High Strength Composite Grating Sheet for Sale

Description
 
FRP grating is a perforated sheet by using glass fiber as a reinforced material, unsaturated polyester resin as matrix through a special composite process. FRP grating can be used as a structure material applied floor in a corrosive environment, trench cover, platforms, ship decks, stairs, walkway and so on.


 
Grating adopts fiberglass braiding process, resin cast integrally molded technique for its excellent mechanical characteristics. It can be widely used in petroleum, chemical and electronics, electricity, paper, printing and dyeing, electroplating, ocean exploration, sewage treatment and other industries to serve as working platform, equipment platform, drilling platforms, walkways, etc. It is the ideal product applied in corrosive environments, but also applies in civil facilities.
 
FRP grating characteristics:
Corrosive resistance
It has a very excellent resistance to acid, alkali, organic solvents, salts and many other corrosive gas and liquid medium. In the field of anti-corrosion it has incomparable superiority. Based on actual situation, it can be economically choosen phthalic, isophthalic , vinyl resin as matrix material.
Lightweight, high strength, easy to cut and install
Made by resin and fiberglass, the grating having a density of no more than 2 kg per cubic decimeter, only 1/4 of the steel, 2/3 of the aluminum. Its strength is 10 times of rigid PVC, and absolute strength exceeds ordinary steel and aluminum. Its light weight can greatly reduce the base support, thereby reduce the material cost of the project. The FRP grating can be easy cut and installed, no need of large lifting equipment. For installation only needs a small amount of workers and electric tools, so the installation costs are greatly reduced.
Anti-aging
In theory, the service life of 50 years.
Flame-retardant
For common flame-retardant grating the flame propagation rate (ASTM E-84) does not exceed 25; For flame-retardant vinyl grating the flame propagation rate does not exceed 10. Oxygen index is no less than 28 (GB 8924).
Safety 
The grating has excellent electrical insulation, no breakdown under 10KV voltage; No electromagnetic properties. It can be used on magnetic sensitive equipment; FRP grating's special structure also has a non-slip, anti-fatigue properties.
Color
Color can be arbitrarily chosen. Colors can be customized according to customer requirements for improving the production workplace environment. The ordinary grating colors: yellow, gray, green, blue, red as well as transparent or translucent and so on. During using you can choose one single color or can combine several colors.
Flexible design
Flexible size, easy to cut, dimensional stability.
 
FRP gratings (FRP grid) applications:
floor, trench cover, platform, walkways, stairs tread etc. in water treatment, chemical industry, oil industry, textile mills, power industry, metal surface treatment, marine food processing plants, transportation, beverage industry, pulp processing plants, electronics industry, meat processing plants, car wash / car beauty shop, other fileds like corrosion-resistant shelves, decorative purpose, square fountain, scaffolding, civil facilities, aquaculture fence and double floors, etc.

 

Grating types
Grating with smooth surface, grating with gritted surface, grating with concave surface, mini-mesh double layer grating, grating with cover plate, grating with gritted cover plate, grating with grinded surface



Grating specifications 
Grating fittings (clamps)
Characteristics of different FRP grating connectors:
1. L-type connectors: for moderate loads and special positioning connection of bracket.
2. M-type connector: stable fixing, for grating bracket and bracket positioning connection .
3. C-type connectors: for connecting side edges of two grating plates integrally.

 

FRP grating installation
FRP grating installation for trench cover
1. According to grating single-cell size, adjust the trench size as much as possible to keep close side of the grating after cutting and to keep the integrity of the cell for nice vision effect.
2. The supporting of FRP grating on a concrete foundation is at least 50mm wide. Gap between the grating and concrete is 3-6mm.
FRP grating installation for platform
1. The supported side of the grating over the steel beams is at least 40mm wide. The installation gap between the grating plates is 6mm. The gap between grating and concrete columns is 10mm.
2. Between the grating and steel beams fix with M-type or L-type clamp. At least 4 pieces for each grating. C-clamps should be used for connecting the side edges of two adjacent and non-supporting gratings. At the center of each 1.8m long at least use one piece.
FRP grating installation for stairs
1. FRP grating should be installed within the frame or bracket of tread. The frame and bracket may be steel or fiberglass.
2. The gap between the FRP grating and frame is 3-6mm, for each tread fix with each eight fixed clamp. For each corner use 2 pieces. The grating can also be directly fixed to the bracket.

FRP grating maintenance
1, During usage please use washing liquid to clean the dust, dirt on the surface. No need of other maintenance measures.
2, During usage avoid direct contact with welding, oxyacetylene flame and other open flame in the course of steel structure and equipment maintenance.
3, During usage avoid drag, impact damage and paint contamination of steel material and tools in the course of various steel structures and equipment maintenance.
