For international steel construction projects, 100% bolted field connections are overwhelmingly superior to on-site field welding. In SerBuild pre-engineered buildings, all structural welding is performed under strict ISO 3834-2 and EN 1090-2 factory-controlled conditions using automated submerged-arc robots. On site, columns, rafters, purlins, and bracings are assembled exclusively using certified high-strength Grade 8.8 and 10.9 structural bolts. This eliminates on-site hot work permits, fire hazards, expensive radiographic weld testing (NDT), and specialized certified site welders.

Réponses détaillées sur l'ingénierie Eurocode, la fabrication, l'exportation et le montage.
Yes. Pre-engineered bolted moment connections are designed per Eurocode 3 (EN 1993-1-8) using high-strength Grade 8.8 and 10.9 structural bolts with heavy endplates, transferring full axial, shear, and bending moment forces with complete safety.
Field welding burns away the anti-corrosion paint and galvanization coating, creating localized zones vulnerable to rapid rust. Bolted connections preserve the factory paint warranty intact.
Quality verification is fast and objective: an inspector uses a calibrated torque wrench to verify that every bolt is tightened to the required torque specification listed in our erection drawings.
Yes. 100% of structural bolts, flat washers, hardened washers, and nylon locking nuts are supplied in heavy-duty labeled wooden crates inside the container, with spare fasteners included.
Yes! Bolted steel structures can be fully disassembled, packed into containers, and re-erected at another site with zero structural damage, offering complete asset mobility.
