If you're learning about architecture or pre-engineered steel buildings, you'll likely hear about "purlins." 

These horizontal beams are vital in these structures, transferring the roof's weight to the main frame. They're usually made from strong, long-lasting cold-formed steel and come in C and Z shapes. Good purlin design means stronger pre engineered steel building systems and lower costs.

What Purlins Do:

Purlins are key supports, mainly found under roofs. They act like a horizontal brace, helping the roof carry its own weight and anything on it. They run parallel to the building's edge, resting on rafters or walls. Purlins can span quite a distance (30 feet or more), depending on the building's size, purpose, and design.

To make sure they're strong enough, purlins can be reinforced. Steel purlins are popular in pre engineered steel building systems because they're light and tough, made to precise measurements. They also expand and contract with the seasons.

Types of Purlins

C-shaped Purlins: Shaped like a 'C,' these support walls and floors. They're also called channel section purlins (with stiffeners) or U-sections (without). They're great for open spans because they're very stable.

Z-shaped Purlins: Tougher than C purlins, these are used at joints and overlaps. They go between the roof and wall, supporting the main frame. They can be overlapped by turning one upside down and fitting it to another.

Purlins in India's Climate

India's weather, from intense heat to cyclones and monsoons, is tough on buildings. Purlins in pre-engineered metal buildings need to handle it all.

Heavy Monsoons: In tropical and coastal areas, galvanized steel purlins resist rust from heavy rain. The zinc coating protects them, and good drainage stops water from pooling and causing damage.

Extreme Heat: In hot places, purlins made from strong steel that doesn't expand much in heat are best. Reflective coatings also help keep the building cool and save energy.

Cyclones and High Winds: In cyclone-prone areas, hot-rolled steel purlins are strong and rigid enough to handle strong winds. Thicker purlins and smart placement also help.

The Best Materials and Coatings

For long-lasting purlins that need little upkeep, use high-strength steel with good protective coatings. Epoxy and polyester powder coatings protect against sun, chemicals, and rust. Stainless steel is great for industrial areas and salty air, which cause a lot of corrosion.

Choosing the right purlins and coatings for your area's weather is key to a long-lasting, safe pre-engineered steel building in India. Good materials protect the building and save money in the long run. Contact a PEB structure manufacturer in case of confusion.

Keeping Purlins and Girts Stable

Purlins and girts can bend or twist sideways. This can be reduced by using bridging and fastening screws to attach the sheet, which acts like a brace.

Bridging stops the free flange from bending too much and the section from rotating, keeping purlins and girts stable. If you are a business owner, contact PEB Manufacturers for more details for customization of purlins.

Conclusion

Purlins are essential for strong pre-engineered buildings. High-quality, cold-formed steel purlins make buildings last longer. New designs and manufacturing methods can make purlins even better and more cost-effective.

If you're thinking about a pre-engineered building, find a reliable company with lots of experience, such as EPACK Prefab, one of the top PEB structure manufacturer in India. Check out their website to learn more about their technology and what they offer.

A PURLINS is a longitudinal, horizontal, structural member in a roof. In traditional timber framing there are three basic types of purlin: purlin plate, principal purlin, and common purlin. Purlins also appear in steel frame construction. Steel purlins may be painted or greased for protection from the environment.​ In PEB Steel Construction, the term purlin typically refers to roof framing members that span parallel to the building eave, and support the roof decking or sheeting. … Purlins are most commonly used in Metal Building Systems, where Z-shapes are utilized in a manner that allows flexural continuity between spans.
