PE PRODUCTS Low-density or linear low-density polyethylene (LLDPE) is a thermoplastic used in various products. It is a semi-permeable, pliable, and highly durable polymer, favored in industry for its low cost and high resistance. Polyethylene is categorized by density and chemical properties. Mechanical properties depend on molecular weight, crystal structure, and branching type. While properties vary by grade, common characteristics include good resistance to outdoor conditions and moisture, flexibility, low mechanical strength, and excellent chemical resistance. Polyethylene products are used to manufacture slides, ladders, handrails, barriers, accessories, roofing, etc. To prevent color fading, masterbatch pigments used for coloring polyethylene must have a lightfastness rating of 6 or higher. The wall thickness must be at least 6 mm (0.2 in) for sections subjected to pressure or friction, and a minimum of 4 mm (0.2 in) for barrier or shade structures that are not pressure‑exposed. Material distribution must be uniform, producing consistent thickness. Thickness and dimension tolerances are ±5 %. CARRIER CONSTRUCTION A carrier assembly will be fabricated from round‑section steel tubes meeting TS EN 10219‑2, TS‑6476, DIN 2394 standards, cold‑formed with a minimum outer diameter of 114 mm (4.5 in) and a minimum wall thickness of 2 mm (0.1 in), then welded using high‑frequency welding within standard tolerance ranges. The tubes will be sandblasted and coated with a polyester‑based electrostatic powder finish. ELECTROSTATIC POWDER COATING All metal components will be sandblasted to remove oil, dirt, and rust, creating a receptive surface for the powder coat. Fine steel shot will be sprayed with compressed air to open micro‑pores and clean the metal surface. After coating with a polyester‑based electrostatic powder, parts will be cured in a 200‑220 °C oven for 20 minutes. Following fabrication, metal parts will undergo a 10‑minute, 70 °C, 5 % oil‑removal bath, then a 15‑minute, 50 °C, 1 % iron‑phosphate bath, followed by rinsing and drying. Finally, the entire assembly will receive a uniform powder coating and be baked at 180‑200 °C for 20‑30 minutes. Welded joints will be fully coated after welding to prevent corrosion.
