UK’s Leading Intumescent Steel Coating Specialists.

Intumescent paint is a thin-film, reactive coating applied to structural steel. When exposed to heat from a fire, it swells to form a thick, stable insulating char. This char protects the steel from critical temperatures that would cause it to lose strength and collapse, providing vital time for evacuation and firefighter intervention.

Yes. The Regulatory Reform (Fire Safety) Order 2005 and UK Building Regulations (Approved Document B) mandate that all commercial, industrial, and multi-residential buildings must have adequate passive fire protection. This includes protecting structural steelwork to maintain its integrity for a specified period during a fire.

Certified intumescent coatings can provide fire resistance for 30, 60, 90, or 120 minutes. The required rating depends on the building's size, use, and design, as specified by a structural engineer or fire consultant in accordance with Building Regulations.

When applied correctly to a properly prepared surface, intumescent coating is a permanent fire protection solution designed to last the lifetime of the building. It does not require scheduled maintenance but must be inspected if damaged (e.g., by impact or building works) to ensure its integrity remains intact.

Yes, but only with specific products designed for external use. External intumescent coatings are formulated to withstand UK weather conditions, including UV radiation, rain, and moisture. We use only certified external-grade systems to guarantee lasting performance.

Intumescent paint provides a thin-film, aesthetic finish that can be over-painted to match any décor, making it ideal for exposed architectural steel. Fireproof boards and sprays are thicker, bulkier solutions typically used where appearance is less critical. Paint offers design flexibility; boards are often a more utilitarian solution.

The cost varies significantly based on the required fire rating, the size and complexity of the steelwork (e.g., beam size, number of connections), and project location. It is typically priced per square metre. Contact us for a free, no-obligation survey and precise quote.

Absolutely. Upon completion, we provide a full certification package that details the product used, the fire rating achieved, and the application standard. This documentation is essential for your building’s fire safety file and for insurers, regulators, and building control sign-off.

Project timelines depend on the scale and complexity of the steelwork. Our efficient spray application methods and experienced teams allow us to complete work swiftly, minimising disruption to your project's critical path. We provide a detailed programme before work begins.
