Fire-rated Door

Fire-rated door is a critical safety component within building fire protection systems, designed to impede the spread of fire and smoke. It is widely utilized in a diverse range of settings, including residential buildings, commercial complexes, hospitals, schools, factories, and underground spaces. The primary materials employed in its construction include high-quality steel plates, galvanized steel sheets, fire-resistant wood substrates, and fireproof core materials (such as rock wool or perlite boards), complemented by high-temperature-resistant seals and fire-rated hardware. Throughout the manufacturing process, strict adherence to fire-rating standards is maintained; the doors undergo a rigorous series of procedures—including cutting, welding, core filling, surface coating, and high-temperature testing—to ensure structural stability and verify that their fire-resistance performance meets all requisite standards.
