Welcome to Leakproof Steel

Our specialty is sturdy equipments with lowest electrical operation cost, standard bought outs considering easy availability. Our design requires minimum spares inventory.

We undertake turnkey projects, as well as design & consultation for flat steel processing lines. We have our trained expert team for inspection, erection, supervision & commissioning of mechanical, electrical, hydraulic systems.

Electrolytic Clealing Line

During the galvanizing entry section or high temperature annealing, the oil or grease on the surface of the strip will affect the galvanized surface quality and conglutination of the strip. Degreasing & rinsing line is applied for removing oil, residual iron and other contamination on the strip, so as to control the value of the residual carbon and iron surface quality and cleanliness can be guaranteed, especially for the strip for automobile and household electric appliance. We can provide the following degrease line.

Electro-degreasing & Rinsing Line

When the strip runs through alkali liquid tank, and the strip is set as anode or cathode through DC with reversal polarity, then gas is created on surface of the strip, which emulsifies the oil film and separate the oil from the strip surface It is provide by productivity practice that the processing of electrolytic degrease is better than alkali degrease in many sides, such as degreasing efficiency and quality.
