The GRC composite wall panel is in low alkalinity cement mortar as base material, alkali resistant glass fiber as reinforcing material, made of sheet metal surface layer, built of reinforced concrete rib and filled with thermal insulation material in the core, with method of pedestal, into the new light composite wallboard.

Due to the adoption of the composite structure of GRC surface layer and high thermal resistance of the core material, so GRC composite wallboard has high strength, high toughness, high anti permeability, high fire resistance and high weather resistance of, and has good heat insulation and sound insulation performance.

Production of GRC composite wall panels of the same material and other GRC products. Core layer is available now, we poured cement expansion perlite mixture, also can use prefabricated insulation material (such as rock wool board, polystyrene foam board, etc.). Generally uses the anti - hit forming process, the formation of the wall panels of the surface contact with the surface of the template, so the effect of the quality of the wall panels is better. The GRC surface layer of the wall panel is generally produced by direct injection method. Made of C30 pea stone concrete reinforced concrete rib built by welding the steel skeleton and sulphoaluminate cement early strength.

According to the type of wall panels, GRC composite wall panels can be divided into bay and single plate and double standard width of a room large plate; according to the classification of thermal insulation materials used, cement perlite composite external wall board, rock wool board composite external wall plate or a polystyrene foam board composite wall plate..
