Cable railing for decks can be ordered with special tools & components to mount it on level surfaces, and stairs can be mounted at an angle. The installation process is simple and made easier with our rent-a-tool program. Either way, it’s simple for the DIY homeowner to install horizontal cable railing systems into a deck or staircase. With an industry-leading powder coating process, cables are the perfect steel cable fence for your indoor or outdoor project.

Cable railing is a versatile system that comes with dozens of customizable options. Order the posts in either aluminum or stainless steel, and make them your own with one of our powder coats. If your project is located on the coast, order custom-made exterior metal railing to hold up against salty sprays. Cable railing posts can be mounted into many different surfaces, such as wood, composites, concrete, and more.

When to Use Aluminum or Stainless Steel for Cable Railing

If you’re looking to install a new system, you are probably wondering what material you should use. StairSupplies offers two different metal options: aluminum and stainless steel for cable railing. Both materials are highly durable and look great after installation. Aluminum is less expensive and it is also lighter, making it a bit simpler to install. Stainless steel is more corrosion-resistant, so it’s well-suited for outdoor projects.

Our stainless steel posts are available in two types:

  • 304 SS
  • 2205 SS

304 is ideal for most guardrail systems. It’s durable with a beautiful brushed look. 2205 is best for coastal environments, because the stainless steel balcony wire is able to withstand years on any deck overlooking salt water.

All of the cable railing wiring and components are made from stainless steel.
