Product Description
The Simpson HPA28 32-1/2 in. Heavy Purlin Anchor is an engineered connector from Simpson Strong-Tie built to deliver dependable wood-to-concrete and wood-to-concrete block connections that satisfy code requirements. Formed from 10-gauge steel with a G90 zinc galvanized finish, this purlin anchor is designed to connect roof purlins to concrete walls with confidence, making structural projects easier to build while producing stronger, safer results. Simpson Strong-Tie connectors are engineered and tested to perform and are manufactured to the highest quality standards.
Key Features
- 32-1/2 in. strap length - provides the reach needed to make solid wood-to-concrete and wood-to-masonry connections across typical purlin anchor applications
- 10-gauge steel construction - delivers heavy-duty strength and rigidity so the anchor holds up under the structural loads expected in roof purlin connections
- G90 zinc galvanized finish - offers extra corrosion resistance, helping the anchor maintain its integrity in demanding or moisture-prone installation environments
- Minimum embedment depth of 6 in. for GFCMU and concrete - meets code-defined anchoring requirements, giving builders and inspectors a clear, reliable benchmark during installation
- Installs with 10d common nails - uses a widely available fastener so there is no need to source specialty hardware to complete the connection
Why This Product
- Code-compliant wood-to-concrete connections - the HPA28 is specifically engineered to satisfy code requirements for wood-to-concrete and concrete block connections, reducing guesswork and supporting smooth inspections on structural builds
- Engineered and tested for performance - Simpson Strong-Tie designs and tests its connectors to verified performance standards, so builders can rely on this anchor to perform as specified rather than estimating capacity
- Built-in corrosion protection for long-term durability - the G90 zinc galvanized coating goes beyond basic protection, making this purlin anchor a practical choice for installations where moisture exposure is a concern over the life of the structure
- Straightforward installation with common fasteners - compatibility with standard 10d common nails and a clearly defined 6 in. embedment depth means installation follows a simple, repeatable process that saves time on the job
