MgO subflooring boards, also known as Magnesium Oxide subfloors, are high-performance, fire-resistant panels specifically designed to provide a stable and durable foundation for flooring applications. These boards are made from magnesium oxide and fortified with additives to enhance their strength and water resistance. They offer a smooth surface that is ideal for the direct installation of finished flooring materials. Known for their dimensional stability, impressive load-bearing capacity, and excellent moisture resistance, MgO subflooring boards are perfect for a wide range of construction projects that require a robust and reliable subfloor solution.
OCM's fireproof MgO boards are distinguished by their use of magnesium sulfate (MgSO4), setting them apart from those made with magnesium chloride (MgCl2). This choice of sulfate significantly enhances the board's water resistance, preventing the reabsorption of moisture and thus circumventing the 'sweating' and metal corrosion issues that plague MgCl2-based boards. With OCM's MgO boards, you can rest assured that they are free from the pitfalls of 'weeping' and 'rusting', delivering a dependable and long-lasting solution for your fireproof construction requirements.
OCM incorporates bamboo fiber into its products, which is known for its non-absorbent nature and exceptional strength and durability. With a higher specific compressive strength compared to wood fiber, bamboo fiber offers superior performance. It is resistant to fire, water, and mildew, and provides effective insulation against both sound and heat, making it an ideal material for our high-quality construction products.
Our sanded board features a precision-engineered structure, including a distinctive tongue and groove design for flooring substrates. This design ensures one long side is grooved to perfectly match the tongue on the opposite side, creating a seamless and secure fit. The board offers a smooth, safe surface for use. It boasts a high bending strength of at least 20-25 Mpa, capable of withstanding a concentrated load of up to 370 kgs and a uniform load of up to 500 kgs over a 450mm joint center, demonstrating its reliability and durability in flooring applications.
