What Gauge Is Metal Decking

Metal decking typically has a ribbed or corrugated profile that is achieved through a process called roll forming.

What gauge is metal decking. So inversely the smaller the gauge number the thicker the metal. Manufacturers express the thickness of metal panels as their gauge with 22 gauge being the thickest and 29 gauge the thinnest of traditionally sold metal roof and wall panels. Steel gages can range from 10 to 28 depending on the product and most deck types have a yield strength of at least 33 ksi. Discover a smarter steel framing system designed by deck builders for deck builders.

With metal deck the smaller the gauge number the thicker the steel. Each gauge represents a nominal decimal range. Why gauge thickness matters. Steel decking is used in many applications but is particularly well suited to roofing and flooring.

Vulcraft manufactures many different types of deck including roof deck floor deck composite floor deck and cellular deck. Metal decking is most commonly 16 18 20 and 22 gauge in thickness. Gauges for form decks vary from 22 to 16 gauge 20 18 gauges are the most common. Several deck finishes are available the most common being galvanized g60 z180 or g90 z275.

The total solution in steel deck framing. Our powder coated finish provides increased corrosion resistance and a more finished look. 20 ga 18 ga 16 ga. The metal deck gauge is a unit of measurement that refers to the thickness of the steel.

Normally used for spans of 4 10 with slabs of 4 8 of concrete and are used to create a composite action between the steel concrete. Depending on the profile type we carry the following gauges. Metal decking is used in a wide variety of commercial and industrial applications. The interlocking joist and ledger system lets you build sturdy safe decks with less effort.

They are typically available in galvanized g60 or g90 and can be ordered in phosphatized prime painted. The larger the gauge number the thinner the steel is. The thicker the steel the more the metal deck is going to cost. For instance 16 gauge is thicker than 20 gauge and 22 gauge is thinner than 18 gauge.
