TWS moulded gratings
polyester and glass laminate
The gratings were manufactured in a moulding process. The combination of glass fibres with thermosetting resin creates an extremely strong, homogeneous grating panel. These two materials complement each other giving TWS gratings excellent compressive and tensile strength. The gratings are designed for use in the harshest industrial and commercial environments and do not require time-consuming maintenance.
They are suitable for indoor or outdoor use. The carefully-selected resin type provides protection against chemical corrosion and the damaging effects of UV rays, as well as fire protection properties if required.
When removed from the mould, the walls of the grating have a naturally concave surface, which provides some anti-slip properties. The anti-slip properties of the gratings may be increased by adding a coating of alumina grains. The additional anti-slip coating also improves the service life of TWS gratings.
The relatively low weight of the product makes transport, handling and installation much easier than for metal gratings. Panels can be cut to size before delivery or on site using a tool fitted with a diamond blade. The cutting points should be protected with resin or polyurethane lacquer.
