MGO Rock Wool Sandwich Panel

This panel combines a magnesium oxide (MGO) layer with a rock wool core, bonded between color-coated steel sheets. The MGO layer provides additional rigidity and surface flatness, while the rock wool core delivers thermal insulation and fire resistance. The continuous production process ensures uniform core density and strong adhesion between all layers, resulting in a panel that maintains its shape and performance over years of use. The tongue-and-groove joint design simplifies alignment and creates tight seams, reducing air leakage and improving overall building efficiency.

Rock wool is an inorganic material that does not burn and can withstand high temperatures, making this panel a reliable choice for projects with strict fire codes. At the same time, the MGO layer adds compressive strength and helps prevent surface indentation. The panel's balanced properties – fire resistance, insulation, and stability – make it suitable for both wall partitions and ceiling systems in clean environments. The smooth steel surface is easy to wipe clean, which is essential in spaces where hygiene is a priority.

Our factory has been producing sandwich panels for over two decades, supported by a dedicated R&D team and a 5,000 m² production base. We control quality from incoming steel coil inspection through to finished panel testing. Each batch is checked for thickness, flatness, core adhesion, and edge straightness before packaging. While we do not offer OEM/ODM services, our mature product line covers a wide range of specifications, and we can help customers select the most suitable configuration for their project needs.

Standard panel thickness options are 50 mm, 75 mm, and 100 mm, with a width of 1150 mm and length customised per order. Steel facing thickness ranges from 0.35 mm to 0.5 mm, and buyers can choose between colour-coated steel and stainless steel finishes. Production lead time for standard orders is typically around 10 working days. We provide regular progress updates – from manufacturing to inspection, packing, and loading – so customers can coordinate site preparation and logistics with confidence.

This panel is widely used in hospital cleanrooms, GMP pharmaceutical workshops, food processing plants, laboratories, biotechnology facilities, electronics manufacturing cleanrooms, precision instrument production areas, and public building interior partitions. Its combination of structural stability, fire safety, and easy maintenance makes it a versatile choice for demanding environments.
