Detailed Description

FRP Gratings with Light Weight but High Strength

SARE Company's FRP/GRP gratings (Fiberglass Reinforced Plastic Gratings) are interwoven from glass fibers, cast resin and then molded into FRP grating plates with regularly distributed rectangle or square holes, and they have perfect bi-directional mechanical properties. FRP gratings can be widely used for the working platforms, equipment platforms, drilling platforms andwalkways of petroleum, chemical electronics, electricity, paper, printing and dyeing, electroplating, ocean exploration, sewage treatment and so on. They are the ideal choice for corrosive environments, but also can be applied to civil construction facilities.

Square-hole FRP gratings have stable structure for wide applications.

Four FRP gratings, the top one is green, second is yellow, third is white and the bottom grating is green with covered surface.

FRP gratings have various colors and different surface types according to customers' request.

Three kinds of manufacturing techniques:

  • Reciprocating filament winding process.
  • Continuous filament winding process.
  • Centrifugal pouring process.

And nowadays, manufacturers who use reciprocating filament winding process are much more than the other two production technologies manufacturers, one of the reasons is that the FRP gratings made by the reciprocating filament winding process have a wider range of applications and better applicability.

Resin system:

Features:

  • Corrosion resistantResisting to acid, alkali, organic solvents, salts and many other gases and liquid media, FRP gratings have incomparable superiority in the field of preservation. According to the practical application requirements, orthophthalic, isophthalic and vinyl resins can be chosen as matrix material FRP gratings are widely used in all the aspects of chemical preservation, and they are replacing carbon steel, stainless steel, wood and non-ferrous metals.
  • Lightweight & high strengthBecause FRP grating is a composite of resins and fiber glasses, its density is less than 2 kg/dm3, which is 1/4 of the steel density and 2/3 of aluminum density. FRP grating's strength is ten times of RPVC, and its absolute strength level is higher than aluminum and ordinary steel. Its lightweight can greatly reduce the basic support, so as to reduce the material costs of the project. FRP gratings are easy to cut and install, no flame and large lifting equipment is needed, only need a small number of manual and electric tools, so as to reduce the installation costs.
  • ErgonomicWorkers would get tired after a long time working on solid concrete or steel platforms, but FRP gratings can ease the strain their backs, feet and legs, so as to increase their comfort and work efficiency.
  • Good thermal performanceFRP grating has low thermal conductivity - 1.25 - 1.67kj/(m.h.k) at room temperature, which is only 1/100 - 1/1000 of metals, therefore it is an excellent insulating material. In the case of instantaneous ultra-high temperature, FRP gratings are ideal for thermal protection and ablation resistance.
  • Inflaming retardingThe flame propagation rate of ordinary flame retardant grating does not exceed 25, and the flame propagation rate of superb flame retardant vinyl grating does not exceed 10. The oxygen index is not less than 28.
  • Security with good electrical propertiesFRP grating has excellent electrical insulation properties as an insulator, and it can still protect good dielectric properties under high-frequency. Due to the good microwave permeability, FRP gratings have been widely used in radar and radome. Due to the no breakdown under 10KV voltage and no electromagnetic, FRP gratings can be used on equipment sensitive to magnetism. And the special structure of FRP grating has the features of anti-slip and anti-fatigue.
  • Uniform colorThe color can be arbitrarily chosen, according to the request of customers, improving the workplace environment.
  • Outstanding designabilityA variety of structured FRP gratings can be designed to meet the customers' requirements, letting the products have good integrity. And the materials can fully satisfy the product performance, such as corrosion resistant, instantaneous high temperature resistant, high tensile strength and good dielectric property.
  • Good manufacturabilityOne-step molding process, prominent economic effect.
  • Have good overall economic efficiency
  • Anti-agingMore than twenty years of service lives.
