Moulded Gratings
GOODWIN structural molded gratings profile shapes include equal angle, flat bars and cross sections etc. These structural shapes are used in a wide range of applications, offering a unique combination of chemical resistance, size stability, high strength, and thermal & electric non–conductivity. Isophthalic & Vinyl ester resins are available in Standard GOODWIN molded gratings as per different environments.
Fibre reinforcement in roving or chopped standard mat / roving forms are drawn through a resin bath to coat each fiber with a specially formulated resin mixture. The coated fibre is then drawn through a heated die. Cure of thermosetting resin is initiated by heat in the die and catalyst in the resin mixture. The rate of reaction is controlled by the heating and cooling zones in the die. The resulting high strength profile is cut to length, ready to use as it leaves the molding machine.

High Strength To Weight Ratio
The use of high strength E-glass roving reinforcement, molded to form a square mesh gratings panel, produces a strong flooring system suitable for safe pedestrian traffic on a wide range of spans.
Advantages
Molded grating provides an efficient and cost effective solution for flooring, walkways and decking areas requiring long-term performance in very aggressive and corrosive environments. Constructed from glass reinforced thermoset resins, our molded grating is an excellent choice to replace conventional steel and aluminum flooring systems in such aggressive environments.
Chemical & Corrosion Resistance
Composites molded fiberglass grating is manufactured using high strength fiberglass roving mat and a range of premium grade thermosetting resins. A high resin content of nominally 65%-70% provides durability and maintenance free performance in corrosive environments.
Solid Surface Gratings
Our Composites molded grating is available with an integral cover bonded to the top surface and finished with a tough quartz anti-slip surface.
Desgin
GRP construction profiles have a polyester resin matrix reaching a glass content of 65%. The profiles could be produced with vinyl ester or phenolic matrix or with self-extinguishing properties. Standard colors are grey, white or yellow
Sizes & Availability
The standard panel sizes of the GRP gratings are as per the international standard sizes of the mold, the sizes of the mold are 3660 mm length with 1220mm width. The gratings thickness and mesh opening will change upon the requirement. GRP Gratings can be fabricated (size and shape) upon the project specifications, but the maximum width & length will only be as mentioned above. If Gratings length or width is required above than the panel sizes, the gratings can be joined using stainless steel accessories with additional load support.
Surface
GRP construction profiles can additionally have a surface veil to provide resin rich surface. The profiles are UV-resistant and weather proof. GRP Profiles systems are available as preassembled modules.
