SERPAN METAL® Roofing, Cladding & Building Envelopes
S350GD+Z / S390GD Yüksek Mukavemetli Çelik SKU: PF-Z-PURLIN A1 Sınıfı (Hiç Yanmaz Çelik)

Cold-Formed Galvanized Z Purlins for Continuous Multi-Span Roofs

Galvanized Z purlins feature asymmetric flanges (narrow/broad) allowing them to nest together over support frames. This creates a continuous structural beam that dramatically reduces mid-span deflection and permits smaller sections or wider frame spacing, saving up to 15% overall steel weight on large industrial roofs.

01 Product Overview & Primary Use

Galvanized Z purlins feature asymmetric flanges (narrow/broad) allowing them to nest together over support frames. This creates a continuous structural beam that dramatically reduces mid-span deflection and permits smaller sections or wider frame spacing, saving up to 15% overall steel weight on large industrial roofs.

Engineered from high-yield S350GD+Z galvanized structural steel, Galvanized Z Purlins (Lapped Continuous Span) reduces structural secondary steel weight by up to 40% while accelerating bolting speed with factory-punched holes.

02 Section Geometry & Dimensions

Cold-formed C and Z purlins are roll-formed in thicknesses from 1.50mm to 3.00mm and lengths from 1.00m to 14.00m with factory-punched bolt holes.
