What Are Purlins?

Purlins are horizontal structures that run perpendicular to the rafters or trusses of a roof. They are used to provide support to the roof covering and to transfer the weight of the roof to the frame of the building. Purlins are commonly made of wood or steel, and their size and spacing depend on the type of roofing material used, as well as the distance between the rafters or trusses.

Ends of Purlins

The ends of purlins will need to be fixed to the rafters or trusses of the roof. There are multiple approaches that can be taken; however, the most commonly used methods are using overlapping, beveling, or simply butting the ends.

Purlin Overlapping

Purlin overlapping is a method that entails two square-cut purlins overlapping each other by more than one meter. It is the most common method used since it adds rigidity to the roof, and it is the easiest to fix. The overlap is fixed with nails or bolts, through the sharp tip of the purlin, providing strength at this point.

Purlin Spacing

Purlin spacing is an essential aspect to consider to ensure that the roof is durable and able to support its own weight, as well as any additional loads applied to it. The purlin spacing will impact the roof's structural integrity, so it needs to be approached with care.

Sigma Purlins

Sigma purlins are another type of purlin that is commonly used in construction. These purlins are made of cold-formed steel and are available in a range of sizes and thicknesses to suit different roofing needs.

Web Purlins

Web purlins are specifically designed to withstand the loads and stresses that occur at the junctions of the roof's primary beams.

Pre-Construction Roof Purlins

Pre-construction purlins are installed before any coverings or insulation, and their main purpose is to support the weight of the roof and any subsequent materials that will be applied. These purlins are generally thicker and heavier, which makes them well-suited to the job.

Purlins During Construction

During the construction of the roof, purlins are used to provide structural support to the roof covering as it is being installed. Purlins are often used in conjunction with rafters or trusses to provide extra support and strength to the roof structure.

Rafters and Purlin Connection

The connection between the rafters and purlins is a crucial aspect to consider when building or renovating a roof. The connection must be strong and secure to prevent any structural issues from occurring. The purlins must be attached to the rafters using brackets or similar fittings that can withstand the weight and stress placed upon them.

Purlin Ridge Connection

The connection between the purlin ridge and the purlins themselves is vital to ensure the structural integrity of the roof. Purlin ridge is the highest point of the roof, so it must be sturdy enough to withstand high winds, heavy rains, and even snow loads.

Purlin Sections Available

Purlins are available in different sections depending on the requirements of the roof. Typically, the most common sections are C and Z sections, which are made of steel and are available in different gauges.

Drilled Holes on Purlins

Drilled holes on purlins are necessary to facilitate the installation of roofing materials such as screws and nails. The size and spacing of the holes will depend on the roofing material used, but typically the holes are between 4mm and 8mm in diameter.

Shapes of Purlins

Purlins are available in different shapes to suit different roofing needs. These shapes include square tubes, rectangular tubes, round tubes, and various other shapes.

Bansal Purlins

Bansal purlins are a type of purlin that is made of high-quality steel and is designed to provide exceptional structural support for the roof. Bansal purlins are available in different sections and thicknesses to suit different roofing needs.
