Although sharing most of the features of molded GRP grating,
there are distinct differences which give pultruded grating a unique usage
base. The most important feature of pultruded GRP grating consists of the
fact that the glass to resin ratio is higher in the bearing bar direction,
therefore the span capacity of pultruded gratings is higher compared to
that of the molded grating. This reflects in a reduction of support structures
and lower costs.
Chemical resistance
On the basis of the use of premium grade, orthophthalic, Isophthalic polyester or vinyl ester systems and a surface veil our pultruded gratings offer superior corrosion resistance to variety of acids and caustics from the environment of light or moderately corrosive to extremely corrosive applications.

Light weight
At approximately a quarter of the weight of steel, our pultruded gratings
are much easier to handle, which reduces handling costs, allows for easier
access and maintenance.
Rigidity
Our pultruded grating possesses about 35% resin and 65% glass content(by
weight), giving it the very high strength to weight ratio. Load bearing
bar capacity can be tailored to the application by modifying the glass
content, fibre orientation, and combination of mat and fibreglass roving
reinforcement.
UV-protection
All Our pultruded gratings are added UV inhibitor into resin during process
and a polyester surface veil is applied for optimum protection from the
effects of weathering.
Fire Retardancy
Flame spread rating of class 1,25 or less, per ASTM E-84.
Additional benefits:
Non Slip
Light weight
Maintenance free
Non conductive (electric and thermal)
Uni driectional strength
High Imapct resisstance
Easily fabricated
Chemical and corrosion resistant
