Home / Products / Glue Laminated Timber / Round Glulam Column

Round glulam columns are structural timber elements made by laminating multiple layers of wood—typically softwoods like spruce, pine, or Douglas fir—into a cylindrical shape using high-strength adhesives. The term “glulam” stands for glued laminated timber, and the “round” refers to the column’s rotationally symmetrical profile, as opposed to traditional square or rectangular posts.

What Are Round Glulam Columns?
They are Glued Laminated Timber (Glulam) elements that are manufactured to be perfectly cylindrical. The process involves bonding multiple layers of dimensional lumber together with durable adhesives. This lamination process enhances the wood's strength and stability, while the circular shape is achieved either by shaping the beam after lamination or by a specialized process of arranging the laminations to form a round cross-section.

Why Use Round Glulam Columns?
Architectural Flexibility: The smooth, round form of these columns offers a sophisticated alternative to square posts, allowing for a softer, more fluid design aesthetic. They are often used in high-visibility areas like lobbies, entryways, and atriums where their form can be fully appreciated.
Uniform Strength: The lamination process ensures that the column has a consistent strength profile in all directions, making it a reliable structural element for supporting heavy loads.
Sustainability: Sourced from renewable timber, these columns are a sustainable choice for building projects. The efficient lamination process also minimizes waste.
Customization: Round glulam columns can be produced in a wide range of diameters, lengths, and finishes, allowing for tailored solutions that meet specific design and structural requirements.

Round glulam columns are a favorite in mass timber construction and architectural design where both strength and style are essential. They’re often used in open-frame structures, atriums, and public buildings to create warm, organic spaces with engineered precision.
