This project involved the specification, testing and application of protective coating systems for structural steel and metal elements within a commercial building.
Project Description
This project involved the specification, testing and application of protective coating systems for structural steel and metal elements within a commercial building. The works included fire protection using intumescent coatings, corrosion protection for exposed steelwork, and specialist coatings for metal roof cladding.
The objective was to ensure long-term durability, compliance with fire safety standards and resistance to environmental exposure.
Project Requirements
- Fire resistance ratings of 30, 60 and 90 minutes for structural steel
- Corrosion protection aligned with environmental classification
- Durable systems with minimal maintenance requirements
- High-quality aesthetic finish for exposed steelwork
- Full compatibility across all coating layers
Testing & Assessment
A comprehensive inspection and testing regime was carried out prior to installation to ensure correct product selection and system performance.
- Environmental conditions assessed in line with exposure classifications
- Steel substrates inspected for contaminants and existing coatings
- Abrasive blasting trials completed to achieve required preparation standards
- Surface profile and cleanliness testing undertaken
- Adhesion and compatibility testing carried out on sample areas
Coating Systems
Intumescent Fire Protection
- Anti-corrosive primer system
- Intumescent coating providing fire resistance
- Protective topcoat where required
- Fire ratings achieved up to 90 minutes
Corrosion Protection
- Multi-coat system tailored to environmental conditions
- Enhanced edge protection applied
- Designed for long-term durability
Roof Cladding & Metal Elements
- Coatings applied to roof sheets and flashings
- Resistance to UV exposure and water ingress
- Flexible systems to accommodate movement and weathering
Application Process
- Abrasive surface preparation and cleaning
- Controlled application using spray, roller or brush
- Monitoring of environmental conditions throughout
- Wet and dry film thickness testing
- Inspection and quality control at each stage
Outcome
- Fire protection requirements successfully achieved
- Corrosion protection aligned with exposure conditions
- Improved durability and service life of steel elements
- Compliance with relevant standards and specifications
Conclusion
The project demonstrated the importance of a carefully specified and tested coating strategy. By combining detailed assessment with high-performance systems, long-term protection, durability and compliance were successfully achieved across all steel elements.
