A high quality fireproof coating, also known as a fire protective or intumescent covering, is one of the most practical and effective ways to ensure structural integrity during a fire incident. Modern buildings, industrial facilities, and high risk environments require adequate passive fire protection to comply with safety regulations and to protect both human life and property. Integrating a reliable fireproof system can prevent heat transfer to the structure, extend evacuation time, and limit structural collapse under high temperature.
At TETIS SAZEH, fire protection is more than an engineering requirement; it is a commitment to reliability and durability. Our fireproof coating solutions are designed and executed in full compliance with international standards, providing long term resistance and safety for diverse types of structures.
What is Fireproof Coating
A fireproof coating is a specially formulated protective layer applied over structural steel, concrete, or other surfaces to maintain load bearing capacity under fire conditions. These coatings react when exposed to heat, forming an insulating barrier that restricts heat transmission. The result is increased fire endurance time and the preservation of the structural form for a critical period that allows occupants to evacuate safely and firefighting operations to take effect.
Fireproof coatings are used in commercial towers, refineries, industrial plants, warehouses, and large infrastructure projects where high thermal resistance is a fundamental design requirement.
Importance of Fireproof Protection in Modern Structures
When a fire breaks out, the ambient temperature can exceed 600°C in just a few minutes. At that point, steel loses a significant portion of its strength, and concrete can experience cracking or spalling. A properly applied fireproof coating mitigates these risks by delaying structural failure and stabilizing the entire framework.
Beyond safety, the use of certified coatings also helps meet building codes and insurance requirements, ensuring the project obtains all official fire safety approvals without delay.
Types of Fireproof Coating
Fireproof coverings vary depending on their chemical composition and application method. The three main categories include:
Intumescent Coating: These paints expand multiple times their original thickness when exposed to heat, creating a foamed char layer that restricts heat transmission. They are ideal for exposed steel elements in architectural and commercial projects where aesthetics and minimal thickness are important.
Cementitious Coating: Cement based coatings are composed of lightweight aggregates, binders, and additives that provide thick and durable fireproofing. They are typically used in industrial and oil and gas facilities where long duration fire resistance is essential.
Gypsum Based Coatings: Gypsum coatings are lightweight, cost effective materials commonly applied in interior building spaces to increase the fire rating of walls, ceilings, and columns.
Each of these coating types provides a different level of protection and is selected according to the projects environmental conditions, required fire rating, and structural type.
Fire Protection for Steel Structures
Steel is widely used due to its strength and ease of fabrication; however, it is highly sensitive to high temperature. Without adequate protection, steel structural members can lose up to 50% of their strength within minutes of a fire event. Applying a certified fireproof coating helps maintain the integrity of beams and columns, ensuring that the building remains stable long enough for evacuation and firefighting activities.
The proper thickness of the coating is determined during the design stage based on fire duration ratings such as 60, 90, or 120 minutes. TETIS SAZEH engineers ensure precise calculation and application of these coatings to deliver performance that meets or exceeds regulatory requirements.
International Standards and Approvals
All fireproof coatings used by TETIS SAZEH comply with internationally recognized standards, including NFPA (National Fire Protection Association), UL (Underwriters Laboratories), and BS (British Standards). In addition, our local expertise ensures that each project meets Irans national building codes and fire departments regulations.
Adherence to these standards is crucial not only for safety but also for gaining approval from official fire authorities and preventing costly project delays.
Application Process of Fireproof Coatings
The efficiency of a fireproof coating depends not only on material quality but also on proper surface preparation and professional installation. The general process includes:
- Surface Preparation: Cleaning and removing contaminants, rust, and oils to ensure proper adhesion.
- Primer Application: Applying an approved primer to provide bonding and protect against corrosion.
- Coating Application: Spraying or troweling the fireproof material to achieve the specified thickness.
- Inspection and Quality Control: Conducting adhesion, thickness, and curing tests to verify compliance with standards.
At each stage, TETIS SAZEH utilizes qualified personnel and advanced monitoring to ensure durability and safety performance as expected in real fire conditions.
Advantages of Fireproof Coating
The key benefits of using a professional fireproof coating system include: enhanced occupant safety, prevention of structural collapse, compliance with building regulations, increased property value, and long term durability. For industrial applications, it also ensures operational continuity by minimizing damage and downtime after a fire incident.
Why Choose TETIS SAZEH for Fireproof Coating Services
TETIS SAZEH provides comprehensive fire protection solutions combining design, material supply, and installation. Our expertise covers both passive and active fire protection systems, allowing clients to have a single reliable partner for all their fire safety needs. We deliver projects with international grade materials, skilled workmanship, and complete documentation for local authority approval.

Integration with Other Fire Protection Systems
Fireproof coating serves as the foundation of passive protection, working seamlessly with active systems such as sprinkler systems, fire booster pumps, and firefighting valves. This integrated approach ensures that even if active systems face a temporary failure, passive coatings will continue to protect structural integrity until firefighting operations suppress the fire.
Just as the Fire Booster Pump provides consistent water pressure during emergencies, and the Fire Sprinkler System automatically activates to extinguish flames, the fireproof coating maintains the structures stability. Together, these systems create a comprehensive safety network designed and supervised by our certified Firefighting Consultant team.
