on many occasions. For example, glass?reinforced?plastics grating in carwash is generally used for holder or stand. Molded glass?reinforced?plastics grating is usually used for walkways, platforms, tree grate fence and so on. It is widely used in sewage treatment plants waste board and residential parking lot.
Bearing profiles can moulding FRP geogrids after demoulding. The upper layer is plate structure: It is mainly formed by connecting pultrusion moulding "I" or "T". At the same time glass fiber twistless roving is spreaded in large metal mold with the lower pultrusion geogrids is hand paste. Its role is to connect the bearing profile. According to need, various extrusion molding round bar or abnormal bar interval material are used. Pultruded FRP geogrids mainly consists of three parts and then formed by curing. Pultrusion moudling "I" or "T" profile are used as a bearing rod with various pultruded round bar or abnormal bar (adhesive bar) are used as cross bar by adhesion agent. According to a certain distance, transverse rod and the bearing rod is fixedly connected together to form the FRP geogrids. The surface of molding FRP geogrids in the production can be sealed and plastic geogridsis produced by machine. Its function is to adjust and fix the void ratio of the glass fiber reinforced plastic grating.
