Housing assembly bo magnesium fire board (13651785080)
Housing assembly, fire wall, steel structure building fire magnesium preferred bo bo magnesium fireproof wall plate, glass magnesium fireproof wall main materials are inorganic material, anti-aging ability, good durability, can effectively resist alkali, water erosion, the use of the structure design life of 50 years. Freeze-thaw cycle of 100 times, the volume and intensity of almost no change.
Bo magnesium fireproof wall during normal use without special maintenance, low use cost. When the local damage in the roof repair directly, if indeed in plate when necessary, can be single board replacement, will not affect the whole structure.
High strength, durable: the main materials are inorganic material, anti-aging ability, good durability, can effectively resist alkali, water erosion, the use of the structure design life of 50 years. Freeze-thaw cycle of 100 times, the volume and intensity of almost no change.
Fire: under standard load, fireproof limit is 2 hours, not burst in the process of combustion, don't release any poisonous gas, no smell, no smoke, not only has excellent fireproof performance, and comply with environmental requirements of the modern architecture.
