Structural Mgo Sheathing
ROCKMAX structural mgo sheathing, it’s made from compressed magnesium oxysulfate cement by unique formula design. ROCKMAX sheathing has great bending strength and screw holding strength as good as OSB sheathing, beside it is fireproof, waterpoof, termite resistant and 100% formaldehyde free. ROCKMAX sheathing is an innovative building board for fire rated sandwich insulation panel(Mgo Sip), LFS/LGS shear wall and offsite modular wall system.
