The Simpson APHH610 Outdoor Accents Heavy Joist Hanger is a concealed-flange connector built to join 6x beams to girders in custom outdoor living structures where both structural reliability and visual appeal matter. Finished with ZMAX galvanization and a black powder coat, this heavy hanger is engineered for exterior framing and treated-wood applications, delivering clean straight-edged connections that integrate naturally with decorative deck and pergola builds. Part of the Simpson Outdoor Accents lineup, it pairs with the Mission Collection and Avant Collection to bring a cohesive, finished look to heavy timber framing projects.

Key Features

• Concealed-flange design with straight edges - keeps the hanger profile hidden within the connection for a cleaner, more finished appearance on exposed outdoor structures
• ZMAX galvanization with black powder coat finish - delivers extra corrosion resistance specifically rated for exterior environments and pressure-treated lumber, helping the hanger hold up over the long term without rust or degradation
• 12-gauge steel construction - provides the heavy-duty structural capacity needed for large-dimensional lumber connections in demanding outdoor framing applications
• Compatible with 6x10 and 6x12 member sizes - gives builders flexibility to use this hanger across a range of heavy timber framing scenarios without needing a different connector for each lumber dimension
• Complements the Outdoor Accents Mission Collection and Avant Collection - allows the hanger to serve as part of a coordinated decorative hardware system, tying together the aesthetic of the full structure (fasteners sold separately)
• Installs with specified Outdoor Accents and Strong-Drive fasteners - designed to work with a defined fastener schedule so builders can achieve rated connections with the correct hardware every time

Why This Product

• Structural performance meets decorative design - unlike standard utility hangers, this connector is built from 12-gauge steel while maintaining a refined black powder coat finish, so builders do not have to choose between holding power and appearance on visible outdoor builds
• Dual-layer corrosion protection for tough outdoor conditions - the combination of ZMAX galvanization and black powder coating goes beyond standard galvanized finishes, making this hanger well suited for exposed exterior framing and contact with treated wood where corrosion is a genuine long-term concern
• Fits within a complete decorative hardware system - the APHH610 is designed to coordinate with the broader Outdoor Accents Mission Collection and Avant Collection, allowing contractors and DIYers to achieve a unified, intentional look across connectors, fasteners, and hardware on a single project
• Versatile sizing supports multiple heavy timber applications - acceptance of both 6x10 and 6x12 members means this single hanger model can handle variation in lumber dimensions on the same job site, reducing the need to source and manage multiple connector SKUs
