Exterior Fireproof Coating for Outdoor Steel & Building Protection

To keep outdoor buildings safe from fire risks, you need more than just regular protection. You need an exterior fireproof coating that is made to work in real life. The outdoor fireproof coating from Henan Banggu Fire Technology is resistant to fire for 1.5 hours, works well in grade 1 weather, and lasts for more than 8 years. With over 30 years of experience making coatings and production that is ISO 9001 certified, our answer protects steel structures, bridges, roofs, and public buildings in all kinds of weather by blocking UV rays, keeping them dry, and slowing down the ageing process.

Why Outdoor Fire Protection Demands Specialized Solutions?

The things you put outside have special needs that home coatings just can't handle.

Rain and UV rays. Changes in temperature. Changes in humidity.

Standard fire-resistant goods fail within months of being put through these tests. Because of this, our product has parts that can withstand the weather and were designed to work outside. Formulations made for indoor use only focus on flame resistance. Our outdoor choice keeps its fire resistance while also being resistant to damage from the weather.

As a result? Strong protection that doesn't crack, peel, or stop working after one season.

Technical Specifications That Matter

Four Key Advantages for Your Projects

1. Fire Resistance Performance

When the flames hit, our coating quickly expands into a dense carbonised heat insulating layer. This barrier inhibits the heating of the substrate, safeguarding the steel beams, concrete surfaces and structural parts. You’ll gain consistent adherence to international fire safety codes—essential for export projects and multi-country engineering work.

2. Built to Last Outdoors

Normal coatings get destroyed by UV deterioration after 1-2 years. Our recipe also contains specialised UV stabilisers and anti-aging chemicals that preserve integrity for over 8 years. Whether your construction is subject to desert sun or coastal humidity, protection is universal.

3. Chemistry with an environmental conscience

Our exterior fireproof coating complies with stringent global environmental laws with VOC concentration of 100g/L and ISO 14001 Environmental Management certification. Thanks to its non-toxic recipe, it’s safe for the applicators and the people who occupy the building, no dangerous volatile compounds, no trade-offs.

4. Quality & Compliance Certification

We are ISO 9001, ISO 14001 and ISO 45001 certified and CE marked for European markets. Our solutions meet the Middle Eastern and Southeast Asian regulatory requirements, giving you paperwork confidence for cross-border projects.

Application Versatility

This coating adapts to multiple outdoor scenarios:

• Steel structures (warehouses, factories, bridges)
• Building exteriors (walls, columns, facades)
• Roofing systems (metal and concrete)
• Public infrastructure (tunnels, stations, facilities)
• Petrochemical installations (tanks, pipelines)

Application methods include spraying and rolling, accommodating various construction conditions and substrate geometries.

Professional Support Throughout Your Project

We provide comprehensive technical assistance across three phases:

Before Purchase: Free product selection consultation, test reports, and certification documents to support your bidding and approval processes.

During Application: Remote construction guidance, standardized installation manuals, and 24/7 technical support to ensure proper coating thickness and uniformity.

After Completion: Acceptance documentation assistance, fire inspection coordination, and batch traceability for quality management.

For complex projects, our senior engineers offer tailored construction solutions and fire resistance calculation verification.

FAQ

Q: How is product distinct from indoor products?

A: Weatherproofness matters. The UV blockers, moisture barriers, and anti-corrosion ingredients in our outdoor recipe survive rain, sun, and temperature extremes. Without these components, indoor coatings will fracture and peel within months of environmental stress.

Q: How long does the coating dry, and what precautions are needed?

A: Surface drying takes 4 hours and hard drying takes 24 hours at 25℃ and 50% humidity. Avoid rain, sunshine, and physical impact when curing. Avoid open flames and ventilate. Avoid dusting moist surfaces.

Q: Is it possible to decorate the fireproof layer?

A: Yes. Latex or fluorocarbon finishes can be applied once the fireproof coating hardens. Always do a small-area compatibility test to prevent chemical interactions that could damage fire performance.

Q: How thick must coatings be for different fire ratings?​​​​​​​

A: Fire resistance and substrate type determine thickness. Extremely thin applications (0.3-0.8mm) provide 0.5-1 hour protection. Steel constructions need adequate thickness calculation based on section factor and exposure conditions for ≥1.5 hour resistance. Our engineers can make project-specific suggestions.

Q: How can I prolong the coating's 8-year lifespan?

A: An annual visual inspection for cracks, peeling, or chalking. Softly scrub surfaces to eliminate dirt. Localised repairs for minimal damage are immediate. Avoid chemicals and mechanical damage. In hostile coastal or industrial locations, biennial examinations can detect damage early.
