Specifications for FRP Gratings
- GRP/FRP Gratings are produced by wet moulding and hot curing in a heated mould.
- The reinforcement consists of continuous fibreglass rovings in alternating layers, 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.
Advantages of FRP Gratings
- Corrosion And Chemical Resistance.
- High Strength To Weight Ratio.
- Electric And Thermal Non Conductive.
- EMI/RFI Transparent.

Material Details
COMPOSITE MATERIAL
Composites are materials made up of at least two different component materials, neither of which is suitable for structural use on its own, but when combined, they form a sturdy and firm material.
FRP / GRP MATERIAL
Fibre Reinforced Plastic / Glass Fibre Reinforced Plastic is a composite material made of a polymer matrix reinforced with fibres. These fibres are typically fibreglass, carbon, or aramid, while the polymer is usually an epoxy, vinylester, or polyester thermosetting plastic.
RAW MATERIAL OF FRP
- Glass Fibres: Provide stiffness and resist tensile and compressive loads.
- Resin: Transfers load between fibres and bonds them together.
- Other Additives: Provide fire retardancy, electrical insulation, etc.
RESIN SYSTEM – Polyester
- Most commonly used; good mechanical, electrical, and chemical balance.
- Can be modified for flame retardancy or self-extinguishing behavior.
- Excellent resistance in weak acid/alkali environments.
- Max operating temp: 80°C (basic grade).
RESIN SYSTEM – Vinyl Esters (VE)
- Combines benefits of polyester and epoxy resins.
- High strength and excellent acid/alkali resistance at high temps.
- Good thermal and electrical insulation.
- Max operating temp: 90–150°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 |

Industrial Applications of FRP Gratings
FRP gratings are widely used across industrial and infrastructure sectors because of their corrosion resistance, lightweight strength, anti-slip surface and low maintenance performance.
Chemical & Process Industries
Industrial FRP gratings are installed in chemical plants and process industries where traditional steel gratings fail due to corrosion exposure. Fiberglass gratings provide excellent chemical resistance and long service life.
Wastewater Treatment Plants
FRP walkway gratings and trench covers are widely used in sewage and wastewater treatment facilities because they resist moisture, acids, gases and harsh environmental conditions.
Marine & Offshore Platforms
Marine and offshore industries require corrosion resistant flooring systems. Fiberglass reinforced plastic gratings resist saltwater corrosion while reducing maintenance and improving operational safety.
Power Plants & Refineries
Industrial FRP floor gratings improve worker safety with anti-slip surfaces, fire retardant properties and electrical insulation in power plants, refineries and heavy industrial environments.
Food Processing Industries
FRP gratings are suitable for food and beverage facilities because they are rust-free, hygienic, easy to clean and resistant to moisture and chemical cleaning agents.
