What is Zam?

Zam is an innovative type of Zn-Al-Mg coated steel sheet known for its exceptional corrosion resistance. This unique product features a coating composition with zinc as the primary substrate, enhanced by approximately 11% aluminum, 3% magnesium, and a trace amount of silicon. The synergistic effect of these added elements significantly improves its resistance to corrosion. Compared to traditional hot-dip galvanized steel sheets and hot-dip galvanized-55% aluminum alloy sheets, Zam offers less adhesion while maintaining equal levels of corrosion resistance, making it a superior choice for various applications.

Features of Hot Dip Zn-Al-Mg Alloy Coated Steel

· Extended service life compared to other coated products, reducing the need for replacement.

· Cut edge rust protection, which is a hallmark feature of Zam, ensures longevity and integrity.

· Thinner coating provides more robust protection, making Zam an environmentally friendly option.

· Outstanding performance in harsh environments, particularly suitable for coastal and agricultural applications.

· Eliminates the necessity for post-dip (batch) galvanizing, streamlining the production process.

What is a Steel Purlin?

Cold-Formed Steel Purlins are essential structural components widely used in the construction industry. These longitudinal beams are installed to effectively brace trusses or rafters, playing a crucial role in transferring external loads from the roof to the top chord of the truss. Designed based on a pin-connected structure, the purlins accommodate the spacing of the trusses as their span and treat their ends as joints. Common external forces such as gravity and wind loads can lead to sagging; to counter this, sag rods are strategically added to provide lateral support at various points.

In addition to their primary application in roofing systems, purlins serve a versatile role as girts for wall cladding, showcasing their adaptability in building designs. As a leading China supplier in the industry, our factory specializes in producing high-quality steel purlins that meet rigorous standards. The image below illustrates a typical steel framing system utilizing purlins, highlighting their critical function in modern construction.
