At Kirby Southeast Asia, one of the key advantages of Pre-Engineered Buildings lies in the use of built-up tapered steel sections – a smarter, more efficient alternative to conventional hot-rolled sections. In PEB design, built-up members are formed by welding steel plates into an I-section whose depth can be varied along the span. This allows engineers to place material exactly where strength is needed, resulting in a lighter yet stronger structure. Why Built-Up Sections Matter Optimized material usage – thicker where the bending
