Polyethylene Products Low-density or linear low-density polyethylene (LLDPE – Linear Low Density Polyethylene) is a thermoplastic used in various products. It is a semi-permeable, pliable, and highly durable polymer that is favored in industry for its low cost and high resistance. Polyethylene is classified into categories based on density and chemical properties. Mechanical properties depend on molecular weight, crystalline structure, and branching type. Although properties vary by type, general characteristics include good resistance to outdoor conditions and moisture, flexibility, low mechanical strength, and excellent chemical resistance. Polyethylene products are used to manufacture slides, stairs, railings, barriers, accessories, roofs, etc. To prevent discoloration, masterbatch pigments used for coloring polyethylene must have a lightfastness rating of 6 or higher. The material’s minimum wall thickness is 6 mm (0.2 in) for parts exposed to pressure and friction, and a minimum of 4 mm (0.2 in) for barriers and shading components that are not subject to pressure. Material distribution must be uniform to achieve consistent thickness. Wall thickness and dimensional tolerances are ±5 %. Carrier Construction A carrier construction will be fabricated from cold‑formed steel tubes with a minimum 114 mm (4.5 in) diameter and at least 2 mm (0.1 in) wall thickness, conforming to TS EN 10219‑2, TS‑6476, and DIN 2394 standards. The tubes will be welded with high‑frequency welding and produced within the standard tolerance, dimension, and cross‑section ranges. The carrier will be painted by sandblasting the tubes and applying a polyester‑based electrostatic powder coating. Electrostatic Powder Coating All metal components will be prepared by sandblasting to remove oil, dirt, and rust, creating pores for better paint adhesion. Fine steel shot will be propelled with compressed air to open pores and clean the metal surface. After fabrication, metal parts will be coated with a polyester‑based electrostatic paint and cured in a 200–220 °C oven for 20 minutes. Following coating, metal parts will undergo a 10‑minute dip in a 70 °C, 5 % concentration degreasing bath, then a 15‑minute dip in a 50 °C, 1 % iron bath. After rinsing and drying, the components will receive a final polyester electrostatic powder coat and be baked at 180–200 °C for 20–30 minutes. Weld seams will be completely covered with a solid coat to prevent corrosion.
