Open Sightlines with Steel and Cable
Metal & Cable Railing Systems in Newtown for interiors and decks where you want unobstructed views and a streamlined profile
Kershbaumer Stairs & Rails fabricates and installs metal and cable railing systems throughout Newtown, Pennsylvania for homeowners who want railings that do not block light or sightlines. You need this type of system when traditional wood balusters feel heavy or outdated, when you want to open up a space visually, or when building codes require railing but you want to minimize its visual mass. Cable systems use horizontal stainless steel strands tensioned between posts, while metal rails can include powder-coated steel, wrought iron, or brushed aluminum depending on the setting.
The crew installs vertical posts anchored to the stair structure or deck framing, then threads cables through drilled holes and tensions them using adjustable fittings until each strand is taut and meets spacing requirements. Metal handrails run along the top, providing grip while the cables below act as the infill. Powder coating protects steel from rust, and stainless components resist corrosion in outdoor installations where moisture and temperature swings are common.
If you want a railing that meets code without compromising your view or adding visual clutter, a cable or metal system delivers the required safety barrier with minimal interruption to the space.
What Metal and Cable Systems Provide
You will see posts set at intervals that allow cable spans to remain rigid without sagging, typically no more than four feet apart.
Each cable is tensioned using a turnbuckle or swaged fitting, and the spacing between cables is kept below four inches to prevent small children from slipping through. Metal handrails are welded or bolted to posts, and corners receive custom fittings that maintain clean lines without bulky connectors.
Once installed, the railing will feel firm when gripped, with no flex or movement in the cables. Sightlines remain open, and the thin profile of the cables makes the space feel larger and brighter. Kershbaumer Stairs & Rails custom-builds each system to fit the exact dimensions and angles of your staircase or deck, accounting for post placement, cable count, and finish selection.
Cable systems require periodic tensioning as the strands settle and temperature changes cause slight expansion or contraction. Outdoor installations should be inspected annually and cables re-tensioned if slack develops. Metal railings do not replace structural posts or supports, so the underlying framing must be sound and properly anchored before railing installation begins.
What to Know Before Installing Cable Railings
Cable and metal systems work differently than wood railings, and these questions address installation details, maintenance, and code considerations.
What is the maximum spacing allowed between cable strands?
Building codes typically require cable spacing of four inches or less measured vertically, and the crew calculates the number of cables needed based on the total height of the railing run.
How often do cables need to be re-tensioned?
Initial tensioning is done at installation, and you should check tension after the first few months, then annually, especially on outdoor decks in Newtown where seasonal temperature shifts can cause slight loosening.
Why choose stainless steel over coated cable?
Stainless steel resists rust and corrosion without coatings that can chip or wear, making it the preferred choice for exterior railings and high-humidity areas where durability matters more than cost.
When is cable railing not a good fit?
Cable systems require clear spans and sturdy posts, so they work best on straight runs and gentle angles, and they may not be ideal for very steep or curved staircases where tension and alignment become difficult to maintain.
How do I clean cable railings?
You wipe down stainless cables with a damp cloth and mild cleaner to remove dust and fingerprints, and you inspect fittings for tightness while cleaning to catch any loosening before it affects the system's rigidity.
Kershbaumer Stairs & Rails builds metal and cable railing systems that meet local building codes while keeping views open and designs clean. If you want safety without visual weight, these systems provide the required protection with a modern profile that suits both interior stairs and outdoor decks in Newtown.
