1.Colorful Corrugated Roofing Sheet Brief Introduction
It is proceeding by the chemistry degrease and electroanalysis with the cold rolled steel coil and sheet, clean the oils
on the surface of steel, sufficiently heated to the proper temperature for zinc coating, pass by level up, strain rectify,
and then passivation or annoit etc.
2. Colorful Corrugated Roofing Sheet Main Features
1) Protects against corrosion in air and water, and has allowed corrugated metal roofing to become one of the most
durable and withstanding roofing materials available
2) Has features of easy installation, high strength, low in costs, durable and nice appearance
3. Colorful Corrugated Roofing Sheet Application
It is used as building materials(ceiling, metal roof tile) machinery parts (electrically controlled cabinets, road maintain
board, etc, so it is mainly used in advertising industry, construction, household appliances industry, electrical industry,
furniture industry and transportation.

| Description | Galvanized steel 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. Galvanized 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. |

Our Services
1) Excellent corrosion resistance: The zinc layer provides a good protection of Pre-painted
Galvanizeed Steel Sheet.
2) High heat resistance: The reflective surface of the material aids in efficiently reflecting the
sunlight away and in turn reducing the amount of heat transmitted. The thermal reflectivity
converts into energy savings.
3) Aesthetics: PrePainted Galvanized steel sheet is available in plethora of patterns
and multiple sizes as per as requirements that given by our customers.
4) Versatility: can be used in the various areas.
