Product Details

The door frame is made of 1.5 mm steel plate and reinforced internally with 5 mm thick square tubes, improving the overall structural strength and stability of the frame.

The door leaf is made of 1.0 mm steel plate, with 3 mm thick square tubes used internally as the reinforcing framework. This structure strengthens the door leaf and improves its resistance to deformation under high pressure.

The internal core is filled with perlite fire-rated board, allowing the door to provide not only wind pressure resistance and blast-resistant protection, but also fire-resistant performance.

An anti-detachment chain can be added as an option to provide secondary protection and improve safety during use.

The surface finish is available in two options: RAL color chart electrostatic powder coating or wood grain finish. The wood grain finish can be achieved through heat transfer printing or by applying PVC film on the steel sheet surface. Wood grain colors can also be customized based on color samples provided by customers.
