Curveline: Structural Metal Decking

• Structural Decking •

Where domed roofs and other vaulted designs are planned, decking panels curved by Curveline and installed “against the grain” save time and money vs. straight panels applied “with the grain”. Crimp-curving increases panel strength to allow use of lighter-gauge material, and achieves 15-20% longer spans for reduced framing and substructure costs. Capabilities include B or N deck in 22-18 GA.

Example of structural decking

The Neenan Company, architect and general contractor for The Vancouver Clinic (Vancouver, Washington) used 10,000 sq. ft. of curved 20 gauge “B” deck panel to support a barreled roof that accents the distinctive main entrance of the building. The structure extends back 260 ft. in length above the second floor. Click here for PDF of full article and product chart in Modern Steel Construction.

Example of structural decking

At the Virginia Air & Space Center (Hampton, Va.), metal decking is curved to conform with massive arched trusses, creating the look of a bird in flight. Metal was lower in weight and cost than concrete decking, while keeping the structure as light looking as possible. Curveline’s crimp-curving process allowed the use of lighter gauge decking, for a 20% savings in material costs.

S-shaped structural decking panel

S-curved roof decks allow architects and designers to make a bold design statement when creating entryways and lobbies, covered walkways and concourses, transit stations, parking garages and many other commercial spaces.

Example of structural decking

At this award-winning Pennsylvania Turnpike Commission maintenance facility, JSA Architecture (Pittsburgh) used curved design elements to convey the idea of motion and transportation. By using a curved metal deck and leaving the underside exposed, they were able to express the true structure of the building without covering anything up. The crimp-curving process also lent a very nice, high-tech look to the panels, according to the designer.
