Elevating OEM Standards:
Why TOSTEM is the Strategic Partner for Your Global Projects.
In the parts manufacturing industry (OEM), the key is not just about getting the production "done," but about achieving "perfection" according to the set specifications.
As a leader in aluminum products, TOSTEM does not just offer parts manufacturing; we offer "Japanese Quality" as the core heart that makes our products internationally recognized—especially in the B2B sector where high precision is required.

JIS (Japanese Industrial Standards) is an industrial standard from Japan that is among the most stringent in the world. For doors-windows and aluminum profiles, the standards that TOSTEM uses are:
JIS H4100: Aluminum and Aluminum alloy extruded shape
JIS H8602: Combined coating of anodic oxidation and organic coating on aluminum and aluminum alloy.
Adopting JIS standards is more than just a mark of quality; it represents a 'Standard of Safety and Value-Driven Investment' for long-term construction projects.
