Structural steel
Beams, columns, connections, and project-specific assemblies fabricated to drawings and specs.
Boulder Steel Fabrication
Steel fabrication for Boulder commercial builders.
FSW fabricates structural and miscellaneous steel in its Denver shop and delivers to commercial projects across Boulder and Boulder County.
What we fabricate
Steel scope for commercial schedules.
Boulder's mix of institutional, tech, and mixed-use commercial work calls for tight detailing and schedule discipline — handled in-shop before steel ever reaches the site.
Embeds and base plates
Anchor assemblies, base plates, and embeds coordinated to the foundation and framing schedule.
Miscellaneous metals
Stairs, rails, ladders, bollards, frames, and supports that finish out commercial scope.
Shop-to-site coordination
In-house estimating and detailing keep the bid, scope, and fabrication connected through delivery.

Why Boulder builders work with FSW

Commercial steel goes sideways when scope is vague or the shop and field never talk. FSW keeps the work tied to drawings, specs, and schedule so project teams get clear answers instead of surprises.
