- Product Description
Steel Structure Fireproof Coating – Enterprise-Grade Fire Protection Solution
Henan Banggu's modern Steel Structure Fireproof Coating was made with over 30 years of experience making coatings. It will protect your steel structures. Our intumescent fire defence system keeps fires out for up to six hours and can handle temperatures of up to 1100°C. This coating has been certified by ISO 9001, ISO 14001, and ISO 45001, and it provides great thermal protection with a thermal conductivity of ≤0.12 W/(m·K) and a bonded strength of ≥0.15 MPa. Our layer is made for industrial plants, high-rise buildings, and bridge structures, and it works reliably and lasts longer than 10 years. Our answer offers strong fire safety, good looks, and low cost, whether you need thin-type or thick-type applications.
Why Choose Our Fireproof Coating for Steel Structures?
Proven Fire Resistance Performance
Every second counts when there is a fire. Our product quickly grows into a thick layer of carbonised protection. This barrier successfully slows the transfer of heat to steel parts, keeping the structure from collapsing and keeping its load-bearing capacity during the crucial escape time.
You get approved safety that meets the requirements of GB 14907-2018. Based on the needs of your project, our coating method offers fire resistance rates from 0.5 to 6 hours.
Environmentally Safe and Compliant
We care about your safety. Our covering doesn't have any volatile chemicals that are dangerous and doesn't smell bad. It is safe for the environment and passes international standards for VOC levels at ≤120g/L for water-based formulations and ≤650g/L for solvent-based formulations.
Our product is safe to use in shopping malls, office buildings, and home projects all over the world because it is CE approved and meets ISO 14001 standards.
Fast Application, Quick Results
In building, time is money. The top of our coating is dry in just 0.5 to 1 hour, and it's fully dried in 12 to 24 hours. It's easy to use because you can spray, brush, or roll it on.
The coating's thin thickness (3–50 mm) saves material while providing the best security. This means that the project will cost less and be finished faster for your tech teams.
Built on Three Decades of Expertise
Henan Banggu gets its covering technology from stars in the field that goes back more than 30 years. As the "Capital of Anti-Corrosion" in China, Changyuan City is where we are located. We blend old-fashioned knowledge with new technology.
Our RMB 20 million building takes advantage of good industry resources and easy access to transportation networks. This lets us provide uniform quality and dependable logistics for jobs in the United States and other countries.

FAQ
Q1: How does intumescent coating work?
A: Our intumescent coating foams and expands quickly in fire. It generates a thick carbonised insulating coating that prevents flames and heat, delaying steel temperature rise. This stops the steel structure from rapidly losing stability during fire, reaching your fire resistance rating.
Q2: How do solvent-based and water-based formulations differ?
A: Fast drying, great adhesion, water resistance, and hardness characterise solvent-based coatings. Indoor projects requiring strength and weather resistance benefit from them. Water-based coatings dry slowly and have poorer water resistance but are greener and odourless.
Q3: Does this coating meet international standards?
A: Yes. Our coating meets GB 14907-2018 "Fireproof Coatings for Steel Structures." It meets fire safety inspection and worldwide project criteria with comprehensive national fire protection product test results.
Q4: How much thickness do I need for different fire resistance ratings?

A: Reference values based on test reports:
- 0.5 hours ≈ 1.5mm
- 1.0 hour ≈ 1.5–2.2mm
- 1.5 hours ≈ 1.8–3.3mm
- 2.0 hours ≈ 3.0–4.5mm
Always refer to specific test reports for your project's exact requirements.
Q5: Can this coating be used for outdoor applications?
A: This product is designed for indoor use only. For outdoor applications exceeding 5 years of exposure, you'll need outdoor-specific intumescent or non-intumescent fire-retardant coatings with additional UV and weather-resistant protection layers.
