Welded frame sized to the part or carton it carries
The fixture comes first: once we know the part, the shelf spacing, side guides and stops follow from it.
Industrial Transfer Cart / Warehouse Trolley
Made-to-order warehouse trolleys and transfer carts for moving parts, cartons and work in progress. Low-platform utility trolleys, shelf carts, rack carts or a purpose-built fixture — typical builds run tube Ø20–50 mm with 1.2–3.0 mm wall, deck plate 0.8–3.0 mm and casters 75–200 mm. We build to your drawing, around the load, the route and the aisle width.

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.
Internal transfer carts usually fail where the fixture meets the frame: shelves that deflect under a full load, dividers that bend, or a cart that cannot be pushed through the narrowest door on the route. Buyers also need the same cart again in six months, which means the drawing has to be repeatable.
Send a drawing, a photo of the part or a sample cart. We review the load, the part geometry, the fixture layout, tube section, caster rating, finish and packing, then confirm what we would change for manufacturability before quoting. Drawings and jigs are kept on file so a repeat order matches the first one.
The fixture comes first: once we know the part, the shelf spacing, side guides and stops follow from it.
Dividers, padded zones and rack arms are welded or bolted depending on whether the cart will ever be reconfigured.
Route length, floor joints and elevation changes decide wheel diameter and tread material.
Wash-down, outdoor and food-handling routes change both material and finish, so we ask before quoting.
Workshop Photos
Every photo on this page was taken in our own workshop or at our customer site. No stock images, no renderings.
Transfer cart — the fixture is designed around the part it carries.
Built to drawing — shelf spacing and guides follow one specific part.
Same cart from the side — rack pitch and base clearances set by the part geometry.
Mesh-side platform trolley — welded mesh keeps loose cartons and totes on the deck.
Front view — removable push handle, mesh on all four sides, flat steel deck.
A batch in final inspection before packing — repeat builds hold the same geometry.
Bolt-on casters with welded corner gussets — casters can be swapped in the field.
Customization
These options change material use, process route, tooling, assembly time, packing volume, and final cost.
Engineering Choices
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.
Tube size, plate thickness, reinforcement ribs, weld layout, and deck surface should match the real load, cargo footprint, and impact during use.
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.
Manual push handles, double handles, tow bars, coupling arms, forklift handling, or AGV interface requirements can be reviewed for custom projects.
Brake position, side rails, mesh guards, anti-slip decks, wheel locks, and load distribution help make the trolley safer during loading and parking.
Powder coating, galvanizing, stainless steel, or custom color should be selected based on indoor/outdoor use, corrosion exposure, and brand requirements.
Assembled, semi-assembled, knock-down, carton, pallet, and spare wheel packing options affect freight volume, assembly time, and after-sales support.
Quality Checks
Quality checks are adjusted according to the actual trolley type, structure, load, and application.

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
| 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 |
DFM and Inspection Review
A drawing can look complete and still leave the most expensive problems unresolved. Attach your drawing or reference photos and identify these points before quotation.

Manufacturing Process
The production route can include tube cutting, laser cutting, CNC bending, welding, surface treatment, wheel installation, final function checks, and export packaging. For OEM projects, drawings or samples help improve quotation accuracy.
FAQ
The shelf height, usable shelf depth, handle position, caster layout and turning clearance should match the cartons, bins and route used by the operator. A picking cart is designed around the sequence of work, not only its outside dimensions.
Yes. Share the narrowest aisle, turning space, largest carton, target load and floor condition. We can then review the frame width, handle projection, shelf arrangement and caster layout before quotation.
Please send cargo dimensions and weight, route distance, floor joints or thresholds, working frequency, parking condition, shelf or bin layout, quantity and packing target.
Yes. Overall size, platform size, shelf layout, cage size, handle height, and wheel configuration can be customized based on your use case.
Yes. Photos, samples, sketches, and use requirements can start the review. Drawings are recommended for accurate quotation and production.
Wheel choice depends on load, floor type, noise requirement, movement distance, brake needs, and whether the trolley is pushed, pulled, or parked on slopes.
Foldable handles, foldable cages, removable shelves, and knock-down packing can be discussed when storage space or freight volume is important.
Custom color, logo plate, label, carton artwork, and distributor packing can be reviewed for OEM and private-label trolley programs.
For heavy loads or long routes, please confirm tow bar, coupling arm, forklift, tugger cart, or AGV interface requirements during the RFQ stage.
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.
Yes. Those formats are accepted for review, and reference photos or samples are useful when the drawing does not show the working environment.
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.
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.
We can review assembled, semi-assembled or knock-down packing, including cartons, pallets, hardware bags, labels and finish protection according to the shipping plan.
Yes. Sample or first-article review can be discussed according to the drawing maturity, project quantity, tooling and approval process.
Send your trolley type, load capacity, size, wheel requirement, quantity, and drawings or reference photos. Our team will review the structure and reply within 24 hours on business days.
