We design heavy-duty precast concrete ducts and cable troughs for large-scale building structures. These ducts are ideal for commercial units that require a lot of networking and electrical work. Our precast concrete ducts and cable troughs are an excellent alternative to the traditional burying service lines underground as they allow for quick identification and resolution of wiring problems. Our concrete ducts and cable troughs protect your service line from environmental damage while increasing the efficiency of your power distribution system maintenance.
