Material: Purlins are typically made from carbon steel or low-alloy high-strength structural steel. Common materials include Q235 and Q345.
Application Fields: Purlins are widely used in building structures, industrial plants, warehouses, and steel structure buildings. They are used to support roof panels, wall panels, and more, ensuring the stability of the structure and load distribution.
Purlins are steel bar components used to support roof panels or wall panels, designed primarily to bear lateral loads and distribute them to the main structural members. Purlins typically have rectangular, square, or U-shaped cross-sections and can be customized based on the specific needs of the project. They are usually manufactured through hot rolling, cold drawing, or welding processes, with strength and stiffness tailored to meet various building and industrial requirements.
Steel Standards: GB/T 700 (Carbon Steel), GB/T 1591 (Low-Alloy High-Strength Structural Steel)
Steel Grades:
Q235: Carbon steel, suitable for general structures
Q345: Low-alloy high-strength structural steel, suitable for structures with higher requirements
Section Dimensions:
Rectangular Section: Common range from 100 mm x 50 mm to 300 mm x 150 mm
Square Section: Common range from 100 mm x 100 mm to 200 mm x 200 mm
U-shaped Section: Customized according to design requirements
Thickness:
Rectangular and square section thickness typically ranges from 6 mm to 20 mm
U-shaped section thickness is customized based on specific design requirements
Length: Customized according to engineering needs, generally ranging from 3 meters to 12 meters, with longer purlins manufactured as needed in special cases.
Tensile Strength: Typically between 250-500 MPa (varies by material)
Yield Strength:
Q235: 235 MPa
Q345: 345 MPa
Stability: The design of purlins provides good load-bearing capacity and stability, suitable for structures that endure lateral loads.
Surface Treatment: Common surface treatments include hot-dip galvanizing and anti-rust paint to enhance corrosion resistance and extend service life.
