Polyethylene Products Low- or medium-density linear polyethylene (LLDPE – Linear Low Density Polyethylene) is a thermoplastic used in a variety of products. It is a semi‑permeable, soft‑moldable, and highly durable polymer that is favored in industry because of its low cost and high resistance. Based on density and chemical characteristics, polyethylene is classified into several categories. 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 to manufacture slides, stairs, railings, barriers, accessories, roofs, etc. To prevent color fading, masterbatch pigments used for coloring polyethylene must have a lightfastness test value of 6 or higher. Wall thickness must be at least 6 mm (0.2 in) at points subjected to pressure and friction; for products that are not pressure‑exposed, such as barriers and shading elements, a minimum of 4 mm (0.2 in) is required. The material must be evenly distributed to achieve uniform thickness. Wall‑thickness and dimensional tolerance are ±5 %. Carrier Construction The carrier construction consists of steel tubes with a circular cross‑section, formed by cold drawing in accordance with TS EN 10219‑2, TS‑6476, DIN 2394 standards. Tubes have a minimum outer diameter of 114 mm (4.5 in) and a minimum wall thickness of 2 mm (0.1 in), are welded by high‑frequency welding, and are produced within the standard tolerance, size, and section ranges. These tubes are then sandblasted and coated with a polyester‑based electrostatic powder paint. Electrostatic Powder Paint All metal parts are first sandblasted to remove oil, dirt, and rust, creating a porous surface for better paint adhesion. Fine metal beads are sprayed with pressurized air to open pores and clean the metal surface. After fabrication, the metal components are coated with polyester‑based electrostatic paint and baked in a 200‑220 °C oven for 20 minutes. Subsequently, the parts undergo a 10‑minute dip in a 70 °C, 5 % concentration oil‑removal bath, followed by a 15‑minute dip in a 50 °C, 1 % concentration iron bath. After rinsing and drying, the components are coated with durable polyester‑based powder paint and cured in a 180‑200 °C oven for 20‑30 minutes. All welds are painted in one continuous coat to prevent corrosion.
