Flexible plastic cages are made from high quality polyethylene HDPE 100 grade material, it's suitable for the dynamic load of the sea in the extreme conditions. Extensive use of strong and high-quality polyethylene material in cage brackets eliminates corrosion, minimizes expensive and difficult maintenance, and substantially increases the cage lifespan compared to steel brackets. 

Butt fusion welding is a method of joining pipes and fittings of the same width and thickness using pressure and heat. The mouth of the to be welded HDPE part is heated to 170-250 degrees in order to be smoothly smoothed. They will then be joined by touching each other. HDPE butt welding is performed by pressing down on specific areas of the heater, waiting under pressure, and combining them.
