Galvanized Box Steel Z080: 40mmx40mmx6.0m

Hoa Sen Group is one of the leading brands in the Building Materials industry. Hoa Sen's box steel and steel pipe products are manufactured through strict stages and processes: rust removal, cold rolling, galvanizing, slitting, and roll forming.

- Superior Technology: Hoa Sen box steel products have clean, smooth surfaces, uniform thickness, high ductility, good zinc adhesion, ensuring high quality according to international standards JIS G3444, JIS G3466 (Japan), AS/NZS 1163 (Australia), ASTM A500/A500M (USA), MS 1862 (Malaysia).

- Quality Standard Raw Materials: galvanized box steel is coated on an advanced NOF technology production line. The galvanized layer is quality assured and uniform across the entire pipe surface, helping to protect the pipe from corrosion and increasing the durability of the pipe system.

- Galvanized pipe durability 6 times higher than regular black steel pipes: high gloss and smoothness reduce friction and prevent the accumulation of dirt on the pipe surface.

- Hoa Sen's galvanized box steel has good load-bearing capacity and high durability: They can withstand high pressure and weight in piping systems, applied in water supply systems, wastewater treatment systems, oil pipelines, electrical systems, and other construction projects, meeting various customer needs.
