Description

PT. Graha Adhi Jaya Abadi, as the manufacturer of Dura-Gritz®  FRP gratings are
manufactured by open molding. Molded gratings are available in a variety of stock panel
sizes (i.e. 1m x 3m  & 1.22m x 3.66m,  for 38mm & 25mm deep, 38mm square mesh gratings).
The designer should consider these sizes at the early stages of structure layout to efficiently
utilize the material and minimize installation costs. Molded gratings are available in a variety
of resin systems and colors to meet specific project requirements. Detailed descriptions of
the resin systems available are included in the Dura-Gritz® Molded Product brochures.

Advantages
Corrosion Resistant
FRP products are known for their ability to provide corrosion resistance in
the environments with serious corrosion issues.

Low Maintenance
The durability and corrosion resistance are reduced the need for heavy
maintenance.

Anti Slipping
Steel becomes slippery when oily or wet, but Dura-Gritz® gratings have a
higher friction factor and remain safe even when wet.

Low Installation Cost

Dura-Gritz® only need bolts and clips for installation. This product can be
quickly cut and also we only need ordinary hand tools for cutting.

High Strength
Dura-Gritz® can be designed for high loads capacity.

Lightweight
FRP’s weight is lighter than steel (1/4 weight of steel).

Electrically and Thermally Non-Conductive

Dura-Gritz® FRP is electrically non-conductive leading to increased
safety compared to conductive materials (i.e., metal).

Fire Retardant
Dura-Gritz® provides option of Fire Retardant need, products are engi-
neered to have a flame spread of Class#1 & Class#3 in accordance with
ASTM E-84.

Long Service Life

Dura-Gritz® provides outstanding durability and corrosion resistance in de-
manding applications.

Impact Resistance
Dura-Gritz® can withstand major impacts with negligible damage. Dura-
Gritz® offers extremely durable gratings to satisfy even the most stringent
impact requirements.

UV Resistant
Dura-Gritz® are formulated for maximum UV resistance.
