(ii) Structural features of steel and wood fire doors
Steel door core, secondary external patent environmental protection, flame retardant, heat insulation and fireproof composite board with modeling finish. Based on the unique advantage of fire protection relying entirely on the plate itself without the traditional technology of filling fire prevention makes the combined plug-in design possible; The interior and exterior door panels and interior and exterior door cover lines are dismountable rear mounted, the door frame adopts the integrated on-site installation structure of accessories, the frame materials are standardized and dismountable combination, high precision, convenient installation and transportation, which not only solves the problem of fireproof broken bridge, but also plays a new effect of rear decoration.
Steel and wood are combined with Yin and Yang to face the stress. After fixing the screws in the inner plate, hang the outer plate and tighten the screws around the sides, so that the stresses cancel each other out. The two materials of steel and wood are complementary to each other, and the structural stability is better than the traditional wood and steel doors. Wood veneer lines by metal components bidirectional positioning and fastening, positioning, deformation prevention, easy to install firm and reliable.
3. Strong applicability
Steel and wood fire door frame installation general civil plaster, steel frame than wood frame is less susceptible to damage. Additional steel frame is in basement and the place such as coastal shade tide, steel frame avoided the malpractice of wooden frame easy bibulous deformation.
4. High cost performance
Steel wood fire door price is lower than steel fire door price, and wood fire door price is equivalent, and wood fan dead weight than steel fan light, open flexible, in the frequently open channel location, steel frame hinge fixed than wood frame to be strong and durable.
5, the appearance can be decorative
Steel and wood fireproof door frame can be installed in the middle, or can be installed on the outside with buckle edge. The external buckle edge can be selected. The company's conventional buckle edge has 2 cm flat buckle edge, 5 cm flat buckle edge and 5 cm flower buckle edge. The style is more diverse and beautiful than the wooden door.
6. Easy installation
Steel and wood fire door hardware is generally installed in the field, and steel and wood doors under the usual circumstances is the box fan assembly factory, reduce the site installation costs, fixed steel frame is more rapid and convenient than wood frame.
