The "No Sound Drainage Ditch" is a slotted drainage ditch with an integrated cover that combines the ditch and the cover into one unit. In traditional drainage ditches with separate covers, noise from the rattling of the cover occurs every time a vehicle passes, worsening the living environment. However, this product addresses this issue by integrating the ditch and the cover, creating a drainage system that does not produce rattling noise, thus considering the living environment. Additionally, we offer other types such as the "S type (dual slope slotted ditch)" with a 2% slope on both sides, and the "N type (flat type)" with a flat top. 【Product Lineup】 ■ S type (dual slope slotted) ■ N type (flat type) ■ F type (flat type with drainage holes) ■ G type (single slope type) ■ SG type (grating slotted) *For more details, please feel free to contact us.
