Fire safety remains a cornerstone of modern construction, as fires pose significant risks to lives, property, and economic stability. Structural steel, a common building material, can lose its strength when exposed to high temperatures, leading to catastrophic collapses. Jotun, a global leader in protective coatings since its founding in Norway in 1926, has developed the SteelMaster range of fire-protective paints to address this challenge. These innovative intumescent coatings enhance fire safety and align with sustainable building practices, making them a vital tool for architects, builders, and specifiers.
The Critical Need for Fire Safety in Construction
Fires in construction sites or completed buildings can escalate rapidly, particularly when structural steel is involved. Steel begins to lose its structural integrity at temperatures as low as 400°C, which can lead to building collapse, endangering occupants, and causing extensive damage. High-profile incidents, such as the 2017 Grenfell Tower fire in London, have underscored the importance of robust fire protection measures. Global building regulations require structures to maintain stability for a specified period during a fire, allowing for safe evacuation and firefighting efforts. Passive fire protection systems, like intumescent coatings, are essential for meeting these standards and ensuring safety.
| Fire Risk Factors in Construction | Impact |
| Combustible materials | Accelerate fire spread |
| Unprotected steel structures | Risk of collapse due to heat |
| Inadequate egress routes | Hinders safe evacuation |
Jotun’s SteelMaster: A Revolutionary Solution
Jotun’s SteelMaster range of intumescent coatings is designed to protect structural steel from the effects of cellulosic fires, which are common in buildings involving materials like wood or paper. These coatings work by undergoing a chemical reaction when exposed to heat, expanding to form a thick, insulating char layer. This layer acts as a heat shield, slowing the temperature rise of the steel and maintaining its structural integrity. The SteelMaster range includes products like:
- SteelMaster 600WF: Provides up to 60 minutes of fire protection.
- SteelMaster 900WF: Offers up to 90 minutes of protection.
- SteelMaster 1200WF: Delivers up to 120 minutes of fire resistance.
These products are waterborne, low in volatile organic compounds (VOCs), and compliant with international fire safety standards, such as BS476 Part 20/21 and ASTM E84 Class A. They are suitable for internal environments up to corrosivity category C3 (ISO 12944-2) and can be applied to properly prepared carbon steel or galvanized steel with appropriate primers.
The Life-Saving Power of SteelMaster
The primary life-saving benefit of Jotun’s SteelMaster coatings is their ability to delay structural failure during a fire. By providing fire protection for 30 to 120 minutes, these coatings give occupants critical time to evacuate safely and allow firefighters to control the blaze. This is particularly vital in large or complex structures, such as airports, shopping malls, high-rise buildings, and industrial facilities, where evacuation can be time-consuming.
For example, SteelMaster 1200WF can protect steel structures for up to two hours, significantly reducing the risk of collapse. This extended protection saves lives and minimises property damage, facilitating faster recovery after a fire. The coatings’ ability to maintain structural integrity ensures that buildings remain stable, providing a safer environment for emergency response teams.
Sustainability in Fire Protection
In addition to their safety benefits, Jotun’s SteelMaster coatings are environmentally friendly. As waterborne coatings, they have low VOC emissions, reducing their environmental impact. According to Jotun, using SteelMaster can reduce CO₂ emissions by approximately 1.4 tonnes per tonne of steel protected, contributing to more sustainable construction practices. The coatings are part of Jotun’s Green Building Solutions, which align with certifications like LEED and BREEAM, recognized standards for sustainable building design. By minimizing the need for repairs or rebuilding after a fire, SteelMaster also conserves resources and reduces long-term environmental costs.

| Low VOC Emissions | Reduces air pollution |
| CO₂ Reduction | 1.4 tonnes per tonne of steel |
| Green Building Compliance | Supports LEED and BREEAM standards |
Real-World Applications
Jotun’s SteelMaster coatings are widely used in various construction projects, including airports, shopping centers, sports stadiums, and high-rise buildings. Their high-quality aesthetic finish makes them a favorite among architects, as they allow exposed steel to remain a design feature without compromising safety. Unlike traditional fire protection methods, such as cementitious coverings, SteelMaster provides a sleek, decorative finish that enhances the visual appeal of structures.
While specific case studies of SteelMaster applications are limited, the coatings’ effectiveness is well-documented through rigorous testing and certifications. For instance, SteelMaster 900WF is quality-guaranteed by Exova Warrington Fire Research and meets standards like Certifire CF 6140 and EN 13381-9. These certifications ensure that the coatings perform reliably in real-world fire scenarios, providing peace of mind for builders and property owners.
Expert Insights
Industry experts highlight the dual benefits of safety and sustainability offered by SteelMaster. John Warner, Global Category Manager for Cellulosic Fire Protection at Jotun Paints Europe, emphasizes, “Fire protection is not just about saving lives; it’s also about preserving the environment and reducing long-term costs.” Similarly, Jannicke Gulbrandsen, Global New Construction Solution Manager at Jotun Norway, notes that SteelMaster’s ease of application and compatibility with green building standards make it a preferred choice for modern construction projects. Graham Robinson, managing director at RC Fire Protection, with 25 years of experience in industrial paints, praises SteelMaster for its quick application and third-party certifications, which ensure compliance with fire safety regulations.
Economic and Practical Advantages
SteelMaster coatings are designed for efficiency, requiring fewer coats to achieve the desired fire protection compared to other intumescent products. This reduces labor and material costs, making them a cost-effective solution for construction projects. The coatings can be applied using airless spray or brushes, allowing for quick project completion. Additionally, SteelMaster’s compatibility with a range of Jotun primers and topcoats ensures flexibility for various project requirements. With proper maintenance, these coatings can last the lifetime of a building, offering long-term value.
Jotun’s SteelMaster fire-protective paints are a game-changer in construction fire safety, combining life-saving protection with environmental responsibility. By delaying structural failure during fires, these coatings provide critical time for evacuation and firefighting, protecting both lives and property. Their low environmental impact and compliance with green building standards make them an ideal choice for sustainable construction. As the construction industry continues to evolve, Jotun’s innovative solutions like SteelMaster will play a pivotal role in building safer, more resilient, and environmentally conscious structures.
