Olympia Steel Buildings roof panels are made of 26-gauge steel with a yield of 80,000 PSI and a huge corrugation depth of 1 1/4”. The strength of the steel together with the high PSI yield and deep corrugation create tremendous protection against strong winds and heavy snow loads. Olympia's steel building roof panels are wind rated to meet the Florida building code. The Florida code number is FL-3722-R1.
The thickness of the steel panels on the sidewalls and roof of some competitors' metal buildings is only 29-gauge steel. These buildings are not as strong and are less durable than Olympia's steel buildings since the steel they use is 32% lighter than the 26-gauge steel utilized by Olympia. The competition's panel corrugation is only 5/8” in depth, half the depth of Olympia's 1 1/4” corrugation. Therefore, the Olympia steel building panel has twice the strength. Also, some companies are not wind rated and do not have a Florida approval number.
Some companies use an AZ50 coating on their roof panels, which only has a 50% aluminum content. They offer only a 20-year perforation warranty if a hole rusts through a panel - five years less than the warranty offered by Olympia. Some other companies even use a zinc-galvanized coating which contains no aluminum. Roof panels with this coating will rust and corrode allowing holes to form and leaks to develop.
Olympia's roof coating is AZ55 Galvalume®. The coating requires no maintenance or painting and it retains its original luster. It is comprised of 55% aluminum, 44% zinc and 1% silicone. The greater aluminum content creates a higher resistance to rust. There is a 25-year perforation warranty on Olympia Steel Buildings roof panels backed by the steel mills. If a hole rusts through a panel, the steel mill will replace the panel.
No matter what they say about wood and concrete, I still go for steel homes especially since I live in a place which is always the eye of the storm.
