About Wiberg Metal
Steel grating and access system manufacturer for industrial export projects. Fabrication to specification from Shanghai, China.
ISO 9001:2015
Current certified scope: production of steel grating.
Steel-Grating Manufacturer
Fabricated panels, HDG grating and stair treads documented in the supplied records.
Certificate Valid to 2028
ISO 9001 certificate remains subject to required surveillance audits.
Factory & Equipment
The legal manufacturer is identified consistently across the ISO certificate and voluntary VoC. Current evidence covers production of steel grating, with fabrication, inspection and export documentation aligned to the confirmed order scope.
Export packing and documentation teams work alongside production, so project labelling, packing lists, and mill certificates stay coordinated with the fabrication schedule.
Production Process
From raw material to finished product. Each step is tracked for consistency and traceability.
1Blanking
Raw steel cut to specification. Bearing and cross bars prepared per panel dimensions.
2Shaping
Bars formed for assembly. Serrated bars receive surface treatment for anti-slip.
3Welding
Automated pressure welders and robotic arms join bars at each intersection for consistent load-bearing strength.
4Cutting
Panels cut to final dimensions. Edge trimming to match project drawings.
5Galvanizing
Hot-dip galvanizing to ASTM A123 / EN ISO 1461. Zinc coating verified per batch.
6Quality Inspection
Dimensional checks, surface and weld verification. Material certificates and test reports per order.
7Packing
Export packing with protective wrapping. Bundles labelled and marked for destination identification.
8Warehouse & Shipping
Finished products stored and prepared for shipment. Container loading coordinated with documentation.
