The present invention discloses a continuous, shallow bath plastic pickling tank for carbon or stainless steel strip or product. The present invention provides first and second end stands spaced from each other and secured to a foundation with a trough extending between the end stands anchored at the center and adapted to receive a pickling acid therein. An expandable seal according to the present invention couples each end stand with the trough with the seal specifically allowing for the thermal expansion of the trough relative to the stands while prohibiting the escape of pickling acid or fumes. The invention includes a device to allow for cleaning of the seal with cleaning fluid such as flushing water.
