remark: | |||||||
1 rubber and metal bonded items apply only to the edge of waterstop which include steel. | |||||||
2 demand and supply can discuss about the question if there is other special needs, such as mold assessment test, but the anti-mildew properties should be equal or higher than two grade. | |||||||
