Heavy plates are produced hot-rolled in unalloyed and low-alloyed steel grades. We offer heavy plates in tested quality in all common standards for many applications. In addition, we offer hotrolled slabs, which have a higher thickness than heavy plates and are used as semi-finished material for easier forming processes. 

  • Structural steel, unalloyed according to EN 10025 
  • Pressure vessel steel according to EN 10028 
  • Shipbuilding steels 
  • Steels for pipes and pipelines – EN 10208 
  • Weather-resistant plates – EN 10025 
  • Hot-rolled slabs according to EN 10025

Heavy plates are used for wind turbine masts as well as in many other construction and infrastructure projects. Depending on the application, heavy plates are used in agricultural and heavy machinery construction. A further application is shipbuilding, where heavy plates are used in the manufacturing of container ships, bulk carriers, tankers and even leisure yachts. They are also used in the construction of offshore drilling and operating platforms. In general, heavy plates are versatile, so they are commonly found in mechanical engineering. 

For applications where high pressure and high temperatures are crucial, our quality portfolio includes unalloyed boiler plates and alloyed steels for pressure vessels as well as sour gas resistant boiler plates for the tank and container construction industry. That’s why you’ll find wear-resistant steels in a variety of grades and plate thicknesses. These are also ideal for applications such as mining technology and in steel and cement plants. 

The manufacturer of heavy plates is Laminoirs des Landes S.A.S., based in Tarnos (FR).
