Depending on building specifications, the interior can feature polystyrene, polyurethane, temperature rise, or steel-stiffened cores. These assemblies offer structural strength, security, and fire-rated protection for commercial openings, and can be paired with custom or standard welded and cut-and-notch steel frames.
