Galvanised Roofing Corrugated Steel Sheets AZ120 1.2mm DX51D

Corrugated Hot-dip Galvalume ALU-ZINC Roofing Sheet AZ120 1.2mm DX51D

Introduction 

Aluminium-zinc is often used as a cost-effective method of protecting aluminium against rust and corrosion and prolonging its service life.

ALU-ZINC also offers good heat resistance. The heat-reflecting aluminium content is twice that of galvanised steel, making GL a frequently used thermal insulation material.

Product advantages

Thermal reflectivity: ALU-ZINC roof tiles have a very high thermal reflectivity, twice that of galvanised steel, and are often used as a thermal insulation material.

Heat resistance: aluminium-zinc alloy steel sheet has good heat resistance and can withstand temperatures above 300 degrees Celsius, similar to the high temperature oxidation resistance of aluminised steel sheet, and is often used for chimney flues, furnaces, lamps and fluorescent lamp covers.

Corrosion resistance: The corrosion resistance of aluminised zinc sheet is mainly due to the protective function of aluminium. When the zinc is sanded, the aluminium forms a dense alumina layer that prevents corrosion-resistant substances from further corroding the interior.

Cost-effectiveness: as the density of 55% AL-Zn is lower than that of Zn, the surface area of an aluminium-zinc coated sheet is more than 3% higher than that of a galvanised steel sheet with the same weight and layer thickness.

Applications
Aluminium-ZINC steel sheet is widely used in roofing and cladding of urban residential buildings, renovation of old buildings, industrial sites, new buildings in the countryside, single-family houses in the countryside, light steel frame houses, railway stations and large transport hubs, conference and exhibition halls, stadiums, exhibition halls, large public buildings, public utility buildings, large shopping malls, commercial facilities and other architectural roofing and cladding systems. Aluminium clad zinc roof tiles can also be used for ordinary residential buildings, they can also achieve good results, making it a more frequently used material in the construction of buildings.
