Steel Structure Fire Resistant Coating

Thin / Thick Type Fire Protection Paint for Steel Beam & Steel Column

Caberry Steel Structure Fire Resistant Coating is available in thin and thick types. When exposed to high temperature, it forms an insulating charring layer to delay the temperature rise of steel substrates, prolong fire resistance time and gain more evacuation time. It provides reliable passive fire protection for various steel structures.

Good adhesion, anti-sagging, weather resistance and convenient application by spray, brush or roller. Widely adopted in commercial, industrial and public infrastructure projects.

• Commercial Buildings: Fire protection for steel beams and columns in office towers, shopping malls and exhibition centers.
• Industrial Plants: Steel structures in high-temperature zones of petrochemical factories and power plants.
• Public Facilities: Steel trusses and evacuation passages in stadiums, airports and metro stations.

Reliable Fire Endurance

Intumescent or dense thermal barrier layer slows heat conduction, keeps steel strength for specified fire rating hours.

Strong Adhesion & Anti-Sagging

Excellent bonding on primed steel surface, suitable for overhead and vertical steel members, not easy to sag.

Two Grades Available

Thin type: smooth finish for visible steel; Thick type: higher insulation for heavy industrial fire demand.

Multiple Application Ways

Airless spray for large-area construction; brush or roller for complex joints and touch-up repair.

Weather & Corrosion Resistance

Matches anti-rust primer system, provides dual protection against fire and atmospheric corrosion.

Stable & Easy Construction

Good storage stability, easy mixing, adjustable wet film thickness according to required fire rating.

Note: Dry film thickness and fire resistance hours are subject to local fire codes and project design.

1. Substrate Preparation

   Blast or grind steel surface to Sa2.5 grade: no rust, oil or dust. Apply anti-rust primer to boost adhesion and anti-corrosion performance.

2. Coating Preparation

   Mechanically stir fully per manufacturer ratio until lump-free. Let it mature for 10–15 minutes for stable performance.

3. Coating Application

   Spray: preferred for large area, high efficiency with airless sprayer. Brush / roller: for complicated joints, edges and repair touch-up.

• Surface preparation is critical; poor blasting will cause peeling and adhesion failure.
• Anti-rust primer is mandatory; do not apply directly on bare steel without approved primer system.
• Control single-coat wet thickness to avoid sagging on vertical and overhead steel members.
• Respect curing interval between coats; next coat only after previous layer fully cured.
• Stop construction under rain, heavy dew, high humidity or extreme low temperature.
• Fire rating must be verified with local fire authority and third-party test certificate.

• Package: Plastic bucket; private label / OEM labeling supported.
• Storage: Keep sealed, cool and shaded, avoid freezing and direct sunlight.
• Trade Terms: EXW, FOB Guangzhou, CIF, DDP available.

Sample policy: Sample cost and freight will be borne by the buyer.

Q: What is the difference between thin type and thick type?
A: Thin type is usually intumescent with smooth finish for exposed steel; thick type provides thicker thermal barrier for longer fire resistance.

Q: Must I use anti-rust primer?
A: Yes, primer is required for anti-corrosion and reliable adhesion system.

Q: Can I apply it by hand brush only?
A: Yes for small areas and repair, while airless spray is recommended for large steel structures.

Q: Can you issue fire test certificates for overseas project approval?
A: We can provide our standard test reports; we can also discuss third-party certification matching your local code.

Q: Can you provide English TDS and MSDS?
A: Yes, full English technical documents ready for customs clearance.
