Hello and thank you for your question. A cable railing can be custom made with steel powder coated angles by a steel worker or be purchased from a kit. A popular product is Carl Stahl Decor Cable. Try a quick internet search and see what catches your eye; there should be a handful of companies to assist you.

As far as the stairs, we typically work with a stair manufacturer and/or local millworker to ensure a structurally stable stair. They can help you select a species of wood and perhaps detail the connections. We hope the helps!
