General - All Deck Products Composite Floor Deck Roof Deck Cellular Deck Form Deck This web site edition has been slightly modified and edited for the electronic format.
Figure 3 page 21 has been revised from the original to illustrate proper rigging for hoisting deck onto the structural frame. Revisions adopted August SDI NOTICE The Steel Deck Institute makes no representation or warranty respecting any information contained in this manual, including but not limited to the accuracy, completeness, or suitability of such information for any particular purpose or use.
The Steel Deck Institute expressly disclaims any and all warranties, express or implied.

In addition, neither the Steel Deck Institute nor any of its Members or Associate Members shall be liable for any claim, demand, injury, loss, expense, cost or liability of any kind whatso- ever which in any way arises out of or is connected with the use of the information contained in this publication, whether or not such claim, demand, loss, expense, or liability results directly or indirectly from any action or omission of the Steel Deck Institute or any of its Members or Associate Members.
Any party using the information contained in this manual assumes all liability arising from such use. This manual is intended to be an aide and general guide for the safe and proper erection of steel deck. The objectives are safety, which is always paramount, and providing a good quality job. This manual is not intended to define specific duties or responsibilities of any of the participants involved in doing the work nor is it intended to replace necessary contract documents.
Each participant-the designer, the deck manufacturer, the general contractor, the deck erector, the owner, and each individual worker-should be aware of their individual responsibilities, as defined in the contract documents, so that the job environment will be as safe as possible and also to produce a good job. While the information presented in this manual has been prepared in accordance with generally recognized engineering principles and accepted construction practice, it is recommended that it be reviewed by the design professional and the builder for its applicability for any specific job.
It also greatly benefited from the generous contributions of time, skill and knowledge of many other organizations and individuals. Cheryl Janusz for editing the text; Mr. Merle Nordyke for his excellent cartoons; Mr. Although not all suggestions for changes were implemented in the text, we were able to accommodate most of them and to compromise on others. As is the case with other SDI publications, a continuing effort will be made to keep the document up to date and to issue revisions as warranted by changes in construction practice.
General-All Deck Products Steel deck is made by cold forming structural grade sheet steel into a repeating pattern of parallel ribs. The strength and stiffness of the panels are a result of the shape of the ribs and the material properties of the steel. Deck lengths can be varied to suit job conditions but, because of shipping considerations, are usually less than 40'.
Standard deck width varies with the product used but full sheets are usually 12, 18, 24, 30 or Deck is typically furnished in a standard width with the ends square cut. Any cutting for width, such as at openings or for angular fit, is done at the job site. Deck is typically attached to the building frame with arc puddle welds, self drilling screws or powder or pneumatically driven pins.
Sheet to sheet fastening is done with screws, button punching crimping , or welds. Composite Floor Deck After installation and adequate fastening, floor deck serves several purposes. It a acts as a working platform b stabilizes the frame c serves as concrete form for the slab and d reinforces the slab to carry the design loads applied during the life of the building.
Composite decks are distinguished by the presence of shear connector devices as part of the deck. These devices are designed to mechanically lock the concrete and deck together so that the concrete and the deck work together to carry subsequent floor loads. The shear connector devices can be rolled-in embossments, lugs, holes or wires welded to the panels.
The deck profile configuration can also be used to interlock concrete and steel. This bare top surface can be expected to develop rust before concrete is placed. The bottom side of the deck has a primer coat of paint. See the next section on Roof Deck for a description of primer paint.
Galvanized deck has a zinc coating on both sides. Composite floor deck is normally installed so the panel ends do not overlap on the supporting beams.
Shear lugs or profile shape often prevent a tight metal-to-metal fit if panel ends overlap. The air gap caused by overlapping prevents proper fusion with the structural steel when sheet end laps are shear stud welded.
Adequate end bearing of the deck must be obtained as shown on the erection drawings. If bearing is actually less than shown, further investigation is required. Roof Deck Roof deck is not designed to act compositely with other materials. Roof deck acts alone in transferring horizontal and vertical loads into the building frame. Roof deck rib openings are usually narrower than floor deck rib openings. This provides adequate support of rigid thermal insulation board.
Roof deck is typically installed to endlap approximately 2 over supports. However, it can be butted or lapped more than 2 to solve field fit problems. Since designers frequently use the installed deck system as part of the horizontal bracing system the deck as a diaphragm , any fastening substitution or change should be approved by the designer. Continuous perimeter support of the deck is necessary to limit edge de- flection in the finished roof and may be required for diaphragm shear transfer.
Standard roof deck finishes are galvanized or primer painted. The standard factory applied paint for roof deck is a primer paint and is not intended to weather for extended time periods. Field painting, touch up of abrasions and deterioration of the primer coat or other protective finishes are the responsibility of the buyer.
It is recommended, however, that any field paint be applied over a small test area of the primed deck and tested for compatibility and adhesion prior to proceeding with field painting. Special paint, or paint to be applied over galvanizing, is available on special order but must be adequately described to the manufacturer before bidding.
Cellular Deck Cellular deck is made by attaching a bottom steel sheet to a roof deck or composite floor deck panel. Cellular deck can be used in the same manner as floor deck. Electrical, telephone and computer wires are easily run through the chase created between the deck panel and the bottom sheet.
When used as a part of the electrical distribution system, the cellular deck must be installed so that the ribs line up and create a smooth cell transition at abutting ends. The joint that occurs at butting cell ends must be taped or otherwise protected to prevent concrete from entering the cell. Cell interiors must be free of welding burrs or other sharp intrusions to prevent damage to wires. When used as roof deck, the bottom flat plate is usually left exposed to view.
Care must be maintained during erection to keep good alignment and prevent damage. Installation of deck for this purpose requires special methods for attachment to the frame because the flat plate-now on the top-can prevent direct access to the deck material that is bearing on the structural steel. It may be advisable to treat the flat top surface to prevent slipping. Cellular deck is always furnished galvanized or painted over galvanized. Form Deck Form deck can be any floor or roof deck product used as a concrete form.
Connections to the frame are by the same methods used to attach floor and roof deck. Welding washers are recommended when welding metal thickness is less than 0.
