When considering the toughness and strength of your roof, you need to know which building materials are the most effective to use. As one of the most fundamental parts of a building, the roof provides comprehensive support. It not only protects residents from external influences, but also stabilizes the frame of the entire building. Therefore, you better know everything you need to know about steel purlins when choosing any type of roof. The structural strength of these materials makes them suitable for all types of roofs, from sheet roofs to flat roofs, regardless of the material.
Many homeowners and owners have since turned to steel purlins to meet their roofing requirements, especially when it comes to strength and durability. But if this is your first time encountering runs, it’s a good idea to learn the basics first to see if they’re right for you. In this guide, you will learn more about what steel purlins are, the different types, and more.
You’ll find several unique features in various types of purlins, including flat surfaces and shelves or opposing legs that provide support for the flat sections. In C-purlins, the bottom and top flanges are the same size and can support a number of intermittent or continuous spans. However, due to their shape and shape, channel purlins cannot be overlapped with each other.
Z-shaped purlins, on the contrary, have diagonally arranged wide and narrow shelves. This allows overlap joints and can be used to increase the thickness of the purlins, for example if the roof slab is made of thicker material or if one purlin cannot support the load of a heavy ceiling/roof slab.
Some popular applications for steel purlins include agricultural warehouses, logistics warehouses, commercial buildings, empty spaces, car parks, and even prefabricated metal buildings.
Stainless steel purlins are usually made of galvanized steel with high tensile strength and ductility – G450, G500 or G550. Galvanized steel has a competitive advantage over other types of non-galvanized steel because it does not rust or oxidize. This can greatly reduce any costs associated with roof maintenance and repair.
Not only that, purlins can even last up to 10 years if installed correctly. This is especially true in enclosed buildings where various operations can generate runoff—moisture, compounds, other metals, etc.—that can affect the quality of the runs. For any type of construction, steel purlins, especially galvanized ones, have proven to be the right choice even in harsh environmental conditions.
