There are conventional systems that can be deployed in protection against fire and especially in steel structures. One of them is the blanket and board system for security. Another method is the coatings done based on gypsum. Steel can also be coated by the use of an intumescent system of the layer. When it comes to blanks and the board’s policies, is applied basically for numerous reasons. Primarily, the design is useful in terms of cost, has properties of water resistance; it is a clean method.
Additionally, it can be applied with much ease in the members of the non-painted steel. Furthermore, it is a durable and robust system with decorative finishes that are compatible. Fire protection that is boarded is best suited for columns of steel and the regular shaped beams (Rockwell, 2017). Typically, the thickness of the board is dependent on the type of material.
Boards can be produced from different types of materials like calcium silicate, gypsum plaster or mineral fiberboard with resin or gypsum, and may contain lightweight fillers including vermiculite. The fire systems that are boarded are distinguished into two, for instance, the thin board and the heavyweight boards. The case of the lightweight boards is only applicable in cases where the aesthetic value is not valued. This is because they are not in any way compatible with decorative finishes (Pötzsch et al., 2018). The blanket system of protection is applicable where the policies of fire protection cannot cover the element of steel. Numerous irregularities in shape structure primarily cause the inconvenience. Another method of coating is the intumescent steel coating which resembles the materials that are used in painting. They are generally inactive in ambient temperature conditions. However, they become activated at higher temperatures ranging between 200 – 250 degrees Celsius. Upon its activation, there is the unleashing of chemical reaction that is complex that leads to severe swelling.
