Application of steel floor decking in steel frame houses

At present, prefabricated steel frame houses are popular all over the world because of their fast construction speed, low cost, energy saving and environmental protection, and more and more developers use prefabricated steel structure houses to build apartments. And steel floor decking is also widely used in prefabricated steel structure houses.

So how does steel floor decking apply in prefabricated steel frame houses?

The role of steel floor decking

In prefabricated steel structure houses, the role of steel floor decking is the same as that of other steel structure buildings. It is nothing more than a form deck, and of course it can also be used as a composite floor. It is nothing more than the fact that the spacing between frame beams or joists in prefabricated steel structure houses is relatively small, so the force on steel floor decking is even smaller. The depth of the steel floor decking is required to be smaller.

The types of steel floor decking

The type of steel floor decking should choose a steel deck with a smaller depth. In Solideck, we recommend SD38-914, SD35-750 or SD46-600. These three types of steel decks have one thing in common: the rib height is relatively shallow . Since the span of frame beams or joists is relatively small, this determines that the rib height of the steel deck can be lower. In addition, considering the self-weight of the floor and the reasons for the subsequent floor treatment, the lower the rib height, the more generous the space left.

The material of steel floor decking

In prefabricated steel structure houses, the steel floor decking is generally made of high-strength galvanized steel sheets, the strength is generally not less than 345Mpa, and the double-sided galvanizing amount is 275g/m². The high strength can ensure the composite steel decking. Zinc is more durable than steel decks.

The connection of steel floor decking

Steel floor decking is connected in one of three ways: welding, screws or bolts. In general steel structure buildings, welding is mostly used. In prefabricated steel structure houses, since the cross-sectional size of frame beams or joists is very small, the welding method may cause penetration of the steel plate of the beam body; in addition, prefabricated steel structure houses are more likely to use non-open fire operations , During the welding process, it will inevitably cause fire, so Solideck recommends to use screw connection.

As steel floor decking is more and more widely used in prefabricated steel structure houses, there are more practices and applications that we need to try. Currently, in the design of steel frame houses in Canada and the United States, Solideck’s SD38-914 and SD46-600 steel decks have been selected, and Solideck has used its skilled professional skills to get customers to adopt the suggestions.As a professional factory engaged in the steel floor decking industry for nearly 20 years, Solideck is willing to make more efforts and explorations.
