How Long Does Galvanized Steel Roofing Last?

Generally, the galvanized steel roof can last more than 30 years. Under ideal conditions, it can live for up to 60 years. However, if you are near or on the beach, or in industrial areas, your roof may last only 10 years depending on weathering conditions and corrosive environments. Actually, the service life of galvanized steel roof panels mainly depends on the zinc coating thickness and the use environment. To prolong the service life, you can periodically wash your roof to remove the salt or acid from the surface. Besides, you need to choose suitable corrugated roofing sheets for your roof.

Do Galvanized Steel Roof Panels Rust?

The answer is yes, especially when exposed to weather conditions over a long time. But it is very slow. Galvanized steel roofing sheet is simply covered with a zinc layer on the surface to prevent oxidation and rust. However, when the zinc coating is broken, the substrate will rust. Below are some tips for you.

 

 
1. Choose Suitable Zinc Coating Thickness

 

Generally, the thick the zinc layer, the longer the service life. Our GI roof is mainly made of hot-dipped galvanized steel sheet, with a zinc coating of 40 g/m2 to 275 g/m2. If your roofing sheets are used in corrosive environments, such as marine or chemical industrial areas, you can choose a thicker zinc coating roof.

2. Paint With Color Coatings

In order to prolong the service life of your roof, you can also paint the roofing sheets to prevent rust and maintain their beauty.

3. Periodical Maintenance

Galvanized steel roofing sheets are almost maintenance-free. But regular maintenance, such as cleaning with water, will remove the corrosive factors to prolong its service life.

Which Is Better Galvanized or Galvalume Roofing Sheet?

Actually, it depends. Both galvanized and galvalume sheets are widely used as roofing materials. Galvanized sheet is covered with pure zinc; while galvalume coating includes zinc, aluminum, and silicon. The combination of zinc and aluminum offers GL sheets better corrosion and heat resistance. The data show that GL roofing can last as long as more than 50 years. Besides, it offers a smoother appearance with uniform spangles. In this case, the galvalume roofing sheet is better. However, galvalume coating is easy to break if it is scratched or dented, such as the cut edge. During installing the GL roofing sheet, it is necessary to paint the cut edge. In addition, galvalume sheet is not suitable for where animals are confined, since the ammonia gas will degrade the metal. Just choose the right roofing sheet according to the use environment and your budget. If you want more information, please contact us!

The quality of galvanized roofing sheets mainly depends on the zinc layer thickness. The thicker the zinc coating, the better the corrosion resistance of galvanized sheet. In addition, we also need to take its performance into consideration, such as its tensile strength and yield strength. The zinc layer of quality galvanized sheet will not fall off after being bent by 180 degrees. Also, it will not break during the tensile test. So please pay more attention to the quality rather than the price only.
