For projects that require a balance of cost-efficiency and certified load-bearing strength, our C16 Structural Timber Purlins are the professional choice. Whether you are framing a stable roof, installing industrial joists, or supporting external cladding, this timber is processed in our ISO9001-certified plant to ensure every length meets rigorous British standards.
Each piece is CE Marked and high-pressure treated to Use Class 3, making it highly resistant to the UKís unpredictable weather, fungal rot, and insect attacks.
Why Choose Our C16 Treated Timber?
Certified Structural Strength: C16 grading ensures the timber is kiln-dried and strength-tested for reliable load-bearing performance.
Advanced Weather Protection: Treated to Use Class 3 (UC3), our purlins are specifically designed for outdoor use where the timber is not in contact with the ground but is exposed to the elements.
Versatile Application: Ideal for roofing rafters, floor joists, stud walling, and general structural framing in agricultural, commercial, and domestic builds.
Industrial Scale lengths: We stock lengths up to 20ft (6.1m), allowing for fewer joints and stronger continuous spans.
