The Simpson Strong‑Tie HUC ZMAX® Concealed‑Flange Joist Hanger is a heavy‑duty connector designed to support wood joists on the face of a ledger, header, beam, or support while providing a clean, concealed header flange for exposed applications. Its ZMAX® G185 galvanized finish delivers enhanced corrosion resistance for treated lumber and outdoor conditions, making it a smart choice for deck framing, porch roofs, and structural platforms where durability and visual quality matter.
Constructed from 14‑gauge steel, HUC hangers are load‑rated and code compliant, engineered to carry joists securely across a range of nominal lumber sizes. The concealed flange design keeps mounting fasteners hidden from view and helps maintain a neater profile on exposed deck framing.
Key Specifications:
Type: Concealed‑flange face‑mount joist hanger
Material: 14‑gauge steel with ZMAX® galvanized coating for corrosion resistance in exterior and treated‑wood applications
Joist Size Compatibility: Available in multiple nominal sizes such as 4×6, 4×8, 4×10, 6×6, 6×12, 4×12 (model‑specific)
Appearance: Concealed header flanges reduce visible hardware at the deck edge
Benefits for Contractors and Homeowners: This joist hanger simplifies secure joist support while delivering a more refined look on exposed framing. The ZMAX® galvanization extends service life in moisture‑prone environments, and the heavy‑duty design supports reliable structural performance with optimum fastener placement. Whether used for residential decks, outdoor structures, or commercial framing, the HUC ZMAX hanger provides durable, code‑aligned support where joists meet headers or beams.
