Fireproof Paint for Steel Structures

Fireproof Paint for Steel Structures

Fireproof Paint for Steel Structures from Henan Banggu Fire Technology ensures that your steel infrastructure is safe from fire risks and works at a business level. When our covering comes into contact with flames, it quickly spreads, creating a thick layer of carbonised insulation that stops the steel from heating up too much. Our solution meets the requirements of GB 14907-2018. It has a bonding strength of at least 0.15 MPa, a thermal conductivity of at least 0.12 W/(m·K), and a fire resistance grade of between 0.5 and 3 hours for thin-type applications and 2 to 6 hours for thick-type formulas. With more than 30 years of experience making coatings and a facility worth 20 million yuan, we can help you get solid fire safety for tall buildings, factories and big building projects.

Why Choose Our Fireproof Paint for Steel Structures?

Fire Protection Technology

You should protect your steel beams, frames, and trusses in the best way possible. When heat hits our intumescent covering technology, it quickly foams up. This growth makes a shield that protects steel parts and slows down the rise in temperature. During important fire events, you keep the structure from deforming and keep its load-bearing ability.

Environmentally Safe and Low Odor

You don't want to give up safety. It meets ISO 14001 environmental standards and doesn't have any dangerous volatile chemicals in it. You get green approval and peace of mind for indoor uses whether you're working on factories, shopping areas or apartment buildings.

Fast Drying, High Efficiency

Short deadlines don't mean you have to skimp on quality. It's dry to the touch in just half an hour to an hour and a half, and it's fully set in twelve to twenty-four hours. It can be put on by spraying, brushing, or rolling, but spraying is best for big jobs. This means the job will be finished faster and the cost of labour will go down.

Lightweight and Decorative

Typical fire safety measures take up more space. Our thin-coat design keeps the structural load to a minimum while still looking professional. You can choose from common colours like white and light grey, or you can make your own. The smooth finish makes your project look better without losing safety.

Complete Certification Portfolio

The paperwork for your projects needs to be able to pass review. We offer certifications in ISO 9001, ISO 14001, and ISO 45001, as well as national test results for fire safety products. Each batch comes with the right paperwork to make sure it passes fire safety tests and meets the needs of foreign projects.

Technical Parameters

Application Guidelines

Ideal Conditions

When applying Fireproof Paint for Steel Structures, you'll get best results when ambient temperature ranges between 5°C and 35°C, with relative humidity below 85%. Avoid application during rain, fog, or high wind conditions. The substrate temperature should stay at least 3°C above the dew point.

Coverage and Thickness

For accurate planning, expect theoretical coverage of approximately 1.2–1.5 kg/m² per millimeter of thickness. Your actual usage depends on the fire resistance rating you need:

• 0.5-hour protection: ~1.5 mm thickness
• 1.0-hour protection: ~1.5–2.2 mm thickness
• 1.5-hour protection: ~1.8–3.3 mm thickness
• 2.0-hour protection: ~3.0–4.5 mm thickness

Surface Preparation

Your substrate must be rust-free before application. Proper surface treatment ensures maximum bonding strength and long-term performance. After full curing, you can apply a compatible topcoat to enhance decorative appeal and stain resistance without affecting fire protection capabilities.

FAQ

Q1: How does intumescent technology work?

A: The coating immediately foams and expands to produce a dense carbonised insulating layer that prevents flames and heat when exposed to fire. This reduces steel temperature increase, ensuring your building doesn't quickly lose stability during a fire and meeting the fire resistance rating.

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

A: Solvent-based variants dry quicker, adhere better, resist water, and harden. They're perfect for difficult interior jobs. Water-based products are greener, smell less, dry slower, and have reduced water resistance.

Q3: What criteria does your product meet?

A: Our coating meets fire safety inspections and international project standards by meeting national standard GB 14907-2018 "Fireproof Coatings for Steel Structures" and national fire protection product test reports.

Q4: Can this coating be used outdoors?​​​​​​​

A: This product is indoors-only. Outdoor applications exposed to UV and weather for more than 5 years require intumescent or non-intumescent fire-retardant coatings with weather-resistant topcoats.

Q5: Does the coating pass fire testing?

A: Your project can pass fire safety inspections with test results, certificates of conformity, factory inspection records, and adequate application thickness. For compliance, we give all documents and acceptance support.
