Pendock Radius GRG casings are a highly versatile and adaptable solution for concealing interior columns and other structural elements, where a smooth joint-less surface is required or where painted finishes are specified.

Designed solely for interior use only, we have a range of standard sized circular moulds, which allow you to specify diameters from 200mm to 950mm and with lengths up to 3000mm. They can also be stacked to reach increased heights.

Although our GRG casings are commonly specified as circles, as they are moulded we can manufacture them to specific shapes and dimensions to meet the exact requirements of individual projects. The standard material thickness is 12mm and 15mm is also available as an option.

Our GRG casings are secured using countersunk mechanical fixings and an optional lightweight support framework. To achieve a seamless joint the two halves of the casing are butted together around the structural column with the heads of the fasteners and the small joint line concealed with a suitable filler prior to painting.

The palette of paint finishes available enables exact colour matching to integrate with a building’s interior design scheme, while the versatility of the GRG moulding allows increased design flexibility and freedom for architects and specifiers.
