The Simpson Outdoor Accents Avant Collection ZMAX Black Powder-Coated Post Base for 10x10 is a structurally engineered and decoratively finished connector designed to anchor 10x10 nominal posts or columns securely to concrete. Built for outdoor applications including pergolas, patio covers, and other top-supported structures, this post base pairs a clean, simple aesthetic with dual-layer corrosion protection - ZMAX galvanization topped with a black powder coat - making it a dependable choice for exterior and treated-wood construction where both appearance and long-term performance matter.

Key Features

• Designed to meet stringent building codes for seismic or high-wind events - gives builders and homeowners confidence that the connection point is engineered for demanding structural environments, not just typical loads.
• Slotted for adjustability - allows for minor positional correction during installation, reducing the need for precise pre-placement and saving time on the job.
• 1-in. standoff from concrete surface - keeps the post end elevated above moisture, directly reducing the risk of post-end rot over the life of the structure.
• Fastener holes are slightly offset to help prevent fastener interference - allows all required fasteners to be driven cleanly without one screw blocking another, resulting in a full, code-compliant connection.
• Base made from 14-gauge steel; straps made from 12-gauge steel - heavier-gauge straps provide added strength at the most-stressed part of the assembly, while the base delivers solid, stable support underfoot.
• ZMAX galvanization with a black powder coat offers extra corrosion resistance for exterior and treated-wood applications - the two-layer finish stands up to moisture and the chemicals present in pressure-treated lumber, extending service life in outdoor settings.
• Straps feature ZMAX with a black powder coat for decorative applications - the exposed strap hardware presents a finished, intentional look that complements ornamental outdoor structures rather than detracting from them.
• Compatible with Outdoor Accents side plates (see APVBDSP) - optional side plates allow further customization of the post base appearance, letting the hardware blend seamlessly with a cohesive outdoor design scheme.

Why This Product

• Structural performance meets ornamental design - unlike purely utilitarian post bases, the Avant Collection connector is engineered to satisfy seismic and high-wind building codes while still presenting a clean, decorative profile suited to visible outdoor structures like pergolas and patio covers.
• Dual-layer corrosion protection built for the outdoors - ZMAX galvanization combined with a black powder coat creates a finish system specifically formulated to resist the moisture and chemical exposure common in exterior and treated-wood applications, helping the hardware maintain its integrity and appearance over time.
• Built-in rot prevention reduces long-term maintenance concerns - the 1-in. standoff is a design feature with a direct practical payoff: keeping the post end clear of standing moisture at the concrete surface is one of the most effective ways to extend the life of a wood post in an outdoor installation.
• Installation-friendly details throughout - from the slotted base that accommodates minor positioning adjustments to the offset fastener holes that eliminate interference when driving all required screws, the hardware is designed to make proper installation straightforward rather than frustrating.

Frequently Asked Questions

What fasteners are required to install the APVB1010?

Install with (8) STN22 Outdoor Accents hex-head washers and (8) SDWS22312DBB Outdoor Accents structural wood screws. Note that the structural screws, hex head washers, and concrete anchors are not included with the post base.

How does the APVB1010 help protect the post from moisture damage?

The post base features a 1-in. standoff from the concrete surface, which helps prevent direct contact between the post end and moisture, reducing the risk of post-end rot over time.

Is the APVB1010 suitable for high-wind or seismic regions?

Yes. The APVB1010 is designed to meet stringent building codes for seismic or high-wind events, making it appropriate for use in demanding structural environments.

What finish does the APVB1010 have, and why does it matter for outdoor use?

The post base features ZMAX galvanization combined with a black powder-coat finish. This dual-layer protection provides extra corrosion resistance, making it well-suited for exterior and treated-wood applications where exposure to moisture and chemicals is a concern.
