We recently completed a large trench drain project at DFW Airport Hardstand with Austin Bridge and Road. The project utilized our 10" wide fire retardant trench drains with extreme duty frame and aircraft rated grating. The project was shipped in 16' trench drain sections. Austin Bridge and Road seemed to effortlessly install the 3300 linear foot project. We believe it had something to do with our user friendly Dura Trench drain system!
