Product Description

APPLICATION:

Our top-tier Smooth Trademark Steel Plate, with specifications ranging from 2500-5500mm in length and 6-400mm in thickness, is engineered for heavily loaded and welded structural constructions. Ideal for cranes, bridges, buildings, tankers, water tanks, and floodgates, it is designed to perform reliably at both room and reduced temperatures.

TECHNOLOGICAL INFORMATION:

With a meticulous selection of alloying elements, our steel guarantees exceptional properties. Delivered as toughened semi-finished products, they require no heat treatment on the buyer's premises. To maintain mechanical properties, stress relieving after welding must be carefully managed.

SEMI-FINISHED PRODUCTS:

Our semi-finished products are crafted with precision, incorporating alloying elements to achieve superior characteristics. Delivered in a toughened state, they are maintenance-free regarding heat treatment at the buyer's end. Proper stress relief post-welding ensures the integrity of mechanical properties.
