Fire doors are one of the fireproof separation facilities of buildings. They are usually used on firewalls, stairwell entrances or pipe openings, and play an important role in reducing fire damage.
The door leaf consists of fire -retardant Chinese fir skeleton inside of which environment friendly pertile fire board is filled,and decorative layer with fire panel. The reasonable structure makes the whole door withstand high temperatures up to 1000 ℃. The decorative surface adopts melamine veneer, which has high compressive strength and scratch resistance and can adapt to the harsh construction environment. Optional decorative surface can achieve better decoration effect.
The door frame adopts the composite structure of fire retardant Chinese fir and fire board, and adds a layer of fire board with thickness up to 8mm on the face of wood to meet the fire. The decorative style can be customized according to the needs of users. All the contact parts of door frame and door leaf are equipped with fireproof and smoke resistant expansion sealing strips, which can expand at critical time to prevent deadly smoke from passing through.
