- Product Description
Fireproof Paint for Steel: Professional Fire Protection Solution for Steel Structures
Getting the right fire prevention device is the first step in keeping your steel infrastructure safe. It was made so that our fireproof paint for steel can protect steel beams, columns, and frames in harsh industrial and business settings. Henan Banggu Fire Technology Co., Ltd. has been making coatings for more than 30 years and this advanced intumescent coating keeps things from catching fire for up to three hours, can handle temperatures up to 1000℃, and keeps its Grade 1 adhesive. It dries quickly and is easy to apply. For projects that need both safety and speed, it provides solid fire protection at a low cost.
Why Choose Our Fireproof Paint for Steel?
During fire situations, your steel buildings are in grave danger. At high temperatures, steel loses its structural integrity if it is not properly protected. This can cause catastrophic breakdowns.
This problem is easily fixed by our special treatment. When it comes in contact with flames, it quickly grows to make a thick layer of carbonised protection. This shield stops heat from moving, which slows the rise in temperature in steel parts. Your building keeps its load-bearing ability for longer, which gives people more time to safely leave.
Fire Protection Performance
International fire safety standards are met, so you know you're safe. Depending on how thick it is applied, the covering protects against fire for 0.5 to 3 hours. It works well to keep steel from changing shape when it's very hot.
This option gives you the extra safety you need to protect steel beams in shopping malls, towers in office buildings, or trusses in factories.
Safe and Environmentally Responsible
The people on your team and in the building deserve safe goods. There are no dangerous volatile chemicals in our fireproof paint for steel, and it meets the standards of the ISO 14001 Environmental Management System.
The low-odor recipe makes sure that the working conditions are comfortable during application. Once it's dried, it's totally safe and can be used in high-traffic areas like factories, business spaces, and residential buildings.
Easy Application, Fast Results
When you work on projects, time is money. In just 0.5 to 1 hour, the surface of our covering hardens and is ready to use. You can spray it on, brush it on, or roll it on, based on the needs of your job.

The smooth finish only needs 0.8 to 1.5 kg/m² of material, which is a very small amount. This option is very light and doesn't add much weight to your steel buildings while protecting them fully.

FAQ
Q: What is intumescent fireproofing?

A: Fire rapidly foams and extends this covering, creating a dense carbonised insulating layer. Fire and heat are blocked by this barrier, delaying steel temperature growth. Your steel construction meets fire resistance standards during emergencies.
Q: What distinguishes solvent- and water-based versions?
A: The solvent-based variants dry quicker, have better adhesion, water resistance, and hardness. Indoor applications needing durability and weather resistance benefit from them.
Though slower to dry and less water-resistant, water-based variants are greener and odourless.
Q: Does this meet fire safety?
A: Our product is GB 14907-2018 "Fireproof Coatings for Steel Structures" compliant and contains national fire protection product test results. Suitable for fire safety assessments.
Q: How much thickness do I need for different fire ratings?

A: Reference values based on test reports:
- 0.5 hour rating ≈ 1.5mm thickness
- 1.0 hour rating ≈ 1.5–2.2mm thickness
- 1.5 hour rating ≈ 1.8–3.3mm thickness
- 2.0 hour rating ≈ 3.0–4.5mm thickness
Always refer to your specific test report for precise requirements.
Q: Can I use this coating outdoors?
A: No, this product is designed exclusively for indoor applications. For outdoor steel structures, we recommend our specialized outdoor intumescent or non-intumescent fire-retardant coating systems that include UV and weather-resistant layers.
