Product Options

ASC Steel Deck’s steel deck products are available in a range of steel thicknesses (known as gauge). Steel thickness directly influences the structural properties of the steel deck and product price. Gauge is often selected based on the precise needs of the project or structural element. Gauge range availability varies by product, with most products offered in 16Ga – 20Ga ranges. Cellular deck offers the flexibility to order a different steel thickness for the pan material relative to the steel deck profile to which the pan is attached. Please consult the product offer key for more information.

ASC Steel Deck offers several finish options that are appropriate for a variety of applications. Our standard G60 galvanized finish is suitable for most applications, offering excellent corrosion protection and compatibility with fireproofing when used in UL fire-rated assemblies.

ASC Steel Deck offers steel deck products that are galvanized in accordance with ASTM A653. The standard galvanized coating is G60 (0.6 ounce per square foot). G90 (0.9 ounce per square foot) is recommended for high humidity and corrosive conditions. G40 (0.4 ounce per square foot) may be specified for greater economy. Heavier galvanized finishes than G90 can be specified for more severe environmental conditions and exposures. Inquire for product availability and minimum order sizes for G40 or galvanizing heavier than G90.

All ASC Steel Deck galvanized decks are manufactured from chemically treated steel coil in accordance with ASTM A653. Chemical treatment is often referred to as passivation. The chemical treatment protects the galvanized steel from developing white rust during the storage and transport of both coil and finished product. Some field-applied paint systems may not be compatible with the chemical treatment. The paint manufacturer should be consulted to determine how the deck should be prepared prior to painting. ASC Steel Deck is not responsible for the adhesion of field-applied primers and paints.

ASC Steel Deck offers the flexibility to add a white or gray primer to either the top or underside of the deck surface, including cellular deck products. This improves interim resistance to surface corrosion and improves the ease at which the deck can be painted in the field. This product option is ideal for installations where the deck is left exposed once installed as the primer finish can be post-painted to meet any interior project vision.

PrimeShield is a prime painted, cold-rolled, ASTM 1008 steel deck. The standard gray primer is applied to both the top and underside of the steel deck. This primer is suitable for use in many UL fire-rated assemblies.

ASC Steel Deck offers all standard galvanized options with factory-applied prime paint on the underside or top side of the deck. The prime paint is available in standard gray. White primer is also available. The standard 0.3 mil water-based gray acrylic primer has been specially developed to provide superior adhesion to the galvanized steel deck and is suitable for use in many UL fire-rated assemblies.

Factory-applied primer is an impermanent interim coating that is intended to have finish paint applied after the deck is installed. The galvanized with prime paint option may eliminate the need for any special surface preparation for field-applied paint applications, which is often a requirement for chemically treated bare galvanized steel deck panels.

Some materials in the roof assembly may require venting of the steel roof deck, such as roof systems with lightweight insulating concrete. Venting does not impact the structural performance of the steel deck. The deck should not be specified as vented when it is not required. The drawback of vented deck is that when concrete is poured, it can drip through the vent tabs, creating debris on the surface below. Cleaning up wet concrete or protecting the surfaces underneath with plastic sheets adds cost to the project without providing any added value to the owner when venting is not required. The requirement for venting the deck should be clearly indicated in the specifications and clearly stated in the deck schedule on the structural drawings.

For B, N, 2W, and 3W decks, upward protruding vent tabs are factory punched in the low flutes of the steel deck when venting is specified. For CP-32, venting is achieved by adding embossments to the side lap holding the lap open.

Die set ends allow for the roof deck to be easily end lapped to increase the diaphragm stiffness. The die set swages the top flange and webs of the steel deck which allows the top sheet of end lapped deck to nest tightly over the bottom sheet. When deck is not die set, the installer may have to hammer the deck to get the ends to nest together tightly to ensure good quality connections. Die Set (Swedge) ends are not standard but can be performed upon request. Die set ends are not available on all roof deck products.

Die set ends affect detailing and layout of the steel deck. Deck is spread in the direction of the male leg of the side seam. This allows the next sheet’s female side seam to drop over the male side seam. The die set is on the left side relative to the direction of spreading deck. The next adjacent run of deck will be on the left side of the deck relative to the spreading direction to nest over the dies set ends.

ASC Steel Deck roof and floor deck products are designed to be structural components for steel framed structures. As part of the normal manufacturing, handling, and transport process, it is common for the panel bundles to exhibit some degree of incidental scratching and denting. The surface defects are typically superficial and do not impact the structural capacity of the deck. On projects where the deck will be exposed to view after installation, it may be desirable to minimize the occurrence of these marks. In these cases, it is important for the designer specifying and the customer or contractor ordering the deck to request that the product be manufactured, handled, and transported for “EXPOSED” installation. This will result in modified handling and loading procedures designed to minimize (not eliminate) typical scratching and denting.
