FAQ

Aluminum Railing Questions

Common questions about aluminum rail systems for decks, porches, and stairs.

How much does aluminum railing cost?
Hart Series aluminum railing ships as complete boxed kits, so pricing is per kit by length and height rather than per linear foot. Contractors get wholesale aluminum railing pricing from NMI Fence — request a quote for deck, porch, or stair railing.
Is aluminum railing cheaper than wood?
Over the life of the install, yes. Powder-coated aluminum railing never rots, warps, or needs repainting like wood, so a higher upfront cost is offset by near-zero maintenance and a limited lifetime warranty.
Can you cut aluminum railing to size?
Yes. Hart Series rails can be cut to length on site, and the kits include level, stair, and swivel brackets so you can fit deck, porch, and stair runs at standard or custom angles.
What's the difference between an aluminum rail and aluminum railing?
The terms are used interchangeably. An aluminum rail or aluminum railing both refer to the complete rail system — top rail, bottom rail, balusters, posts, and brackets. Hart Series is a full aluminum rail system for decks, porches, and stairs.
Does Hart Series work for deck, porch, and stair railing?
Yes. The same boxed system covers level deck and porch railing plus 32°–36° stair railing, using self-centering brackets and 36" or 42" height options to meet code.
