NMFC 37257 - Iron/Steel Staircases | Class N/A

To find the correct freight class for your shipment:

1. Break long runs into modules—stringers, treads, and landings—and band them to custom skids; add cross‑bracing so assemblies can’t rack in transit.
2. Protect finished surfaces with foam edge guards and stretch wrap, then crate or frame with 2x4s and plywood; mark lift points and center of gravity.
3. Quote precisely by measuring the longest section and the crated footprint; note non‑stackable items and request jobsite or residential delivery when applicable.
4. Match equipment to the build: send crated modules via LTL, use flatbed for one‑piece flights; specify straps‑only if paint or powder coat could be damaged.

Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.

• Avoid accessorials by designing sections under common LTL thresholds (e.g., 96 inches length) to reduce overlength and special handling fees.
• Cut damage and rework with rigid bracing of stringers and isolated rail kits, helping crews install faster with fewer field fixes.
• Improve jobsite efficiency by labeling sequence and orientation (e.g., Flight A, Landing L1), minimizing unload time and staging confusion.
• Non‑hazardous status broadens carrier options and helps stabilize rates during busy construction seasons.
