PPGI/PPGL(prepainted galvanized steel /prepainted galvalume steel )is also known as pre-coated steel,color coated steel, coil coated steel, color coated steel,pre pianted steel sheet,The PPGI steel coil/sheet made of cold-rolled steel sheet and galvanized steel sheet, subjected to surface pretreatment (degreasing, cleaning, chemical conversion treatment), coated in a continuous manner, and baked and cooled to form a product. Coated steel has light weight, beautiful appearance and good anti-corrosion performance, and can be directly processed.

The core is manufactured by batching up the resilient closed cell polyethylene or EVA foam and uniformly and continuously thermolaminating each layer together. The method ensures a bond stronger than the foam itself and eliminates the use of adhesives which can break down under long use. Useing of a polyethylene foam core ensure the buoy will not absorb water even if the skin is punctured, increasing the lifespan of the product and reducing maintenance costs. The resilient material makes the buys self fendering with a high impact absorption capacity.
The core is encapsulated with a skin of high performance polyurethane elastomer, spray applied. Polyurethane elastomer is selected for the skin because of its high resistance to abrasion, fatigue and ultra violet degradation and is significantly more durable than polyethylene materials used in the construction of rotationally moulded buoys.
Comprising through central steel tube with longitudinal gussets and external load distribution flanges at each end. A swivel assembly, certified 10 tonnes SWL, with bows at each end passes through the central tube.Â
All the material of swivel assembly are hot dip galvanized. Steelwork to be coal tar epoxy painted.
