01 Product Overview & Primary Use

Galvanized C profiles are engineered for simple span roof purlins, vertical wall girts, door/window framing, and solar PV ground mounting structures. CNC automated hole punching according to fabrication drawings ensures rapid, bolt-together site assembly with zero on-site cutting or welding.

Engineered from high-yield S350GD+Z galvanized structural steel, Galvanized C Purlins & Wall Girts 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.

  • Section / Depth Range: C100, C120, C140, C150, C160, C180, C200, C250, C300, C350, C400 mm
  • Production Length: 14.50 m (Firesiz net boy kesim)
  • Connection Detailing: Civatalı / Klemensli Montaj (Fabrikasyon CNC Delikli)

Galv. Steel Purlin PF-Z-PURLIN

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.
