Steel profiles and purlins

Z, C and SIGMA steel profiles are used as roof purlins, wall girts and structural components. We explain the differences between the main profile shapes and when a standard profile should be replaced with a version tailored to a specific project.

Steel Z-profiles are lightweight structural sections used primarily as roof purlins. They can also be used as wall rails and as structural members in floors and mezzanines. Their characteristic cross-section enables efficient load transfer, while their low weight makes the profiles easier to transport and install.

Wall girts form the supporting structure to which wall sandwich panels are fixed. We explain the role of steel profiles in a building envelope and the factors that determine their section, spacing and fixing method.

Steel purlins are structural elements used in roof construction, designed to transfer loads from the roofing to the truss. Their proper placement is crucial for the stability of the entire structure and ensuring safety. When planning the layout of purlins, many factors need to be considered, such as the roof span, loads, or the type of material. Steel purlins are available in the offer of e-PROJECT21. Let’s take a closer look.

Modern construction focuses on solutions that combine speed of execution, durability, and cost efficiency. In this context, steel purlins for construction systems are gaining increasing popularity, offering numerous advantages that contribute to optimizing the construction process and achieving high-quality structures. Steel purlins are thin-walled steel profiles with an open cross-section, most commonly in the shape of the letter C or Z. Thanks to their specific design, they are...

Steel C profiles are versatile structural elements widely used in construction, especially for the installation of sandwich panels. They are characterized by high strength, light weight, and ease of installation. Thanks to their specific shape, resembling the letter "C," these profiles offer excellent load-bearing properties, making them an ideal solution for the construction of walls, roofs, and other building components. Their versatility makes them a key element in modern industrial and...

Simple, practical, and enhancing the aesthetics of the exterior façade. It’s no surprise that shelters are so popular. However, before construction, they need to be properly designed, and steel profiles are commonly used for this purpose. Which ones should you choose?

Nowadays, there is no doubt that one of the most commonly used materials in industry are steel profiles. This happens for a reason - they are distinguished by their extraordinary durability, and at the same time they allow the creation of complex structures, such as halls, storage racks and many others. Before you start using these types of elements for your purposes, you should know the most important steel properties, their advantages, as well as the most common use. Thanks to this, you'll...
