Prepainted Galvalume Corrugated Roof refers to a type of roofing material that combines the benefits of prepainted steel and Galvalume coating in a corrugated profile. It is widely used in residential, commercial, and industrial buildings due to its exceptional durability, aesthetic appeal, and weather resistance. The Galvalume coating consists of a mixture of aluminum, zinc, and silicon applied to steel to provide superior corrosion resistance and enhanced longevity. The prepainted finish adds an attractive and protective layer to the Galvalume coating, offering a wide range of color options to suit different architectural styles and design preferences. The corrugated profile enhances the strength and rigidity of the roof, allowing it to withstand harsh weather conditions, including heavy rain, snow, and wind. Prepainted Galvalume Corrugated Roof offers several advantages, such as lightweight construction, easy installation, and low maintenance requirements. It provides reliable protection against UV rays, fading, chipping, and rusting, ensuring long-term performance and visual appeal. Additionally, its thermal efficiency helps to reduce energy costs by providing insulation and proper ventilation. This roofing material is commonly used for residential roofing, warehouses, agricultural buildings, and commercial structures. Overall, Prepainted Galvalume Corrugated Roof is a versatile and cost-effective solution that combines the strength of Galvalume coating, the versatility of prepainted steel, and the durability of a corrugated profile to deliver a high-quality, long-lasting, and visually appealing roofing option.

product introduction

Galvanized steel is steel that has gone through a chemical process to keep it from corroding.The steel gets coated in layers of zinc oxide because this protective metal does not get rusty as easily.The coating also gives the steel a more durable ,hard to scratch finish that many people find attractive.For countless outdoor,marine,or industrial applications, galvanized steel is an essential fabrication component.
1. Super corrosion resistance: 
under various environmental conditions, aluminum zinc coated steel coil has excellent corrosion resistance than hot-dip galvanized steel coil with the same thickness, and its service life is 2-6 times that of ordinary galvanized steel plate. Because the microcrack of aluminum zinc plating on the deformed part is smaller than that of hot-dip galvanizing, its corrosion resistance is much higher than that of hot-dip galvanizing.
Its service life order: Rural – industrial atmosphere – General marine atmosphere – serious marine atmosphere
2. High temperature oxidation resistance:
 ordinary hot-dip galvanized products usually have a service temperature of no more than 230 ℃, and will change color when reaching 250 ℃, but aluminized zinc products can be used for a long time at 315 ℃. And there will be no discoloration or deformation;
3. High refectivity: 
the reflection coefficient of aluminized and zinc products is twice that of hot-dip galvanized plates. Acting as roof and panel without painting can achieve energy-saving effect;
4. More usable area: 
the density (3.75g/m3) of the coating of aluminized zinc steel coil is much smaller than that of the coating of galvanized steel coil (7.15 g / m3). Therefore, when the steel substrate and coating thickness are the same, the usable area per ton of aluminized zinc steel coil is much more than that of galvanized steel coil
