Steel-lined plastic (tortoise shell lining - steel, mesh, plastic combined) is the essence of the steel-plastic composite product series. It utilizes a special rotational molding process, which involves welding a steel mesh (tortoise shell) onto the surface of the steel body, and then using pure polyethylene (linear low-density polyethylene LLDPE, high-density polyethylene HDPE) as the raw material. The steel plate, steel mesh (tortoise shell), and polyethylene are integrated into a single entity through the rotational molding process.

Steel-lined plastic products typically consist of the cylinder body, flat bottom, top cover, manhole, inlet flange, outlet flange, and liquid level opening flange. Bedroom steel-lined plastic tanks usually also feature 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, non-leakage, non-toxicity, resistance to aging and impact, corrosion resistance, long service life, and compliance with hygiene standards. It addresses the shortcomings of plastic rotational molding tanks, which lack rigidity, are not pressure-resistant, and have poor temperature resistance. The inner surface of the product is flat, smooth, and sturdy. 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 longer service life. Its price is lower than that of conventional storage tanks of the same specification. The product has mature technology and excellent performance, making it an ideal transport container for corrosive liquids.
