YellaWood Porch Columns Featured in Modern Colonial House


No compromises. In strength or beauty.

Building with YellaWood® brand pressure treated glulam porch columns is one of the easiest decisions you’ll face during construction. Made from high-grade lumber for structural durability and beautiful appearance, the strength ratings of YellaWood® columns rival more expensive PVC and composite options at a budget-friendly price. Plus, there’s no more veneer wrapping for a clear finish. Columns are bonded with a formaldehyde-free exterior laminate that’s environmentally preferable, building-code compliant and uncompromisingly strong.

* Please note: Because YellaWood® columns are kiln dried after treatment, they must be primed and painted or stained immediately after installation.
