Material Specifications Aluminium

Aluminium.
Our poles are produced from 6060T5 Aluminium alloy, the
brackets and other tubular elements from 6060T6 alloy, the
backing plates from 5038H111, the resistance elements
from AlSi7Mg or AlSi10Mg cast Aluminium and decorative
parts in AlSi13 cast Aluminium.

These Aluminium alloys comply with NF EN 755 series
standards for conical posts, brackets and other tubular parts
as well as backing plates, and standard NF EN 1706 for
parts in cast Aluminium.

Bars, tubes and spun profiles - 6060T5 or T6:
The mechanical characteristics are obtained by tempering and rendering. Valmont’s specific rendering treatment makes it
possible to obtain above-standard mechanical characteristics.

The 6060 alloy is a good compromise between mechanical strength and corrosion; it is particularly apt for anodising and cold
deforming. Good welding results are obtained with classic procedures under inert gas (TIG or MIG).

Piece of cast Aluminium AlSi7Mg and AlSi10Mg:
There are two main casting processes used - sand or shell - according to the geometrical complexity of the product, the
degree of precision needed for the dimensions and the quantities to be produced.

According to the level of resistance required, the pieces can be heat treated.
