Different producers have different profiles and different interlock systems. All of the available sections, however, can be broken into two types based on end use.

The most common end use requires sections which resist bending moment. This requirement for beam strength, or section modulus, is provided by "Z-profiles" and "U-profiles". The second end use is for sections which require interlock strength. This need for interlock strength is created when sheeting is installed as a circular cell and backfilled with granular material. The confined fill pushes outward and thereby creates hoop tension in the cell wall. The "flat sheet piling" sections transmit the hoop tension through their interlocks.
