Edge Form and Accessories

ASC Steel Deck offers a range of accessories to complement our steel deck offering. Our accessory offer includes flashings, weld washers, profile-specific neoprene foam, and galvanized steel closures.

Edge Form

Edge form and flashings are an important part of the composite deck-slab system and contain the concrete during the pour. Edge form contains wet concrete and establishes one point of depth control during the pour. ASC Steel Deck offers a range of Cee, Zee, Angle, Channel, and Hat trim designs that meet edge form, cell closure, filler plate, column flashing, and other customer installation requirements.

Galvanized steel flashings are custom-manufactured by ASC Steel Deck to meet project requirements. The flashings are formed from ASTM A653 galvanized steel sheets. Flashings are available in a range of gauges with standard lengths of 10 feet.  Shorter lengths are available upon request. Please note the minimum width of any stiffener or flat cross-section width is ¾”. Channel, Hat, and Cee webs must be ¾ of an inch wider than the flange width.

Weld and Anchor Washers

Weld washers prevent the creation of holes in light-gauge deck when welding 24- and 26-gauge material. Anchor washers improve the diaphragm shear values of form deck profiles. ASC Steel Deck offers the following configurations:

  • C1.4-32 Weld Washer – 14-gauge x 3⁄8″ diameter hole for welded attachment.
  • C0.9-32 Weld Washer – Variable Gauge x 3⁄8″ diameter hole for welded attachment.
  • CP-32 Anchor Washer – 16 gauge x 7/16” diameter hole for welded attachment of CP-32 where higher diaphragm shear values are required.

Weld washers are for use with 26 and 24-gauge C1.4-32 and C0.9-32 only. Weld washers are not designed for 22-gauge or heavier steel decks.

Neoprene Closures

Neoprene closures are used on the top and bottom of the steel deck to reduce vapor, moisture, and air from infiltrating into the building roof or floor assembly. These are die-cut from black closed-cell neoprene foam. The foam is manufactured in accordance with ASTM D-1056 and passes the FM-VSS No. 302, UL 94HBF, and UL 94 HF1 flammability tests.

Profile Cut Metal Closures

Metal closures control animal nesting within the building structure. These closures are commonly for partially enclosed projects such as parking garages and stadiums. Metal closures can be used in combination with neoprene closures or with caulking to reduce noise infiltration as part of an acoustically engineered system. Metal closures are stamped from a minimum of 22-gauge galvanized sheet steel.

Customer Note: When accessories are requested in project specifications, the accessory location must be clearly shown on the structural and architectural drawings.
