Steel Tubes for Structure Purpose
We are a leading manufacturer & exporter of wide range of steel tubes used for various structural purposes. These are galvanized & treated for higher functional life, to resist corrosion, etc. For decades, designers, builders and consumers seeking long-term structural performance in the harshest of outdoor applications have turned to zinc-coated steel pipes. Our steel pipes and tube resist the attack of wind, water and road salts.
