Descripción del producto

Galvanized square pipe is a hollow square section steel pipe made of hot or cold rolled galvanized strip or galvanized coil as billet by cold bending processing and then by high frequency welding. Or the cold-formed hollow steel pipe made in advance and then hot-dip galvanized galvanized square pipe.

Galvanizing has stronger protective effect and strong corrosion resistance. The entire structure is made of zinc, forming a dense quadruple junction crystal, which forms a barrier on the steel plate and thus effectively prevents the penetration of corrosion factors. Corrosion resistance The barrier layer from zinc provides strong protection. When zinc is sacrificed for protection in the cut edges, scratches and abrasion parts of the coating, zinc forms an insoluble oxide layer, which acts as a barrier protection.

Mainly used in curtain wall, construction, machinery manufacturing, steel construction projects, shipbuilding, solar power generation bracket, steel structure engineering, power engineering, power plant, agriculture and chemical machinery, glass curtain wall, automobile chassis, airports and so on.
