s 9 I j Mesh -> How to select grating When selecting grating, we suggest you to consider the following: * Environment « Loading « Impact We have to consider the environment including corrosion level, temprature etc, in which grating is going to be applied. Then we can choose the right resin System for the product. We also have to look at the load requirement at diffrent span. j Diff驩rent resin System available: * Ortho / PFR: Flame spread = 20 * ISO / IFR: flame spread = 15 sr Vinyl ester: Flame spread = I 5 * High Fire Retardand IFR: flame spread = 10 « High Fire Retardand VFR: flame spread = 10 « Phenolic: Flame spread = 0 « Food grade & Translucent Square mesh Rectangular Mesh Mini Mesh j Surface Concave top Gr/t top Smooth top j Covered grating Smooth top Grit top Patterned top j Color availble Standard stock color: Custom color is available upon request

FRP Molded Grating Molded Grating Process Molded grating is manufactured by laying continuous glass fibers in the mould in the direction of vertical and horizontal, and thoroughly wetted out with resin, layers by layers. When the weaving process is completed, the mould is heated to cure the panel. After curing, the panel is ejected from the mould. The standard panel would have meniscus (concave) top surface. Any process such as post applied grit could be bonded after as a secondary opration. This continuous process produces an intgral, one-piece panel, which offers excellent corrosion...

Molded Grating Application

Pultruded Grating Process Pultrusion is a continuous process using fiber reinforcements with thermosetting resin matri- Spcification of Pultruded Grating (in mm) Pre-selected reinforcement materials, such as fiberglass roving, mat, woven fabrics or stitched fabric, are drawn through a resin bath in which ail material is thoroughly impregnated with a liquid thermosetting resin. Typical resins include polyesters, vinyl esters and phenolics. The wet-out fiber is formed to the desired gom驩trie shape and pulled into a heated steel die. Once inside the die, the resin cure is initiated by...
