Three powers of surface treatment

Ability to make proposal

Support from the development stage

It is our specialty to support manufacturers from the product development stage. We offer a wide range of optimum proposals that combine thermal treatment, surface treatment, and spread processing to prevent product problems in the design stage. These unique proposals are the most welcomed by our customers. Please feel free to contact us.

Ability to solve problems

Contact us for any difficulties.

You may experience problems, such as failure to obtain the product specification expected in the design stage while the cause is unknown. The more complex the factors, the more difficult it is to find the cause. In such a case, please contact us. We can help you with a wide range of solutions, including thermal treatment, surface treatment, and spread processing.

For long-term outdoor use

For many years of use in outdoor exposure conditions, it is necessary to prevent contact corrosion between different metals with aluminum frames. We therefore proposed the design that withstands further aging degradation by plating the foundation for high corrosion resistance of the original GEOMET®.
