Steel-plastic lined (tortoise shell lining - steel, mesh, plastic integrated) is the essence of the steel-plastic composite product series. It utilizes a special rotational molding process, where steel mesh (tortoise shell) is welded to the surface of the steel body. Made from pure polyethylene (linear low-density polyethylene LLDPE, high-density polyethylene HDPE), the process combines steel plates, steel mesh (tortoise shell), and polyethylene into a single entity.

Steel-lined plastic products typically consist of the drum body, flat bottom, top cover, manhole, inlet flange, outlet flange, and liquid level hole flange. Bedroom steel-lined plastic tanks usually also include standard steel supports. These products are generally designed and manufactured according to customer requirements.

The plastic layer of the steel-lined PE storage tank boasts features such as seamless welding, no leakage, non-toxicity, resistance to aging and impact, corrosion resistance, long service life, and compliance with hygiene standards. It addresses the drawbacks of plastic rotational molding tanks, which lack rigidity, are not pressure-resistant, and have poor temperature tolerance. The interior lining of the product is flat, smooth, and robust. Compared to traditional steel-lined plastic board transport tanks, steel-lined rubber transport tanks, and steel-lined fiberglass transport tanks, it offers superior corrosion resistance, non-leakage, non-peeling, wear resistance, pressure resistance, high-temperature resistance, and a longer service life. Its price is lower than that of similar traditional storage tanks, and the product has mature technology and excellent performance, making it an ideal transport container for corrosive liquids.
