- Product Description
Fireproof Coating for Metal: Protection for Steel Structures
Henan Banggu's fireproof coating for metal works at a company level and is backed by more than 30 years of experience making coatings. Our special steel structure coatings can fight fire for up to two hours, can handle temperatures up to 1200℃, have grade 0 adhesion, and are very good at keeping things from rusting. Our coatings dry quickly and are easy to use by spraying or brushing them on. They keep their Class A non-combustible performance (GB 8624-2012) and VOC content below 100g/L. Contractors all over the world trust us to protect high-rises, factories, bridges, and other industrial sites with our tried-and-true formulas and full technical support.
Why Choose Our Fireproof Coating for Metal Structures?
Proven Fire Resistance Performance
When there is a fire, your steel buildings are in grave danger. When temperatures go above 500℃, steel that isn't protected loses its power quickly and could break in 30 minutes. When exposed to fire, our product forms a thick layer of carbonised heat insulation that greatly slows the rate at which steel beams, columns, and trusses heat up.
With fire resistance rates of at least two hours and temperature resistance up to 1200℃, you can be sure that you are safe. This buys important time for getting people out of the building and starting fire rescue efforts.
Fast Application, Minimal Downtime
On your projects, time is important. Our coats dry quickly on the surface (in about 4 hours) and completely hard in 24 hours. The thin width of the coating cuts down on material use while still providing competitive performance.
You'll like how the formula is very light and doesn't add much to the structure's load—essential for engineering tasks where weight savings are important.
Environmental Compliance You Can Trust
Our products are certified by ISO 9001, ISO 14001, and ISO 45001 to make sure they meet strict worldwide standards. Our coatings are safe for use indoors and outdoors around the world because their VOC content goes well below the limits set by government agencies.
You can be sure that our fireproof coating for metal will meet environmental standards in the Middle East, Southeast Asia, and other places.

Optimal Application Scenarios
Indoor Steel Structures
Perfect for steel beams and columns in commercial buildings, warehouses, and manufacturing facilities. For indoor use, our coating provides excellent protection without additional topcoats.

Outdoor Steel Projects
When your project requires outdoor durability beyond 5 years, we recommend applying a UV-resistant and weather-resistant topcoat over our base fireproof coating. This combination ensures long-term performance against environmental exposure.
Specialized Industrial Applications
Our coatings protect steel trusses in bridges, industrial frameworks, and high-temperature environments. The anti-corrosion properties add extra value in challenging conditions.

FAQ
Q1: What's fireproof coating's purpose?
A: A fireproof coating is useful and fire retardant. It protects steel structures from fire by insulating and isolating oxygen. This reduces substrate ignition and deterioration, allowing for evacuation and decreasing fire spread and property damage.
Q2: What fire rating variances affect my project?
A: Fire ratings show steel coating durability. GB 14907-2018 classifies coatings as NCB (ultra-thin), NB (thin), and NH (thick) with 0.5–3-hour fire resistance. Internationally, EN 13501-1 utilises A1–F. Choose higher grades for longer protection based on building type and local restrictions.
Q3: Is construction complicated? Do I need pros?
A: The basic procedure includes substrate treatment, primer application, numerous layers of coating, and curing. Proper coating thickness and homogeneity are important but not difficult. Small jobs can be managed by competent builders. Professional teams maintain fire rating compliance for large or high-risk projects.

Q4: What is the validity term and when should I reapply?
A: Weathering reduces exterior coatings to 3-5 years, whereas indoor treatments last 5-8 years. Check for cracks, peeling, and chalking beyond expiration. Remove and reapply old coating if it deteriorates. Extended service life may require just minimal repairs on intact coatings.
Q5: Does your coating work with other ornamental finishes?
A: Decorative coatings can be applied over our fireproof coating. Apply and dry our product first. Finish with latex or fluorocarbon paint. Maintain coating compatibility to avoid chemical reactions. Prior to full-scale use, small-area testing should establish no harmful effects.
