Polyethylene Products Low‑density linear 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 categories based on density and chemical properties. Mechanical properties depend on molecular weight, crystal structure, and branching type. While properties vary by grade, the material generally offers good resistance to outdoor conditions and moisture, flexibility, low mechanical strength, and excellent chemical resistance. Polyethylene components are used in the production of slides, stairs, railings, barriers, accessories, roofs, and more. To prevent color fading, masterbatch pigments used for coloring polyethylene must have a lightfastness rating of 6 or higher. The product’s wall thickness must be at least 6 mm (0.2 in) for areas subjected to pressure and friction, and at least 4 mm (0.2 in) for barrier or shade structures that are not pressure‑exposed. The material must be evenly distributed to achieve uniform thickness. Wall‑thickness and dimension tolerances are ±5%. Carrier Construction The carrier structure consists of steel tubes with a circular cross‑section, minimum 114 mm (4.5 in) diameter and a minimum 2 mm (0.1 in) wall thickness, cold‑formed in accordance with TS EN 10219‑2, TS‑6476, and DIN 2394 standards, and welded by high‑frequency welding within the standard tolerance, size, and cross‑section ranges. These tubes are coated by sandblasting followed by a polyester‑based electrostatic powder‑coat. Electrostatic Powder‑Coat 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 blown onto the parts with pressurized air to open micro‑pores and clean the metal surface. After fabrication, the metal components are coated with a polyester‑based electrostatic powder and baked at 200‑220 °C for 20 minutes. Following powder coating, the components undergo a 10‑minute soak in a 70 °C, 5% alkaline cleaning bath, a subsequent 15‑minute dip in a 50 °C, 1% iron‑based bath, thorough rinsing, and drying. Finally, the entire assembly is painted in one continuous operation with a durable polyester‑based powder coat, cured in a 180‑200 °C oven for 20‑30 minutes. Welded joints are fully painted to prevent corrosion.
