The TimberTech Aluminum Framing Installation Guide (PDF) provides comprehensive, step-by-step instructions for installing TimberTech’s high-strength aluminum framing system. This guide covers everything from footing preparation and post layout to beam installation, joist spacing, stair framing, bracket placement, and deck-board fastening—making it an essential resource for builders using TimberTech decking on a metal substructure.
The guide begins with foundation requirements, including footing types, frost-line considerations, and how to correctly secure post bases to prevent uplift or lateral movement. Installers are walked through setting aluminum posts, attaching post caps, and installing beams using post-to-beam half brackets and beam clips. Diagrams show how to align beams flush with posts, splice beams over posts, and support double-beam configurations.
Ledger installation includes drilling patterns for LedgerLOK® fasteners, waterproofing requirements, and guidance for matching ledger height to the installed beam elevation. Joist installation instructions detail how to hang rim joists and field joists using joist hangers, tall and short L-brackets, uplift keys, and joist spacers—ensuring correct spacing at 12″ or 16″ on center. The manual also includes options for non-rectangular layouts using 135° and adjustable angle brackets.
Stair installation is a major focus of this guide. TimberTech aluminum rim joists double as stair stringers, allowing for strong, lightweight, consistent 34° stair geometry. The manual includes full instructions for cutting stringers, attaching Stair Landing L-Brackets to both deck and foundation, installing stair tread brackets, inserting front and back stair treads, and meeting rise/run requirements. Diagrams illustrate correct orientation of labeled brackets (“Top Left,” “Top Right,” “Landing”) to avoid misalignment.
Additional sections cover deck-board installation using Cortex® Driller screws, proper screw placement, pre-drilling at miters and butt joints, preventing metal chip buildup, leveling boards with joist-tape shims, and installing plugs flush. The final pages provide guidance for picture-frame borders, mid-span blocking, railing post attachment, and rooftop considerations.
