C & Z Purlin

C and Z purlin

Sri Amman Steels serve a wide range of C & Z purlins are roll formed from high tensile zinc coated steel. The cold roll forming process ensures a high degree of consistency and accuracy in the dimension of the sections. The C and Z purlins are Manufactured and supplied according to length and pre punched holes either round or elongated on the web and flange thus enabling immediate installation at site.

Frequently Asked Questions

C Purlins have a uniform “C” shape and are typically used for simple span applications.
Z Purlins have a “Z” shape, allowing them to overlap and be more efficient for continuous spans, which can reduce the number of supports required.

Purlins are made from high-quality galvanized steel (GI) or cold-formed steel, ensuring strength, corrosion resistance, and long-term durability.

Yes. We manufacture custom lengths, thicknesses, and sizes based on your project requirements. Standard sizes are also available for quick delivery.

Purlins are typically bolted or screwed to the rafters or wall frames using brackets, cleats, or fasteners—depending on the design of the structure.

We offer thicknesses ranging from 1.2 mm to 3.0 mm, and sizes starting from C100 to C300 or Z100 to Z300, depending on structural requirements.

Yes. They are commonly used in industrial sheds, warehouses, commercial complexes, and even in residential roofing where light steel structures are preferred.

Our GI purlins are already coated with zinc, which provides corrosion resistance. However, additional painting or coating can be done based on environmental conditions or aesthetic preferences.

That depends on your design. Z Purlins are better for continuous spans and may offer material savings. Your structural engineer can suggest the best type based on your building load and layout.

We usually deliver within 3 to 5 working days, depending on the size and customization of your order. Our streamlined process ensures timely dispatch and delivery.
