These days, there are diverse solutions available in the market for the fire protection of steel structures. Some of the major once are intumescent fire stopping paints, fire stopping sprays and Vermiculite Fireproofing Coating For Steel India. A majority of steel structures use intumescent paints and fire stopping sprays by 3 %. There are many other systems like cladding with fire-resistant sheets, partial pouring in concrete, the pouring of steel columns in concrete, the filling of columns with bricks made of foamed concrete. But the use of these methods is falling.
Intumescent Paints
The most widely-used system as Intumescent paints represents the cheapest fire protection alternative as well as has a thin layer. Apart from this they maintain the original look of steel structure and are very aesthetic. There are several benefits of these paints, and look at the major once below:
- The paint is applied in thin layers and is the most visually pleasing finish in fire protection. Designers prefer intumescent coatings because of their color range and versatility.
- This paint can complement any building design by boosting the look of any exposed steel. Besides, it lets more creative freedom for designers, particularly when used in big public structures.
- You can apply it to structural timber members as well.
Vermiculite For Steel Industry
Vermiculite is a single mineral used in the steel industry and is used as a molten covering for minimizing the oxidation of the metal. Vermiculite for Steel Industry maintains the temperature of melt for longer time and aids in easy sculling. There are many advantages to using it. For example- High energy saving, Negligible sculling during long casting cycles, Environment-friendly, high insulating properties, very cost-effective, No coating issues with stoppers and shadow tubes has no reaction with refractory lining. Other benefits include High sintering temperature (1260 degree Celsius), chemically inert, Low bulk density and excellent thermal insulation. However, there are some cons as well. For instance- It can be heavier than many other Fireproofing Coatings, may need considerable protection works before application and lesser delicate appearance than other fireproofing coatings
Fire Stopping Sprays
They are made of cement fibers, plaster, and vermiculite. Fire stopping sprays are mainly suitable for the building where aesthetics is not so vital, although the look may be modified with an optional final façade coat. The steel may be coated with a primer before application, however this is not needed, and whereas the binding layer of an acrylic copolymer is needed. The spray is applied by machine spraying as well as the layer of thickness ranges from between 10 and 70 mm. An extra reinforcing mesh is needed for a larger layer of thickness. The key advantages of fire stopping sprays are good sound absorption and low price. These sprays can reach a fire resistance of up to R 240.
