Product Description

Fireproof Coating for Steel Structures Long Fire Resistance Time

When you need to protect big industrial and commercial steel frames, you need more than just basic security. With fire resistance rates of up to 6 hours, our Fireproof Coating for Steel Structures long fire resistance time works really well. Engineered by Henan Banggu Fire Technology Co., Ltd., this intumescent covering quickly grows when it comes into contact with flames, making a thick layer of carbonised protection that keeps steel from breaking. With a thermal conductivity of as little as 0.12 W/(m·K) and a temperature resistance of up to 1050°F, this coating provides enterprise-level fire protection backed by more than 30 years of experience making coatings and full ISO 9001, ISO 14001, and ISO 45001 certifications.

Why Extended Fire Resistance Time Matters for Your Project?

It only takes 550°F for steel to lose half of its power. If you don't have the right safety measures in place, your building could fall down in minutes during a fire.

You can use our sealing method to buy important time. It makes the passage of heat much slower. Your steel supports, beams, and frames will be able to hold more weight for longer. It will be safer to evacuate. Better safety for assets. And full agreement with all international rules for fire safety.

This is more than just painting. You are putting up a barrier that will save lives and only go off when it needs to.

Key Benefits That Set Us Apart

Fire Protection Performance

Our product complies fully with GB 14907-2018 national standards. When flames strike, the coating expands rapidly—forming a protective char layer that insulates steel from extreme heat. You get fire resistance ratings from 0.5 to 6 hours depending on application thickness.

Fast Application, Faster Project Completion

Time is money on construction sites. Our quick-drying formula means surface drying in just 0.5–1 hour. Full cure happens within 12–24 hours. You can apply multiple coats efficiently. Short construction periods keep your project on schedule and under budget.

Lightweight Yet Powerful

Heavy coatings add unnecessary structural load. Our thin-coat technology minimizes weight while maximizing protection. At just 3–50mm thickness, you get robust fire resistance without compromising your building's design integrity.

Fireproof Coating for Steel Structures long fire resistance time

Excellent Adhesion and Durability

With bonding strength exceeding 0.15 MPa, the coating sticks firmly to steel substrates. It resists cracking, peeling, and powdering when applied correctly. Water resistance testing shows no blistering even after 72 hours of exposure.

Environmentally Responsible Formulation

You don't have to choose between safety and sustainability. Our coating meets ISO 14001 Environmental Management System standards. Low VOC content—water-based variants under 120g/L—means safer working conditions and compliance with global environmental regulations.

Flexible Customization Options

Every project has requirements. We offer both OEM and ODM services. Standard colors include white and light gray, with custom color matching available. Our Fireproof Coating for Steel Structures long fire resistance time adapts to your specific fire rating needs, aesthetic preferences, and budget constraints.

Complete Technical Support Throughout Your Project

Proven Applications Across Industries

This coating system protects steel structures in:

Industrial Plants: Manufacturing facilities requiring extended evacuation times
Commercial Buildings: Shopping malls, office towers, hotels with complex steel frameworks
Warehouses: Large-span steel structures storing valuable inventory
Public Venues: Stadiums, gymnasiums, convention centers with high occupancy
Infrastructure: Steel beams, columns, trusses, and space frames in critical applications

FAQ

Q1: What is "intumescent" and how does it work?

A: Our intumescent coating foams and expands quickly in fire. It resists flames and heat with a strong carbonised insulation layer. This reduces steel component temperature increase and structural instability. Expanding 10-50 times the original thickness creates a thermal barrier that protects steel during fires.

Q2: How do solvent-based and water-based versions differ?

A: Solvent-based coatings dry faster, adhere better, resist water, and harden. Projects requiring strength and weather performance benefit from them. Water-based versions are greener and smell less, but they dry slower and have poorer water resistance. Project timetable, environmental criteria, and performance goals determine your option.

Q3: What coating thickness is needed for individual fire resistance ratings?

A: Reference values from test reports: 0.5-hour rating requires 1.5mm; 1.0-hour needs 1.5–2.2mm; 1.5–3.3mm; 2.0–4.5mm. For 3-6-hour ratings, thickness rises proportionately. Please consult our technical staff and official test documents for your steel section factors and project needs.

Q4: Is this coating suitable for outside steel structures?

A: Indoor use is intended for this product. Our outdoor intumescent or non-intumescent fire-retardant coating solutions are ideal for steel constructions exposed to UV and weather. Outdoor variations include weather-resistant topcoats to preserve fire protection.

Q5: Does the coating pass fire safety tests?

A: Yes, if applied properly with thickness and documentation. Our product meets GB 14907-2018 and has national fire prevention product test results. We supply all compliance certifications and factory inspection documents. Product documentation, visual surface quality, and dry film thickness measurements are checked on-site to guarantee design conformity.
