Fireproofing paint for steel structures - a fireproofing solution worth investing in

Fireproofing paint for steel structures is evaluated as a solution to protect and increase the life of steel structures. Compared with other fireproof solutions, fireproof paint is also popular because of its low cost and high aesthetics. So what is fireproof paint for steel structure? What advantage does this passive fire protection method bring? Find out more in the article below.

Learn about fireproofing paint for steel structures: Features, mechanisms and benefits of using this paint

Steel is a material used in many constructions because of its light weight, ease of movement and solid structure. However, this material is quite fire resistant. Therefore, to protect buildings and factories, contractors should consider using more fireproofing paint for steel structures. This type of paint is the solution to help steel buildings increase their lifespan. The following content will help you understand more about fireproofing paint.

What is fireproofing paint for steel structure? The benefits of fireproofing paint

Fireproofing paint for steel structure is a product that is coated on a steel surface to prevent fire and reduce the risk of fire and explosion. This paint meets fire protection standards and is sensitive to temperature. When the temperature on the painted surface exceeds the allowable threshold, the paint layer will automatically swell to protect the steel structure. This type of paint also has the ability to reduce the flame temperature over time (depending on the type of paint).

Currently, this type of paint is widely used in workshops, factories, and large-scale constructions.

• Protect the surface of the steel material and the steel core from corrosion and ambient temperature.

• Increase the life of steel structures and limit the risk of rust.

• Slowing down the fire and explosion process, preserving the steel core inside.

• Avoid collapse of steel structure when fire occurs, affecting life.

• Fireproof paint for steel structures has a diverse color palette, helping to increase the aesthetics of the works.

• Limiting maintenance costs, replacing steel frames.

• Protect steel structures from deformation when exposed to high temperatures.

How does fireproofing paint for steel structures work?

This paint line can withstand temperatures higher than 1000 degrees Celsius. The paint has no toxic substances, so it is safe for human health. This paint is explosion-proof based on chemical reactions. Fireproofing paint for steel structure works according to the following mechanism:

• When the temperature is at 150 degrees Celsius, the paint layer begins to react and produce Phosphoric acid - an acid commonly used in fireproofing and anti-corrosion products.

• When the temperature is above 300 degrees Celsius, the paint film will give off non-flammable gases, forming layers of honeycomb-like foam with thermal insulation.

• When the temperature is above 500 degrees Celsius, the zinc borate and aluminum hydroxide components in the paint will combine to form a substance similar to ceramic, with good thermal insulation.

• At temperatures higher than carburization, the paint creates a layer that helps insulate the surface from the flame, helping to reduce heat and loss.

• In the first 3-4 hours, when the temperature is up to 1000 degrees Celsius, the paint helps the structures not to be deformed, giving the fire truck enough time to come to extinguish the fire.

What should be noted when using fireproofing paint for steel structure?

In order to achieve the highest efficiency of fireproofing paint, the constructor should not apply paint when the humidity in the air reaches 60-80%. To achieve the best adhesion, the contractor needs to clean the steel surface and use primer, not Alkyd-based anti-rust paint. It is not recommended to apply fireproofing paint to steel structures when it is raining because it will reduce the effectiveness of the paint against fire and corrosion.

In short, fireproofing paint for steel structure is a breakthrough and optimal fireproof and insulation product. Therefore, this paint line is applied in many large workshops and factories.
