Product Details

Steel plates for ships refer to hot-rolled steel sheets for hull structure produced by classification societies.The general strength structural steel of China Classification Society standard is divided into four quality grades: A, B, C and D (CCSA, CCSB, CCSC, CCSD), and the high strength structural steel of China Classification Society standard is three strength grade and four quality grade.


In order to make hull steel plate stronger,surface treatment is the most important step during ship building.Without good surface treatment,ships steel plate will be bad upon worse weather coming.For this step.ship yards usually use steel shot,type of S330,S390.Some time,they use steel grit to mixed for blasting,like GP25,GP40 or GL25,GL40 etc.Currently some shipyards use stainless steel grit which be made with special steel materials,it has longer fatigue life and long blasting,fatigue life is higher 30% than normal alloy steel grit.
