Olympia Steel Buildings knows that the intelligent buyer wants to get the best quality building for the best price. You don’t want your roof collapsing and you don’t want the metal building to leak or to be susceptible to corrosion. Olympia Steel has worked hard to overcome these potential problems inherent in any building construction. First and foremost, the most susceptible part of a steel building or any building is the roof and one of the most important components of the roof is the roof material and coating. Olympia Steel 's roof coating is AZ55 Galvalume ® which requires no maintenance or painting and retains its original luster forever. It is comprised of 55% aluminum, 44% zinc and 1% silicone. This greater aluminum content creates a higher resistance to rust. Olympia Steel Buildings offers a 25-year rust through perforation warranty backed by the steel mills. If a hole rusts through a panel, the steel mill will replace the panel.
Some steel building companies use only an AZ50 coating on their roof panels, which only has a 50% aluminum content. And some metal buildings companies only offer a 20-year perforation warranty if a hole rusts through a panel. Some other companies use a zinc-galvanized roof coating which contains no aluminum. Roof panels with this coating will rust and corrode causing holes to form and leaks to develop.
