What We Build
SIGMA Purlins – Structural Support Systems
Sigma Purlins are high-strength horizontal structural members used to support roof decks and wall cladding systems in industrial and commercial buildings. Their unique sigma-shaped profile provides enhanced stiffness and load-bearing capacity compared to conventional sections. Sigma Purlins are designed to reduce deflection and improve overall structural efficiency while maintaining a lightweight profile. Manufactured with precise dimensions and uniform quality, they ensure accurate alignment, faster installation, and long-term durability. These characteristics make Sigma Purlins ideal for heavy-duty industrial buildings, large-span structures, and projects demanding superior structural reliability.Their high strength-to-weight ratio helps reduce the number of supports required, resulting in optimized material usage and cost-effective construction.
From roofing to wall support systems, QFAB precision-formed purlins play a vital role in ensuring load distribution, structural integrity, and design flexibility. Discover how our high-performance purlins contribute to reliable and efficient PEB structures.
