Dovetail Metal Decking Guide Architectural Steel Deck Profiles Sizes and Applications

Dovetail Metal Decking Guide

Dovetail metal decking is a specialized architectural steel deck profile designed for exposed ceiling applications where appearance, structural performance, and integration with concrete systems are all important.

Unlike standard metal decking profiles such as B deck or N deck, dovetail decking features a narrow rib, fluted profile that creates a clean, linear aesthetic. It is widely used in high end commercial buildings, offices, educational facilities, and public spaces across North America.

This guide provides a complete overview of dovetail metal decking, including profile characteristics, sizes, gauges, applications, installation, and design considerations.

What Is Dovetail Metal Decking

Dovetail metal decking is a structural steel deck profile characterized by closely spaced, narrow ribs that resemble a dovetail shape. It is typically used in composite floor systems or as an exposed architectural ceiling.
