◆ Application

Galvanized steel C channel is an effective metal anti-corrosion method, which is mainly used in metal structure facilities in various industries. Due to the characteristics of beautiful appearance and good corrosion resistance of galvanized C channel, its application range is more and more extensive.

• Buildings and bridges: glass curtain walls, power towers, communication grids, water and gas transmission, wire casings, scaffolding, houses, etc.

• Industry: chemical equipment, petroleum processing, marine exploration, shipbuilding, etc.

• Agriculture: sprinkler irrigation, warming houses.

The performance of each galvanized steel C channel is different, and the specific application is also different. We will recommend the suitable galvanized C channel model according to your actual application. If you need technical advice, please send us a message or inquiry directly.
