After more than 40 years working in the automotive sector, in SOME we have become one of the leading TIER 2 companies in the world and the leading company in metal components for safety elements such as airbags or safety belts .
But ... What does the term TIER 2 mean and how does it differ from the TIER 1 and TIER 3 industries?
The difference between TIER 1, TIER 2 and TIER 3
In the production chain of the automotive sector it is important to be able to differentiate each of the processes according to the suppliers that are part of them.
One company depends on the other and the supply chain of materials and parts is an essential part of the production process to generate an integrated model. In general, a TIER 3 company supplies a TIER 2 company and a TIER 2 company to a TIER 1 company. Thanks to all of them, it is possible to build the final product that reaches the vehicle manufacturer and, later, the end customer.
