Material Guide


Deck framing refers to the process of constructing the structural framework that supports a deck. This involves measuring and cutting the necessary lumber, securing it in place with hardware such as joist hangers and screws, and ensuring that the frame is level and square.

Framing Material


Proper deck framing is essential to ensure that the deck can withstand the weight of furniture, foot traffic, and other loads without sagging or collapsing.

Value Treated Framing

By utilizing treated wood for the deck framing, it ensures a longer lifespan and reduces the risk of structural damage. The treatment process involves applying chemicals to the wood, which penetrate deep into the fibers, providing long-lasting protection.

This deck framing undergoes a meticulous process known as kiln drying after being treated. This method ensures that the wood used in the deck framing is thoroughly dried in a controlled environment, eliminating excess moisture and enhancing its durability.

Premium Steel Framing

Steel deck framing is a structural system that utilizes steel beams, joists, and posts to support and create a sturdy foundation for outdoor decks. This type of framing offers numerous advantages over traditional wood framing, including increased durability, resistance to rot and pests, and enhanced stability.

Everything you need to know about framing materials.

Deck joist spacing should never exceed 16″ on center (with the exception of MAX deck boards, which allow for maximum 24″ on center). For a more rigid feel, 12″ or less may be preferred.

While all deck joists should be pressure-treated wood, PT wood now is not the same as 30 years ago. For example, because of changes in preservatives over time, today’s wood decks are built with the wood posts above ground (not making ground contact to reduce moisture content) and attached to concrete footers

Screws are superior for laying down the decking. They hold things flush better and have a better fastener/tensile strength, which keeps boards from popping up over time. However, unless you use more expensive structural screws you need to use nails for structural elements and joists.

It is made of High-Density Polyethylene (HDPE) reinforced with fiberglass
(Advantex® FiberglasTM by Owens Corning) for outstanding strength and durability.

Steel framing offers numerous advantages over wood. It’s just as easy to install, and is compatible with all deck boards, but unlike wood, steel delivers straight, uniform pieces engineered for longer spans, and is naturally fire and insect resistant. Fortress® steel framing is also backed by a 25-year warranty and won’t rot or sustain moisture-damage like wood. Steel is also sustainable, which makes it a great option for environmentally conscious builders and homeowners.
