Stainless Steel Trolley / Wash-Down Cart
Grade 304 or 316 stainless steel trolleys for routes where powder-coated carbon steel will eventually rust: wash-down areas, food production, cold stores, chemical handling, laboratories and outdoor sites. Stainless construction changes more than the material — welding method, joint design, drainage, surface finish and the caster specification all change with it, so we review the cleaning method and the environment before quoting.

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.
Buyers specify stainless after a coated cart rusted, then discover the second cart rusted too — usually at the weld, at a zinc-plated fastener or under a trapped ledge holding water. Specifying the grade without specifying the joint design, finish and hardware repeats the same failure in a more expensive material.
Describe the environment: what the cart carries, what it is cleaned with and how often, temperature range, whether it is outdoors or near salt air, floor condition, load, quantity and any requirement for material certificates. We then confirm grade, sheet thickness, joint design, surface finish (brushed, bead-blasted or electropolished where required), caster and hardware specification, and quote from a drawing.
304 handles most food and indoor environments; 316 earns its cost where chlorides, salt or aggressive cleaning agents are present. Tell us what touches the cart and how often.
The weakest point on a stainless cart is usually the weld and the heat-affected zone next to it, not the sheet itself.
Open tubes, blind joints and trapped ledges hold water and product residue — design for drainage and access, or inspections will find it later.
Zinc-plated casters on a stainless frame rust first, which defeats the point of specifying stainless at all.
Workshop Photos
Every photo on this page was taken in our own workshop or at our customer site. No stock images, no renderings.
Hygiene specification — grade, weld finish and drainage design reviewed together.
In production — repeat orders held to the same material certificates and drawing.
Packed for dispatch — protected so it arrives inspection-ready.
Wrapping — stainless surfaces are protected against scuffs in transit.
Inspection — dimensions and squareness checked against the drawing.
Built in-house — stainless, carbon steel and aluminium work on the same floor.
Customization
These options change material use, process route, tooling, assembly time, packing volume, and final cost.
Buyer Decision Guide
Use this section before sending an RFQ. It translates the search term into the practical design points our team needs to review.
| Decision Area | What to Confirm | Why It Matters |
|---|---|---|
| Grade | 304 or 316, decided by chlorides and cleaning agents | 316 costs more but is the right answer near salt, brine and aggressive sanitisers |
| Finish | Brushed, bead blasted or electropolished | Rougher surfaces hold product residue and are harder to clean down to audit standard |
| Hardware | Stainless casters, bearings and fasteners as a set | Mixing zinc-plated hardware into a stainless frame moves the rust to the cheapest part |
| Cleaning | Manual wipe, pressure wash, or chemical fogging | Decides joint design, sealed tubes, drainage and the ingress rating of bearings |
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.

FAQ
304 suits most food, laboratory and indoor environments. 316 is the right choice where chlorides, salt air or aggressive cleaning agents are present. Describe what touches the cart and how often it is cleaned, and we will confirm the grade.
Yes, if corrosion resistance is the reason for specifying stainless. Zinc-plated casters and bolts on a stainless frame rust first, which defeats the point of the material change.
Material certificates can be provided per project requirement. State the documentation you need during RFQ so it is included in the quotation rather than added late.
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.
