In using Superfrp™ FRP grating, the principle is similar
to that of metal grating, but the flexural modulus of elasticity
of reinforced fiberglass bars is lower than that of steel. As a
result, the allowable deflection has to be taken into consideration.
The style of installation for Superfrp™ FRP grating can be
classified as secure installation, standard installation and 1%
Fixed Installation: Deflection : Span =1:180
Standard Installation: Deflection : Span =1:120
1% deflection installation: Deflection : Span =1:100
The data of load capacity provided by us comes from testing on
the basis of 1% deflection, it is also the heaviest load suggested
by us. The data, which is on the basis of secure installation or
standard installation, can be calculated as per the following formula
and the load data on the basis of 1% deflection.
Deflection of Grating = (Actual Load / Load on the basis of 1%
deflection) * 1% deflection.
Unknown Load = (Known Span2 / Span2 of Unknown Load) * Load of Known
Deflection of Covered Grating = Deflection of Grating * High3 of
Grating / (High of Grating + High of Covered plate)3
The above formula are based on experience, the result may not completely
accurate, but it can be used as refernece. Actual loading is heavier
than the calculation.
Tools of Installation:
Superfrp™ FRP grating can be cut at work-site by china disc
or emery disc, even the normal saw can be used. It is suggested
that to use water when cutting to avoid dusty. Meanwhile other safety
measures should be taken, such as gloves, protect glass and gauze
mask etc. should be put on.
Support and Connect:
All sides of Superfrp™ FRP grating should have support, and
the support should be at least 40mm width. The clip must be used
in the middle of 900~1800mm. Minimum four clips per side is required
for full size panels. Support has to be used under the joint of
two grating products.“M” and “L” clips are
used as connector between grating and framework. “C”
clip connects two pieces grating. Clips are sold as sets consisting
of clip, bolt, nut and washers. They are all made from stainless
If the FRP grating should be installed highly, we can supply the
Specially designed legs for 1-1/2" deep, 1.5" ¡Á1.5"square
mesh molded grating are manufactured to provide sturdy support for
elevated flooring. All fixed-height and adjustable legs support
flooring for heights up to 60 inches. (Cross bracing is required
for flooring elevated more than 24 inches.)
A:FIXED-HEIGHT LEGS /SINGLE HEAD - For supporting grating up to
60" above level concrete floor.
B:FIXED-HEIGHT LEGS /DOUBLE HEADS - For connecting adjoining panels.
C:ADJUSTABLE-HEIGHT MINI LEGS - For raising grating 2-3/4"
to 9" above uneven concrete floor.
D:ADJUSTABLE-HEIGHT LEGS /SINGLE HEAD - For uneven floors designed
to be screw-adjusted from atop the elevated floor.
E:ADJUSTABLE-HEIGHT LEGS /DOUBLE HEADS - For joining and supporting
panels above non-level concrete floor.
