Product Description

Protect Your Steel Infrastructure with Enterprise-Grade Fire Protection

To keep your steel buildings safe, you need a solution that you can count on and that works in all kinds of weather. Our Fireproof Coating for Steel Structures high temperature resistant protects very well, staying safe at temperatures up to 1150°F for more than 2.1 hours. To cover things, Henan Banggu Fire Technology Co., Ltd. has been around for over 30 years. When this intumescent coating comes into touch with flames, it quickly grows, making a thick layer of carbonised insulation that keeps the steel from warping and the structure's strength. These items are strong enough to be used in workplaces, public buildings, and big infrastructure projects because they have a service life of more than 10 years and meet all ISO standards (9001, 14001, and 45001).

What Makes This High Temperature Resistant Coating Different?

Intelligent Expansion Technology

It doesn't just sit there when there's a fire. What it does. The intumescent solution quickly foams up and grows, making a thick layer of carbonised steel between the flames and the steel parts. This active safety feature greatly slows the movement of heat, giving your building valuable time in an emergency.

Temperature Performance

Your steel buildings have to deal with problems in the real world. Our High Temperature Resistant Fireproof Coating for Steel Structures can withstand temperatures as high as 1150°C. You always get the same level of performance when it counts most, whether you're protecting load-bearing columns in factories or steel trusses in business buildings.

Lightweight Yet Powerful

Heavier finishes make your buildings carry more weight than they need to. Our thin-film technology gives you the most security for the least amount of weight. You won't have to worry about fire safety because you'll use less material, keep project costs low, and keep the structure working well.

Key Benefits You'll Appreciate

Fast-Drying Efficiency

Time is money on construction sites. Our quick-drying formula means shorter construction periods and faster project completion. Surface dry in just 0.5–1 hour, with full cure in 12–24 hours.

Professional Appearance

The buildings you build should look good as well as work well. You can pick from common colours like white and light grey, or you can ask for colours. The surface is smooth and clean, which makes it look better and provides security.

Flexible Application Methods

Our covering can be applied by spraying, brushing, or rolling, depending on how you like to work. Spraying is the most efficient way to finish big jobs quickly and perfectly.

Environmental Responsibility

We've formulated this Fireproof Coating for Steel Structures high temperature resistant with your health and the environment in mind. Low odor, minimal VOC emissions, and compliance with ISO 14001 Environmental Management standards mean you can apply it confidently in occupied spaces.

Where You Can Use It?

Our coating protects various steel structural components across multiple applications:

Fireproof Coating for Steel Structures high temperature resistant

Industrial Facilities: Manufacturing plants, warehouses, processing centers
Commercial Buildings: Shopping malls, office towers, hotels
Public Infrastructure: Stadiums, convention centers, transportation hubs
Specialized Structures: Steel columns, beams, trusses, and space frames

Note: This product is designed for indoor use only. For outdoor applications exceeding 5 years, additional UV and weather protection systems are required.

Application Guidelines

Environmental Requirements

FAQ

Q: What is "intumescent" fireproof coating?

Fireproof Coating for Steel Structures high temperature resistant

A: Fire rapidly foams and extends the covering, creating a dense carbonised insulating layer. This barrier inhibits flames and heat, decreasing steel temperature rise and preventing structural fatigue during fires.

Q:What distinguishes solvent-based and water-based versions?

A: Solvent-based coatings dry faster, have adhesion, water resistance, and hardness, making them excellent for weatherproof jobs. Though slower to dry and less water-resistant, water-based variants are greener and odourless.

Q: Which requirements does this coating meet?

A: National fire protection product test reports and national standard GB 14907-2018 "Fireproof Coatings for Steel Structures" make it appropriate for fire safety inspections.

Q: Should I rust-proof the substrate first?

A: Yes, substrate treatment matters. Rust prevention improves fireproof coating adherence and durability.

Fireproof Coating for Steel Structures high temperature resistant

Q: Is a decorative topcoat possible over this fireproof?

A: Most definitely. Compatible solvent- or water-based topcoats can be applied after drying. Improves stain resistance and aesthetics without reducing fire resistance.

Safety and Storage

During Application

Ensure proper ventilation in work areas
Strictly prohibit open flames, smoking, and static electricity sources
Provide appropriate fire extinguishing equipment
Workers must wear masks, goggles, and protective gloves

Storage Conditions

Store in cool, dry, well-ventilated areas at 5–45°C. Keep away from direct sunlight, high temperatures, and heat sources. Shelf life is 12 months for water-based and solvent-based versions, 6 months for cement-based formulations.

Note: Solvent-based versions are classified as flammable liquids (UN1263 Class 3) and must be transported according to hazardous materials regulations.
