Product Introduction
Fireproof Magnesium Plate MGO Board
Fireproof Magnesium Plate, commonly known as MGO Board, is a premium inorganic fire-retardant building panel crafted from high-purity magnesium oxide (MgO) as the primary bonding agent. It is formulated with environmentally friendly magnesium sulfate (MgSO₄) as a modifier, reinforced with fiberglass mesh, and blended with inert inorganic fillers like perlite and talc. Through a sophisticated production process involving precise ingredient mixing, high-pressure compression, and controlled temperature-humidity curing, this board achieves Class A1 non-combustible performance. What sets it apart is its integration of fire resistance, moisture resistance, eco-friendliness, and structural stability, making it a versatile solution for addressing fire safety and durability challenges in various construction scenarios-from residential and commercial buildings to industrial facilities and public infrastructure.
Advantages of Fireproof Magnesium Plate MGO Board
1 Top-Tier Class A1 Non-Combustible Performance
MGO Board maintains non-combustible properties even at high temperatures of 800–1000℃, without melting, burning, or releasing flammable gases. The embedded fiberglass mesh ensures structural integrity during fires, preventing collapse and effectively blocking flame propagation. Unlike traditional fire-retardant materials, it emits almost no toxic fumes (e.g., formaldehyde, carbon monoxide) when exposed to fire, meeting strict smoke density and toxicity standards (EN 13823, ASTM E84). Its fire resistance duration can be adjusted by varying the board thickness, eliminating the need for additional fireproof coatings and simplifying compliance with fire safety codes for different structures.
2 Inorganic Composition Ensures Moisture Resistance & Longevity
Composed entirely of inorganic minerals, MGO Board has a stable crystal structure and contains no cellulose, which avoids the risk of rot, mold, or insect infestation. With a water absorption rate of ≤15%, it remains dimensionally stable even in high-humidity environments (e.g., 90% relative humidity) or after short-term immersion. This makes it ideal for use in basements, bathrooms, coastal buildings, and industrial workshops where moisture is a persistent issue. Additionally, it is resistant to aging, UV radiation, and mild acids/alkalis, boasting an expected service lifespan of over 25 years-3 to 5 times longer than plywood or fire-retardant gypsum board.
3 Lightweight & Easy to Process, Boosting Construction Efficiency
Compared to cement fiberboard, MGO Board is 30–50% lighter (e.g., a 12mm thick board weighs approximately 26kg per sheet), allowing for manual handling and reducing transportation and lifting costs. It can be cut, drilled, grooved, and nailed using standard woodworking tools, without the need for specialized equipment, making it easy to adapt to irregular construction areas such as around pipes and corners. The tongue-and-groove or shiplap edge designs enable tight, quick splicing, and it is compatible with steel keels, wood keels, and concrete substrates. Overall, it improves construction efficiency by up to 40% compared to traditional fireproof materials.
4 Eco-Friendly & Non-Corrosive, Widening Application Scope
Made from natural minerals and fiberglass mesh, MGO Board is free of formaldehyde, asbestos, and heavy metals, with no VOC emissions. It holds ISO 14001 environmental management system certification, CE certification, and SGS test reports, making it safe for use in sensitive spaces such as hospitals, schools, nurseries, and data centers. The MgSO₄-based formula is non-corrosive to steel keels, bolts, and wood components, eliminating the need for additional anti-corrosion treatments and enabling seamless integration with steel-framed, wood-framed, and concrete structures. Furthermore, the inorganic materials can be crushed and reused as building aggregates, reducing environmental impact.
5 Versatile Applications, Realizing "One Board for Multiple Uses"
MGO Board's comprehensive performance allows it to be used across a wide range of construction scenarios:
Fire protection systems: Fire partitions, firewall cladding, stairwell enclosures, elevator shafts, and data center server room walls.
Building envelopes: Interior and exterior walls, ceilings, and partition walls in residential and commercial buildings.
Functional substrates: Floor underlayment (paired with LVT, vinyl, or ceramic tiles), exterior wall cladding (with waterproof coatings), and industrial workshop walls (resistant to chemical splashes).
Special infrastructure: Tunnels, subway stations, shopping malls, and industrial warehouses with high fire safety and load-bearing requirements.
Magnesium Oxide Wall Board offers unmatched performance with its fire resistance, lightweight and high-strength structure, moisture and mold protection, and superior durability-making it a better choice than traditional materials like gypsum, cement, and wood-based boards.
Fire Retardant Board is a mineral matrix engineered board designed to contain a fire within a compartment of a building by acting as a barrier to stop the spread of heat, smoke, fire and gases. It can be used for steel protection, walls, ceilings, ducts, concrete protection and sealing penetrations and voids.
Fireproof wall board, also known as fire-resistant wall board or fire-rated wall board, is a type of building material designed to resist the spread of fire and provide some level of protection in case of a fire. It is commonly used in construction to create fire-resistant partitions, walls, and ceilings.
Magnesia boards are used in place of traditional gypsum drywall as wall and ceiling covering material and sheathing.
The non-combustible property of magnesium oxide board comes from its inorganic mineral components and stable structure.
Decorative panels, with magnesium oxide board as the base material, are widely used in interior decoration industry. These panels are extensively used in high-end residential, commercial and industrial projects for interior decoration.
As a sheathing board, magnesium oxide board has core competitiveness in non-combustibility, water and corrosion resistance, and structural stability, while also being convenient for construction and environmentally friendly.
Magnesium oxide board demonstrates good mildew-proof characteristics due to its unique advantages. Its alkaline nature resulting from the main raw materials is not conducive to the growth of mold.
As the new generation of inorganic eco-friendly building materials, MGO Exterior Deck boards have become the preferred material for outdoor walkways, scenic platforms, and other outdoor construction projects due to their lightweight strength, fire resistance, moisture protection, and weather resistance.

Installation Guidelines for Optimal Performance
-
Pre-Installation Base Treatment: Ensure the steel or wooden keels are flat, dry, and free of rust or oil stains. The recommended keel spacing is ≤400mm (for 1220×2440mm boards) to guarantee sufficient load-bearing capacity.
-
Board Splicing: Adopt staggered joint splicing to avoid continuous vertical seams, which enhances structural stability and fire resistance. Leave a 2–3mm expansion gap around the perimeter of the installation area and between boards to accommodate thermal expansion and contraction.
-
Fixing Method: Use galvanized screws or anti-corrosion nails for fixation. The nail distance from the board edge should be 15–20mm, and the spacing between nails in the middle of the board should be 200–300mm. Sink the nail heads slightly into the board surface without damaging the fiberglass mesh layer.
-
Joint Sealing: For fire partition applications, fill the joints with fireproof sealant; for humid environments, use waterproof sealant to further enhance moisture resistance.
-
Subsequent Decoration: The board surface is flat (flatness ≤2mm/2m), allowing for direct painting, tiling, or installation of decorative panels without additional leveling procedures.
