नवीनतम कंपनी ब्लॉग के बारे में Simpson Strongtie Avant Gable Plates Strengthen Outdoor Timber Structures

Simpson Strong-Tie’s Outdoor Accents line includes the Avant series, a family of decorative structural hardware intended for custom outdoor wood construction. The line combines load-bearing reinforcement with a clean, modern profile, and its gable plates are designed to connect a wood beam to three angled wood supports. The plates are intended to serve both structural and visible design roles in exterior timber framing.

Avant series design approach

The Avant series is part of the Outdoor Accents decorative hardware range. Unlike some other products in the line, Avant plates use straighter edges and a more modern profile intended to suit contemporary architecture. The gable plates serve both decorative and structural roles, reinforcing the connection between a wood beam and three angled wood supports in an outdoor timber frame.

Product specifications and selection

Simpson Strong-Tie offers the gable plates in configurations intended for different lumber dimensions and roof pitches. Selection should be based on the size of the framing members and the slope of the roof.

Suitable lumber Roof slope options
6x and larger lumber 6:12, 8:12 and 12:12
4x lumber 12:12

Models are available for 6x and larger lumber in 6:12, 8:12 and 12:12 roof slopes, while 4x lumber is matched to a 12:12 slope. The specifications are intended to help builders align connector size with the structural drawing and roof geometry.

Material and weather performance

The Avant gable plates are made from 12-gauge steel and are intended to provide structural strength in exterior applications. The finish combines ZMAX galvanized steel with a black powder coating.

That dual finish is designed to improve corrosion resistance across outdoor conditions and to support long-term use with treated wood. For projects in highly corrosive environments, the suitability of the finish should be confirmed during structural planning.

Installation considerations

Installation calls for Outdoor Accents structural screws and hex-head washers. The required fasteners are generally sold separately from the connector plates.

During installation, screws should pass fully through the plate and into the wood to achieve the load capacity assumed in the design. The plates are intended to be installed with the specified fasteners rather than generic hardware.

Frequently Asked Questions

Are mounting screws included with the Avant gable plates?
No. The required fasteners, including Outdoor Accents structural screws and hex-head washers, are sold separately. The manufacturer recommends using its matching components to support connection performance.
How should the correct plate size be selected?
Selection depends primarily on lumber thickness—4x or 6x and larger—and roof slope. The plate should match the framing member and the slope listed in the project drawings, such as 6:12, 8:12 or 12:12.
Can the plates be used with all exterior wood products?
The ZMAX galvanized steel and black powder coating are intended for outdoor and treated-wood applications. In highly corrosive settings, a structural engineer should be consulted to confirm the required corrosion protection level.
