Hot rolled steel sheet

In the hot rolling process, the cast ingot is heated to red-hot in an oven (furnace) (heat transfer pit), where it is raised to a temperature between 900ºC and 1200ºC. It is heated in order to provide ductility and malleability in order to make the reduction of its surface area easier.

Hot rolled products, steels for structures (UNE EN 10025-2: 2006), are supplied in the following formats:

Length (mm) Width (mm) Thicknesses (mm)
2000 1000 3 – 4 – 5 – 6 – 8 – 10
2500 1250 8 – 10
3000 1500 3 – 4 – 5 – 6 – 8 – 10 – 12
6000 1500 3 – 4 – 5 – 6 – 8 – 10
4000 2000 3 – 4 – 5 – 6 – 8 – 10
6000 2000 3 – 4 – 5 – 6 – 8 – 10 – 12

Classes for suitability for coating by hot galvanising based on the analysis of the casting (recommendations):

Classes % elements by weight
Yes Yes + 2,5% P P
Class 1 ≤ 0,030 ≤ 0,090
Class 2 ≤ 0,35
Class 3 0,14 ≤ Yes < 0,25 ≤ 0,035

Class 2 applies only to special Zinc alloys.

Note: When agreeing on the requirements of hot-dip galvanising, account must be taken of the shape of the products and the composition of the zinc bath, other treatment parameters and other factors.
