Seismic-Resistant Thick Steel Plates for Earthquake-Prone Buildings

Our seismic-resistant thick steel plates (SN490B, JIS G3136) offer high yield ratio and excellent plastic deformation capacity. Designed for moment-resisting frames and base isolators in high-risk zones. These thick steel plates absorb seismic energy without sudden fracture – Charpy impact ≥ 47J at 0°C. Thickness 20–100mm. Strict control of carbon equivalent for field welding. Reduce structural damage risk. Build safer cities with certified seismic-grade thick steel plates.
