GRP Grating – Compression Molded

KORDEK – COMPRESSION MOLDED FIBERGLASS GRATING

Kordek compression-molded Fiberglass Reinforced Plastic (FRP) offer the best available combination of strength, durability and ease of installation. The compression-molded grating system originated in 1971 by International Grating Inc. is the only system of it’s kind in the world.

KORDEK SQUARE-MESH GRATING

Kordek compression-molded, 1 1/2″ x 1 1/2″ square-mesh grating offers maximum design and installation versatility because bearing bars span in both directions Kordek square-mesh can be

PANEL WEIGHT & OPEN AREA

KS – 1510 100 lbs. per panel -60 % open Area
KS – 1515 160 lbs. per panel -60 % Open Area

STANDARD RESIN SYSTEM & COLOR

  • IFR – Premium grade polyester resin system with Class 1 fire retardancy, per ASTM E-84.
    Standard colors are yellow and green.
  • VFR – Vinylester resin system with Class 1 eire retardancy, per ASTM E-84.
    Standard color is orange.

STANDARD TOP SURFACES

  • Molded Raised Studs – integrally molded during compression-molding process to provide a non-slip surface.
  • Grip Top – aggregate applied as a second operation to provide an excellent non-slip surface.
  • Epoxy Grit – is bonded to the wide side bottom of the grating bar.

LOAD AND DEFLECTION DATA

The Load and Deflection Data provided in these tables are intended for guidance only, to help you determine the proper grating for your application. The use of different resin systems and surfaces can produce variations up to 15% in these values. Because the product will be used in environments and under operating conditions that are not within our control, we cannot guarantee the performance of the grating. FRP products have low modulus of elasticity but high tensile strength, therefore loads are generally limited to the allowable deflection determined by the end user. The following data are based on tests utilizing panels supported on two sides only. Additional stiffness can be achieved by using cross supports.
