How long is the service life of galvanized roof sheet?

Usually galvanized steel roofs can be used for more than 30 years, but in a well-maintained state, they can be used for 60 years; if you are in a seaside or coastal industrial area, the service life of galvanized roof sheets will be longer due to weathered conditions and corrosive environments. Shorter, for longer life, you can periodically clear the roof to remove salt and acid from the surface.

Introduction of Galvalume Metal Roofing

Galvalume metal roofing sheet is coated with a mixture of 55% aluminum, 43.4% zinc, and 1.6% silicone to protect the base steel against corrosion and rust. So it is suitable for the most applications, including in extreme environments. Also, galvalume steel roof also provides smaller, smoother spangles, which makes the surface more uniform.

Galvanized Roofing Sheet VS Galvalume Roofing Sheet：
These two metal roofing sheets are steel base sheets which are applied with different coatings, and then be profiled into corrugated design for roofing. And their features significantly differ.

Galvalume sheet is coated with aluminum and zinc alloys (55% aluminum, 43.4% zinc, and 1.6% silicone), while galvanized steel is covered with zinc coating. The aluminum naturally resists corrosion to better protect the steel core against corrosion compared to galvanized sheet. That is to say, galvalume has better corrosion resistance and heat resistance than galvanized material. It is proved that the service life of GL roofing will last more than 60 years, which is 20-30 years longer than that of GI roofing sheets.
