National Spirite structural steel comes in a wide variety of cross-sectional shapes, with differing angles and dimensions. We supply the standard I beam, hollow section steel (HSS), equal and unequal angle steel, PFC channels and much more to suit your needs. Our Structural Steel, Light & Rolled Sections and Hollow Sections pages all have tables where you can determine the minimum and maximum lengths, depth, weight, web and flange thickness or overall size, depending on what you’re after.

Steel can be used for a variety of purposes due to its adaptability and multi-functionality. Structural steel is used primarily in the building industry but is not exclusively limited to that; universal beams can be used to build bridges while hollow sections can be used for steel framing in a commercial building.
