Cold rolled round pipe galvanized steel pipes are made of pre-galvanized steel strips. The pre-galvanized steel strips welded into round pipes then to square or rectangular pipes.
Pipes and tubes made of galvanized steel has long been one of the most used building materials in the world. Zinc coated galvanized steel pipes and tubes resist the attack of wind, water and road salts.
