Steel Grades

Steel grades

It is known that in every country there are different kinds of steel grades. To make this as clear as possible for you, Intra BV has gathered these steel grades. We have made a distinguish on sheet piles steel grades, tubular pipes steel grades and horizontal tie rods steel grades. Compare steel grades per region and if you have any questions, please don’t hesitate to contact us.
