Fire Retardant Coating for Steel Structures

 Protect Your Steel Structures with Enterprise-Grade Fire Safety

Our Fire Retardant Coating for Steel Structures has been shown to work well when you need to protect big steel structures from fire. This product, made by Henan Banggu Fire Protection Technology Co., Ltd., can fight fire for 0.5 to 3 hours for thin-type systems and for 2 to 6 hours for thick-type systems. Our coating protects steel beams, columns, and arches well, with a heat conductivity of ≤0.12 W/(m·K) and a bonding strength of ≥0.15 MPa. We have been making coatings for more than 30 years and are certified by ISO 9001, ISO 14001, and ISO 45001, so you can trust us to work with building contractors, distributors, and business buyers all over the world.

Why Choose Our Fire Protection Solution?

Fire Performance You Can Trust

When our intumescent layer is put near fires, it acts smartly. It quickly grows into a thick layer of carbonised insulation that stops heat from moving. This keeps your steel parts from getting to dangerously high temperatures where they lose their strength.

This important safety measure is needed to keep your building safe.

The covering does a good job of slowing down the burning process. During fire situations, steel buildings keep their ability to hold weight for longer. This gives people more time to safely leave the building.

Environmentally Safe and Compliant

To care about the world, you don't have to risk your life. There are no volatile, unhealthy chemicals in our mix. It meets the highest standards for guarding indoor areas around the world.

That thing is safe to use, and when it's dry, it doesn't smell bad. In places like shops, workplaces, homes, and offices, you can use it without worry.

There is proof that we follow ISO 14001 as an environmental management system. Less than 120g/L of VOC is present in water-based formulations, and less than 650g/L is present in solvent-based formulations. This level and this level are both allowed everywhere.

Fast Application, Quick Results

Time is important when making things. Our goods dry fast, which helps you keep up with your work.

The surface is dry after thirty minutes to an hour. The stiffening process is finished in 12 to 24 hours. You can put on the next coat after only 4 hours.

You have more choices when you can apply in more than one way. Spraying is the fastest and smoothest way to cover large areas. It's good to brush and roll on small areas or for touch-ups.

Lightweight Yet Powerful Protection

When you're dealing with building stress, thickness is important. Our thin-coating technology cuts down on the amount of material needed while still providing great fire protection.

Depending on the fire grade you need, coatings are usually between 3 and 50 mm thick. Coverage is thought to be between 1.2 and 1.5 kg/m² per mm of thickness.

This lightweight method keeps the extra structure load to a minimum. Your steel framework stays true to its form without adding extra weight that isn't necessary.

Technical Specifications at a Glance

Where You Can Apply Our Coating?

Our Fire Retardant Coating for Steel Structures protects various indoor load-bearing steel components:

• Steel columns supporting multi-story buildings
• Steel beams spanning large open spaces
• Steel trusses in industrial and commercial facilities
• Steel space frames in gymnasiums and stadiums

Common applications include:

• Industrial manufacturing plants
• Shopping malls and retail centers
• Office buildings and commercial towers
• Theaters and entertainment venues
• Residential high-rise structures
• Sports facilities and public venues

Note: This product is designed for indoor use only. For outdoor applications exceeding 5 years, you'll need a specialized UV and weather-resistant protection system.

Application Made Simple

Surface Preparation Requirements

Your steel substrate must be rust-prevented before coating. Clean surfaces ensure good adherence and durability.

Substrate temperature should be 3°C above dew point. This prevents moisture-related application difficulties.

Ideal Environmental Conditions

Apply coating when:

• Temperatures are 5–35°C.
• Keep relative humidity below 85%.
• Dry weather—avoid rain, fog, and dew.
• Quiet to moderate winds

Fire Resistance Ratings and Thickness Guide

Different fire protection levels require specific coating thicknesses:

• 0.5 hours ≈ 1.5 mm
• 1.0 hour ≈ 1.5–2.2 mm
• 1.5 hours ≈ 1.8–3.3 mm
• 2.0 hours ≈ 3.0–4.5 mm

Always refer to the test report for your specific project requirements.

Finishing Options

Standard colors include white and light gray. Custom colors are available upon request, though we don't recommend dark colors as they may affect fire resistance performance.

After the coating fully dries, you can apply a compatible topcoat. This enhances decorative appeal and stain resistance without compromising fire protection. Both solvent-based and water-based topcoats work well.

Complete Support Throughout Your Project

Our products meet regulatory requirements across the Middle East and Southeast Asia. You receive complete documentation including test reports, certificates of conformity, and factory inspection records.

Flexible Customization Options

OEM Manufacturing

We make things based on the methods and scientific details you give us. Quality control and strict production uniformity make sure that the results are the same from batch to batch.

ODM Development

Our team designs products, comes up with new recipes, and builds prototypes all by themselves. You can change the colours, logos, packing, and marking to get your product on the market quickly.

Both choices help you meet the needs of the project and the needs of the market quickly.

Storage and Transportation

Proper Storage Extends Shelf Life

Keep packages that haven't been opened in a cool, dry, and well-ventilated place. Keep the temperature of the storage area between –5°C and 40°C.

Stay out of bright sunlight, hot places, and things that are close to heat sources. The product will stay good for 12 months if these conditions are met.

Both water-based and solvent-based formulas can be kept for a year if they are handled properly. Options made of cement can be kept for 6 months.

Transportation Considerations

When temperatures go above 60°C, solvent-based formulas are considered dangerous liquids (UN1263). Transport in line with rules for dangerous goods.

The permits we have let us move things by land and sea. This makes sure that both local and foreign shipping works well and that logistics are optimised.

Products that are water-based or cement-based are safe for normal shipping.

FAQ

Q: What does "intumescent" mean for this coating?

A: In fire, the coating foams and expands quickly. It resists flames and heat with a strong carbonised insulation layer. Slowing steel temperature rise prevents your structure from losing stability during a fire. The expansion procedure meets your fire resistance requirements.

​​​​​​Q: What's the difference between solvent- and water-based formulations?

A: Solvent-based coatings dry quicker and stick better. They are harder and water-resistant. These are good for interior tasks that need strength, weather resistance, and rapid drying.

Water-based coatings pollute less and smell better. They dry slower and have worse water resistance than solvent-based solutions.

Q: Will this coating pass fire testing?

A: Yes, with correct paperwork and thickness. Test results, compliance certifications, and factory inspection records are needed. Inspectors assess product paperwork and appearance. They use a gauge to check dry film thickness for design compliance.

Q: Can I apply this coating outdoors?

A: Only indoor usage is recommended for this product. Outdoor applications require UV and weather protection, which this formulation lacks. Outdoor-specific intumescent or non-intumescent coatings with UV and weather protection are needed for steel constructions exposed for more than 5 years.

Q: Does the coating protect building inhabitants and workers?

A: Application of solvent-based formulations produces fumes. Proper ventilation and masks, goggles, and gloves for workers. Prevent smoking, open flames, and static electricity during application.

After curing and drying, the coating is safe. It's safe for malls, offices, and industries. The cured product passes national environmental regulations and includes no dangerous volatile chemicals.
