From steel coil to finished racking
All structural components are made in-house so tolerances, coating and load ratings are under one roof.
1. Roll-forming
Uprights (90 × 70 to 120 × 95 mm) and box or step beams are roll-formed from Q235 / Q355 coil in 1.5–3.0 mm, with 50 mm or 75 mm pitch punching on the same line.
2. Welding
Beam connectors, frame bracing and base plates are welded in robotic cells; cantilever arms and mezzanine columns are jig-welded and checked for squareness.
3. Pre-treatment and powder coating
Nine-stage pickling and phosphating, electrostatic powder coating and 200 °C curing give 60–80 µm film thickness. Hot-dip galvanising is available for outdoor and cold-store use.
4. Quality control
Beam deflection and frame load tests per FEM 10.2.02, coating thickness and adhesion checks, and dimensional inspection of every batch. Test reports ship with the goods.
5. Packing
Frames, beams and decks are bundled on steel pallets or in plywood crates with a container loading plan, so installers receive labelled parts in build order.
