Continuously Hot-Dip Coated Steel Flat Products
Continuously hot-dip flat rolled products | Aluminium-zinc alloy coated (+AZ)

Continuously hot-dip flat rolled products | Aluminium-zinc alloy coated (+AZ) | For structural uses

these products are characterised by guaranteed maximum yield, tensile and elongation limits
Unlike uncoated hot rolled structural steels, this category of products does NOT require the CE marking.
For specific needs, compliance with Ministerial Decree 14/01/2008 is available, at the time of ordering, if requested.

This category is suitable for the construction of products that do not require major deformations. Steel grades with lower yield values ​​(i.e. S250GD, S280GD) are ideal for cold forming.

The tables below show only the main characteristics of the products listed and not all the technical supply conditions. For further details, please refer to the full contents of the standards mentioned on this page.
