Structural Welding Quote

Structural Welding Quote Example — $6K Steel Staircase

A four-person structural shop in central Ohio needed a complete bid for an interior steel staircase in a two-story office renovation. The GC spec called for 14 treads, a mid-landing, pipe handrail with OSHA-compliant picket spacing, and diamond-plate treads on A36 steel. The shop estimated 16 hours of fabrication and 4 hours of field installation for roughly 1,200 lbs of steel. IronKit generated the full bid with itemized line items, scope notes, and exclusions in under 12 minutes. The GC signed off the same day — the shop owner said it would have taken him an entire evening to put together the same package by hand.
