Polyethylene Products Linear low‑density polyethylene (LLDPE) is a thermoplastic used in a variety of applications. It is a semi‑permeable, flexible, and highly durable polymer that is favored in industry for its low cost and high resistance. Polyethylene is classified into different categories based on density and chemical properties. Its mechanical characteristics depend on molecular weight, crystal structure, and branching type. While properties vary by grade, common attributes include good resistance to outdoor conditions and moisture, flexibility, low mechanical strength, and excellent chemical resistance. Polyethylene is used to manufacture slides, stairs, railings, barriers, accessories, roofs, and more. To prevent color fading, masterbatch dyes used for coloring polyethylene must have a lightfastness rating of 6 or higher. The material thickness must be a minimum of 6 mm (0.2 in) for areas subject to pressure and friction, and a minimum of 4 mm (0.2 in) for barrier and shading components that are not subjected to load. Thickness must be uniform across the product, with a dimensional tolerance of ±5 %. Carrier Construction The carrier framework consists of steel tubes with a minimum 114 mm (4.5 in) diameter and a minimum 2 mm (0.1 in) wall thickness, formed by cold shaping in accordance with TS EN 10219‑2, TS‑6476, DIN 2394 standards, and welded using high‑frequency welding. The tubes are sandblasted and coated with polyester‑based electrostatic powder paint. Electrostatic Powder Paint Process All metal parts are first sandblasted to remove oil, dirt, and rust, creating a porous surface for better paint adhesion. Fine steel shot is then sprayed with compressed air to roughen the surface and eliminate contaminants. After manufacturing, the metal components are coated with polyester‑based electrostatic paint and cured in a 200‑220 °C oven for 20 minutes. Following coating, the parts undergo a 10‑minute dip in a 70 °C, 5 % concentration oil removal bath, then a 15‑minute dip in a 50 °C, 1 % concentration iron bath. After rinsing and drying, the components receive a final electrostatic powder coating and are cured in a 180‑200 °C oven for 20‑30 minutes. All welds are fully painted to prevent corrosion.
