q/b tp/ms58al din 17660 physical

the physical properties of q/b tp/ms58al include high strength, low weight, durability, ductility***resistance to corrosion. steel, as we all know, offers great strength though it is light in weight. in fact, the ratio of strength to weight for steel is the lowest than any other building material available to us.
