FRP Grating Material Details & Composition
Composite Material in FRP Gratings
Composite materials used in FRP gratings are made by combining two or more different components that individually lack structural strength but together create a highly durable and load-bearing material ideal for industrial flooring and structural applications.
FRP / GRP Material (Fiberglass Reinforced Plastic)
Fibre Reinforced Plastic (FRP) / Glass Reinforced Plastic (GRP) is a high-performance composite material widely used in industrial FRP gratings. It consists of a polymer matrix reinforced with fibres such as fibreglass, carbon, or aramid, combined with resins like epoxy, vinyl ester, or polyester for enhanced strength and corrosion resistance.
Raw Materials Used in FRP Gratings
- Glass Fibres: Provide high tensile strength and stiffness, supporting heavy load-bearing applications.
- Resin Matrix: Binds fibres together and transfers load efficiently while offering chemical resistance.
- Additives: Improve properties like fire retardancy, UV resistance, anti-slip surface and electrical insulation.
Polyester Resin System for FRP Gratings
- Widely used resin for FRP gratings due to balanced mechanical, electrical and chemical properties.
- Can be modified for flame retardant and self-extinguishing industrial applications.
- Offers good resistance to mild acids, alkalis and moisture.
- Maximum operating temperature up to 80°C for standard industrial use.
Vinyl Ester Resin System (High Performance FRP)
- Combines advantages of polyester and epoxy resins for superior durability.
- Provides high strength and excellent resistance to strong acids and chemicals.
- Ideal for high-temperature and corrosive industrial environments.
- Maximum operating temperature ranges from 90°C to 150°C.
Pultrusion Process
Pultrusion is the process of pulling fibreglass reinforcements such as mats and
strands through a proprietary resin and heated die. The result is a specific complex profile that can
be cut to any length. This process offers speed and consistency making it the best method for
producing high-volume linear fiberglass products that require constant cross sections.
Pultrusion refers to pulling plastic raw material through a preformer. This
production method is particularly suitable for tubes, profiles etc. reinforced with continuous fibres,
involving pulling of impregnated fibres via preformers providing the form as, simultaneously, the
plastic is hardened with heat (thermoset) or cooled until solid (thermoplast).
Moulding Process
GRP/FRP Gratings are produced by wet moulding and hot curing in a heated mould. The reinforcement consists of continuous fibreglass rovings in alternatinglayers, so the loads are distributed evenly in all directions. Regularly Moulded GRP Gratings have a polyester resin matrix. Glass content is approximately 35%. standard colours are green, yellow or grey, other colours are available according to RAL.
Resin System For Gratings
| Resin Type | Resin Base | Description | Flame spread rating ASTM E84 |
|---|---|---|---|
| Type IFR | Isopthalic Polyester | Industrial Grade Corrosion resistance & fire retardant | Class 1, 25 or less |
| Type I | Isopthalic Polyester | Industrial Grade Corrosion resistance in acidic environment | Non fire retardant |
| Type V | Vinyl Ester | Superior Corrosion resistance & fire retardant | Class 1, 25 or less |
| Type P | Phenolic | Low smoke and superior fire retardant | Class 1, 5 or less |
