    PIONEER V-LOCK® tank wall profile


    The modern and unique PIONEER V-LOCK® wall profile provides the strength of corrugated steel and maintains perfect support for the liner molded to the inside of the tank wall.

    The PIONEER V-LOCK® design maximizes the strength of your tank to ensure it stays in shape when full or empty while minimizing liner stress.


    The PIONEER V-LOCK® Tank Profile design is unique to Pioneer Water Tanks’ manufacturing. Along with high-grade industrial materials, the corrugated profile makes Pioneer Water Tanks stiffer and stronger than rounded corrugated tanks.

    The PIONEER V-LOCK® tank design is listed in technical specifications for every model of Pioneer Water Tank, “TANK BODY Wall Panels – Grade 300MPa (44,000psi) steel sheets, profiled and fabricated according to the V-LOCK wall panel design, are fastened horizontally to each other and vertically to column supports. Nominal sheet dimensions are 2.2m (7.2ft) x 1.1m (3.6ft). Wall panel sheets are pre-curved for each tank size to achieve the required circumference.”

    Vertical Wall Panel Connections

    Wall panel sheets are joined vertically using hot-dipped galvanized steel
    bolts to a C-section column which supports the structural actions arising from seismic design loads. A metal cover is used to protect the bolted connection from tampering and to provide an aesthetic finish that matches the finish of the tank body material.

    The above image was taken inside of a commercial Pioneer Water Tank, with an Industratex® liner being affixed to the PIONEER V-LOCK® tank profile with multiple points. This alleviates stress on the liner.


    The Pioneer wall profile supports the liner better and makes it last longer. The shape of the PIONEER V-LOCK® tank design prevents wicking, unlike with a rounded corrugation.
