For structural steel fire protection, we use the **Nullifire range of high-performance intumescent coatings**, engineered to provide certified passive fire protection while delivering a durable, professional finish. Designed for application to correctly prepared and primed structural steel, the system expands when exposed to extreme heat, creating an insulating char layer that helps protect the steel and maintain its structural integrity for the specified fire resistance period. Developed to meet the demanding requirements of modern commercial, industrial and public sector construction, Nullifire intumescent coatings are independently tested and certified to recognised British and European standards. When applied over an approved primer and, where required, finished with a compatible topcoat at the specified dry film thickness, the system provides long-term performance, excellent adhesion and reliable fire protection in a wide range of internal and external service environments. To ensure complete compliance, every project is carried out in accordance with the manufacturer's specification using calibrated application and inspection equipment. Environmental conditions, including relative humidity, air temperature, steel surface temperature and dew point, are monitored throughout application, while wet film thickness is checked during spraying and dry film thickness is verified upon completion using calibrated digital coating thickness gauges to confirm the required protection has been achieved. Ideal for structural steelwork within offices, warehouses, schools, hospitals, retail developments and industrial buildings, Nullifire intumescent coating systems provide an efficient alternative to traditional fire protection methods while maintaining the clean architectural appearance of exposed steel. Every project is supplied with comprehensive inspection records, environmental data, coating thickness reports and certification, providing a complete quality assurance package for client approval, building control and project sign-off.
