Concrete pumping hoses skid plate disc pan is made of #20 steel and protevtive coatings. The concrete hoses skid plate use for rubber hoses support, which protect hose from damage when moving. Also the concrete hose support disc save labor working when operation.
Protective coating used in harsh corrosive environment, it can delay and weaken the corrosion of concrete hoses skid disc structure. The concrete hoses skid disc work at concrete corrosive place, the protective coating offer much help.
#20 Steel of concrete hoses skid plate have good toughness, plasticity and weldability. The tensile strength is 253-500mpa.
