It is semi‑permeable, pliable, and highly durable, offering low cost and excellent resistance, which makes it popular in industry. Polyethylene grades are classified according to density and chemical properties. Mechanical properties depend on molecular weight, crystal structure, and branching type. Although characteristics vary by grade, the material generally provides good resistance to outdoor conditions and moisture, flexibility, modest mechanical strength, and superior chemical resistance. Polyethylene is used to manufacture slides, stairs, railings, barriers, accessories, roofs, etc. To prevent colour fading, masterbatch pigments used for colouring must have a light fastness rating of 6 or higher. The minimum wall thickness is 6 mm (0.2 in) for parts subjected to pressure or friction and 4 mm (0.2 in) for non‑load‑bearing barriers and shade structures. Material distribution must be uniform, and dimensional tolerance is ±5 %. Carrier Construction Steel tubes with a minimum 114 mm (4.5 in) diameter and at least 2 mm (0.1 in) wall thickness are cold‑formed to TS EN 10219‑2, TS‑6476, DIN 2394 standards and welded by high‑frequency welding. Tubes are electrostatically powder‑coated with a polyester‑based paint. Electrostatic Powder Coating All metal parts are blast‑cleaned to remove oil, dirt, and rust, creating a porous surface for better paint adhesion. Fine steel shot is sprayed with compressed air to open pores. After blasting, parts are coated with polyester‑based electrostatic powder and cured at 200‑220 °C for 20 minutes. After manufacturing, metal components undergo a 10‑minute, 70 °C, 5 % solvent‑degreasing bath, followed by a 15‑minute, 50 °C, 1 % iron‑phosphate dip. They are then rinsed, dried, and finally powder‑coated in an outdoor‑grade polyester system and cured at 180‑200 °C for 20‑30 minutes. Weld seams are fully coated to prevent corrosion.
