Metal and Wood Straight Staircases

Pricing for custom metal staircases varies based on stringer configuration, dimensions, tread selections, and finish specifications.

The ideal material depends on architectural aesthetics, foot traffic, and installation environment. Steel, aluminum, and stainless steel stringers offer high structural strength, durability, and support for wide spans. Pairing metal stringers with wood treads provides structural integrity alongside organic warmth, while weather-resistant finishes like galvanized steel and treated wood ensure lasting performance in exterior applications.

Acadia Stairs manufactures three primary straight stair styles: single stringer, double stringer, and side stringer systems. Single stringers feature a heavy-duty center beam for an ultra-open floating effect. Double stringers use two parallel support members under treads for wider spans exceeding 48 inches. Side stringers place supports along the outer edges to accommodate various tread types.

Exterior projects utilize weather-resistant materials and protective treatments, including galvanized steel, powder-coated finishes, and treated wood, designed to protect stringers and treads from outdoor exposure, moisture damage, and long-term environmental wear.

The single stringer straight staircase features a heavy-duty center beam engineered to handle 300 lbs per tread. It incorporates a triangular frame beneath laser-cut treads for high rigidity and stability, supporting widths up to 42 inches without requiring supplemental under-tread supports in standard configurations.

Yes, our straight stair systems are designed to meet applicable local and national safety standards for residential and commercial applications. Side stringer options feature riser space limiters maintaining gaps under 4 inches, while single and double stringers are engineered around standard tread depth, riser height, and required load capacities.
