Steel Structures
Structural steelwork contractor · Belfast
Since 2000, main contractors have trusted Steel Structures to manufacture and install structural steelwork to specification, on budget and on programme.
About us
Established in November 2000, Steel Structures designs and fabricates structural steelwork for projects ranging from traditional portal frame and beam-and-column buildings to complex curved and geometrically challenging roof structures. Our experience also extends to internal structural alterations, including cut-and-carve works, and extensions to existing steel frames.
Based at our Dunmurry works, we combine in-house detailing and manufacturing expertise with the capability to deliver complete steelwork projects, from design through to installation. Whether supporting a main contractor on a large-scale project or supplying a single beam for a local builder, we bring the same practical experience, attention to detail and commitment to quality.



Services
From estimating and pre-construction consultation through to design coordination, in-house Tekla detailing, fabrication, CE marking and installation, Steel Structures delivers tailored structural steelwork services to meet the individual requirements of each project. We work with main contractors and local builders alike, providing practical expertise and a flexible approach across projects of varying sizes and complexity.
