Sustainable
Structural steel is an incredibly sturdy and flexible construction material, which makes it an attractive choice for both residential and commercial applications - but that’s not all it has going for it.

Versatile
Structural steel is both physically and aesthetically versatile - it can be bent, shaped, and fashioned in just about any way you want, and that means it can be manipulated for both pragmatic and aesthetic reasons.

Durable
The elements aren’t a worry for structural steel; it’s unaffected by cold, wind, and rain, and its critical temperature for fire susceptibility is relatively high. So unlike wood or concrete, structural steel is a ‘set it and forget it’ construction material.
Our structural steel fabrication services
Steel frames
We can fabricate entire structural steel frames for warehouses, factories, bridges, and just about any other commercial or industrial application you can think of. Our skilled team members can fabricate your steel frame entirely to spec, and will do so quickly and efficiently.
Steel beams
If you don’t require an entire steel frame, and are just in need of one or several individual steel beams, we’ve got good news - we can fabricate those too! Just let us know how many steel beams you need and the specs to which they need to be fabricated, and we’ll handle the rest.
Structural steel modifications and alterations
We don’t just create new structural steel fabrications - we can modify existing ones in line with our clients’ evolving needs and business models. Whether you need to expand your existing structural steel fabrication, or a complete rework and overhaul of the structure, be rest assured that we can handle it.
