| 1. Define the load profile first |
Pallet weight: 500–1,500 kg
Typical unit-load pallet depth: 1,000–1,200 mm
|
Confirm pallet dimensions, load stability, load distribution, SKU turnover, and the number of pallets per SKU before requesting quotations.
|
The rack design should be checked against the structural design rules required in the destination market. Point-load assumptions must be documented.
|
Design and engineering allowance: approximately US$500–3,000 per project, depending on warehouse size and complexity.
|
Require a signed load schedule, rack elevation drawings, anchor details, and a statement identifying the maximum permissible bay and beam loads.
|
| 2. Select the right rack configuration |
Selective pallet rack: commonly 2–4 pallets deep per bay.
Drive-in or drive-through rack: often 4–10 pallets deep.
|
Compare storage density, forklift selectivity, inventory rotation, pallet access, fire protection constraints, and future reconfiguration options.
|
First-in, first-out requirements generally favor selective or drive-through solutions; last-in, first-out operations may suit drive-in layouts where appropriate.
|
Installed selective-rack systems commonly fall around US$100–300 per pallet position, excluding major building work.
|
The installer should verify aisle widths against the selected forklift, rack geometry, turning radius, mast height, and required operating clearances.
|
| 3. Check the governing standards |
Common references include EN 15635, RMI MH16.1, FEM 10.2.02, and AS 4084.
|
Ask whether the supplier designs, manufactures, labels, inspects, and installs according to the standard applicable to the warehouse location.
|
EN 15635 covers the use and maintenance of steel static storage systems; RMI MH16.1 is used for industrial steel storage racks in North America; AS 4084 applies in Australia and New Zealand.
|
Compliance documentation and engineering calculations may add approximately 5–15% to the equipment package.
|
Request certificates, calculation reports, material specifications, welding or forming quality records, and the latest revision of installation instructions.
|
| 4. Compare steel quality and protection |
Upright and beam thickness should be based on calculated loads, not appearance alone. Common finishes include powder coating and galvanized steel.
|
Compare yield strength, steel thickness, coating system, corrosion resistance, weld quality, connector design, and replacement-part availability.
|
Product documentation should identify the steel grade, protective coating, allowable loads, and inspection or testing method used by the manufacturer.
|
Galvanized or corrosion-resistant finishes generally cost about 10–30% more than standard indoor powder-coated finishes.
|
For humid, coastal, refrigerated, or chemically exposed environments, require a corrosion assessment and a written coating warranty.
|
| 5. Validate seismic and floor conditions |
Floor flatness, concrete strength, slab thickness, anchor capacity, and seismic design category can materially change the rack design.
|
Compare suppliers using the same floor survey, site measurements, seismic parameters, rack height, and stored-load assumptions.
|
Seismic design must follow the building regulations and structural standards applicable to the installation country and local authority.
|
Floor repairs, engineering surveys, and seismic upgrades may add approximately US$5–30 per pallet position.
|
Require pre-installation slab testing, anchor pull-out verification where necessary, and a documented acceptance check after installation.
|
| 6. Design aisles for the actual forklift |
Typical clear aisle ranges: 2.7–3.7 m for many counterbalance or reach-truck applications; exact values depend on the truck model and load.
|
Compare the supplier’s aisle calculation with the forklift manufacturer’s turning radius, load length, fork length, and required operating clearance.
|
OSHA 1910.176 and comparable local workplace-safety rules require safe clearance, stable storage, and unobstructed material-handling areas.
|
Narrow-aisle or very-narrow-aisle layouts can reduce floor-area requirements but may increase equipment and guidance-system costs by approximately 15–40%.
|
Include forklift trials or a full-scale floor simulation before final approval, especially for narrow aisles and high-level storage.
|
| 7. Include safety accessories |
Common accessories include column guards, end-of-aisle barriers, pallet supports, wire decking, back guards, row spacers, and safety pins.
|
Compare accessory coverage, impact ratings, compatibility with the rack frame, replaceability, and whether accessories are included in the quoted price.
|
EN 15635 and local workplace regulations emphasize protection against impact, overloading, falling materials, and unauthorized rack modification.
|
Safety accessories typically add approximately 10–25% to the rack hardware package, depending on protection density.
|
Require a safety handover pack containing load signs, inspection procedures, damage-report forms, and a list of approved replacement parts.
|
| 8. Compare the total landed cost |
Evaluate equipment, packaging, inland transport, ocean or air freight, insurance, duties, taxes, unloading, installation, and commissioning.
|
Request quotations using the same Incoterm, currency, quantity, delivery point, packaging standard, warranty period, and payment assumptions.
|
Import classification, customs documentation, product liability, and local installation requirements vary by country and should be verified before purchase.
|
Freight, duties, and local handling can add approximately 15–35% to the ex-works equipment price on international projects.
|
Ask for a line-item commercial schedule and confirm responsibility for unloading, storage before installation, customs clearance, and damaged-goods claims.
|
| 9. Audit supplier capability without relying on brand names |
Review production capacity, quality-control checkpoints, engineering resources, export experience, lead time, and service coverage.
|
Compare independent test reports, reference projects by application type, dimensional tolerances, nonconformance procedures, and spare-part lead times.
|
A quality-management certification such as ISO 9001 can support process evaluation, but it does not replace structural calculations or local compliance approval.
|
Third-party inspections or factory audits often cost approximately US$500–2,500 per visit, excluding travel.
|
Use a pre-shipment inspection covering dimensions, coating, welds, accessories, quantity, packaging, labels, and conformity with approved drawings.
|
| 10. Secure installation, training, and lifecycle support |
Installation duration commonly ranges from 1–5 days per 1,000 pallet positions, depending on height, layout, floor conditions, and access.
|
Compare installer qualifications, supervision, method statements, safety planning, commissioning records, response time, and annual inspection options.
|
EN 15635 recommends regular user inspections and a formally organized inspection process; local occupational-safety rules may impose additional requirements.
|
Installation commonly costs approximately US$25–80 per pallet position; annual inspections may cost about US$500–2,500 per site.
|
Require trained installers, torque or anchor records, plumbness checks, load-sign installation, operator training, commissioning, and a post-installation safety inspection.
