A dovetail deck is a profiled steel decking system used to form a composite concrete floor slab. It consists of galvanized steel sheets with a distinctive dovetail-shaped rib profile. The steel deck acts as permanent formwork during concrete placement and, after the concrete cures, can work together with the concrete to carry structural loads.
The normal machinable thickness range of our steel deck roll forming machine is 0.75-1.2mm, the standard or more used in
international market is Gauge 22, 20, 18, 16 (0.75-1.5mm), working raw material is PPGI, Galvanized steel etc. We confirm machine’s configuration according to your drawing, specially the pitch and height of each wave. Sussman Machinery is always your best choice of metal deck roll forming machine.

Dovetail decking can generally be classified according to its profile geometry, rib depth, and structural application. Common configurations include:
| Type | Description | Typical Application |
|---|---|---|
| Shallow dovetail profile | Low-profile ribs with relatively small slab depth | Offices, residential floors and renovation projects |
| Standard dovetail profile | Conventional dovetail-shaped ribs designed for composite concrete slabs | Commercial and institutional buildings |
| Deep dovetail profile | Deeper ribs providing greater structural depth and potential spanning capability | Larger floor spans and heavier loading |
| Narrow-rib dovetail profile | Closely spaced, narrower ribs | Applications requiring a more uniform underside appearance |
| Wide-rib dovetail profile | Wider rib geometry with larger spacing | Floors requiring particular span or concrete-volume characteristics |
