Galvalume® vs. Galvanized

While both metal roofing products were developed to essentially sacrifice themselves to protect the steel sheeting they coat, the above exposure comparison shows that Galvalume® performs (up to nine times) better in fighting corrosion as compared to Galvanized coating. While Galvalume® can initially show signs of corrosion faster than Galvanized, it has a sacrificial property that will prevent the corrosion from growing whereas once corrosion has started on a Galvanized panel, it can continue to corrode until panel integrity is lost.

According to a study released by the Metal Construction and Zinc Aluminum Coaters associations, the longevity of a low-slope unpainted Galvalume® standing-seam roof is 60 years. (Additionally, primer and paint adhere better to Galvalume®-coated panels and they carry a 20-year limited warranty while galvanized panels do not, making them a smarter long-term investment for homes, agricultural buildings or commercial properties.

  4. Rust can cause severe damage to metal roof if not treated on time. An early detection and repair can leave you from worries. Metal roofs are an eco friendly option and metal roofs are recyclable too. Selecting the right material of metal for your home or commercial building is of utmost importance so as to increase the longevity and durability. A galvanized metal sheet is a steel sheet with a thin layer of zinc coating and galvalume metal has steel panels with an aluminium-zinc alloy coating. The mixed coating on galvalume metal is the very effective to prevent rust. Here are some FAQ in the posts http://www.countrytowne.ca/faq/ about metal roofs that can be a beneficial read for many.

  7. For some DIY individuals, the most clear activity is to repair the rooftop themselves. However, material repairs, it must be noted, can be very dubious and unless you are a material temporary worker yourself, you should grapple with the way that you may need to employ an expert roofer. realy good service

  11. Safe and nontoxic,

    spray foam meets requirements and specifications because it expands to fill cracks, even in hard to insulate areas around electrical outlets and pipes. Unlike fiberglass, spray foam insulation reduces energy wasting air leaks, noise, pollution, and drafts. foam insulation company CT
