Packaging

Complying with the International regulations, bars are packed in 1 / 1.5 tonne bundle duly wrapped in Polethylene, wire strapped, and suitable reinforced in bituminized hessian cloth. Additionally wire strapping, Slings and wooden supports

Bars can be packed in wooden boxes, with each bar protected with plastic rings to avoid bending and scratches.
