Product Description
Simpson CB46HDG CB Hot-Dip Galvanized Column Base for 4x6 by Simpson Strong-Tie is engineered to connect posts to concrete foundations across a wide range of lumber, glulam, and engineered wood product sizes. This column base is either cast-in-place or wet set into the concrete, where the bottom of the base plate sits flush with the concrete surface for full post bearing. Constructed from heavy-duty 7-gauge steel with a hot-dip galvanized finish, the CB46HDG is ideal for columns that require high structural values and rugged, long-lasting performance in demanding exterior and treated-wood environments.

Frequently Asked Questions
- What installation methods are compatible with the CB46HDG?
- The CB46HDG is designed to be either cast-in-place or wet set into concrete. In both methods, the bottom of the base plate sits flush with the concrete surface to provide full post bearing.
- What type of steel and finish does the CB46HDG use, and why does it matter?
- The CB46HDG is fabricated from 7-gauge steel and features a hot-dip galvanized (HDG) finish. This coating provides extra corrosion resistance, making it well suited for exterior environments and applications involving pressure-treated wood where corrosion is a concern.
- What fasteners are required to install the CB46HDG?
- Installation requires (2) 5/8-in. diameter HDG machine bolts. The bolt hole locations are positioned to meet code-required spacing for optimal load capacity.
- Is the CB46HDG suitable for high-load structural applications?
- Yes. The CB46HDG is engineered for columns that require high structural values and rugged performance, including increased uplift resistance for wind or seismic loading, making it appropriate for demanding structural applications.
