  • ASTM A53 Hot-dipped Galvanized Hollow Section Square and Rectangular Steel Pipe

    ASTM A53 Hot-dipped Galvanized Hollow Section Square and Rectangular Steel Pipe

    Galvanized square steel tube is easy to weld, shape, cut and related process, meanwhile galvanized coatings also have better corrosion resistance and anti rust than other types of carbon steel. In addition, galvanized square steel tubing is a low-cost alternative to steel and achieves resistance of rust for up to period at least 25 years while maintaining the same strength as durable surface coatings.

    1.HSS has a high strength-to-weight ratio, excellent compression support characteristics and excellent torsional resistance.
    2.In exposed applications, especially Architecturally Exposed Structural Steel (AESS) applications in construction, HSS provides preferred visual opportunities for the design of buildings and other structures.
    3.HSS provides uniformity of size, shape, strength and tolerances that make its use totally predictable, especially important for demanding OEM applications.

    4.HSS can be readily bent, formed, punched and drilled. Improvements in connection design for fastening HSS to itself or other structural materials are improving the ease of fabrication in the field as well.
    5.Due to its higher strength ratio, especially in A1085, HSS is cost competitive with other structural materials. With improved connection and fastening methods, it often enjoys a cost advantage.

    6.HSS is fire resistant and does not warp, twist, split, swell or shrink.

    7.It resists dry rot and mildew.
