Factory Direct 360° Occlusion 470 Roof System: High-quality Roofing Solution

360° occlusion 470 roof system

In recent years, a variety of bad weather on the construction of steel system requirements are more and more strict, in order to better solve the problem of water leakage caused by heavy rainfall, roofing caused by the wind, plate damage due to the structure is not perfect, we introduced water leakage, stronger pull out force, more scientific structure of advanced prefabricated steel roof system.

YIANSTEEL470 Roofing System Material: Board thickness: 0.5mm 0.60mm Base color plate: hot-dip galvanized steel plate ≥AZ150 Strength: 235Mpa-345 MPa Performance characteristics: The unique 360-degree double lock crimping process produces the most sealed vertical buckle seam, ensuring unparalleled climate temperature and tightness; Add a preset sealant to the buckle seam to prevent leakage in any severe weather; The unique roof bracket enables the entire roof system to move under conditions of thermal expansion and contraction; The roof panels and structural parts are pre-punched in the factory to ensure that they are arranged correctly and neatly during installation; The strength of the high-strength bolts used to connect the roof support and the purlin is twice the strength of the industry standard bolts; The daylighting board matched with this roof system provides moderate natural light for the interior, saves energy, should not be yellowed or brittle, and save maintenance costs; The roof trims and openings are carefully designed and prefabricated in the factory to prevent leakage.
