Adding a railing around a porch not only adds a level of safety, but makes a porch feel more like an outdoor room. There are so many options of style and material for columns and railings, one is really only limited by their imagination.
For our purposes here, when we say "railings" we are discussing the top and bottom materials used to hold the banister material between the two. The "banisters" make up the decorative material used to enclose your porch. Together with "columns" for roof support and posts for railings to attach to, you can create any style you choose to compliment your home's porch.
A variety of materials have been used for creating balustrades, railings, and columns. Everything from grapevines and limbs to stainless steel and glass. Truly, your imagination is your only limit. Sourcing the material you choose may be a bit more difficult if you step too far outside the box. However, if you can imagine it, you can probably make it happen.
