Steel Deck Framing

Juliet Taylor

Steel frame decks hold a very similar appearance to the average wooden deck, but they are much more sustainable. Steel decks are installed with interlocking joist and ledger systems which fortifies the structure against weather damage and corrosion. They are easy to work with and flexible enough to accommodate corners, bends and curves in the deck design.

Steel deck framing is the latest evolution in deck design and has quickly become a favourite over the traditional wood deck. This is because wooden decks are prone to rotting, breakage, warping, damage and splintering. The average wooden deck will need a full replacement about every 10-15 years. A large factor in the quick decline of wooden decks is their exposure to water – something that can rarely be avoided for an outdoor deck next to a pool.

Conversely, the average professionally installed steel deck will remain completely intact and safe for over 60 years. It will maintain the same like-new condition for at least 25 years and maintenance requirements are very low. Unlike wood, steel is not susceptible to moisture damage and high quality steel will rarely show any signs of age.

Advantages

Durability is the number one advantage for steel frame decks. Their 60+ year lifespan dwarfs most other materials such as timber (even treated timber cannot compete with a duration like this). They are also maintenance free, environmentally friendly, rust and corrosion resistant, and extremely strong. This makes steel decks one of the best material options for high-intensity areas such as near pools or in harsh outdoor weather conditions. Some other advantages to a steel deck include:

Disadvantages

Like any material, steel does come with its drawbacks. For those hoping to install a steel frame deck, here is what that means.

Steel framing design ideas: Plans, kits and manufacturers to inspire your steel framing system.

05. Steeldeck

One lesser-known option for the handy DIY-er is a steel decking frame kit. Purchasing prefab steel frames from quality Australian manufacturers like Steel-Deck ensures that you will be equipped with all of the metal materials you need, including steel joists, beams, span tables, foundational frames, posts, an installation guide and more.

Steel-Deck is compatible with all decking types, meaning that you can reap the benefits of a steel framed deck while maintaining the aesthetic appeal of timber or tile. The simple screw-fixed assembly makes setup a breeze. These prefab kits are also fairly affordable; for an instant free quote, fill out this prefab steel deck calculator.

04. Bunnings

Bunnings actually offers a custom made steel frame kit with bearers and joists cut to the desired length. The steel deck is delivered in kit form and is made from GALVASPAN fire resistant steel, which will prevent rot and warping for decades. It is a versatile design which could be used for mezzanines and other sub-floor applications as well as outdoor pool decks etc.

03. Picture frame decking

Picture frame decking is a beautiful new style which has recently emerged for both aesthetic and practical reasons. Having a clear border for the edge of the deck is safer, especially for children and those with impaired vision. A definitive edge to the deck helps people to conceptualize how much space they have and will avoid nasty accidents such as falling off the deck, slipping, or misjudging the stairs. (For a metal stair calculator, see here).

02. Platform

A platform deck is a raised deck which usually is not at ground level. There are many reasons for installing a platform deck rather than a simple deck that follows the shape of the ground. The most common is that the ground may not be level. If you live on a hill with a steep incline, installing a platform deck can be a much simpler task than trying to level the ground.

Another reason is the aesthetic appeal – platform decks are stylish, statement pieces that dominate a backyard space. Another reason someone might opt for a platform deck is the type of pool that they own. Often people will install steel frame decks around above ground pools to provide easy access and make the pool seem more natural in the backyardscape. Steel is undoubtedly one of the most pool-friendly construction materials, so a steel-framed deck is the perfect way to ensure durability in the years to come.
