Product Description
The Simpson Outdoor Accents Avant Collection ZMAX Black Post Base Side Plates are decorative steel plates designed to attach to the bottom of a post or column, delivering a clean and finished appearance at the base of an installed post base. Part of Simpson's Avant Collection, these plates feature straight edges and a timeless architectural profile that complements custom outdoor living structures including pergolas, patio covers, and other top-supported builds. Constructed from 12-gauge steel with a ZMAX galvanized and black powder coat finish, these side plates are built to handle the demands of exterior environments and treated-wood applications where moisture and corrosion are ongoing concerns.
Key Features
- Complements the Outdoor Accents APVB decorative post base - pairs directly with the matching Simpson post base for a cohesive, polished look at the base of any post or column
- Designed for nominal 10x and 10x rough lumber - fits both standard dimensional and rough-cut 10x posts, giving you flexibility across common framing conditions
- Made from 12-gauge steel - provides the structural rigidity needed to maintain a clean, flush appearance over time without warping or sagging
- ZMAX galvanization with a black powder coat finish - delivers extra corrosion resistance for exterior applications and treated-wood contact, extending the life of the hardware in harsh outdoor conditions
- Straight-edge Avant Collection styling - the clean, geometric profile blends naturally with modern pergolas, shade structures, and outdoor living spaces for a refined finished look
- Installs with Outdoor Accents-matched fasteners - designed for use with STN22 hex-head washers and SDWS22312DBB structural wood screws (sold separately), keeping the hardware aesthetic consistent throughout the assembly
Why This Product
- Purpose-built for a finished, professional appearance - rather than leaving the base of a post base exposed, these decorative side plates close off the transition between post and base with a straight-edge profile that looks intentional and well-crafted on pergolas, patio covers, and similar outdoor structures
- Engineered for long-term exterior performance - the combination of 12-gauge steel construction, ZMAX galvanization, and a black powder coat finish means these plates resist corrosion in the demanding conditions that come with outdoor and treated-wood applications, not just on installation day but over the life of the structure
- Designed as a true system component - these plates are specifically matched to the Outdoor Accents APVB decorative post base and coordinating Outdoor Accents fasteners, so every visible element at the column base shares the same black finish and design language for a cohesive result
- Broad compatibility for common post sizes - support for both nominal 10x and 10x rough lumber means these plates work across a wider range of post and column stock, reducing the need to source specialty hardware for rough-cut timber builds
