Decorative Post Bases

Decorative Post Bases: Style, Strength & Structural Support

Decorative post bases are the foundation of any outdoor structure, literally and visually. Simpson Strong-Tie’s Outdoor Accents post bases combine architectural design with code-compliant performance, offering a bold, black powder-coated finish that stands up to the elements and complements your outdoor framing.

Ideal for pergolas, pavilions, porches, fences, and backyard structures, these post bases are made to anchor your build with unmatched durability and style. Whether you're a professional contractor or tackling a DIY project, these bases bring both form and function to your foundation.

What Makes Them Decorative?

Unlike traditional galvanized post bases, decorative post bases are designed to be seen. The black powder-coated finish adds a refined, modern aesthetic to the bottom of your vertical framing. With wrapped or elevated designs, they not only look great, they protect the post from ground contact and moisture.

Most models in the Outdoor Accents line also include matching hardware or integrate seamlessly with Simpson’s hex-head fasteners and washers, ensuring a consistent visual throughout your structure.

Engineered for Outdoor Use

All Simpson decorative post bases are manufactured with ZMAX® galvanized steel for high corrosion resistance, then finished with a durable black powder coat for added weather protection and architectural appeal. Many bases include a 1-inch standoff from concrete, which reduces the risk of rot and extends the life of your wood posts.

Where to Use Decorative Post Bases

• Pergolas and pavilions
• Deck framing and porch posts
• Fence systems and privacy walls
• Outdoor kitchens and bar structures
• Gazebos and custom timber frames

Installation Notes

Install your decorative post bases with Simpson Strong-Tie fasteners to maintain structural integrity and corrosion resistance. Be sure to verify base sizing for your post dimensions (4x4, 6x6, 8x8, etc.) and use concrete anchors or screws as required. For concealed and retrofit styles, follow installation guides closely for maximum load performance and code compliance.
