Gypra GRG column casings are designed solely for interior use and are manufactured from glass reinforced gypsum (GRG) to provide an excellent combination of strength and versatility, as well as ease of installation and fire resistance. Whilst they are normally specified as circles, as Gypra casings are produced from moulds, they can be manufactured to meet any individual specifications and project requirements, including square and rectangular profiles as well as virtually any bespoke shape.
Where a smooth finish is required for on-site painting, Gypra casings provide an excellent solution, whether they are part of our standard range or bespoke manufactured from special moulds to meet specific project demands. Integral brushed aluminium or stainless steel skirting collars are also available as an option to provide additional protection, durability and wear resistance. Gypra column casings are fire-resistant, achieving a Class ‘O’ fire propagation to BS476-6, and can be regarded as a non-combustible building component.
