Joist Hangers

Joist hangers are steel connectors that secure joists to a ledger board or beam, creating strong, reliable deck framing and floor systems. By holding joists tight and square, they improve load transfer, reduce twisting and squeaks, and help projects meet building code requirements. They also speed up framing, keep spacing consistent, and make retrofits or repairs cleaner and safer.

Choose from face-mount hangers, top-flange hangers for flush beams, concealed-flange models for a clean look, heavy-duty and double-shear hangers for greater loads, and skewed or sloped options for angled framing. Specialized hangers exist for LVL, PSL, and I-joists, including models with web stiffeners. Popular materials and finishes include G90 galvanized, ZMAX/high-corrosion coatings, hot-dip galvanized, and stainless steel (304/316) for coastal, marine, or poolside environments. Match the coating to pressure-treated lumber (ACQ, CA) and local exposure to prevent corrosion.

Sizing matters. Select a hanger that matches the joist width and depth (2x6, 2x8, 2x10, 2x12, and engineered sizes) and verify the load rating and uplift requirements. Always use approved fasteners: joist hanger nails or structural connector screws of the specified diameter and length. Avoid drywall or decking screws. Fill all required fastener holes to achieve the published capacity.

Quick installation tips:
- Mark layout on the ledger or beam and prefit the hanger.
- Tack the hanger level, then install all specified nails or screws.
- Seat the joist fully; there should be no gap between joist and hanger.
- Use corrosion-matched fasteners and add hurricane ties if uplift is a concern.
- Check ICC-ES reports and local code before you build.

Top brands like Simpson Strong-Tie and MiTek offer a wide range of deck framing connectors with clear load tables and code approvals. Filter by joist size, material, coating, flange style, skew/slope, and price to find galvanized joist hangers, stainless steel joist hangers, face-mount hangers, and heavy-duty options that keep your deck framing strong, safe, and code-compliant.
