Concrete Pontoon Specification:

 1. Concrete: Pontoon precast units are manufactured by experienced personal. We adopt high quality premium C50 Concrete, containing silicon particles and fibers. Silicon particles can improve the strength and waterproof performance, and fibers can increase anti-crack on concrete surface and improve the flexural strength. Pontoon surface will go through brush treatment evenly to achieve antiskid effect. 
 2. Rebar: Rebar is used to provent the corrosion caused by halide ion erosion and  subsequently the phenomenon of blowout of concrete.                                                                                                                     
 3. Polystyrene Board: The board is filled with 15kg/m3 polystyrene foam internally and moisture content is below 3%.  
 4. Water and electricity reserved pipeline: Water and electricity reserved pipeline is arranged in the middle of pontoon with cover plate for convenient installation and maintenance.
 5. Fender: Three layer of natural antiseptic hardwood are installed on both sides of pontoon by hot dip galvanized wire rod and further protected by anti-collision rubber fender.
