Florida Building Code Approved

At The French Steel Company, our custom steel windows and doors have been safety tested in laboratory conditions to ensure that your home or commercial space is protected in the event of harsh weather or forced entry. Our Florida Building Code (FBC) certification is a testament to this, requiring intensive testing against high-pressure stresses and water leakage. As a steel window company approved by the FBC, our French Steel products have been proven to withstand the most intrusive elements and heavy outbreaks that mother nature may serve. This certification allows us to install our products in hurricane-prone locations and places where extreme weather conditions pose a structural threat to most building materials.
