Fireproof Coating for Steel Structures anti-corrosion

 Protecting Your Steel Investment with Advanced Fire and Corrosion Defense

When you need to protect steel buildings, you need more than just simple coverage. Henan Banggu's Fireproof Coating for Steel Structures anti-corrosion provides two levels of security: it resists fire and rust at the same time. Our solution has been manufactured for more than 30 years and has a fire protection grade of 0.5 to 3 hours. It also has a bonding strength of 0.15 MPa or less and a thermal conductivity of 0.12 W/(m·K). Our products are approved by ISO 9001, ISO 14001, and ISO 45001, and their water-based versions have VOC content of less than 120g/L. This makes sure that your project meets international environmental standards without sacrificing performance.

Why Choose Our Steel Structure Protection System?

Fire and Corrosion Performance

Fire and rust are two major threats to your steel structures. Our covering takes care of both at the same time.

The intumescent formula quickly spreads to form a thick carbonised layer of insulation when it comes into contact with flames. This barrier stops heat from moving quickly, keeping steel from getting to dangerously high temperatures that would destroy the structure.

The anti-corrosion qualities protect against water, chemicals, and damage to the environment. You get assets that last longer and cost less to maintain.

Engineered for Real-World Applications

We made this system so that it is easy to setup and will last for a long time.

Quick Application Process

• Time for surface to dry: half an hour to an hour
• Twelve to twenty-four hours for full recovery
• Spraying, brushing, or rolling are all different ways to apply it.

Lightweight Protection

A covering that is only 3–50 mm thick adds little to the structure's weight while protecting it completely. Your steel supports, beams, and trusses meet the requirements of the plan.

Aesthetic Flexibility

It comes in white and light grey, but you can ask for other colours too. The finish is smooth, so it looks good in business, industrial, and domestic settings.

Proven Compliance and Certification

Your projects need proof of compliance. Our Fireproof Coating for Steel Structures anti-corrosion complies with GB 14907-2018 norms and is fully certified.

• National fire protection product certification
• ISO management systems for quality, the environment, and safety
• For foreign sales, CE certification
• Fill out test records for checks of fire safety

You are given all the paperwork you need to get governmental permission and project acceptance.

Application Guidelines

Substrate Preparation

Proper surface preparation ensures optimal adhesion and performance.

Clean steel surfaces thoroughly to remove oil, dirt, and loose mill scale. Apply rust prevention treatment before coating application. The substrate temperature must remain 3°C above dew point minimum.

Environmental Requirements

Apply under controlled conditions:

• Temperature: 5–35°C
• Relative humidity: ≤85%
• Avoid application during rain, fog, dew, or high winds

Coverage Calculation

Calculate your material requirements based on desired fire resistance:

• 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

Theoretical coverage: approximately 1.2–1.5 kg/m² per mm thickness.

FAQ

Q: How does intumescent coating protect steel structures?

A: The coating immediately foams and expands to produce a dense carbonised insulating layer that prevents flames and heat when exposed to fire. Slowing steel temperature increase ensures fire stability and fire resistance rating.

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

A: Fast drying, excellent adhesion, water resistance, and high hardness make solvent-based versions perfect for applications that need strength and weather resistance. Water-based formulations are greener, smell less, dry slower, and have less water resistance.

Q: Can this fireproof coating have a beautiful topcoat?

A: Yes. Apply appropriate solvent- or water-based topcoats after drying. This improves stain resistance and aesthetics without reducing fire resistance.

Q: Do I need rust protection before applying?

A: Yes, substrate needs rust protection. This optimises coating adherence and corrosion protection.​​​​​​​

Q; How can I ensure the coating passes fire safety inspection?

A: Test reports, compliance certifications, and factory inspection records should be thorough. Use a thickness gauge to check application thickness. Smooth surfaces without blisters, splits, or peeling should be visible. The coating usually passes fire safety examinations when properly applied and documented.
