The Indoor Expansion Type Steel Structure Fireproof Coating (Water-Based) is a next-generation protective solution designed to enhance the fire resistance of structural steel.
Product Introduction
The Indoor Expansion Type Steel Structure Fireproof Coating (Water-Based) is a next-generation protective solution designed to enhance the fire resistance of structural steel. When exposed to high temperatures, the coating expands into a dense, uniform carbonized foam layer, effectively insulating the steel and prolonging its stability under fire conditions. This water-based, environmentally friendly formulation combines safety, performance, and ease of use, making it ideal for modern construction projects where both safety and sustainability are priorities.
Product Details
This coating is manufactured using premium raw materials and advanced dispersion technology. It comes in ready-to-use form, requiring only mixing before application. The coating is white or light-colored, allowing for direct top-coating with decorative finishes. Application methods include spraying, rolling, or brushing, and it adheres strongly to steel substrates, forming a seamless protective layer. Typical dry film thickness ranges between 1.5–3.0 mm depending on the fire-resistance rating requirements.
Product Advantages
High Fire Resistance: Provides up to 2–3 hours of fire protection for indoor steel structures.
Water-Based & Eco-Friendly: Low VOC, non-toxic, and safe for indoor application.
Strong Adhesion: Resists cracking, peeling, and delamination under long-term service.
Lightweight: Minimal added load on steel components compared to traditional cementitious coatings.
Aesthetic Finish: Smooth surface that can be painted over to match interior design requirements.
Easy Application & Maintenance: Simplifies construction schedules and reduces labor costs.
Product Features
Intumescent expansion ratio of 20–30 times its original thickness when exposed to fire.
Fast drying and strong compatibility with primers and finishing coats.
Excellent resistance to humidity and indoor atmospheric conditions.
Adjustable fire-resistance thickness to meet different building codes and project needs.
Product Applications
This coating is widely used in:
Industrial and commercial buildings (factories, warehouses, office towers).
Public facilities (stadiums, theaters, airports, exhibition halls).
Residential high-rise buildings and underground structures.
Indoor steel beams, columns, and trusses requiring certified fire protection.

Products are packed in sealed pails (20kg or 25kg) to guarantee freshness during transport. We offer fast delivery, customized packaging options, and support for international logistics.
FAQ
Q1: How long is the shelf life?
A1: The product can be stored for 12 months in a cool, dry environment in unopened containers.
Q2: Can it be applied directly to bare steel?
A2: A primer is recommended for better adhesion and corrosion resistance before applying the fireproof coating.
Q3: Is it suitable for outdoor use?
A3: This product is designed for indoor applications. For outdoor use, please consult us for specialized coatings.
Q4: How to determine the required coating thickness?
A4: Thickness depends on fire-resistance requirements (30, 60, 90, or 120 minutes). Technical support and calculation sheets are available upon request.
Q5: Is it safe for workers?
A5: Yes. Being water-based and low-VOC, it ensures a safer construction environment with reduced health risks.
