Shelf count and pitch set from the items carried on each level
Shelf pitch is usually the tallest item plus clearance per level — too much pitch wastes vertical space in every aisle.
Multi-Tier Shelf Trolley / Utility Service Cart
Multi-Tier Shelf Trolleys Built Around Your Load
Two, three or four tier shelf trolleys for everything between a flatbed and a cabinet: totes, formed parts, components awaiting assembly, catering or retail stock, or library and office material. Shelf pitch, edge lips, dividers, side containment and the caster layout are set from what goes on each level. Tube section, plate thickness and finish follow the load and the environment.

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
Multi-tier carts fail in predictable ways: shelves that bow under the real load, lips too low to stop items sliding off when the cart turns, posts that loosen after a season of rolling over floor joints, or frames too tall to pass the door at the end of the route. Most of these are drawing-level decisions made before the first weld.
Doing Metal Solution
Tell us what goes on each level, the weight per shelf not just the total, the overall height limit if there is one, the door and aisle widths on the route, and whether the cart has to nest, stack or knock down for shipping. We then review post and shelf structure, tray material and thickness, edge treatment, caster layout and finish, and quote from a drawing.
Flat trays, lipped trays, wire decks or perforated shelves
Perforated or wire shelves keep weight down and let dust and liquids fall through; solid trays suit small parts and spill-prone loads.
Dividers, side rails or mesh panels for mixed loads
Dividers stop categories mixing during transport, which matters more than load capacity in most stock rooms and workshops.
Foldable, removable or fixed handles for storage and shipping
Removable handles and knock-down shelf designs cut container volume when you are shipping hundreds of units at a time.
Workshop Photos
What We Actually Build, Photographed in Our Own Workshop
Every photo on this page was taken in our own workshop or at our customer site. No stock images, no renderings.
Repeat batch — same geometry, same finish, ready for export packing.
Purpose-built racks — when the part geometry decides the frame, not the catalogue.
Side view — rack pitch and base clearance follow the part itself.
Mesh and welded panels — our own line, from tube stock to finished frame.
Casters — load per wheel is checked against rating, not averaged across the cart.
Finished carts staged — stackable designs reduce freight per unit.

Buyer Decision Guide
Details That Decide Whether This Trolley Will Work in Daily Use
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 |
|---|---|---|
| Load per shelf | Weight on the heaviest level, not the cart total | One overloaded shelf is how most multi-tier carts end up with a permanent bow |
| Containment | Whether items slide, spill or stack above the lip | Decides lip height, side rails, mesh panels or a fully open frame |
| Height limits | Door heights, lifts, mezzanine clearances | A cart that cannot reach the loading dock is a cart nobody uses |
| Shipping | Assembled, knocked down, stacked or nested | Can change landed cost more than any unit price negotiation |
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.
Shelf deflection under rated load per level
Post and bracket joint inspection
Handle height and rigidity check
Rolling test with the top shelf loaded
Finish inspection on visible edges
Packing and stacking protection check
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 |

FAQ
Common Questions Before Ordering Custom Trolleys
Solid trays or perforated shelves?
Solid trays suit small parts and liquids; perforated or wire shelves let dust fall through and keep the cart lighter. Choose based on what sits on the shelf, not on appearance.
What stops items sliding off when the cart turns?
Lip height, side rails, mesh panels or dividers. The right choice depends on how much the load shifts on your route, so describe the items and the route when you send the RFQ.
Can the trolley knock down or nest for shipping?
Yes. Removable handles, bolt-on posts and knock-down shelf designs cut container volume significantly on large orders. The trade-off is assembly time at your end, so we quote both versions.
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.
