Application of Fireproof Paint in Protecting Steel Structures

In the field of modern construction, protecting steel structures from the risk of fire and explosion is extremely important. One of the most effective solutions to protect steel structures is to use fireproof paint. This article will delve into the application of fireproof paint in protecting steel structures, helping you better understand the importance and benefits of using this product.

Steel Structure Protection Solution

1. Overview of Fireproof Paint

1.1. What is Fireproof Paint?

Fireproof paint is a special type of paint designed to protect the surface of materials from the destruction of fire. When exposed to high temperatures, fireproof paint will react to create an insulating layer, preventing fire from directly contacting the material, thereby minimizing damage caused by fire.

1.2. How Fireproof Paint Works

Fireproof paint works based on the principle of chemical reactions when exposed to high temperatures. When the ambient temperature increases, the chemical components in the paint will react to create an insulating layer, preventing the spread of fire. This helps protect the steel structure from losing strength due to high temperatures.

1.3. Types of Fireproof Paint

There are many different types of fireproof paint, including:

Water-based intumescent coatings: Environmentally friendly and easy to apply.
Solvent-based intumescent coatings: High fire resistance, often used for steel structures in harsh conditions.

2. Applications of Fireproof Paint in Steel Structure Protection

2.1. Protection of Steel Structures in High-Rise Buildings

In high-rise buildings, steel structures play an important role in bearing loads and maintaining the stability of the building. The use of fireproof paint helps protect steel structures from high temperatures, preventing the risk of collapse due to fire.

2.2. Protection of Steel Structures in Industrial Factories

Industrial factories often contain many flammable materials, so protecting steel structures from fire is extremely important. Fireproof paint helps increase the heat resistance of steel structures, protecting the safety of factories and workers.

2.3. Protecting Steel Structures in Civil Works

In addition to high-rise buildings and industrial factories, fireproof paint is also widely used in civil works such as shopping malls, hospitals, and schools. Protecting steel structures in these works not only ensures the safety of the works but also protects people’s lives.

3. Benefits of Using Fireproof Paint

3.1. Enhance the Heat Resistance of Steel Structures

Fireproof paint helps enhance the heat resistance of steel structures, preventing the reduction of strength due to high temperatures. This helps maintain the stability of the structure in the event of a fire.

3.2. Minimize Damage Caused by Fire

Using fireproof paint helps minimize damage caused by fires, protecting property and people’s lives. The insulation layer created by fireproof paint helps prevent the spread of fire, helping to control and extinguish fires effectively.

3.3. Meeting Fire Safety Standards

Fireproof paint helps the project meet international fire safety standards, ensuring safety for users and minimizing legal risks for investors.

4. International Standards Related to Fireproof Paint

4.1. NFPA Standards

NFPA (National Fire Protection Association) is an American non-profit organization that provides fire safety standards. Some standards related to fireproof paint include:

• NFPA 251: Test method for fire resistance of building materials.
• NFPA 703: Standard for fireproof paint and fireproof materials.

4.2. ISO Standards

ISO (International Organization for Standardization) provides international standards in many fields, including fire protection. Some ISO standards related to fireproof paint include:

• ISO 834: Fire resistance test of building components.
• ISO 12944: Protection of steel structures by anti-corrosion and fireproof paint.

4.3. EN Standards

EN (European Norms) is a European standard, widely applied in countries of the European Union. Some EN standards related to fireproof paint include:

• EN 13501: Classification of fire resistance properties of building products and components.
• EN 13381: Test method for fire resistance of steel structures protected by fireproof paint.

5. Fireproof Paint Application Process

5.1. Surface Preparation

Before applying fireproof paint, the steel structure surface must be cleaned and free of dirt, grease and other impurities. This helps the paint adhere better and achieve the highest fireproofing efficiency.

5.2. Primer Application

The primer helps increase the adhesion of the fireproof paint to the steel structure surface. The primer must be applied evenly and thinly, ensuring that there are no holes or uncovered areas.

5.3. Fireproof Paint Application

The fireproof paint must be applied evenly and with sufficient thickness according to the manufacturer’s recommendations. The thickness of the fireproof paint determines the heat resistance and protection time of the steel structure when exposed to fire.

5.4. Inspection and Maintenance

After construction, it is necessary to check the thickness and quality of the fireproof paint. Periodic maintenance helps maintain the fireproof effect of the paint and prolong the life of the steel structure.

6. Fireproof Coating and Steel Structure Protection Solutions

In addition to fireproof paint solutions, there is currently a long-term solution suitable for more difficult-to-access locations, which is the steel structure – fireproof column protection solution.

The steel structure – fireproof column protection solution uses KH Shield insulation panels that meet the test standards of “fireproof efficiency up to 120 minutes”, meeting the latest regulations in QCVN 06:2022/BXD standards. This is also one of the solutions being used by many businesses not only because it meets fire prevention standards but also is a “long-lasting” solution, “saving long-term costs” to help the project “sustainable” over time.
