The GypSerraTM technology

special high-performance

GypSerraTM is made of special high-performance steel that undergoes stringent quality checks and controls to ensure correct and consistent base material for further profiling. The steel comes in rolled coils to maintain the proper thickness throughout its length. Quality checks ensure correct selection of material for strength and corrosion resistance. The steel sheet is work-hardened by passing it through a teethed roller with a patented serration design which gives a typical unique serration pattern on the surface. This serration pattern along with Gyproc Logo embossed on each component are the key identifiers of genuine GypSerraTM from Gyproc.

GypSerraTM metal components are manufactured with Patented Serration Technology (patent no: 325062). GypSerraTM is manufactured through a cold rolled pre-forming process that locally work-hardens the base material, and provides great strength to the false ceiling and drywall systems.
