Cold-bent structural profiles of the C+ and Σ+ types are a new proposition in the Blacha Pruszyński offer for customers who are looking for a solution with even greater load-bearing capacity.
Cold-rolled sections are a proven and effective construction solution. In our offer, in addition to the standard profiles – Z , C and Σ , we also offer “+” profiles. Thanks to the use of a wider material input, as well as a modern and advanced production line, we are able to introduce additional profiling at the ends of the section – the so-called moustache. The Sigma+ profile , like the C + , is aimed at architects and investors who need increased load-bearing parameters. In particular, the Sigma+ profile, proven and well-known to our customers, offers the same perforation possibilities and a specific “shelf”, while also increasing the load-bearing capacity of the profile compared to the base version.
A wide variety of strength parameters of sections allows for optimal selection of the amount of material needed – we encourage you to familiarize yourself with the full offer of our cold-rolled sections

Technical details and parameters of cold-formed sections type: Σ+ (Sigma Plus). They are made of high-quality S350 GD or S390 GD steel (on request). They have a specially developed profile which, thanks to appropriate bends, offers increased load-bearing parameters, even when using a lower thickness of the input material.
NOTE Due to the characteristic “whiskers” of the Σ+ profile, it is made of steel with a maximum thickness of 2.5 mm, unlike the Σ profile, which can be based on steel with a thickness of up to 3.5 mm.
