# Often asked: How To Install Metal Decking For Concrete?

## How is metal decking installed?

Large sheets of metal are pulled off of rolls and led through rolling dies that create the ribbed profile. Metal decking is used for flooring and roofing and also for the creation of forms for concrete. Metal decking is installed by using screws or pneumatically driven pins and can also be welded.

## How far can steel decking span?

Based on a standard profile of about 2 in. to 3 in. composite deck, typical spans are 10 ft to 15 ft. “When you use a dove- tail profile, you can span 15 ft., but you have to shore it,” notes Abbata. The situ- ation then becomes one of give-and-take.

## What gauge is metal decking?

Metal decking is most commonly 16, 18, 20, and 22 Gauge in thickness.

## What is a pan deck?

Pan decking is a corrugated sheet metal designed to have structural concrete poured over top it. Nowadays, it’s a generic term for metal floor decking.

## How do I calculate how much concrete I need for a deck slab?

How to calculate concrete:

1. Determine how thick you want the concrete.
2. Measure the length and width that you’d like to cover.
3. Multiply the length by the width to determine square footage.
4. Convert the thickness from inches to feet.
5. Multiply the thickness in feet by the square footage to determine cubic feet.

## What is a floor deck?

Composite or non-composite metal decking for floor construction.

## Why is metal decking corrugated?

The Benefits of Corrugated Floor Decking Corrugated metal is a lightweight building material that provides remarkable rigidity given its slim profile. That strength makes it an ideal addition to concrete floors in need of extra reinforcement.

## What is metal deck flooring?

Metal floor decking is a corrugated metal panel that’s used in a floor application. It’s installed over steel joists or steel beams and supports the wet concrete. There are embossments in the vertical ribs of the decking that bond with the concrete slab.

## What thickness is 10 gauge sheet metal?

15 U.S. Code § 206. Standard gauge for sheet and plate iron and steel

Number of gauge Approximate thickness in fractions of an inch Weight per square foot in pounds avoirdupois
10 9/64 5.625
11 1/8 5
12 7/64 4.375
13 3/32 3.75

## What is a composite concrete deck?

Composite slabs consist of profiled steel decking with an in-situ reinforced concrete topping. The decking not only acts as permanent formwork to the concrete, but also provides sufficient shear bond with the concrete so that, when the concrete has gained strength, the two materials act together compositely.
