Airport Passenger Boarding Bridge Components for the Transportation Industry

Airport Passenger Boarding Bridge Components
Airport Passenger Boarding Bridge Components

At Signal Metal Industries, Inc., we possess the resources and experience to supply production components to the complex needs of the transportation industry. Using our state-of-the-art machining and fabrication capabilities, we are able to accommodate large production runs in-house with accelerated delivery schedules. We've also implemented a state-of-the-art supply chain application that can process sub-assemblies within our MRP system. It allows us to create a stocking program that is ideally suited for extremely tight delivery deadlines. This allows us to react to our customer's changing needs and quickly ramp up operations to meet any supplier requirement.

This transportation customer in Texas asked us to manufacture a number of column weldments for airport passenger boarding bridges. Each unit weighed 6,000 lbs. and required varied part dimensions up to 16' long and 6' in diameter with tolerances as tight as + 0.001". Using A36 and A572-50 plate, we performed flame cutting, plasma cutting, welding, CNC machining, CNC drilling, press brake forming, plate rolling, and thermal stress reliving. Combining robotic automation with innovative programming procedures, we were able to reduce project costs by applying standard sub-assemblies to various final part configurations. Once completed, our NACE certified finishing department used a high-quality paint to provide additional surface protection for an enhanced overall appearance on each bridge component. In order to ensure quality control across all phases of production, every part underwent extensive NDT, dimensional verification, and coating analysis.

The project entailed many of our core competencies and required that our team perform together seamlessly so that we could meet the customer's tight production schedule. Impressed by our work and commitment to quality, they continue to depend on us for manufacturing services by ordering 8-10 units per month. All of our work was performed in full compliance with standards by ASME, ASTM, AWS, and NACE.
