OPEN MOLDED GRATING

KORPLEX – OPEN MOLDED GRATING

IGI molded fiberglass grating is one –piece, reinforced polyester or vinylester (FRP) grating, available in standard panels and size.

It is manufactured by interweaving continuous, thoroughly wetted, fiberglass strand with thermosetting resin systems. Standard panels are available in three resin systems, two top surface configurations, two panel sizes three standard grid patterns.

Typical applications include floor systems, walkways, work platforms, stairs, ramps, trench covers & catwalks, has been successfully used in many industries including food processing, beverage, chemical processing, water & waste water treatment, metal finishing, pulp / paper, transportation, pharmaceutical, textile, oil/ gas & mining / smelting/refining.

STANDARD RESIN SYSTEM & COLOR &lt ;>

Standard Korplex resin system are made from premium grade resins.

The three standard resin systems are:-

    • PFR– Polyester resin system with class 1 fire retardancy, as per ASTM E-84. Moderate corrosion resistance.
    • IFR Plus- Premium grade Isophthalic Polyester resin system with Class 1 fire retardancy, as per ASTM E-84.
    • PFR & IFR resin systems meet USDA standards for incidental food contact.

Available colors for PFR & IFR are green, yellow, dark grey & light grey.

  • VFR– Vinyl Ester resin system with class 1 fire retardancy, as per ASTM E-84. For maximum corrosion resistance IGI’s standard resin system specify VFR..
  • Available colors : Yellow orange & drack grey..

Other resin system and colors are available on special order. All Korplex resin system an ultraviolet (UV) inhibitor.

AVAILABLE TOP SURFACE

  • Grit top – Integral embedded silica sand to a nominal depth of 3/16”
  • Meniscus – Concave half-moon cross section
  • Applied Grit – Epoxy grit bonded to meniscus top panels.

LOAD & DEFLECTION DATA

The Load & Deflection Data provided in these table are intended guidelines only, to help you determine the proper grating size for your application. The use of different resin system and top surface options 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 olds are generally limited to the allowable deflection determined by the end user. The following data are based on the tests utilizing panels supported on two sides only. Additional stiffness can be achieved by using cross supports.
