Cast-in Channels

Cast-in Channels offer a fast and reliable way to create secure fixing points in concrete. Joluka’s HALFEN Cast-in Channels simplify installation and reduce construction time. Builders use them in façades, precast elements, stadium seating, tunnels, lift shafts, crane tracks, and bridge pipe supports. Each channel is rolled from high-grade steel. Options include mild steel (S235 or S275), hot-dip galvanised steel, and stainless steel (304 or 316). These materials ensure strength and corrosion resistance. T-head bolts are drop-forged, forming a solid connection between the head and shank. Joluka supplies these bolts in carbon steel with zinc plating or stainless steel for harsh environments. Anchors come pre-attached to the channel during manufacturing. They are spaced at 250mm intervals to ensure even load distribution. This setup eliminates the need for drilling or welding after concrete has set. Installation is simple. Workers fix the channels to formwork before pouring concrete. Once the formwork is removed, the exposed slot allows easy insertion of T-head bolts. This system supports quick adjustments and clean finishes. Cast-in Channels save time and money. They reduce labour, speed up construction, and offer flexible, high-strength connections. Joluka’s HALFEN system is a smart alternative to traditional fixing methods.
