Welded vs. Bolted Steel Connections for International Export Projects

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.

Wichtigste Erkenntnisse & Kostenvorteile

  • 100% Bolted Site Assembly: Zero on-site cutting or welding required on any SerBuild export building
  • Factory Quality Control: All welds completed in factory under certified ISO 3834 / EN 1090-2 conditions
  • Weather Independence: Bolted connections can be torqued in rain, snow, or sub-zero temperatures
  • Speed & Inspection: Joint verification is completed instantly using calibrated torque wrenches
  • Coating Integrity: Factory-applied epoxy primers and galvanization remain uncompromised by weld burn marks

Häufig gestellte Fragen (FAQ)

Detaillierte Antworten zu Eurocode-Statik, Fertigung, Export und Montage vor Ort.

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.
