Product description:
Sulfate board is a kind of new green and fireproof building material. The mgso4 board is going to replace the traditional mgo board due to more and more problems come out from the normal mgo board like "sweating", corroding the nails &screws, the color of the boards turn yellew etc. We find a best way to solve these problems, our meisen mgo board absolutely not getting damp and rust steel, it's 100% no magnesium chloride.
