The Simpson Strong-Tie CBST Column Base with ZMAX finish is designed for anchoring wood columns to concrete while providing protection in environments prone to moisture exposure. Its elevated standoff base helps prevent rot and decay by lifting the column 1" above concrete, while the ZMAX galvanized coating offers enhanced corrosion resistance for outdoor and treated lumber applications.

The CBST is cast for strength and engineered to handle demanding structural loads. Available in multiple sizes, it’s a go-to solution for both new builds and retrofit projects where code-compliant post anchoring is a must.

Key Features:

• 1" standoff keeps wood off concrete to reduce moisture damage
• Cast-in design provides high structural capacity and durability
• ZMAX galvanized coating protects against corrosion in treated wood or exterior environments
• Supports a variety of wood column sizes depending on selection
• Code-compliant solution for decks, porches, and more

Applications:

• Outdoor decks and patio roofs
• Porch posts and stair landings
• Pergolas and backyard pavilions
• Light commercial post-to-slab framing
• Any post-installed outdoor structure using pressure-treated lumber

Installation:

1. Place the CBST Column Base into wet concrete at the marked location before it sets.
2. Verify embedment depth and reinforcement per structural plans or local code.
3. After the concrete is fully cured, set the column into the base.
4. Fasten the wood post using Simpson Strong-Tie approved hardware through the side flanges.
5. For treated wood applications, ensure compatibility with ZMAX coated components.
