NMFC 36630 - Door/Window Wire Grilles | Class N/A

To find the correct freight class for your shipment:

1. Palletize grilles flat with a rigid backer (OSB or plywood) to prevent bowing, add edge protectors, and band through the mesh to stop shifting.
2. For tall or skylight guards, build a light wood crate with corner blocking; cap sharp wire ends with plastic tips, then stretch-wrap and strap.
3. Nest multiple grilles face-to-face with slip sheets and staggered crossbars to reduce overall height; mark piece count and dimensions on labels.
4. When a carrier requests class detail, cite NMFC 36630 and list material (iron/steel wire), finish (galvanized or powder-coated), and packing method to speed review.

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

• Damage prevention—less bent wire and fewer OS&D claims—keeps project timelines and installation crews on schedule.
• Nesting and tight bundling cut cube, which can lower LTL rates and minimize pallet count and accessorials.
• Clear NMFC reference with packing details helps avoid reclass disputes and inspection delays when no class is specified.
• Non-hazardous metalwork widens carrier options and simplifies paperwork, supporting faster tender-to-pickup cycles.
