Combined Pipe Piles means pipe with a certain clutch or interlock to connect with each other, or connect with sheet piles to form a combined wall.
For the interlock, we could provide both hot-rolled SLZC9 interlocks and cold-rolled interlocks. The hot-rolled interlock could only be used to connect with hot-rolled sheet piles, while cold-rolled interlocks could only connect with cold-rolled interlocks.
Other form of interlocking system is available on buyer's request.
