High |
| Applicable Technical Standards |
Whether the design and installation method are aligned with the destination market and the selected racking type. |
Technical compliance statement, design calculations, test reports, installation manuals, and inspection procedures. |
For European projects, EN 15512:2020 is relevant to adjustable pallet racking design; EN 15635:2008 addresses use and maintenance of storage equipment. |
Specify the required national or regional standard before quotation and verify that the proposed design documents reference the same standard. |
High |
| Steel Material Traceability |
Whether steel grades, thicknesses, and incoming material batches can be traced to finished components. |
Mill test certificates, purchase records, material identification, incoming inspection reports, and batch traceability records. |
Material certificates should identify grade, thickness, mechanical properties, heat or batch information, and the supplying mill or processor. |
Select random finished components and trace them backward to inspection records and original material documentation. |
High |
| Production Equipment |
Whether the factory has suitable equipment for roll forming, punching, cutting, welding, coating, and component assembly. |
Equipment list, machine nameplates, maintenance logs, calibration records, production-line photographs, and live video or audit observations. |
Core processes should be performed under controlled conditions with maintained equipment and documented process parameters. |
During a factory audit, match the equipment list with machines on site and observe at least one complete production sequence. |
High |
| Factory Capacity |
Whether available capacity can support the required volume without excessive outsourcing or schedule risk. |
Production-line count, shift pattern, recent output records, order backlog, warehouse capacity, and subcontracting declarations. |
Capacity should be assessed against the buyer's peak monthly requirement, required delivery window, and confirmed utilization rate rather than a maximum marketing figure. |
Request three months of production data, inspect work-in-progress, and calculate available capacity after existing confirmed orders. |
High |
| Powder-Coating Process |
Whether surface preparation, powder application, curing temperature, and coating thickness are controlled. |
Process specifications, oven temperature records, coating-thickness reports, adhesion tests, and powder batch records. |
The required coating thickness and corrosion-performance target should be stated in the purchase specification because requirements vary by environment and standard. |
Inspect pretreatment and curing lines, review recent test records, and perform independent coating-thickness checks on sampled parts. |
High |
| Welding and Fabrication Control |
Whether welded frames, guards, supports, and accessories are produced using approved procedures and competent operators. |
Welding procedure documents, operator qualification records where applicable, inspection checklists, and sample weld inspection reports. |
Welds should be visually inspected against documented acceptance criteria, with additional testing where the project specification requires it. |
Review procedure documents and inspect representative welded components for consistency, distortion, incomplete fusion, and surface defects. |
High |
| Quality Inspection Plan |
Whether inspections occur at incoming-material, in-process, final-assembly, and pre-shipment stages. |
Inspection and test plan, sampling procedures, dimensional reports, nonconformance records, and final inspection checklists. |
Inspection records should include component dimensions, steel thickness, hole positions, coating condition, packaging, and quantity verification. |
Ask for anonymized records from recent orders and compare the recorded measurements with the approved drawings and tolerances. |
High |
| Independent Testing |
Whether critical components or complete systems have been evaluated by a competent third party when required by the project. |
Laboratory test reports, scope of accreditation, sample identification, test date, applied standard, and tested configuration. |
A valid report must clearly identify the tested product, configuration, loads, test method, laboratory, and report number. |
Contact the laboratory directly or verify its accreditation status; do not accept certificates that only show a logo without traceable details. |
High |
| Installation and After-Sales Support |
Whether the supplier can provide installation guidance, inspection support, replacement parts, and corrective-action assistance. |
Installation manual, inspection checklist, spare-parts list, response-time policy, warranty terms, and service references. |
Documentation should define anchoring, safe loading, component replacement, damage reporting, and periodic inspection responsibilities. |
