AI Overview
Key Fabrication Processes for Large Span Bridges
- Cutting and Shaping: Use of CNC plasma and oxy fuel machines for steel plates up to 12 inches thick.
- Heavy Fabrication: Specialized shops handle girders and heavy weldments, sometimes exceeding 40,000 lbs, requiring high-capacity cranes.
- Welding and Assembly: Robotic and manual welding techniques ensure strong joints, often tested using advanced non-destructive methods, says onealmfgservices.com.
- Precision Machining: Large CNC equipment manages drilling and milling of large components to tight tolerances (e.g., 1/32 of an inch).
- Protective Coating: Specialized in-house blasting and multi-coat painting, including sophisticated paint systems for corrosion protection.
Fabrication Technologies and Capabilities
- Large-Scale Facilities: Leading firms feature over 1.6 million square feet of space with dedicated, climate-controlled environments for high-precision, large-volume fabrication.
- Accuracy: Laser tracking systems ensure real-time dimensional accuracy, often within 0.001 inches, during fabrication.
- Trial Assembly: To ensure, smooth site erection, large, complex components often undergo full, shop-floor assembly.
Industry Standards and Quality Control
- AISC Certification: Fabricators for large-span projects generally require specialized endorsements for Major Complex Bridges, Fracture Critical members, and Sophisticated Painting, note Canam-Bridges and Excel Bridge Manufacturing.
- Customization: Projects are designed to meet, specific transportation, load-bearing, and environmental conditions.
Prominent companies in this sector include High Steel Structures LLC, Canam-Bridges, Industrial Steel Construction, and Excel Bridge Manufacturing.
