FRP Moulded Grating Manufacturer

FRP Grating is a structural material that uses glass fiber as a reinforcing material and unsaturated polyester resin as a matrix, and is composited by molding or pultrusion. It combines the high strength of glass fiber and the corrosion resistance of resin, and performs well in strength, toughness, corrosion resistance, insulation, and aging resistance. Compared with traditional steel or wooden gratings, FRP gratings are not only light, easy to carry, and easy to install, but also do not require regular maintenance, have a longer service life, and have significant economic benefits.

FRP gratings are widely used in petrochemicals, electroplating workshops, water treatment plants, offshore platforms, shipbuilding, metallurgy, electricity, textiles, food processing and other fields, especially in operating platforms, walkways, stair treads, gutter covers, etc. in corrosive environments. The surface of the product can be treated with sand or convex anti-slip treatment to enhance safety. According to different scenarios and load requirements, FRP gratings can be customized with different mesh sizes, thicknesses, colors, and resin types (such as orthophthalic, isophthalic, vinyl, etc.).

In addition, FRP grating has good electrical insulation and thermal insulation properties, is non-conductive and non-thermal, and is particularly suitable for places with high safety requirements, such as power plants and aerial work platforms. Since it does not contain metal components, it will not cause electrochemical corrosion and will not interfere with the operation of instruments and equipment. As a new type of environmentally friendly composite material, FRP grating can not only improve the operating efficiency of industrial facilities, but also save a lot of maintenance costs for factories. It is one of the ideal structural material choices for modern industrial infrastructure.

7.Frequently Asked Questions (FAQ)

What is the load capacity of FRP grating?

• Load capacity depends on the panel thickness, mesh size, span, and load type. For example, a 38mm thick molded grating with 1-meter span can typically support 3–5 kN/m² uniform load. Heavy-duty applications may require thicker panels or pultruded gratings.

How do I choose the right resin type?

• Orthophthalic resin is suitable for general use;
• Isophthalic resin offers improved corrosion resistance;
• Resin vinil ester provides excellent chemical and heat resistance. Choose based on the environment (e.g., acid, alkali, salt, temperature).

What anti-slip surfaces are available?

• FRP grating can be manufactured with gritted surface, concave surface, atau meniscus top.
  Gritted offers the highest slip resistance (up to R13), while concave and meniscus surfaces are easier to clean and suitable for hygienic areas.

Is FRP grating fire-retardant?

• Yes, fire-retardant options are available. Products can be manufactured to meet ASTM E84 Class 1, EN 13501-1, or other fire standards. Be sure to specify fire resistance when ordering.

Can FRP grating be cut or drilled on site?

• Yes, it can be cut using diamond or carbide-tipped saws. Cutting should avoid main load-bearing bars when possible. Exposed edges should be sealed with resin to maintain corrosion resistance.

What are the standard fixing methods?

• Common fasteners include M-clips, J-clips, Dan L-clips (usually stainless steel). In outdoor or vibration-prone areas, mechanical bolting with anchors is recommended for extra safety.

What is the typical warranty and maintenance?

• Most suppliers offer a 10–15 year warranty depending on the resin system. FRP grating requires minimal maintenance—only periodic cleaning and checking for loose clips. No painting or rust treatment is needed.
