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. Below let’s review the difference between galvanized roofing sheets and galvalume roofing sheets.
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.
The galvalume roofing sheets price ranges from $600 to $900 per ton. Let’s estimate how much you will spend installing a galvalume steel roof. The weight of per square galvalume sheet (0.45 mm in thickness) is about 4.25 kg. Let’s suppose your roofing sheets is 1220 * 2440 mm. The weight of per piece is about 12.65 kg. So per ton equals about 70-80 pieces roofing sheets.
Before making estimate cost, you need to measure the area of roofing and carry out how many pieces roof panels you need. Please note that the overlaps during installation. Then confirm the thickness, width, length of roofing sheet, which matters the bearing strength. So you need to choose according to the local weather, and use environments.
