The steel deck
is a cold-formed corrugated steel sheet supported by steel joists or beams. It is used to support concrete or insulating membrane of a roof. Structural metal panel roof systems are installed over a large variety of substrates. There are two general categories of substrates: one is continuous or closely spaced decking that provides solid support for the metal roof panel, the other is composed of spaced structural supports (such as purlins) where metal panels must span between supports. Most structural metal panels are used over spaced structural supports without being supported by a solid roof deck. It was developed to provide a structurally efficient product for use in roof and floor systems. Its design and fabrication maximize the properties of the steel in order to create a high strength-to-weight ratio, which lowers the material, handling, and erection costs but maintains the durability that has been proven by over 50 years of satisfactory performance.
Steel deck could be roof deck and composite floor deck as their different application using.
Roof deck products are typically used as the structural component of many flat, pitched, or arched roof systems because of their benefits with regards to strength, weight, and economy. It is commonly attached to open web steel joists, structural steel, or light gauge framing.
Composite floor deck is designed for use with structural concrete and is manufactured with mechanical embossments in the webs to create the mechanical and chemical bond between the deck and the concrete.
The composite action allows the deck to serve as the tensile reinforcement for positive bending in the slab, which significantly reduces or eliminates the need for rebar in the slab and lowers material and labor costs.
According to deck profiles characteristics, metal deck roll forming machine
for producing different types of decks are being designed and built. Including roof deck machine, composite floor deck machine, even popular Comflor deck machine, both 2 waves and 3 waves are optional. Not only deck profiles could be different, but also machine specifications could be customized, such as transmission type, gear drive or chain drive; stop cut or flying shear; plain run out table or auto stacker (Bomb type); decoiler to be manual operation or automatically; they are all being made based on real requirement.
