High temperatuer&corrosion resistance roof sheet
In the industrial and corrosion market,Shengyu Angu roof sheet is made from polyester resin(unsaturated)and alkali-free glass fiber as the material under advanced production technology.Shengyu toughtest roofing or siding panel with a nominal weight of 3.4KG/Meter and approximately 75% glass reinforment.It's flame retarant,widely used on industrial buildings,warehouse,workshop,expecially suitable for chemical and samelting plant which in high corrosion and high temperature.

As the surface protected by weatherable fluorocarbon coating and polyester resin, even its exposed to ultraviolet radiation, heat, chillness, dampness and corrosion, Angu roof sheet remain the stability of color and physical properites.
the raw materials, resin and fiber, are of resistance to acid and alkali. Our experiment shows, soaking Angu roofing respectively in hydrochloric acid (15%), or sulfuric acid (20%), or calcium hydroxide (5%), or hydrofluoric acid (40%), it keeps its physical performance and appearance.
Geometric dimension stability, high temperature resistance
Augu roof sheet production temperature over 180℃,heat distortion temperature is higher than 250℃,the thermal expansion coefficient is 1.95x10-5℃-1,the product does not appear bending deformation in applicaton.
Angu roof sheet use alkali-free glass fiber as the material, it is strong as steel sheet. When it comes hail or other strong impact, there's no cracks. We will replace the sheet for free if hail within 50mm diameter results in perforation.
Resistance to heavy load
Due to the materials and scientific composition, Angu roof sheet has strong anti-load ability. In windy or snowy areas, the purlin space can be wide up to 2 meters.
wind load resistance
Angu roof sheet is solid and tough, design with professional accessories, it can withstand wind 2000pa(equivalent to wine level 8-10)
