intumescent fireproof coating

Intumescent Fireproof Coating – Professional Fire Protection for Steel Structures

When a fire threatens your steel building, you need quick and effective defence. Our intumescent fireproof coating has an expansion ratio of 20:1 and a fire durability of 1.5 hours, which is enterprise-grade. This advanced coating has been tested to work in temperatures as high as 1200℃. When heated, it expands quickly to form a thick layer of carbonised insulation. Henan Banggu Fire Technology Co., Ltd. has been making coatings for over 30 years and has a VOC content of less than 100g/L and a GB 8624-2012 Class A non-combustible grade, so you can be sure that they will protect you.

What Makes Our Intumescent Fire Protection Stand Out?

It's not easy to keep steel buildings from catching fire. These issues are directly addressed by our treatment.

When the product is put near fires, it turns into a thick layer of carbon foam. This extra layer does a good job of keeping your steel walls and beams warm. You'll love how well it stands up to heat and how well it sticks to things, keeping the safety in place.

It is easy to use by spraying or brushing it on. You can save time on building because the formula dries quickly. The surface is easy to level for a professional look.

A non-toxic recipe means that your team will be safer during installation. High-rises, workplaces, and public buildings can all use the system both indoors and outdoors.

Comprehensive Technical Assistance

Before purchase, you receive free product selection consultation and technical documentation. During construction, our team provides 24/7 remote guidance. After completion, we assist with acceptance documentation and fire safety inspections.

Application Recommendations

Ideal For:

• Steel beams and columns in high-rise buildings
• Factory workshop steel frameworks
• Public building structural steel
• Indoor protected environments

Construction Conditions:

• Apply at +5~40°C ambient temperature
• Relative humidity ≤85%
• Substrate temperature ≥3°C above dew point

Important Notes:

Indoor applications lack UV and weather resistance. For outdoor use exceeding 5 years, you need additional UV-resistant and weatherproof finish coatings. This protects the intumescent fireproof coating from environmental degradation.

Store between 5–45°C in dry conditions. Water-based and cement-based formulas are non-hazardous. Solvent-based versions are flammable above 60°C (UN1263 Class 3).

Cost-Effective Protection With Long-Term Value

Thin coating thickness reduces material consumption without compromising performance. You achieve competitive project costs while meeting fire safety requirements.

The lightweight structure adds minimal load to your building frame. This matters for weight-sensitive engineering applications.

Multiple color options and smooth finish provide decorative appeal. Your protected structures look professional and clean.

Fast drying accelerates project timelines. You complete installations efficiently and move to the next phase quickly.

Who Benefits Most From Our Solution?

Engineering Contractors: You need reliable products with consistent batch quality and technical support documentation for project approvals.

International Distributors: Our flexible OEM services and export certifications help you serve diverse markets confidently.

Commercial Project Owners: You receive cost-optimized fire protection solutions that balance performance, compliance, and budget requirements.

FAQ

Q1: What is fireproof coating and why is it important?

A: Fireproof coating is functional and fire-resistant. It creates a heat-insulating and oxygen-isolating layer on buildings, steel, and wood during fires. Slowing substrate ignition and damage rates allows for escape and rescue while decreasing fire spread and property destruction.

Q2: What are the changes in fire ratings?​​​​​​​

A: Indoor ultra-thin, thin, and thick steel structure fireproof coatings are classified by GB 14907-2018 as NCB, NB, and NH, with fire resistance from 0.5 to 3 hours. A1, A2, B, C, D, E, and F are EN 13501-1 ratings internationally. Better heat insulation, longer resistance periods, and high-risk appropriateness are available in higher classes.

Q3: Is application thickness necessary?

A: Thicker isn't always better—fire rating, coating type, and substrate requirements must meet. For 0.5-1 hour resistance, ultra-thin steel structural coatings need 0.3-0.8mm. 2-3 hour ratings for thick coatings require 10-50mm. Too thin fails fire requirements; too thick costs more and cracks.

Q4: Can fireproof coating be mixed with others?

A: Yes, but in order and compatible. Let fireproof coating cure before adding latex or fluorocarbon paint. Ensure the decorative coating won't react chemically or affect fire performance. Testing tiny areas before full-scale application.

Q5: Are exported goods required to fulfil international standards?

A: Absolutely. European, US, and Southeast Asian fire standards apply to exported coatings. Quality certificates, product testing reports, customs documents, and sometimes origin certificates are needed. Follow local environmental and safety laws.
