing, wheel model, finish and packing version consistent.
Review function, finish, accessories, quantity and export protection.
Export Packing
Nothing loses a reorder faster than a pallet of scuffed frames. Packing method is agreed with the drawing — stack pattern, separation, wrapping and container loading — and treated as an inspection item before booking.

Cartons prepared per unit so nothing arrives short.

Shrink wrap and corner protection against rubbing in transit.

Finished surfaces masked and separated before palletising.

Labelling and carton marking to your artwork.
