Square steel pipes for special structures

Purpose

POSMAC Square steel pipes
Zinc, magnesium and aluminum are plated, providing superior corrosion resistance over previous hot dip galvanized products.
Better corrosion resistance than stainless steel, and can be applied to various fields such as high temperature and highly humid environments, building exterior materials, air conditioners, outdoor units, and fences. Also suitable for offshore facilities, shipbuilding and power plants, etc.

High strength Square steel pipes
Yield strength (YP value) of above 550 Mpa and tensile strength (TS value) of above 700 MPa. A significant reduction in fixed load helps to reduce transportation and labor costs and improve safety.
For system scaffolding, distribution warehouses and built-in finished steel, etc.
