STI Group's service portfolio is systematically expanded with the help of the company's Research & Development Department in order to continually improve the cost-effectiveness and environmental compatibility of products. Upon customer request, the Department will investigate faults or develop new surface solutions.  With the help of the Chemical Laboratory, the Metallography Department, the Development Laboratory and the galvanizing test facility, it is possible to develop processes for top quality requirements. Regular chemical analysis and efficient bath management ensure that this quality is consistently maintained and the coating results are reproducible while also minimizing the use of resources.
