Spruce Round Glulam Column

Product Description

Spruce round glulam columns are structural timber elements crafted by laminating multiple layers of spruce boards into a cylindrical form. Combining the lightweight properties of spruce with the dimensional stability of glulam technology, these columns offer both load-bearing performance and aesthetic appeal for modern timber construction.

Key Characteristics

Key Features 
•Material: Strength-graded spruce, finger-jointed and laminated under pressure
•Shape: Precisely machined round profile for clean, uniform appearance
•Finish Options: Planed smooth, sanded, or treated for fire and weather resistance
•Grades: Visual-grade for exposed applications; industrial-grade for structural use

Common Applications

Benefits
•High Strength-to-Weight Ratio – Ideal for vertical load-bearing in open spaces
•Dimensional Stability – Resists warping, twisting, and shrinkage over time
•Architectural Versatility – Suitable for pavilions, atriums, public buildings, and modern homes
•Sustainable – Made from renewable spruce and often PEFC or FSC certified
•Elegant Appearance – Natural wood grain and round form add warmth and softness to structures

Additional Instruction

Spruce round glulam columns are a standout choice for designers and engineers seeking precision-crafted timber elements that deliver both structural integrity and visual impact. Whether used in mass timber buildings or decorative open-frame systems, they offer a refined solution for contemporary architecture.
