Upper Couplers

Are you currently looking to update/upgrade or diversify your current supply chain for upper coupler assemblies?  

Are you currently looking to update/upgrade or diversify your current supply chain for upper coupler assemblies?  GMI is well-equipped to handle your requirements, from the raw material to a painted finish.  We understand many of the current upper coupler plates are galvanized in the marketplace.  This is something we currently do not provide internally, however, we do offer and provide both powder coating and e-coating to these assemblies.

We current provide a single source solution to the transportation industry for these assemblies.  Currently, each customer has specific requirements for the welding of these components.  The goal of GMI is to provide another option for customers with specific requirements.

Specific requirements can be provided upon request.  For example, if you require a pre-heat of the king pin prior to welding, GMI can accommodate your needs.  GMI can also provide any pin requested based on current supply chain.

GMI uses robotic welders for consistent welds and sustainable throughput.  Most all dimensions are available with our current robotic cell configuration.  Minor adjustments may be required to existing GMI-owned fixtures to accommodate any rail pattern requested.
