FACTORY TRIAL ASSEMBLY OF STEEL STRUCTURES

Problems found on site are expensive, especially abroad. For complex nodes, trusses and multi-part members we trial-assemble the steel in the factory, check hole alignment and dimensions, and mark every piece before dismantling it for shipment. Your crew receives members that are proven to fit. Main frames are typically Q235 welded H section columns and beams.

Key advantages
  • Fits first time on site
  • Avoids costly site rework abroad
  • Clear marking for fast erection
  • Erection cost up to 30% lower
