Galvanized Corrugated Roof Sheet

Galvanized roof shingles are made of galvanized steel sheet used for roofing and coated with zinc. The zinc coating provides moisture and oxygen protection for the base steel. According to the galvanizing process, it can be divided into hot-dip galvanized steel plate and electro-galvanized steel plate. The corrugated design will improve its strength and enable it to withstand harsh weather conditions. Common designs include wavy, trapezoidal designs, ribbed galvanized roof panels, etc. It can be used as a single-layer board, covering an existing roof, or a steel sandwich panel.

Galvanized Corrugated Roof Sheet Description

Galvanized sheet itself is more cost-effective than traditional roofing materials. In addition, it is light in weight and easy and quick to install. In addition, it is durable and recyclable and requires less maintenance. All these factors make galvanized roof panels an economical choice. Galvanized steel roof panels have a bright and smooth surface. The corrugated design is also excellent from the outside. In addition, it has good adhesion, so you can paint it in different colors. Having a galvanized steel roof makes it easy to achieve aesthetic purposes.

Scope of Application

Galvanized corrugated roof panels have good corrosion resistance and long service life. Therefore, it is widely used in industry, commerce, residence and agriculture. Its wide application includes temporary houses, garages, greenhouses, warehouses, barns, stables, sheds, factories, commercial buildings, etc.
