Manually Welded Heavy Duty Gratings are designed to meet the need for gratings subject to heavy rolling and static loads such as highways, plant floors, loading docks, inlet covers and airports. Since these conditions can range from light-duty forklifts to semi-trucks and trailers carrying maximum allowable highway loads, Heavy Duty gratings are manufactured in a wide variety of bar sizes and spacing.

BEARING BAR SELECTION: Once the bar spacing is selected, the bearing bar size must be specified based upon the anticipated load and the clear (unsupported) span to be served.

SERRATED SURFACE: Optional serrated bearing bars can be specified to enhance skid resistance. To maximize skid resistance, specify 100% Serrated grating. This Heavy Duty grating is manufactured with serrated bearing bars and serrated rectangular cross bars.

FRP Series Moulded Gratings manufactured in a open, heated mold system. Continues E -glass rivings system is placed in the molds and completely wetted out with resin.

Characteristics and properties of fibre glass

Resin and Glass fibers are the two components used in FRP Products. Resin is used to improve the chemical erosion resistant and Glass fibers which makes the product mechanically stronger.

Resin types

• Isophthalic
• Vinyl Ester

Glass fibre types

• Continuous unidirectional fibres
• Multidirectional mats with continuous fibres
• Synthetic surface veils

Due to less specific weight (1.75 kg/dm3 approx) installation, shifting of FRP products are very easy.

Fibre Glass Productsare manufactured using self-extinguishing low smoke emission resins to reduce risks in the event of fire. The various resins are mixed with halogen free additives, free from chlorinated and brominated compounds, etc.

Fibre Glass Products does not need any special maintenance even after many years of use.

Fibre glass product does not conduct electricity. For some specific applications the product needs to be conductive. In these cases a special additive is used in the resin to give the compound this characteristic.

Fibre glass product is a transparent material which does not interfere with electromagnetic waves, radio waves or radar.

In Pultrusion process load bars (I, T and HL) Shaped profiles are made by glass roving, matting & synthetic surface with a pulled simultaneously through a polyester or vinyl easter resin both and through heated steel die. I, T& HL shaped bearing bars are interlocked with solid rods or tubes. Pultruded gratings is good alternate compared to steel gratings due to its features like light weight, antifire, chemical & UV resistance, low maintenance cost etc.

Resin selection

Eurograte pultruded gratings are manufactured using two resin formulations that are suitable for most of the industrial applications. Both resin systems provide superior corrosion resistance compared to metal gratings.

Isophthalic resin system

This resin formulation provides a flame spread rating of less than 25 according to ASTM E84 norm. Gratings in this resin formulation are designed to be used in moderate corrosive environments where splashes and spills of harsh chemicals are likely. Standard color is yellow.

Vinyl ester resin system

This resin formulation provides a flame spread rating of less than 25 according to ASTM E84 norm. Gratings in this resin formulation are designed to be used in highly corrosive environments where the contact of harsh chemicals is frequent. Standard color is grey.

Ferrograte standard panel sizes are nominally 6 Mtr x 1 Mtr or 20ft (6 Mtr) x 3ft.

Panels available with load bearing bars of various depth 25, 30, 32, 35, 40, 45, 50, 60, 70mm & thickness of 3, 4, 4.5, 5 & 6mm.

Panels available with cross bars of various sizes like 5.4mm, 6mm & 8mm square twisted bars or plain round bars.

Panels available with serrated & plain type top surface.

Our most common pitches are 41mm x100mm & 30mm x100mm.

We can produce panels with special pitches like 41mmx50mm, 30mmx 50mm, 33mmx 100mm, 33mmx50mm, 33mmx38mm, 34mm x 100mm, 34mmx50mm, 34mm x 38mm etc.

Ferrograte standard panels available in hot dip galvanised finish or self colour finish.

Ferrograte offers tailor made grating panels as per fabrication drawings.

Our design office with latest cad software can design and prepare grating fabrication drawings to suit clients requirements.

Our design software directly connected to profile cutting machines, which can produce any kind of profiles in the gratings. After required profiling, edge can be fitted with frame bars or kick (toe) plates as per the clients requirement.

Our design team always available to suggest the required type of gratings as per your site conditions.
