This is a discussion/cookbook for those homeowners who are experienced enough to install their own outdoor railings.
1. Materials for outdoor railings
The most common type of outdoor railing is for decks and walkways. The materials choices are: stainless steel, painted steel, wrought iron, aluminum, brass, and wood. All types of wood will decay after 10-20 years. Wrought iron will rust outdoors. Painted steel will need to be re-painted every 5-10 years.
For the choices which require little maintenance, stainless steel will last longer than brass outdoors and does not require as much work to touch up if it tarnishes. One’s final choice needs to combine aesthetic considerations with longevity. The remainder of this blog centers around the choice of stainless steel, which seems most logical for outdoor railings.2. Building codes
It is easiest to replace an existing railing with a new one in the same place with the same design. If creating a new railing, you need to investigate the local building codes to see what is required. If your existing railing is wobbly or you suspect it does not meet codes, an investigation is still warranted.
Most codes require posts to be a maximum of 6 feet apart. Posts should be securely attached to framing members of the deck/stairway. Typically bolts or lag screws are used.You should also be aware of the International Building Code. Make sure that the railings you purchase comply with it.
3. Height choice
The height is generally one of two different standards: 42 inches for commercial or 36 inches for home. In some cases the homeowner may want to choose a 42-inch rail where child safety is an issue or where there is a large drop to the ground (the extra height will ‘seem safer’).
4. Buying the railings
You will want to buy railings from a manufacturer who includes stainless railings in their line. There are many choices, and probably the quickest way to find them is to search for ‘steel railings’ using Google. Most companies ship modular parts which are assembled on-site. The degree of assembly required varies widely. One example company who sells complete modules that require little assembly is www.SteelStudioUSA.com.
5. Inspection and approval
If you are simply repairing an existing railing with an identical design, generally a building inspection is not required (however may be a good idea anyway). If there are design changes or new sections involved, an inspection by your local city building office is required. Be sure to test the finished railing to make sure it is sturdy in all sections.
