Q: How many balusters do I need per foot?
A: Most codes require spacing ≤4", typically needing 3 balusters per linear foot of railing.
Q: Can I mix metal and wood stair parts?
A: Yes, many designers combine metal balusters with wood handrails for contemporary looks.
Q: What's the lead time for custom stair parts?
A: Standard products ship in 2-4 weeks; custom designs may require 6-8 weeks for production.
Q: How do I maintain wrought iron stair parts?
A: Annual cleaning with mild soap and touch-up painting prevents rust. Powder-coated options require less maintenance.
