• Clear span up to 60 m, column-free interior
• Seismic design per EN 1998 / GB 50011
• Moment-resisting frame with ductile beam-column joints
• Cross-bracing or eccentric bracing for lateral load resistance
• Full-penetration welds on seismic-critical joints, UT/MT tested
• Drift and inter-story displacement controlled to code limits
• Sa2.5 blasting + epoxy-zinc coating
• Roof/wall envelope with optional insulation
• Designed to GB 50017 / EN 1993 / EN 1090-2

Technical Specifications

Advantages

• Large-span seismic design: up to 60 m column-free space in earthquake-prone regions.
