Fireproof Building Materials Magnesium Oxide Board

Fireproof magnesium oxide board

Xinlong magneisum oxide board is made of filling materials such as sawdust and all kinds of crushed plant straw( you can select any one kind) and serveral chemical raw materials which are token as modified material after special technology.The board has such features:Quickly hardending, high strength, large-format, fireproof, damp-proof and good water-pr fire resistant boards oof performance.It can be nailed, planed and stuck.So it can be used widely at indoor decoration, such as wall skirting and ceiling of market, hotel,club, station, building and living room.And it also can get large usage at top-grade furniture, door and partition.This product is made from waste materials, and it is ideal product which can replace all kinds of wood board with reasonble and good quality.Gray color mgo glass magnesium board board is getting more and more populor by now, they can be used instead of fiber cement board,because of similar color-grey color.However be compared with fiber cement board, grey mgo board is fireproof A grade,high quality .It is easy to cut ,to install.Most important is that mgo board is low cost building material for projects, will make huge profit for you.More detail informaiton ,pls go on to read it as follow:
