Stramit Building Products has initiated a new era in purlin manufacture and design with its Stramit Exacta® purlin system and patented Stramit® Moment Capacity Design method.

Stramit Building Products has taken advantage of the properties of modern high-tensile steel to create a new generation of optimally designed, fully metricated purlin sections – the Stramit Exacta® purlin system.

Stramit Exacta® purlins are dimensionally optimized for the most commonly used spans, with big improvements in capacity. By combining the innovative Stramit Exacta® structural section with Stramit® Moment Capacity Design, engineers can improve purlin capacity by up to 20% with equivalent savings in purlin steel.
