China Magnesium Matrix Science and Technology Group keep investment in studying and production free of chloride magnesium oxide-based high-end fiber cement board in brief called Mag GRC Board and high-end fiber cement drywall that is usually called for Free Chloride Magnesium Oxide Board in brief of MGO Board these two series Magnesium Matrix Boards all is with feather of excellent anti-fire ability and non-combustible. And then we develop the Mag GRC fireproof sandwich mineral insulation EWI system, and also mag GRC Terrazzo board for the decorative application. And then MGO SIPs panels. Our products are based on our core advanced Mag GRC and Mag GRC board, which is green, fireproof, waterproof, sound insulation, pest resistance, mold resistance, earthquake resistance. A non-combustibility grade is Class A1 and resistance lasts 1-4 hours, and it also fixed the defect of back to halogen/corrode the metal/strength lost with time quickly of traditional Portland GRC Board and MGO board.
