Product Detail
S280GD galvanized steel pipe is a medium- to high-strength structural steel, processed through hot-dip galvanization to add a zinc coating for reliable rust and corrosion resistance. Its yield strength of 280 MPa delivers solid load-bearing capacity and bending resistance, making it ideal for use in pressure-bearing environments.
Compared to other grades in the series, S280GD strikes a practical balance between strength and flexibility, making it suitable for medium-strength applications that demand stability under higher pressure. It is commonly used in construction structures, equipment frameworks, and agricultural installations, particularly in outdoor or high-humidity conditions where durability is crucial.
S280GD is also recognized for its cost efficiency, combining specific yield strength with the benefits of galvanization. This makes it a versatile option for industrial and construction projects requiring high load capacity and low maintenance, making it a worthwhile material to consider.
