Which Railing Is Best for Outdoors?
Stainless steel is the best railing for outdoors. It won’t rot, warp or need staining like wood, and it holds up to rain, sun and freeze-thaw better than painted or powder-coated steel. Our AXIA stainless steel railing works on decks, porches, balconies and outdoor stairs, with rod, cable or glass infill.
Outdoor Railing Materials Compared
| Material | Upkeep | How it holds up outside |
|---|---|---|
| Stainless steel | Wipe it down now and then | Best. Won’t rot or rust through, and keeps its look |
| Aluminum | Low | Good. Light and rust-free, but dents and can feel flimsy |
| Composite or vinyl | Low | Good. Can fade, and the look is limited |
| Wood | High: stain and seal every year or two | Fair. Rots, warps and splinters without upkeep |
| Painted or powder-coated steel | Medium: touch up chips | Fair. Can rust anywhere the coating chips |
Why We Recommend Stainless Steel
- It lasts. Stainless steel doesn’t rot, and it doesn’t depend on a painted coating to keep rust away.
- The right grade. AXIA parts come in 304 or 316 stainless, depending on the part. 316 is the marine grade, the better pick near pools, salt water and the coast.
- Low upkeep. No sanding, staining or repainting. Just clean it now and then.
- Modern look. Clean lines, with cable, rod or glass infill to keep the view open.
- No welding. AXIA parts fit together with screws, rivets and fittings, so you get a custom look without paying for custom fabrication.
Mounting Outdoor Railing
AXIA posts mount to wood decks with wood screws or to concrete with concrete anchors. For concrete porches and steps, see how to anchor a metal railing in concrete.
