Modern Aluminum Cable Railings – Residential Exterior – Potomac, MD
February 2026
Capitol Iron Works completed the fabrication and installation of custom Aluminum cable railings for a Residential project in Potomac, MD. This installation covers approximately 20 feet of railing, securing the walkway from the back door to the basement stairwell wall. Design Style: Modern design featuring clean, horizontal cable lines. Structural Components: The framework features 4" x 4" Aluminum Square Tube main posts and a 3" x 2" Aluminum Rectangular Tube cap rail. Infill Detail: The infill consists of 3/16" 1 x 19 Type 316 Stainless Steel Cable for a Sleek and minimalist appearance. Finish: Finished in a premium White Powder Coat to ensure long-lasting durability and a clean aesthetic. The Problem We Solved: The client required a high-durability, rust-proof railing solution to secure a basement stairwell. By using aluminum and stainless steel cable, we provided a modern safety barrier that offers maximum visibility and requires zero maintenance, perfectly matching the high-end exterior of the Potomac residence. Capitol Iron Works is the go-to shop for modern, minimalist metal designs in Maryland. This Potomac project showcases our ability to take industrial-strength materials and turn them into elegant, transparent boundaries for the modern home.
