Dimensions for heavy plate and strip products - Ruukki

• Heavy plate products
Heavy plates are delivered hot-rolled, normalised rolled, and normalised in furnace, in thicknesses ranging from
4.7 to 150 mm. The thickness range for thermomechanically rolled steels is usually between 8 and 60 mm. The
available thickness range, especially the maximum thickness of a product, is limited by mechanical properties
and product approval requirements of the steel used. Therefore, the available thickness ranges for individual
steels must always be checked from our website.
Heavy plates
• The maximum weight of a single plate is approximately 12 tonnes.
• The maximum width is 3,300 mm.
• Depending on the thickness, the minimum width is either 1,901 mm or 2,000 mm.
• Deliveries in widths other than 1,000 to 1,900 mm and 1,000 to 1,999 mm must be agreed upon separately.
• Typical length is 2 to 15 m.
• The absolute minimum size for (cut) heavy plates is 1000 mm x 2000 mm, and must be agreed upon separately.
• An order position (position) is a lot consisting of plates with identical dimensions and in the same steel grade.
• At its smallest, a position can consist of a single plate with a minimum weight of 2,000 to 5,000 kg, depending
on its thickness.
• Generally, the combined length of individual plates in a single position should be at least 4,200 mm.
• In the case of thermomechanical steels thicker than 40 mm, the combined length must be at least 5.5 m.
Hot rolled, normalised rolled and normalised heavy plates
The highest yield strength class for these steel grades is R e ≤ 420 MPa. Table 3 displays the general dimensions
for heavy plates. The minimum and maximum dimensions for individual steel grades are absolute, even when
they fall within the general dimensions provided below.

1) Products over 15 metres and up to 22 metres long are available to order. However, the maximum weight for a single plate (approx. 12 tonnes)
must not be exceeded.
2) The maximum width is determined by thickness and length. The absolute maximum width is 2,150 mm.
Thermomechanically rolled heavy plates
The highest yield strength class for thermomechanically rolled steels is Re ≤ 500 MPa. Table 4 displays the general
dimensions for heavy plates. The minimum and maximum dimensions for individual steel grades are absolute,
even when they fall within the general dimensions provided below.

1) Thermomechanical steels R e ≤ 355 MPa and R m ≤ 450 MPa are delivered in thicknesses less than 8 mm, as shown in Table 3.
2) Plates over 15 metres and up to 22 metres long are available to order. However, the maximum weight for a single plate (approx. 12 tonnes)
must not be exceeded.
