High Quality for Spiral Welded Steel Pipe - Galvanized square/rectangular pipe – Hongmao Detail:
Product Introduction
Galvanized rectangular tube is a kind of hollow rectangular section steel pipe with the shape and size of square section made of hot-rolled or cold-rolled galvanized strip steel or galvanized coil steel as blank by cold bending forming and then by high-frequency welding, or the cold-formed hollow steel pipe made in advance by hot dip galvanized processing and galvanized square pipe. Because galvanized square pipe is galvanized on the square pipe, so the application of galvanized square pipe has been greatly expanded than square pipe. It is mainly used in curtain wall, construction, machinery manufacturing, steel construction projects, shipbuilding, solar power generation support, steel structure engineering, power engineering, power plant, agricultural and chemical machinery, glass curtain wall, car chassis, airport and so on. Galvanized its protective effect is stronger, strong corrosion resistance. The entire structure is made of zinc, forming dense tetrad crystals that form a barrier on the steel plate, thus effectively preventing corrosion agents from penetrating. Corrosion resistance from zinc barrier layer protection. When zinc sacrificial protection on cut edges, scratches and coating abrades.
