What Is a Dovetail Deck?

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.

Types of Dovetail Profiles

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

Application

Dovetail composite floor decks are commonly used in:

  • Commercial and office buildings – floor slabs between steel or concrete structural frames.
  • Residential and apartment buildings – lightweight floor construction and multi-story structures.
  • Schools, hospitals, and institutional buildings – efficient floor systems where rapid construction is required.
  • Industrial and warehouse buildings – mezzanine floors and elevated platforms.
  • Parking structures – composite floor construction where the system is suitable for the required loads and exposure conditions.
  • Renovation and infill projects – particularly where lightweight permanent formwork is advantageous.
