What Are The Different Types Of Dovetail Roof And Floor Decking?
Dovetail deck is a long span metal decking system that’s available in both roof and floor decking. The dovetail ribs are designed so that they provide a finished looking ceiling that allows you to attach lighting, HVAC, plumbing, or electrical to the underside of the panels.
Dovetail deck will cost 2 to 3 times more than the price of a typical metal deck. If your job is under 5,000 square feet then it could actually end up costing you quite a bit more.
Dovetail Deck is only manufactured on the East Coast. If you have a job that’s on the West Coast the freight alone could cost more than $5,000. We suggest that you always contact a metal decking supplier to get an accurate cost versus guesstimating the materials cost.
Dovetail steel decking has a significantly longer lead time than regular steel decking. It will vary based upon the gauge and type of deck, but you can expect a 6 to 16 week lead time.
Unlike typical metal decking, it cannot be found in stock. Dovetail metal decking is made on an order by order basis. If you damage some of your materials or miscalculate and end up with fewer materials than you need, you will be in a tough position.
You could easily delay your job by two to four months and the price on a small job will be astronomical as just the freight alone could cost you $5,000. We recommend that you double-check all dimensions and order extra sheets at the longest required sheet lengths.
In the past, if your job required a structural metal roof deck your only choice was to use a system such as B deck. This type of system does not look finished when you look at it from the underside. B-deck has dents, weld burns, and large open spaces between the corrugations. Dovetail deck however will offer you some different solutions.
Dovetail roof deck is best used in the following applications:
Sammy X-Press Swivel Head fasteners are installed in any flat portion of the bottom flange of the decking as shown below. The connection functions similar to a drywall anchor and it has engineering that will allow you to design your mechanical load requirements.
At the time of this writing wedge nuts as discussed in the floor deck section are not intended for a roof decking application.
Dovetail floor deck is designed so that you can span long distances with shallower floor depths. This enables you to get more floors within a multi-story building.
Dovetail floor deck is best used in the following applications:
This type of metal decking system allows you a design flexibility that you don’t have with a typical metal composite floor deck. The topside of the concrete can be left exposed for a modern industrial look or you can install all of your standard flooring options such as: wood, tile, carpet, or anything else that can be installed over a concrete slab.
The critical difference is when used on a multi-story building the underside of the metal decking will function as a finished looking interior ceiling. This will save you time and money because you don’t need to build a new ceiling to cover the unfinished look that you’d have with a traditional steel floor deck.
Wedge nuts are installed in the void of the floor decking decking as shown below and are used to support whatever is hanging from them. You can also use the Sammy X-Press Swivel Head fasteners. It’s always best to let an engineer design the loads and determine which of these two systems is best.
