Match The Decision To The Equipment Family
Use the product pages to check the physical model, then confirm the project-specific drawing, load, finish, and packing scope.Quick Buyer Answer
A shelf rating is only useful when the span, depth, bracket, steel thickness, load pattern, and deflection limit match the ordered configuration. CZD's 4-post retail reference is 70 kg per shelf, while warehouse pallet and platform systems use different load units and must be specified separately.
Use the guide below as a conversation starter with your supplier. You do not need a perfect specification before asking for help; the important thing is to make the open decisions visible and compare like with like.
Decision Snapshot
Approve the load as a complete shelf configuration, not a catalog headline. Require the test setup, load pattern, span, bracket, deflection result, stability condition, and production part code before releasing a heavy merchandise zone.
| Load gate | Evidence to request | Why it matters |
| Geometry | Span, depth, bracket, stiffener and upright | A different bay can have a different result |
| Load pattern | UDL, case stack, point or hook load | Real products rarely load a shelf identically |
| Result | Deflection, permanent set and hold time | Protects appearance and safe operation |
| Traceability | Part code, test date and approved drawing | Keeps reorders and repairs compatible |
What To Send For A Quote
- Heaviest SKU, case dimensions and shelf position
- Required bay length, depth, levels and brackets
- Public-access, anchoring and local code constraints
- Acceptance limit and sample-bay test plan
A retail shelf capacity number is not a universal property of every shelf in a product family. Span, depth, bracket geometry, steel thickness, reinforcement, upright stability, load distribution, and allowable deflection all change the result. A buyer should approve the exact configuration that will carry the heaviest merchandise, not copy a number from a different bay.
CZD's 4-post retail reference lists Q235B cold-rolled steel, five levels, 900/1200 mm lengths, 365 mm single-sided width, 700 mm double-sided width, and a 70 kg capacity reference. That is a useful starting point for an RFQ; the final drawing and test condition must match the project.
Define The Real Load Pattern
Describe whether the shelf carries uniformly distributed packs, concentrated cases, beverage trays, pet food, hooks, or a promotional fixture. Tell the supplier the heaviest SKU, case dimensions, shelf position, replenishment method, and whether staff may temporarily stack cartons during delivery. A 70 kg uniformly distributed reference cannot automatically be applied to a concentrated case stack.
| Load pattern | Buyer detail | Why it changes approval |
| UDL | Weight spread across the shelf | Common catalog reference |
| Case stack | Footprint, height and contact points | Creates local stress |
| Hook or fixture | Point load and pull-out force | Bracket and back-panel demand |
| Mixed merchandise | Worst credible arrangement | Tests real store behavior |
Approve The Complete Geometry
Request a drawing that states clear span, shelf depth, front lip, reinforcement, bracket type, upright slot pitch, back panel, base connection, and installation method. The same 900 or 1200 mm nominal length can perform differently when the bracket, depth, or stiffener changes. Record the usable merchandising dimension as well as the outside dimension.
| Parameter | CZD retail reference | Confirm for the order |
| Length | 900 / 1200 mm | Clear span and facings |
| Width | 365 mm single / 700 mm double | Finished footprint and aisle |
| Height | 1500 / 1700 / 2100 / 2300 mm | Reach, stability and sightline |
| Capacity | 70 kg reference | Load pattern, deflection and hold time |
Ask For Deflection And Stability Evidence
A useful test record shows load placement, increments, hold time, measured deflection, permanent set after unloading, connections, and floor or anchoring conditions. Tall runs and heavily loaded lower shelves also need stability review across uprights, feet, back panels, and the floor. Follow local accessibility, anchoring, and public-area requirements.
Keep The Approved Rating In The Store
Store the drawing, test result, component code, approved bracket, and load condition with the installation and operations teams. Do not mix shelves, brackets, or uprights from another family without review. Mark or communicate the approved load where staff replenish products, and replace damaged structural parts instead of improvising repairs.
Use A Sample Bay With Real Products
Load a sample bay with the heaviest and most concentrated products. Check facings, deflection, bracket fit, stability, customer reach, replenishment, ticket visibility, and installation time. CZD can combine 3D design, customized thickness or fittings, sample-bay direction, and a preliminary BOM before the wider order is released.
Next Step For Your Project
Send the product weights, load patterns, bay dimensions, shelf positions, and store constraints. CZD Shelves can match the appropriate retail shelf family and prepare a configuration-specific capacity, sample, drawing, and BOM direction.
