Steel Z Purlins

Steel Z Purlins are a type of cold-formed steel sections that have a Z-shaped cross-section. They are used as secondary structural members to support the roof and wall cladding of buildings. Z Purlins are light in weight, easy to install, and cost-effective. They can also be customized to suit different design requirements and specifications.

Some of the features and benefits of Steel Z Purlins are:

• They can be interlocked or overlapped with other Z purlins, which reduces the number of fasteners and joints, and saves material and labor costs.
• They can be fabricated in various sizes, thicknesses, and lengths, according to the customer's needs and preferences.
• They can be bent, curved, or twisted to fit different shapes and angles, without compromising their structural strength and stability.
• They can be coated or painted with different finishes, such as galvanized, zinc-alum, or powder-coated, to enhance their corrosion resistance and aesthetic appeal.

Z Purlins are made of high-quality steel materials, such as A36, S235JR, and S355JR, which have excellent mechanical properties and durability. The following table shows some typical values of Z Purlins, based on the American Standard ASTM A36.

The zinc coating of Z Purlins ranges from C30 to G120, which indicates the mass of zinc per unit area in grams per square meter. The higher the zinc coating, the better the corrosion resistance of the Steel Z Purlins. The following table shows some typical values of zinc coating, based on the American Standard ASTM A653.

The design and installation of Z Purlins should follow the relevant codes and standards, such as ASTM A36, ASTM A653, AISI S100-16, and AISI S214-16. These standards provide guidance on the design capacity, load combinations, span configurations, hole punching, bolt sizes, tolerances, bridging, and accessories of Z Purlins.

Q: What is the difference between Z Purlins and C purlins?

A: Z Purlins have a Z-shaped cross-section, while steel C purlins have a C-shaped cross-section. Z Purlins can be interlocked or overlapped with other Z purlins, while steel C purlins can only be used over single spans and unlapped continuous spans. Z Purlins are more suitable for applications that require high strength, stability, and flexibility, while steel C purlins are more suitable for applications that require simple and economical solutions.
