Stainless Steel Cable Handrail Assemblies

STAINLESS STEEL HANDRAIL & GUARDRAIL CABLE SYSTEMS

SYSTEM 2000 - STAINLESS STEEL HANDRAIL & GUARDRAIL CABLE SYSTEMS

For over a decade Seco South has been the leader in stainless steel cable handrail industry. These unique systems offer the designer a whole new approach to interior and exterior railing design capabilities. Our cable railing systems are used on commercial and residential projects all over the world. The incredible transparency as well as the extremely low maintenance is what set these systems apart from other obtrusive and high maintenance railing systems.

Our handrail systems satisfy existing code requirements for use nationwide for horizontal or vertical handrail designs.

Seco South offers a variety of different cable systems to choose from. Our stainless steel cable infill systems for railings utilize 1/8", 3/16" or 1/4" cable diameters. Larger sizes are available if desired. The type of cable we use is either a 1 x 19 or 7 x 7 construction.

We have broken our stainless steel handrails down into a simple part number system for specifying and ordering:

  • SYSTEM 2100 - Assemblies that use threaded studs at each end of the cable.
  • SYSTEM 2200 - Assemblies that use fork style connections at each end of the cable.
  • SYSTEM 2300 - Assemblies that use eye style connections at each end of the cable.
  • SYSTEM 2400 - Assemblies that use a dome head style connection at each end of the cable.
  • SYSTEM 2500 - Assemblies that use a stemball style connection at each end of the cable.

The railing framework, which supports the cable systems, is available in a few different pre-engineered designs. Typically, there are all stainless steel but other types of materials and finishes are also available.

We offer completely welded systems that can be shipped to the job site and installed by a contractor of your choice. We also offer a component system which allows most of the erection to be done in the field.

Like our cable systems we have used a simple part number system for the railing frames as well.

  • FB1-2000 - 1/2" x 1 1/2" welded flat bar system
  • FB2-2000 - 3/8" x 1 1/2" welded flat bar system for cable SYSTEM 2300 only
  • FB3-2000 - 1/2" x 1 1/2" welded flat bar system
  • SP1-2000 - 1 1/2" square post component system
  • RP1-2000 - 2" welded round post system
  • UC1-2000 - 1 1/2" welded u-channel system for vertical cable systems only.

How to choose a railing system

  1. Browse the following pages and decide which cable system you like by referring to the part number.
  2. Choose which railing frame design you like according to its part number.
  3. Decide what cable diameter you would like to use.
  • 1/8" is typically only used for vertical cable systems.
  • 3/16" and 1/4" are typically used for horizontal cable systems.

Note: some cable systems are not compatible with certain railing frame designs. Please refer to the following pages of diagrams for this information.

Designing your own custom stainless steel cable handrail

If you prefer to design your own railing system for use with our cable systems instead of using one of our standard designs, please refer to the following information for important points of interest that will help to build a suitable railing system.

Cable assemblies require a significant amount of tension in order to minimize the deflection in the cable when a load is applied to them. The following is a list of items that will help insure your design will support our cable systems.

  1. Terminating points are the most important element since they ultimately support the tension in the cable. Terminating points for horizontal cable systems are the end post the fittings will terminate on. Terminating points for vertical cable systems are the top and bottom horizontal components of the railing framework.
    • Round post - use a minimum of a .145" wall thickness
    • Square post - use a minimum of .120" wall thickness
    • Angle post - use a minimum of a .375" wall thickness
    • Flat bar / plate - use a minimum of .5" thick plate. Also, flat plate material must be double up and bridged by material between the plates. A single flat plate will bend very easily under tension.
    • Wood post - use a minimum of a 4" x 6" pressure treated piece of lumber and fasten through the 6" dimension.
  2. Maximum length of the cable between the terminating points for a horizontal cable system should be about 40 feet. Longer lengths are achievable as long as the termination points are able to withstand the tension and any applied loads to the cable.

  3. Intermediate posts are for cable support only and do not require the same strength as the terminating point. However, the distance between them is very important. Intermediate post for a horizontal cable system help to reduce the amount of deflection in the cable when a person stands on the cable. Intermediate posts for a vertical cable system act more like a stiffener for the top and bottom horizontal component of the railing framework.

    Distance between intermediate posts for a horizontal cable system should not exceed 4 feet.

    Distance between intermediate posts for a vertical cable system should not exceed 3 feet. (This distance may vary depending on the type of material used for the top and bottom horizontal component of the railing framework.)

  4. Cable spacing should be at least 1" - to - 1 1/2" less than the local code. Therefore, a 4" code would require the cables to be 2 1/2" - to - 3" on center for both horizontal and vertical cable systems.

  5. Cable diameter for a horizontal cable system typically uses either a 3/16" or 1/4" diameter cable. Larger sizes up to 1/2" can also be used but are not as cost effective. Cable diameters for a vertical cable system are typically 1/8" and 3/16".

  6. Cable type should be a 1 x 19 or a 7 x 7 construction. 7 x 19 is not recommended due to the stretch.

  7. Turning corners with cable assemblies are done by either terminating the cables from opposite directions at the corner or by placing two posts in the corner and pass the cable from one post to the other. Bending a section of tubing on a minimum of a 3" radius and welding between two posts in the corner is also very effective. (This only applies to horizontal cable systems)

  8. Hole sizes in post will vary depending on if you choose to use swage or swageless fittings. If you choose to have the cable assemblies pre-manufactured from Seco, the hole diameter in the post will need to be large enough for the fitting to pass through. If you choose to install the fittings on the cable at the job site, you can minimize the hole diameters in the intermediate post by installing the fittings on the cable after the cables are passed through the intermediate post. Please refer to details on the specific hardware in the "cable fittings" section.
