Metal Trolley Manufacturer - Factory Direct, Ningbo China
Custom Metal Trolleys, Built to Your Drawing
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.

Ningbo, China
Samples from 1 unit, production from 50
OEM and repeat-order support
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.
Fabrication Connected
Laser cutting, CNC bending, tube work, welding, finishing and assembly work as one route.
Buyer-Ready RFQ
Product pages explain the details your engineering or purchasing team needs to confirm.
Repeat-Order Thinking
Drawing revision, wheel model, finish, labels and packing should stay controlled from sample to reorder.
Factory Behind Doing Metal
A Trolley Website Backed by a Real Sheet Metal Manufacturing Route
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.
One programme shows how that holds up over repeat orders: a Korean library equipment brand that started with an all-steel book trolley, moved the shelves to aluminium, added black and grey alongside white, then added a large H-frame cart mid-programme. Read the library trolley case study for the drawing changes, the material decision and the review rhythm behind two years of continuous orders.
Fulei Metal company materials and the 2026 Bureau Veritas audit (Report No. MIC-ASR263630) provide a starting point for supplier review: four production lines covering laser cutting, CNC bending, welding and polishing, ten years of export experience serving 165 customers, and a manufacturing route from raw material through assembly to export packing. Current project capability, documents and compliance evidence are confirmed during the RFQ.
Commercial Fit
Built for Buyers Who Need a Repeatable Trolley Program
Doing Metal is intended for importers, distributors, OEM brands and industrial teams that need an engineered trolley, controlled revisions and a realistic production quantity.
Samples from 1 unit
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 orders from 10 units
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.
Production from 50 units
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
Choose the Structure That Matches the Job
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.

Five Questions That Prevent the Wrong Cart
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.
1. What is the heaviest real load, and is it evenly distributed?
2. What are the aisle width, turning space and floor conditions?
3. Does the cart need shelves, mesh, drawers, dividers or a flat deck?
4. Is the environment dry, humid, washdown, outdoor, quiet or ESD-sensitive?
5. Will it ship assembled, knock-down, nested or under a private label?
From RFQ to Reorder
A Clear Manufacturing Conversation Before Batch Production
Describe the use
Send cargo, load, route, floor, size, quantity and a photo or drawing.
Review the structure
Confirm frame, deck or shelf layout, wheels, handle, finish and packing.
Approve the sample
Check fit, movement, braking, appearance and the critical dimensions.
Control production
Keep the approved drawing, wheel model, finish and packing version consistent.
Inspect and ship
Review function, finish, accessories, quantity and export protection.
Export Packing
Four Weeks at Sea Should Not Undo the Build
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.
