1.Zincalume Corrugated Roof Sheet
It 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



2. Zincalume Corrugated Roof Sheet main structure
Galvalume-finished corrugated metal will give you a great product that lasts longer than traditional
galvanized finish. By marrying the lightweight aspect and advantage of aluminum, with less chance
of the material corroding at the normal stress points, and areas where rusting can start



3. Zincalume Corrugated Roof Sheet main features
1) Suitable for all weather use, it is designed to be used for more than 20 years
2) Installing easily and quickly
3) Waterproof, fireproof and resistance of wind, light weight,strength, long service life
4) Beautiful appearance, corrosion resistance, Wide applications




4. Zincalume Corrugated Roof Sheet special parameters compared with the zinc coating
A small but important amount of silicon is included in the coating alloy. It is added not to enhance
the corrosion performance, but to provide good coating adhesion to the steel substrate when the
product is roll-formed, drawn, or bent during fabrication. It combine the excellent barrier corrosion
protection of aluminum with the galvanic protection of zinc
