Metal Framing
Metal framing changes the way a deck performs from the ground up.
As more projects move toward Class A assemblies, WUI-conscious construction, and longer-lasting exterior systems, builders are paying closer attention to what sits beneath the decking. Traditional pressure treated wood framing still has its place, but for projects prioritizing fire resistance, dimensional stability, and long-term durability, metal framing offers a different level of performance.
At TimberTown, we supply aluminum framing by TimberTech and steel framing by Fortress for residential, commercial, rooftop, and elevated deck applications. These systems stay straighter over time, resist many of the movement issues common with treated lumber, and pair well with many modern Class A-rated decking and railing systems.
The result is a cleaner structure, tighter finish details, and a framing package designed to support the level of materials being installed above it.
For builders and designers navigating evolving WUI requirements or simply looking to build a better-performing deck system, metal framing has become an important part of the conversation.
TimberTech Aluminum Framing is a complete system of components, from joists and posts, to ledgers and beams, all working together to create the best, longest-lasting deck. Aluminum Framing is compatible with every TimberTech Decking and Railing collection.
