Polyethylene Products Linear low‑density polyethylene (LLDPE) is a thermoplastic used in a wide range of applications. It is a semi‑permeable, flexible, and highly durable polymer that is favored in industry for its low cost and high resistance. Based on density and chemical characteristics, polyethylene is classified into several categories. Its mechanical properties depend on molecular weight, crystalline structure, and branching type. While properties vary by grade, overall it offers excellent resistance to outdoor conditions and moisture, good flexibility, low mechanical strength, and superior chemical resistance. Polyethylene components are used to manufacture slides, stairs, handrails, barriers, accessories, roofing, and more. To prevent color fading, masterbatch pigments used for coloring polyethylene must have a Lightfastness rating of 6 or higher. Wall thickness must be at least 6 mm (0.2 in) in areas exposed to pressure or friction, and at least 4 mm (0.2 in) for non‑load‑bearing barrier or shade structures. Material distribution should be uniform to achieve consistent thickness, with a dimensional tolerance of ±5 %. Carrier Construction Steel pipes with a minimum 114 mm (4.5 in) diameter and at least 2 mm (0.1 in) wall thickness will be cold‑formed and welded by high‑frequency welding in accordance with TS EN 10219‑2, TS‑6476, and DIN 2394 standards. Pipes will be coated with polyester‑based electrostatic powder paint applied in a sandblasted furnace finish. Electrostatic Powder Paint Process All metal parts will be sandblasted to remove oil, grease, and rust, creating a receptive surface for coating. A fine bead material inside a pressure‑resistant enclosure will be sprayed with compressed air to open pores for better paint adhesion and to clean the metal surface. After fabrication, metal components will receive a polyester‑based electrostatic coating and be cured in a 200‑220 °C oven for 20 minutes. Subsequently, parts will undergo a 10‑minute 70 °C dip in a 5 % oil‑removal bath, followed by a 15‑minute 50 °C dip in a 1 % iron‑pickling bath, then rinsed and dried. The final coating will be applied with durable polyester powder paint and cured in a 180‑200 °C oven for 20‑30 minutes. All welds will be fully painted after welding to prevent corrosion.
