Molded grating process

Molded grating is manufactured by laying continuous glass fibres in the mould in the direction of vertical and horizontal, and througly wetted out with resin, layer by layer. When the weaving process is completed, the mould is heated to cure the panel. After curing, the panel is ejected from the mould. The standard panel would have meniscus (concave) top surface. Any process such as post applied grit could be bonded after as a secondary operation. This continuous process produces an integral, one piece panel, which offers excellent corrosion resistance as well as bi-directional strength.

 

FRP grating density is about 1.8, is only a quarter of the steel, aluminum two-thirds.10 times the strength of rigid polyvinyl chloride (PVC), absolute strength more than aluminum and the level of the ordinary steel.

Comparing with other floor materials, FRP moulded grating provides a series of benefits, unmatched impact resistance, while the strength-weight-ratio is only one-fourth of that of steel grating. It is easy to cut and install. FRP moulded grating is made of continuous fiberglass fully soaked in unsaturated polyester resin giving a uniform structure and perfect bi-directional mechanical properties.

Standard resins being used include Orthophthalic, Polyester resin, Isophthalic polyester, Vinyl ester resin. Vinyl ester grating provides extremely high corrosion resistance.The surface of FRP moulded grating can be concave top, flat top, grit top,Decorative Pattern Cover,Grit Cover and Smooth Cover.

 

GRP grating plastic grille for chemical plants walkways
FRP grating (also known as Fiberglass reinforced plastic grating, GRP grating, glass reinforced plastic grating or fiberglass grating) is a composite material manufactured by combining a matrix of resin and fiberglass.

 

FRP grating is made of glass fiber interlacing and resin casting. The glass fiber reinforced plastic grille plate with many regular distributed rectangles and square spaces has two way mechanical properties. Widely used, it is an ideal product in the corrosive environment and also applicable to civil

Hengshui Aoliande Trade Co., Ltd. not only have manufacture ability, but also has design ability of material, structure and products, our company can provide customers with technical advice, supply of goods and material, transportation, installation supervision etc service.

1.Are you a trading company or a manufacture factory?
Our factory found in 1992, we're professional GRP grating manufacturer in China.

 

2.What tools are required to install FRP grating?
The installation of FRP could be done by using: a fine tooth saw blade, carbide drill bit, the manufacturer’s recommended trowel, and a laminate roller that will be used to ensure maximum adhesion between FRP and the surface where it is being installed.

 

3.Can your factory customized the products for clients ?
Yes, we supply customized.

 

4. In what size does FRP is manufactured?
Fiberglass reinforced panels usually are manufactured in 4 foot by 8 foot sections and with some architectural trims and/or moldings. For small applications and surfaces the FRP could be cut to exact dimensions by using a power saw with a fine tooth, carbide tip blades or masonry blades. FRP Panels in 1mm thickness weigh about 1.5kg per square meter
