Portland Stone Ware focuses on supplying solid, quality products for the lumber and masonry industries. We specialize in assembling concrete-filled columns that have supported buildings all over the northeast and mid-Atlantic states. Since 1970, PSW had been known for the simply designed, red Portland Column. In 2019, PSW acquired Dean Column Co. and began to manufacture products with a patented locking system, known as the Structural Lock System. This system is an embedded fastening unit installed in Lally Lock Columns, adjustable columns, posts, or bracing to improve connectivity of support and attachment to beams. This allows installers to simply screw in a wide variety of cap plates that fit almost any beam configuration and eliminates the costly and timely need for welding.
We also proudly distribute Delta® products, which are premium moisture management building materials that protect property, save energy, and create comfort for both residential and commercial buildings.
