LAF’s UL LISTED FIREPROOFING is used to diminish heat transfer from a HYDROCARBON FIRE into the concrete encasement and /or steel structure. It does this by increasing the time to reach the critical point where spalling or structural failure occurs.
Irrespective of the type of FIRE RESISTANT CONSTRUCTION that has been adopted, it is imperative that the system be sufficiently robust to withstand the intensity and velocity of the fire as well as, in the case of Jet Fire, direct flame impingement.
Concrete and Structural steel have quite specific chemical composition and mechanical properties, and which through design may be profiled into a specific shape, form or cross-section. The shape, size, composition, and strength, must follow stringent standards. The most common structural steel member is the I-beam. A very stiff member in respect of its own cross-sectional area and which comes in a large variety of depths and widths. There are also channels, T bars, equal and unequal angles as well as square, rectangular and circular hollow sections. Concrete elements are typically square or rectangular and there are minimum dimensions as well as corner details to better combat heat uptake and reduce spalling.
