Grating, Channel,
Ladder & Trench Cover
Yeung's provides two basic types of fiberglass-reinforced-plastic
(FRP) gratings: Compression °Vmolded (square mesh and rectangular mesh)
and pultruded. Each type provides the fundamental advantages that
make GRP a better investment than steel for most applications:
Maintenance free
Lightweight, easy to
install
Doesn't fatigue or
creep, stays flat for safe walking
Nonconducting a nonsparking
(high-conductance,
anti-static
grating is available
In addition, pultruded gratings provide a high degree of strength
and corrosion-resistance not found in conventional gratings.
The primary considerations that affect grating selection are:
Load/Deflection:
This is normally the starting point for grating selection. The type
of grating (rectangular-mesh or square mesh) interrelates with the
layout of the support structure because of the difference in span
directions.
Chemical Compatibility:
Yeung's gratings offer excellent corrosion resistance within the
capability of the specific resin system used. Resin systems, however,
have different chemical compatibilities.
Fire °V Retardance:
Fire-retardance is a function of the resin system used for the grating.
Special Considerations:
There are options available on special colours, resin systems and
non-skid surfaces.
