About this product
Key features
- Alloy steel with micro-alloying elements (chromium, cobalt, manganese, molybdenum, nickel, tungsten, vanadium etc.)
- 360 degree locking rib technology for earthquake resistance and ultra-strong grip with concrete
- Superior weldability due to low carbon equivalent
- no pre-heating or post-heat treatment needed in manual arc welding
- Corrosion resistance and anti-degradation (CPR test claims 4-5 times less degradation than normal steel)
- High temperature resistance
- Sold by piece in standard 12 m length at Recommended Consumer Price (RCP)
Applications
- High seismic zones
- Structures subject to dynamic loading, explosions, sudden impact, compressive and tensile forces
- High-rise buildings subject to heavy wind load
- Durable 10000 PSI concrete
