CONSTRUCTION TECHNOLOGY 2
Introduction
Structural steel is a group of material which is shaped with a precise cross-
section and quantified standards of métier. It is observed that structural
steel can be recycled and effective reused material in the world. Steel
construction fire defense techniques are mainly developed to defend the
construction from passion for a quantified amount of period (Adewale, et al.,
2013). The purpose of this research is to examine and review numerous fire
protection methods for protecting structural steel. It is argued that fire
defense methods can be divided into two parts including active and passive
techniques. This research will cover five fire defense approaches for
structural steel and review their working process, effectiveness, and
associated costs.
Fire protection methods for structural steel
There are major five methods developed for protecting structural steels
from the fire which are described below:
Boards and blanket fire protection process
It is an effective process that has the potential to control and manage risks
in the structural steels. This type of method is mainly utilized due to several
reasons including cost-effective, reliable, and rainproof may be useful to
non-painted strengthen memberships (Carosio, et al., 2015). The below
figure shows the process of boards and blanket fire protection:

Such kind of fire protection process is more strong and durable but also
helpful for handling the other issues that impact on the performance of the
structural steel.
The width of the panel is reliant on the physical type utilized for board
manufacture and the stated fire score required. It is argued that boards may
be produced from various kinds of materials including mineral fiberboard,
calcium silicate, and gypsum plaster and so on. Moreover, the board fire
defense scheme is categorized into various types including heavyweight and
frivolous panels (Franssen, and Real, 2012). In terms of effectiveness
boarded fire protection is more effective and reliable by which it can be
used in the reduction of fire protection issues in the structural steel. It is
examined that this type of methodology is less expensive in terms of
development and implement due to which many consumers are moving
towards boarded fire protection. The board fire defense scheme is able of
fighting passion for a supreme of 4 hours. Moreover, it can be applied for a
steel factor that may not be endangered by panel fire defense due to
indiscretion in the shapes including truss memberships.
Intumescent coating steel structure
It is similar to canvas material which is sedentary at ambient infection but it
would activate at a larger temperature including the range of 200 to 250
