Composite floor Metal decking for floors

Composite floor steel Deck sheets have proved one of the most effective methods of constructing floors in steel building over the years to be a simpler, faster, lighter and very economical construction in high rise RCC / steel-framed building systems. The system is well accepted by the construction industries for different types of floor systems. The construction industry has been looking beyond the conventional method for wide commercial and industrial applications and exploring for the better to win over today’s changing environmental challenges and for green building and less carbon footprint construction.

In addition to acting as a form deck (shuttering) during the construction phase, composite metal deck sheets substitute the tensile reinforcement in the concrete slab.

Metal-Concrete Composite deck

The steel composite deck as the name indicates is a part of the floor structure with a ribbed profile that binds with a concrete slab poured on top of it and mutually forms a composite floor structure. This interlocking between dissimilar materials like the concrete and the floor deck is produced through a system of embossment rolled into webs and flutes of the deck and ribs which are built into the deck, creating a reinforced concrete slab that serves the dual purpose of permanent form and positive reinforcement a substitute the tensile reinforcement in the concrete slab. The deck initially acts as a form for the concrete and after the concrete cures, it acts as the positive moment support.

How Shear Connectors interlocks the two dissimilar material?

This is made possible by the composite action developed between two dissimilar materials like concrete and steel by the provision of shear connectors at the interface of the two materials. These shear connectors are embossments in the deck sheets in a typical pattern unique to each profile. These embossments develop friction as well as a mechanical interlock between the concrete and steel sheet. These two reactions take care of longitudinal shear developed at the interface of the concrete and steel sheet, preventing slip and thereby enabling the two materials to act as a single entity of composite deck. To ensure friction at the embossments, there should not be any paint or grease on the sheet surface in contact with concrete nor should any vibrating load be permitted to act on the slab until the concrete has set completely and composite action has developed. The friction between th steel sheet and concrete is expressed by a co-efficient denoted as "k" while the mechanical interlocking between steel and concrete made effective by the embossments is denoted by "m". The design of the composite slab is completely governed by shear-bond values of a composite deck sheet denoted by two coefficients "m" and "k".

Metal decking is used in wide commercial and industrial applications. Metal decking typically has a corrugated or trapezoidal profile, achieved through a process called roll forming. Metal decking is installed by using screws or pneumatically driven pins and can also be welded.

Composite Floor Metal Profile Sheets

Most Profiled sheeting manufacturer use strip no thicker than 2 mm and primarily designed to use with concrete to form composite floor slabs. There are two broad classes - shallow profiles, up to about 175 mm deep, which is used for short span applications, and 'deep decking', typically 225 mm deep, for longer spans. Shallow profiles are usually either of 'trapezoidal' or 're-entrant' profile. Deep decking is a trapezoidal profile, with sections and embossments that are intended to improve the structural performance.

Structural metal panel roof systems are generally installed over a two categories of substrates: one is continuous or closely spaced decking that provides solid support for the metal roof panel, and the other is composed of spaced structural supports (such as purlins) where the metal panels must span between supports and it is the most commonly used substrates for structural metal panels over spaced structural supports (purlins) without the supported of solid roof deck.

Deep Profile Sheets

The deep profile roof deck is a wide rib structural metal roof deck that provides a support surface for various types of roofing materials has exceptional strength and specified when a strong solid base is required to support a heavy load. Generally, deep profile roof decks are specified for buildings that have a green roof, or an air conditioning system. Deep profile roof deck is a popular choice for the construction of large-scale buildings, and where architectural aesthetics is very important because it eliminates the need for purlins. Structural Metal Roof Deck is moulded in deep profile depths of between 85mm and 200mm. Popular profile depths include 100mm/ 106mm/ 135mm/ 153mm/ 158mm/ 200mm. Deep profile roof deck sheets are available in gauges of between 0.7mm and 1.25mm.

Types of Metal Decking Sheets

Steel roof and floor decking, aluminum floor decking, and acoustical metal decking are the different types of metal decking.

Steel decking sheets

Steel decking is used as flooring, can provide additional stability to a structural frame. When used as roof decking, a narrower rib pattern must be created to increase strength and support roofing materials. Steel decking is an economical, permanent, easy-to-install option for builders. As a cold-rolled steel product, it offers high quality with little maintenance. Steel decking exposed to the elements will typically be galvanized to prevent rusting. The large variety of steel gauges and coatings available means that steel decking can easily comply with code requirements.

Acoustical metal decking

Acoustical metal decking is made from steel that has been rolled and formed into ribs. The depressions are then filled with acoustical batting, which provides varying degrees of sound insulation. Acoustical decking is tested and given a Noise Reduction Coefficient rating (NRC). The NRC is the measure of the amount of noise energy absorbed by the surface of the decking and is averaged over commonly occurring frequencies. The rating can be used by the consumer to make certain the material chosen will provide the desired level of sound absorption. This type of decking is ideal for use in large facilities where sound control is an issue, and because it can be curved, it is often used in the construction of domed sports arenas.

Aluminum decking

Advances in aluminum alloying techniques allow aluminum decking to be more widely used than in the past. The use of aluminum can keep construction costs down and allow for a wider variation in the look and feel of decking. However, unlike steel decking, which acts as its support, aluminum decking requires additional support structures.

Cellular Composite Deck

Cellular Composite Floor Deck is a traditional Composite Floor Deck with continuous flat sheet steel welded to the underside beaded liner panel allows for increased deck spans with increased clear spans and increased cantilever spans over non-cellular types. Available with acoustical cellular deck option, fiberglass insulation batts installed in the deck cells at the factory under controlled conditions.

Advantages of Composite Metals Deck Sheets: ‐

  • Lightweight: It reduces the weight of the concrete floor by almost 50 % which reduces the concrete thickness and reinforcement.

  • Faster Construction: Profile shapes provide additional space for nesting service lines within the notches for faster installation than conventional shuttering which gives immediate access to a working platform of permanent form and positive reinforcement, saves time and helps to rapid installation. It gives a congestion-free area during construction.

  • Economical: A more economical steel section is used in composite construction than conventional non-composite construction for the same span and loading. The concrete and steel are utilized effectively.

  • Fire & Corrosion Resistant: Encased steel beam has a higher resistance to fire and corrosion. Deck profile sheet is offered in zinc coated and pre-coated steel, zinc ranging from 120 to 275 gsm which is resistance against corrosion.
