Product Description

 Product details 

 Ball flat steel is a kind of medium profile mainly used in shipbuilding and bridge fabrication, in which the marine ball flat steel is used as auxiliary medium profile for shipbuilding. In recent years, with the rapid development of shipbuilding industry, the demand for marine ball flat steel is booming. Generally large vessels and regular ships in the design of the main hull mostly use the ship's ball flat steel, using the same thickness and material of the same thickness and material of the connected sheet steel as the bone material (also known as the bone or keel).

Standard of execution
At present, the domestic ball flat steel production mainly carries out the GB/T9945-2012 "hot rolled ball flat steel" standard, and a few enterprises in the European standard EN10067:1996 "hot rolled ball flat steel size, shape, weight and allowable deviation", similar to other standards also include JIS G3192, ISO 657-19.

Size
The size of the ball flat steel is generally divided according to the nominal width, the minimum specification is 8# (that is, the nominal width is 80mm), and the maximum specification is 43# (the maximum nominal width is 430mm). Each specification has 2~5 different thickness.
