It is a semi‑permeable, softening, highly durable polymer that is favored in industry for its low cost and high resistance. Based on density and chemical properties, polyethylene is classified into several categories. Its mechanical properties depend on molecular weight, crystal structure, and branching type. While specific properties vary, it generally offers good resistance to outdoor conditions and moisture, flexibility, low mechanical strength, and excellent chemical resistance. Polyethylene is used to manufacture slides, ladders, guardrails, barriers, accessories, roofs, and more. To prevent color fading, masterbatch pigments used for coloring polyethylene must have a lightfastness value of 6 or higher. The material thickness should be at least 6 mm (0.2 in) for components exposed to pressure or friction, and at least 4 mm (0.2 in) for non‑load‑bearing barriers and shade structures. Material distribution must be uniform to achieve consistent thickness. Product thicknesses and dimensional tolerances are ±5%. Electrostatic Powder Coating Process All metal components are sandblasted to remove oil, dirt, and rust, creating a porous surface for better paint adhesion. Fine steel beads are then propelled with compressed air to further open pores and eliminate contaminants. After manufacturing, metal parts are coated with a polyester‑based electrostatic powder and cured in a 200‑220 °C oven for 20 minutes. Subsequently, the parts undergo a 10‑minute dip in a 70 °C, 5 % concentration oil removal bath, followed by a 15‑minute immersion in a 50 °C, 1 % concentration iron bath. After rinsing and drying, the components receive a final polyester‑based powder coating applied outdoors, then cured in a 180‑200 °C oven for 20‑30 minutes. All welds are fully painted after welding to prevent corrosion.
