A Summary of the Knowledge of insulated Magnesium color steel sandwich panel
Updated: Nov 25, 2020
MGO board has the characteristics of water-proof, moisture-proof, high temperature resistance, flame-retardant, sound absorption, shock-proof, insect-proof, anti-corrosion, non-toxic, odorless and pollution-free. It can be directly painted, directly veneered with ceramic tile. The surface has better coloring, high strength, flexibility, toughness, sawable, sticky and convenient decoration. It can be an type of insulation materials combined with steel sheet to be MGO sandwich panel.
MGO sandwich panel specification:
Metal sheet spec. :
Upper/lower steel plate: thickness is 0.4-1.2 mm. It can be color steel plate, galvanized steel plate or stainless steel plate.
Core Material: MGO board
1. Conventional width of machine-made sandwich panel : 1150 mm, thickness: 50 mm~100 mm, unlimited length
2. Conventional width of hand-made board: 1180 mm, thickness: 50 mm~100 mm, unlimited length
MGO original ingredients: active high purity magnesium oxide (MgO), high quality magnesium chloride (MgCI), alkali-resistant glass fiber cloth, plant fiber, non-flammable light perlite, chemically stabilized lithopone powder, high polymer, high performance modifier.
