The architectural uses of steel are vast; it can be used with a structural purpose, purely for aesthetics, or a little of both. From the exposed frame of a building and unique bracing expressions, to smaller features such as staircases and balustrades, exposed beams and columns, and canopies and balconies, architectural steelwork takes a number of almost limitless forms.

Steel is a popular material for architectural structures because of its cost effectiveness and sustainability. It has great machinability during manufacturing, including the ability to create curved members for increased architectural expression, and the capacity for off site fabrication, which reduces construction time and labour costs. Steel is more durable than other metals, with its longevity extended by finishing coats. In the same vein, it has good fire and corrosion resistance, which too can be increased by specific finishes. Steel has a great strength-to-weight ratio, making it suitable within load bearing applications.

Architecturally exposed structural steel is steel which is purposely visible. Unlike most forms of structural steel, which provides the framework for buildings and is so hidden by insulation and cladding, exposed steel can be seen. This may take the form of architectural steelwork, or may serve a more functional purpose, but either way it should be aesthetically pleasing to those who view it.
