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