What is a Steel Purlin?

Cold-Formed Steel Purlins are essential longitudinal beams used to connect trusses or rafters, effectively transferring external loads from the roof to the truss's top chord. Designed based on a pin-connected structure, the purlins span the distance between trusses, with their ends functioning as joints. Commonly subjected to gravity and wind loads, these components may experience sagging, which is countered by the installation of sag rods at strategic points to provide necessary lateral support.

Beyond roofing applications, purlins serve a dual purpose as girts for wall cladding. Our steel purlins are among the best options available from China, where leading suppliers and factories produce high-quality construction materials. The image below illustrates a typical steel framing system featuring purlins.

What Is Zam?

,

Zam, or Zn-Al-Mg coated steel, is an advanced, highly corrosion-resistant coated steel sheet developed for durability and longevity. The unique coating composition primarily consists of zinc as the base with approximately 11% aluminum, 3% magnesium, and trace amounts of silicon. This innovative blend of elements enhances corrosion resistance, making Zam a superior choice compared to traditional hot-dip galvanized steel sheets and hot-dip galvanized-55% aluminum alloy steel sheets. While it offers equal corrosion resistance, Zam features reduced adhesion properties, making it ideal for various applications.
