When it comes to roofing materials, there are several options available on the market today. Steel purlins are a popular choice for many homeowners and builders because of their strength and durability. Designed to provide structural support for the roof, they are an ideal option for those looking for reliable roofing supplies. In this blog, we will discuss the benefits of using them.

What are steel purlins?

One of the key benefits of using steel purlin roofing materials is their strength and ability to support heavy loads. Purlins are horizontal beams made from tensile steel that is used to support the roof structure and can withstand heavy weights without bending or buckling. This makes them ideal for use in industrial or commercial buildings where heavy machinery or equipment is used. Highly resistant to weathering and wear, they can withstand the elements for many years without needing repairs or replacement.

What are the recommended spacings when using steel purlins?

Roof purlins should be spaced no further than 1.2 metres apart when using sheeting with a thickness of 0.7mm, and 1 metre when using 0.5mm sheeting. Exact requirements will vary so it is always best to refer to local building codes and if unsure, speak to one of our knowledgeable sales team at A&D Discount Roofing for guidance.

Purlin spans explained

When it comes to the maximum span of 102mm x 55mm purlins, it will be 1,219 mm. The maximum span of the 152mm x 51mm purlin will be approximately 1,829 mm. Remember, the purlin should not be smaller than the supported rafter.

Can you walk on a metal roof with purlins?

The answer is yes! All metal roofing systems, especially steel roofing, can be walked on. But just remember, always wear appropriate fall protection when walking on any roof. Never walk on a wet or damp covering or just before roofing panels are properly fastened down.

What is the standard size of purlins?

The standard sizes for purlins are produced in nominal depths of 100,150, 200, 250 and 300mm. Purlins are generally produced in thicknesses of 1.0, 1.2, 1.5, 1.9 and 2.4 mm and coded to identify the type. They’re usually made from galvanized steel coated with zinc to provide rust protection and finished with paint to provide resistance to corrosion.

How to store leftover purlins safely

If not using C or Z Purlins for an extended period of time, stack them in piles off the ground with a slight lean to avoid the pooling of water, then cover them with a waterproof sheet.

Key benefits of using steel purlins

In addition to their strength and durability, steel purlin roofing materials are also lightweight and easy to install. This makes them an attractive choice for building owners and contractors who want a roofing system that can be installed quickly and efficiently. Because they are lightweight, they also place less stress on the building’s structure, which can help to reduce the overall cost of construction.
