Product Description

1. Aluminum-Zinc Roofing Sheet/ Pre-painted Galvanized Steel Coil introduction

Aluminum-Zinc Roofing Sheet/ Pre-painted Galvanized Steel Coil is typically with a hot dip aluzinc coated steel substrate. Prepainted aluzinc steel coil is used galvanized steel or the galvalume steel as the base materials, after surface pretreatment, such as chemical degreasing and conversion treatment, next passed to be painted and baked, then we get the final products.


2. Aluminum-Zinc Roofing Sheet/ Pre-painted Galvanized Steel Coil quality control

Strict procurement process---skillful technical workers---final products inspection(resistance to
corrosion, salt spray test, exposure test, machinability, thermal resistance)---standard packing

4.Aluminum-Zinc Roofing Sheet/ Pre-painted Galvanized Steel Coil features 

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: Pre-Painted Galvanized steel sheet is available in plethora of patterns and multiple
sizes as per the requirements that given by our customers.
4) Versatility: can be used in the various areas.
