Fire Rated Box-Up for Structural Steel

When a fire protection system for a steel structure is selected, the essential question is how to maintain the temperature of steel for a specified time under a certain limit, called critical temperature. When the steel temperature does not exceed the critical temperature, the load-bearing capacity in the fire condition is maintained and deformations are limited. The fire resistance requirement follows from national legislation and depends on the type of building, and is typically expressed in classes like 30, 60, 90, 120, 180 or 240 minutes. In European standards, this is denoted as ‘R30’ , ‘R60’ , etc. The designation ‘R’ ensures the load-bearing capacity of the steel structure for the indicated time period, given in minutes.

Fire protective boards

Fire protection boards are typically mineral boards (i.e., made of calcium silicate or calcium sulphate) reinforced with fibers and fillers. Apart from offering fire protection, some boards have been further optimised for durability, in particular, resistance against humidity and freeze-thaw. A strong advantage of boards is that they are produced in the controlled environment of the factory, with strict tolerances for relevant properties including thickness.

The installation complexity of different board systems varies greatly. Whereas some boards do not offer much integrity during fire exposure and need extensive supporting constructions (metal rails, clips, screws or glue) and joint treatments (joint filler, joint bands or skimming compound) and often multiple layers, other boards are more resistant and can be directly staple-fixed around the steel section, with (wedge) noggins or, in the case of columns, just a simple box.

Promat boards are all in the latter category: the easiest and fastest to install, causing minimal interaction with other jobsite activities. No application times or waiting times for drying of glue, filler or compound and no need to install metal rails and clips. Moreover, Promat boards have excellent fire performance, which translates into single-layer protection for a wide range of situations. Only for more severe fire requirements, double layers may be needed. The installation of fewer board layers directly translates into a further major saving on installation time. Moreover, having a thinner board system will reduce the total weight of the fire protection system on the structure, and during the installation it will reduce the volume for transport, storage and installation
