The Types segment classifies Hot‑Dip Galvanized Nails by shank geometry, head style, and coating thickness. Common shank designs include smooth, ring‑shank, and spiral‑shank, each offering a trade‑off between pull‑out resistance and driving torque; ring‑shank nails dominate the construction sub‑segment, capturing roughly 45 % of type‑specific sales. Head styles are split into flat, round, and truss heads, with flat heads preferred for finish work and truss heads for structural framing, together representing about 60 % of the market. Coating thickness varies from standard (≈55 µm) to heavy‑duty (≈85 µm), the latter commanding a premium price and serving high‑corrosion environments such as coastal infrastructure. Composite classifications, such as “self‑drilling” or “countersunk,” add further differentiation but occupy less than 10 % of total volume. By mapping these type attributes to end‑use requirements, analysts can quantify how product‑level specifications contribute to the broader market valuation.
