In-house inspection standard of Yao Kanaami
- Standards built in the products
- Yao kanaami's in-house inspection standards are three times stricter than JIS standards in terms of the permissible number of major defects.
■In-house inspection standards surpassing JIS standards
We apply our own in-house inspection standards, which are stricter than the JIS standards, to the production of our products. Only those products that pass both our in-house standards and the JIS standards are delivered as Yao Kanaami products.
This standard reflects our firm commitment to quality.

Tolerance for transverse mesh of Dutch-woven wire mesh
Yao kanaami's Dutch-woven wire mesh products consist of wire mesh manufactured to meet very strict tolerance so as to eliminate variability in filtering flow rate across the products.
