Material Specifications Steel

Steel.
Our Columns and brackets are produced from S235, S275
and or S355 High strength steels, these grades of steel
conform with the following standards:

EN10149 – Hot rolled flat products of high yield strength
steels for cold forming.

EN10210 – Hot finished structural hollow sections of non-
alloy and fine grain structural steels.

EN10219 – Cold formed structural hollow section of non-
alloy fine grain steels.

EN10025 – Hot rolled products of non-alloy structural
steels – Technical delivery conditions (includes amendment
A1:1993)

Galvanising.
In order to obtain the best quality galvanising for our products, all steel used is closely monitored for silicon content and it’s
suitability for the galvanising processes. The galvanising process and testing fully complies with BS EN ISO 1461:1999.

Hot rolled flat products in High-Strength Steel obtained Hot rolled products are made of type S235 Construction
by cold shaping: Steel :
This new Steel is obtained by the addition of microalloy Alloy composed mainly of Iron with Carbon to which different
elements (Titanium, Niobium, Vanadium…), which increases elements (Manganese, Silicon, etc.) are added in order to
its resistance and makes it easier to weld, whilst maintaining obtain minimal mechanical resistance.
good cold deformation. It also has better corrosion resistance.
