Last updated: April 2026 dataProduced by slitting and stretching a solid metal sheet rather than weaving or welding wire, expanded metal has a distinctive diamond-pattern aperture and integral strand structure that sets it apart from all wire-based mesh in heading 7314. A single 10-digit line (7314500000) covers the full range of iron and steel expanded metal, from lightweight lath used in plastering to heavy-duty grating for industrial flooring and safety barriers. Mexico is the leading supplier, with China and Canada also significant; the product is subject to Section 232 steel tariffs, and the manufacturing process — which occurs entirely in the country of production — makes origin determination straightforward. Specifiers should note that strand thickness, diamond dimensions, and surface treatment (plain, galvanized, or painted) are the key commercial variables.

Expanded metal is formed from a single sheet by simultaneous slitting and stretching — there are no separate wires or weld points. This manufacturing distinction places it exclusively under 7314500000 rather than any of the welded or woven wire subheadings. The duty rate and any applicable trade-remedy exposure may differ between the two product types, so confirming the production method with the manufacturer is essential before filing entry.
Construction (plaster lath, stair treads, walkway grating), industrial safety (machine guards, ventilation covers), and architectural design (facade panels) are the primary end-use sectors. Construction-grade product is highly price-sensitive, favoring nearby suppliers like Mexico for freight efficiency, while architectural and precision-grade expanded metal may be sourced from specialized producers regardless of geography.
