Fireproof Coating for Steel Structures weather resistant

Fireproof Coating for Steel Structures Weather Resistant - Enterprise-Grade Fire Protection Solution

When you need to protect important steel structures in tough settings, you need a solution that is both fire-resistant and built to last. With a fire resistance of up to 2–6 hours, thermal conductivity of less than 0.12 W/(mK), and a service life of more than 9 years, our Fireproof Coating for Steel Structures weather resistant recipe provides enterprise-level security. Henan Banggu Fire Technology Co., Ltd. has been making coatings for more than 30 years. This intumescent coating quickly grows at high temperatures (up to 1100°C), creating a thick layer of carbonised insulation. As long as the bonded strength is at least 0.15 MPa and the compressive strength is at least 0.3 MPa, the security is good enough to meet ISO 9001, ISO 14001, and ISO 45001 standards.

Why Choose Our Weather-Resistant Steel Structure Fire Protection?

Fire Performance for Critical Applications

Your building is held together by steel beams, columns and struts. When there is a fire, you need a protection that can be used right away.

When our intumescent mixture comes in contact with flames, it quickly foams up. It turns into a tough, carbonised wall that stops heat from moving. This keeps the steel from breaking down during the important escape time.

Tested safety is given to you. Depending on the thickness of your product, fire resistance values range from 0.5 to 6 hours. Temperature resistance goes up to 1100°F, which is much higher than what a normal building fire would be.

Built to Last in Demanding Environments

When your project is going to be outside in bad weather or near the coast, weather protection is important.

For more than 9 years, the layer keeps its defensive qualities. Water doesn't get through—it didn't boil or peel after being exposed to water for 72 hours. This Fireproof Coating for Steel Structures is resistant to the elements and can withstand temperature changes from -5°C to 40°C.

Also, the bonding strength is very high (≥0.15 MPa), which means that the coating stays firmly attached to steel surfaces even when they are heated up.

Lightweight & Cost-Efficient Design

In structural engineering, every kilogram counts. Heavy coats add weight that isn't needed and raise the cost of the base.

Our thin-film technology gives you the best security with the least amount of weight. Coverage of 0.8 to 1.5 kg/m² theoretically cuts down on material use. Depending on the fire grade you need, the coating can be as thin as 3 mm or as thick as 50 mm.

You spend less on things. You cut down on the need for structure support. With faster application, you can speed up project timelines.

Environmentally Safe & Compliant

The things your workers use should be safe. Environmental rules are very strict, and your projects need to follow them.

The low-toxicity recipe doesn't have any volatile chemicals that are dangerous. The VOC level stays within the allowed ranges of 120g/L for water-based and 650g/L for solvent-based. The covering is safe for high-traffic places like shopping malls, office buildings, and public buildings once it has dried.

Our dedication to green making is shown by our ISO 14001 Environmental Management System approval.

Technical Specifications

Where You Can Apply This Coating?

Industrial & Commercial Buildings

Steel-framed warehouses, manufacturing facilities, and distribution centers require robust fire protection. Load-bearing beams and columns in these structures support heavy equipment and inventory.

High-Rise Construction

Multi-story office buildings and residential towers depend on steel frameworks. Fire codes mandate specific resistance ratings for different building heights and occupancies.

Public Infrastructure

Stadiums, gymnasiums, convention centers, and transportation hubs need both safety and aesthetic appeal. Our coating provides clean, professional finishes in multiple colors.

Bridge & Structural Steel

While primarily designed for indoor use, this Fireproof Coating for Steel Structures weather resistant formula works for covered or protected structural applications where steel needs fire and corrosion defense.

Application Made Simple

Surface Preparation

Clean steel surfaces thoroughly. Remove rust, oil, grease, and loose mill scale. Apply proper rust-preventive primer to bare steel—this step is essential for long-term adhesion.

Application Methods

Spraying works best for large areas. You get uniform coverage and smooth finishes quickly.

Brushing or rolling suits smaller sections, touch-ups, and detailed work.

Environmental Conditions

Apply when temperature stays between 5°C and 35°C. Relative humidity should remain below 85%. Avoid application during rain, fog, heavy dew, or high wind conditions.

Drying Time

Surface dries in approximately 0.5–1 hour. Full cure takes 12–24 hours. Wait at least 4 hours between coats (longer in cold weather).

FAQ

Q: What does "intumescent" signify for fire protection?

A: Fire immediately foams and extends the coating. It resists heat and flames with a strong carbonised insulation layer. Steel temperature rises slowly, limiting quick structural instability during flames. Load-bearing steel lasts long enough to fulfil your fire resistance rating.

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

A: Drying quicker, solvent-based coatings have improved adhesion, water resistance, and hardness. They fit interior tasks that need strength and weatherproofing.

A: Eco-friendly water-based solutions smell less. However, they dry slower and withstand water less.

Q: IS this coating regulatory-compliant?

A: Yes. National standard GB 14907-2018 "Fireproof Coatings for Steel Structures." Each batch has national fire protection product tests. Docs aid fire safety inspections and building code compliance.

Q: How much thickness do I need for different fire ratings?​​​​​​​

A: Reference values based on test reports:

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

Always refer to official test reports for project-specific requirements. Steel section factors and heating conditions affect actual thickness needs.

Q: Can I apply a decorative topcoat?

A: Absolutely. After the fire protection coating fully dries, you can apply compatible solvent-based or water-based topcoats. This doesn't affect fire resistance and enhances both appearance and stain resistance. Topcoats also add extra weather protection for demanding environments.
