Apex domes are precision-engineered aluminum covers. They are fully compliant with AWWA specifications and are constructed entirely of aluminum, corrosion-resistant, virtually maintenance-free and designed for extended service life. These covers are available for new construction, retrofit applications and customized designs, and they include specialized coating and interior insulation options. When you specify Apex domes, you get strong space-frame design, clear span construction, factory-direct installation, watertight design and a dome designed to reduce vapor loss. Project pricing is competitive with any supplier.
