Type of Client:

Fabrication Needs:

  • Specialized steel embed plates for structural columns
  • Anchor Bolts
  • Steel Embeds
  • Gratings
  • Handrails

Unique Steel Fabrication Needs:
The client approached Madden Bolt to fabricate embed plates for sixteen steel pillars ranging from 30 to 37 feet long, weighing about 30,000 lbs, about the size of a tour bus. Client requested revisions to repair incorrect dimensions from a foreign fabricator. The client also requested a wide range of additional steel components for the construction of a massive industrial complex.

Advantages and Results:

  • On-Time/Before-Time Delivery:
    Because Madden Bolt retains in-house capabilities such as detailing and galvanizing, the customer significantly shortened procurement time. Each of the columns was fabricated and delivered to client within five days of the order. Procurement of these types of steel assemblies would have potentially taken one month or more with fabricators that do not have the same internal resources and utilize external vendors for detailing and galvanizing.
  • Accuracy:
    The experience of Madden Bolt’s detailers and welders also helps in cutting down the time to delivery. Years of knowledge in elevations, welds, structural detail codes, and welding codes per the American Welding Society, resulted in zero defects for this client.

Special Considerations:
The customer initially ordered 23-foot long plates that were theoretically unfeasible from a quality control standpoint. These dimensions could have resulted in warping due to the amount of heat used in the galvanizing process. Within hours, Madden Bolt was able to propose a range of solutions which included revised dimensions that would minimize stress to the material during fabrication and shipping.
Madden Bolt also took care of the logistics and coordination of vehicles to deliver oversized beams. Each beam required its own tractor trailer for shipping.

Unique Challenges
Atypical designs for angles, embed plates, handrails, and platforms.
Intricate platforms that required connectivity of various steel components such as stairs and ladders.
Despite the nuances in the customer’s designs, Madden Bolt was still able to deliver products to customers in weeks rather than months:
