Fireproof Coating for Steel Structures for steel columns

Fireproof Coating for Steel Structures for Steel Columns

When you need to protect steel beams in dangerous places, you need a solution that works consistently in all kinds of weather. The cementitious recipe in our Fireproof Coating for Steel Structures for steel columns is made for industrial plants, tunnels, bridges, and other high-risk construction projects that could catch fire. It can fight fire for up to three hours, has a compression strength of 35MPa or more, won't crack, and will last for more than 15 years. This coating gives your steel beams the strong security they need. Henan Banggu Fire Technology Co., Ltd. has been making coatings for more than 30 years, so you can be sure that every job will be done well and get good technical help.

Why Steel Columns Need Specialized Fire Protection?

Steel supports are very important for supporting the weight of your buildings. Unprotected steel loses its strength and steadiness very quickly when it comes into contact with fire.

This problem is directly dealt with by our treatment. It makes a thick shield that keeps heat in and stops steel beams from heating up too quickly. This keeps your building's structure when there is a fire.

You have more than one defensive edge. The high-density recipe doesn't crack, even when heated up. The layer will stay stuck to steel surfaces for the life of the building because it has strong adhesion. The combination is made to work with the complicated shapes of steel frames and columns.

Technical Specifications

Key Performance Features

Fire Resistance

This Fireproof Coating for Steel Structures for steel columns rapidly expands when exposed to flames. It creates a carbonized insulation layer that slows heat transfer to the steel beneath. Your columns maintain load-bearing capacity longer, giving occupants more evacuation time and protecting property.

Environmentally Safe Formula

You don't have to compromise safety for performance. Our coating contains no harmful volatile substances and meets ISO 14001 Environmental Management System standards. It's safe for residential buildings, shopping malls, and factories—anywhere your projects take you.

Proven Durability

With compression strength exceeding 35MPa, this coating withstands the physical demands of construction and long-term service. The anti-cracking formulation ensures the protective layer remains intact for over 15 years. You get lasting protection without frequent maintenance.

Versatile Application

Whether you're working with steel beams, columns, trusses, or space frames, this coating adapts to complex surfaces. It can be applied by troweling or spraying, giving you flexibility based on project requirements and site conditions.

FAQ

Q1: What is intumescent tech?

A: Our coating foams and expands quickly under flames. Carbonisation forms a strong insulating layer that inhibits flames and heat. Your steel columns stay stable and reach your fire resistance rating due to slower temperature rise.

Q2: What are the application methods?

A: Spray, brush, or roll on. Spraying is efficient and smooth, thus we recommend it for wide areas. Method selection depends on project size and site factors.

Q3: How many square meters can one kilogram cover?

A: Coverage is estimated at 1.2-1.5 kg/m² per millimetre of thickness. The intended fire-resistant thickness for your fire resistance grade determines your coverage. For instance, 2.0-hour fire resistance needs 3.0–4.5mm thickness.​​​​​​​

Q4: Does the substrate need rust protection?

A: Yes, rust prevention is crucial. A well-prepared substrate guarantees good adherence and longevity. Coating works best on clean steel surfaces without corrosion, oil, or impurities.

Q5: Can topcoat be used?

A: Absolutely. Apply appropriate solvent- or water-based topcoats when the coating dries. This improves stain resistance and aesthetics without reducing fire resistance. Custom colours are possible, although white and light grey are standard.
