A coil well is a trough-shaped recess running along a truck or trailer's loading floor that holds heavy steel coils securely in place during transport.
Steel coils are round and can weigh several tonnes, which makes them hard to secure with straps or wedges alone. Lowering a coil into the well stops it rolling or sliding sideways, so the load stays stable and safe.
When not carrying coils, the well can be covered with planks or boards so the trailer works like a normal flatbed or curtain-sider. This makes coil-well semi-trailers versatile for steel and general freight.
