Fire Protective Plasters On Structural Steel
By creating an insulation barrier between the heat source and the steel this prolongs the steel from reaching its failure temperature.
Although there are various products available on the market very dense materials (i.e. concrete) tend to spall with rapid temperature rise due to the naturally contained moisture which is transformed to steam during a fire creating pressure within the structure. Medium density material allows the steam to dissipate preventing spalling and providing a more effective barrier system.
Tekrok C is an advanced medium density fire protective plaster for structural steel that can be trowelled or spray applied. Tekrok C has excellent fire resistant properties. Terkok C is a very durable product that is excellent for outdoor application on structural steel. Tekrok C has been tested by the SABS in accordance with Petrochemical standards as well as NFPA 58 providing a fire rating of up to 120 minutes
Tekrok S is an economically proven vermiculite cement material for fire proofing of structural columns and beams in commercial buildings. Tekrok S is spray applied onto primed or unprimed steelwork. Terkok S provides a fire rating of up to 120 minute and complies with the requirements of the National Building Regulation 0400 Section T.
Tekrok TG is an advanced medium density fire protective plaster modified from Tekrok C through addition of chemical additives. Tekrok TG is used where material structural stability of structural steel is required. Tekrok TG is a very durable product and excellent for outdoor application. Tekrok TG has been tested by the SABS in accordance with Petrochemical standards as well as NFPA 58 providing a fire rating of up to 120 minutes.
