Post Materials and Finishes

Metal posts are an essential element of cable, rod, and glass railing systems. StairSupplies manufactures metal post from three materials: 304 Stainless Steel, 316 Stainless Steel, and Aluminum. Each material has a distinct look, so you’re sure to find one that suits your style.

Brushed Stainless Steel

Popular in both interior and exterior designs, Brushed Stainless Steel is a premium finish for cable railing posts. From a distance, Brushed Stainless Steel shines with its bright, reflective surface. Up close, you can see that the brushed pattern has a smooth, consistent flow running vertically up the post. The even brushing makes  Brushed Stainless Steel the optimal choice for customers seeking lustrous posts with a modern finish.

Brushed Aluminum with Clear Coat

While Brushed Stainless Steel is our most popular metal post finish, some customers prefer the look of Brushed Aluminum. Unlike Brushed Stainless Steel, which flows in vertically, the Brushed Aluminum finish has lines moving in all directions. This gives it a more raw and random look that works well with projects that capitalize on its distinct appearance.

Powder Coated Posts

While stainless steel and aluminum are vastly different when brushed, they are nearly indistinguishable when powder coated. Powder coating your posts leaves them with a smooth finish in the color of your choosing. While some projects may require the additional strength of 304 or 316 stainless steel, powder coated aluminum posts are a suitable, cost effective option for most applications.
