A stair pan is a formed metal tray that holds poured concrete to create a step in a steel staircase. Stair Components & Systems manufactures stairpans for commercial and industrial projects, with standard profiles and custom dimensions available. Our pans are formed in square to fit fabricated stringer channels and reduce rework during assembly.

Pan stairs combine metal pans with concrete fill to form the walking surfaces of a staircase. The pan profile, material thickness, dimensions, and connections must match the project drawings. SCS offers Type 1, Type 2, Type 3, and Type 4 profiles, with configurations for different nosing and riser details.

Each profile is available with the following options:

• A: Combination tread and riser
• B: With sanitary cove
• C: With nosing
• D: With both nosing and sanitary cove

We manufacture the components needed throughout the stair flight: a starter riser at the beginning, combination tread and riser sections between steps, and a landing riser immediately before the landing. For the horizontal platform, see our stair landing pans.

Material options include hot rolled steel, cold rolled steel, stainless steel, and aluminum, along with pre-galvanized and hot-dipped galvanized options. Pans can be ordered with punched bolt holes, primer coating, and welded-on carrier angles. Specify the required material and finish when submitting your drawings.

For help preparing an order, our metal pan stair details guide explains the fabrication process and links to order forms and reference drawings. To request a quote, provide the profile, dimensions, material thickness, quantity, and any required fabrication options.

Frequently Asked Questions

What are pan stairs?

Pan stairs are steel stair assemblies with formed metal pans that receive concrete fill. The pans form the individual steps and connect to the supporting stair structure.

What do the A, B, C, and D stairpan options mean?

The letters identify details within each SCS stairpan profile. A is the combination tread and riser configuration. B includes a sanitary cove, C includes nosing, and D includes both. Select the configuration shown in your project drawings.

Can stairpans be made to custom dimensions?

Yes. SCS manufactures stairpans in standard configurations and to custom dimensions. Submit the required profile, tread and riser dimensions, material, thickness, and quantity using the appropriate order form or project drawings.

Can carrier angles be welded to the stair pans before shipping?

Yes. Welded-on carrier angles are an available fabrication option. Include their dimensions and connection requirements with your stairpan order so the assembly matches the stair design.
