what is a36 steel plate?
astm a36 steel plate is one of the most common grades of steel used in structural applications. this mild carbon steel grade contains chemical alloys that give it properties such as machinability, ductility, and strength that are ideal for use in constructing a variety of structures.

a36 equivalent plate grades
a36 steel is produced to meet standards set by astm, whose material standards are widely accepted in projects across the globe. however, some countries may require that structural projects which meets standards set by a different regulatory body. for example, structural projects that require plate falling under en standards may use s275 in place of a36, as it is generally considered equivalent.
