NMFC 37245 - Metal Spiral Stairs | Class N/A

To find the correct freight class for your shipment:

1. Decide on assembled vs. knocked-down. Oversized assembled spirals often exceed standard LTL height or diameter; disassemble into center column, treads, and landings to fit palletized LTL.
2. Package by component: block and crate the center column, nest and band treads with edge protectors, wrap with foam and corrosion inhibitor for steel. Use 4-way skids sized to prevent overhang.
3. Document clearly on the BOL: “Stairs, circular/spiral, metal (non-aluminum) – NMFC 37245,” include piece count, largest diameter, longest length, and photos or shop drawings to reduce inspections.
4. Plan handling: mark center of gravity, add fork pocket clearance, and avoid mixed loose parts. For heavy landings, request docks or forklifts at both ends instead of liftgate service.

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

• Right-sized packaging lets you move parts LTL instead of dedicated flatbed, cutting transport costs while meeting jobsite schedule needs.
• Detailed descriptions tied to NMFC 37245 minimize reclass and reweigh charges, improving rate predictability and avoiding rebills.
• Damage control through proper blocking, nesting, and corrosion protection reduces repainting and fit-up rework, accelerating installation.
• Clear componentization (column, treads, landings) speeds carrier handling and claims resolution, protecting margins on custom fabrications.
