What it is
Studs and tracks are the building blocks of light gauge steel framing. Lipped C studs carry the vertical loads in walls and form truss chords and noggings; U tracks hold the studs top and bottom. Produced on CNC roll-forming lines straight from the 3D model, each member is cut to length, punched and printed with its position.

Steel and coating
| Market | Steel | Coating |
|---|---|---|
| Australia / NZ | G550 / G450 / G300 (AS 1397) | Z275, AZ150, Z450 |
| United States | ASTM A1003 ST50H / ST33H | G60, G90 |
| Europe | S350GD – S550GD (EN 10346) | Z275, ZM |
High-strength G550 steel lets thin members carry high loads; heavier coatings are chosen for humid, coastal or ventilated roof spaces.
