Demonstrated effectiveness in actual rainfall! This is the ideal drainage ditch for countering guerrilla rainstorms.
The drainage gutter has a structure that is more than four times wider at the bottom than at the top of the water collection opening, making it less prone to clogging compared to traditional drainage slit structures. Continuous slits are processed at 500mm intervals at the base of the apron curb, allowing for efficient drainage of surface water. Instead of concentrated drainage through a catch basin, it features continuous drainage at two locations per meter, which is effective for overflow prevention during heavy rain. 【Features】 ○ Structure that is more than four times wider at the bottom than at the top of the water collection opening ○ Less prone to clogging ○ Continuous slits processed at 500mm intervals at the base of the apron curb ○ Efficient drainage of surface water ○ Effective for overflow prevention during heavy rain For more details, please contact us or download the catalog.
