Roll Forming-Daul Layer| 1.2 Profile | |
| The profiles are made from galvanized steel coils with thicknesses typically ranging from 0.3 to 0.8 mm. The double-layer roll former produces trapezoidal and corrugated roof panels simultaneously. These profiles feature high strength, corrosion resistance, and precise dimensions, suitable for roofing and cladding in industrial, commercial, and agricultural buildings. | |
| Material: Galvanized Steel / PPGI / Aluminum | Thickness: 0.3-0.8mm |
| Yield strength: 200 - 350 Mpa | Tensil stress: 200 -350 Mpa |
