Moulded GRP-grating - concave

The concave garting type is origin of the moulded gratings. During the heating of the gratings a concave surface is formed on the surface of the bars. This results in a very good slip-resistance. This grating achieve the serration class R13. 

GRP-gratings with a concave surface are used in areas where good chemical and weather resistance is required.

Characteristics

  • high corrosion and weather resistance
  • high chemical resistance
  • hygienic and resistant to bacteria
  • the gratings are loadbearing in the direction of the supporting rods and the crossbars
  • does not conduct electricity
  • low thermal diffusivity
  • Anti-slip up to R13
  • relatively low dead weight
  • simple and quick on-site assemply
  • high levels of comfort for walking and standing

The gratings available from stock are manufactured on the basis of a high-quality isopthalic resin and are available in grey similar to RAL7035. 

1 only in yellow similar to RAL1003 
2 aslo available in yellow similar to RAL1003 
3 also available in vinylester resin version in grey similar to RAL7042

The chemical resistance of the grating is determined by the resin used. The following resin versions are possible:  

Orthophal resin: medium chemical resistance
Isophtalic resin: good chemical resistance
Vinylester resin: very good chemical resistance
