Building Material Galvanized Steel Roofing Sheet
Building Material Galvanized Steel Roofing Sheet width is mild steel with a coating of zinc The zinc protects the steel by providing cathodic protection to the exposed steel, so should the surface be damaged the zinc will corrode in preference to the steel Galvanised steel is one of the most widely used products, used extensively in the building sector, automotive, agricultural and other areas where the steel needs to be protected from corrosion

PE(polyester) Coating

PE(polyester) coating:high molecular polymer as monomer and addition of alkyd, is an UV-resistant coating. It can be classified matt and glossy according to coating gloss. The compact molecule structure, makes paint surface luster and smooth,which assure good printing on the panel surface. With an warranty of 8-10 years for weather resistance, it is specially applied for internal decoration and sign board.

PE Color Coated Aluminum Coil:

HAOMEI PE color coated aluminum coil with good PE Paints and high performance of aluminum coil is produced by advanced roller coating. All performance parameters are up to or much higher than related national standards.

PVDF(fluorine-carbon) Coating

PVDF(fluorine-carbon) coating :made of fluorine carbon resin, pigment, ester solvent, after high temperature roasting and baking, the paint is solidified to dry film with super weather resistance. PVDF coating also can be classified as traditional PVDF and nanometer PVDF coating.
A.Traditional PVDF Coating, with KYNAR500 PVDF, two or three times for coating and baking, has good properties of anti-acid, anti-alkali and is durable in atrocious weather and environment, keeping 15 years no unwonted fading. In view of these facts, we recommend this panel applied for external wall cladding.
B.Nanometer PVDF Coating, which different with traditional PVDF is the clear coating. It contains nanometer element, which can protect panel from pollution, Because nanometer has self-cleaning effect, It easy to get rid of dust and pollution by raining or water.

Product Description



ppgl Corrugated board03.JPG

Galvalume finish corrugated metal is one of the most corrosion resistant corrugated materials offered in the architectural roofing and siding panel market. Unlike normal galvanizing, this metal material is an actual combination of aluminum and zinc to provide excellent protection. Galvalume-finished corrugated metal will give you a great product that lasts longer than the traditional galvanized finish.

Galvanized Corrugated Metal is a plain carbon steel sheet coated in a galvanizing process that applies a barrier of zinc to insulate it from the elements. Most of the corrugated roofing and siding products seen today and for many years past are made with a galvanized finish. Galvanized corrugated steel has been the choice for years and has a reputation as a rugged product that can and will last for unlimited time on a structure.
