What is a form deck?

Form deck serves as a permanent steel base for poured, reinforced concrete floor slabs. Unlike composite deck, it does not have embossment. Additionally, instead of being interlocked within the concrete, form deck is used to support the weight of wet concrete that is poured on top of it to create flooring systems.

What are the two materials used for deck forms?

The Different Materials You Can Use for Decking

• Wood. As stated, wood is the traditional material for decking.
• Composites. Composites are decking materials that contain both wood particles and plastic mixed together.
• Plastic Lumber.

How far can steel deck span?

Capable of open spans of up to 60 feet and beyond, composite steel joist and steel deck long-span composite floor systems provide design flexibility while introducing a range of cost and performance enhancements.

How far can pan deck 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.

What is the difference between steel form decking and composite floor deck?

Steel form decking does not increase the strength of the floor. Composite floor deck will increase the strength of the floor system. Composite floor decking has embossments in the vertical ribs of the metal decking. The embossments bond with the concrete slab.

How do you calculate concrete for a metal deck?

The concrete volume, in cubic feet per square foot, is equal to the concrete thickness above the flutes divided by 12 plus Cv. V = t / 12+Cv.

Is cedar or pressure treated wood better for decks?

When it comes to comparing treated wood vs. cedar, pressure-treated wood is the sturdier and more weather-proof of the two. It’s highly resistant to insect attack and rot, and special versions rated for “ground contact” can be buried in soil and will continue to shrug off decay for decades.

What size lumber is used for decking?

For the deck surface, you can use 2x4s, 2x6s, or 5/4x6s. The 5/4 decking (pronounced “five-quarter”), available in cedar and pressure-treated fir, is 1 inch thick and 5-1/2 inches wide with rounded edges that make for a splinter-free surface. Cedar 1x lumber usually has one rough side and one smooth side.

How thick is concrete metal deck?

Dimensionally, a concrete deck is typically thicker with a minimum thickness of 3 1/2” accounting for the roof deck and concrete thickness over the top. Steel deck can be up to 2 1/4” thick for a roof deck/Resindek® system or as little as 1/4” thick with a floor plate system.

How much weight can steel decking hold?

In short there’s no one right answer to “how much can my deck hold?” However, one rule of thumb to keep in mind while answering the question is that the answer commonly is that if a deck is properly designed, it’s built to hold 50 lbs. per square foot. It’s possible that it could hold much more weight than 50 lbs.

What is form decking?

Form deck is a workhorse in floor construction, used extensively as an economical form to support concrete slabs during erection. In some cases, form deck eliminates the need for expensive temporary deck shoring. Form deck is available in lengths from 6’-0” to 40’-0”.

What is a 1 5fd form deck?

1.5FD Form Deck Type 1.5FD form deck is used extensively in floor construction as an economical form to support concrete slabs during construction. Specifying 1.5FD deck may eliminate the need for expensive temporary shoring. Floor systems using 1.5FD deck enable the designer to space the structural members to over 10’-0” on center.

What is the maximum length of form deck?

In some cases, form deck eliminates the need for expensive temporary deck shoring. Form deck is available in lengths from 6’-0” to 40’-0”. Please check with your local New Millennium facility for lengths outside these parameters.

What are the characteristics of a steel form deck?

Designed for short spans. Designed for non-uniform loads. Designed for long spans. Designed for maximum spans. Steel Form deck is designed to serve as a permanent steel form for concrete floor slabs. Temporary wood forming is eliminated, making steel form decks fast, easy and efficient.
