The Simpson CB1010HDG CB Hot-Dip Galvanized Column Base for 10x10 by Simpson is built to securely connect posts to concrete foundations across a wide range of lumber, glulam, and engineered wood product sizes. Whether installed cast-in-place or wet-set into concrete, the base plate sits flush with the concrete surface to provide full post bearing beneath the column. Fabricated from heavy 3-gauge steel with a hot-dip galvanized finish, this column base is engineered for the high structural values and rugged performance required in demanding exterior and treated-wood applications.

Key Features

• Increased uplift resistance for wind or seismic loading - helps protect the connection between post and foundation during high-stress weather or seismic events, giving builders greater confidence in structural integrity.
• Bolt hole locations meet code-required spacing for optimal capacity - ensures the connection achieves its full rated load capacity and simplifies the inspection and permitting process.
• Made from 3-gauge steel - the heavy gauge construction provides the rigidity and load-bearing strength needed for large-column applications where standard-gauge hardware falls short.
• Hot-dip galvanized finish - delivers enhanced corrosion resistance for exterior environments and treated-wood applications, where standard coatings may break down over time and compromise the connection.
• Cast-in-place or wet-set installation - two compatible installation methods offer flexibility on the jobsite, with the base plate sitting flush with the concrete surface for full post bearing in either case.

Why This Product

• Engineered for demanding structural applications - the combination of 3-gauge steel construction and a design optimized for high structural values makes this column base well suited for posts and columns where performance cannot be compromised.
• Built-in corrosion protection for outdoor and treated-wood use - the hot-dip galvanized coating goes beyond standard finishes, making this base a reliable choice for exposed exterior columns and pressure-treated lumber installations.
• Versatile compatibility with multiple wood products - designed for use with solid lumber, glulam beams, and engineered wood products at a nominal 10x10 column size, this base supports a broad range of construction methods and materials.
• Code-conscious design for straightforward approvals - bolt hole spacing that meets code-required placement, combined with uplift resistance for wind and seismic loading, helps support code compliance on projects where structural connections are subject to review.

Frequently Asked Questions

How is the CB1010HDG installed into concrete?

The CB1010HDG can be installed using either a cast-in-place or wet-set method. In both cases, the bottom of the base plate sits flush with the concrete surface to ensure full post bearing beneath the column.

What hardware is required to install the CB1010HDG?

Installation requires (2) 3/4-in. diameter HDG machine bolts to securely fasten the column base.

Why is the hot-dip galvanized finish important for this column base?

The hot-dip galvanized (HDG) coating provides enhanced corrosion resistance, making the CB1010HDG suitable for exterior environments and applications involving treated wood, where standard finishes may degrade over time.

What types of posts or columns is the CB1010HDG compatible with?

The CB1010HDG is designed for use with a wide range of lumber, glulam, and engineered wood products at a nominal column size of 10x10, accommodating both standard and engineered wood applications that require high structural performance.
