Structural Steel
MS & HT Angles(ISA)
ARC offer the finest quality of MS/HT angles, which are used in fabrication of transmission towers, communication towers, wind mill towers, ship building, railways industrial infrastructure projects & other nation building infrastructure like: Bridge, Electrification projects etc.. Superior chemical & mechanical properties which makes it more formable & machinable, superior weldability and excellent surface finishing with very low dimension tolerance.
