ArcelorMittal Europe – Flat Products High strength steels for structural profiles New grades go beyond the standard

High performing cold-formed profiles with high strength steels Cold-formed steel profiles are important components in many steel buildings. Commonly used as secondary structures, these profiles are utilised between primary portal frames to support roofing and cladding elements. Secondary structural profiles distribute wind or snow loads from the building envelope to the main frame and foundations. Cold-formed profiles include purlins, rails, sleeves, rafters, cleats, bracings, and other related accessories. ArcelorMittal has developed lighter, thinner, stronger, and more durable steels, enabling...

Two ranges of high strength steels for specific needs • According to the EN10346 standard, steels for construction are supplied with minimum guaranteed values for the yield and tensile strength (properties measured in rolling direction). ArcelorMittal offers two different ranges of metalliccoated high strength steels: construction grades and high strength low alloy (HSLA) grades. The selection of the appropriate range depends on the required processing or in-use properties. • High strength low alloy (HSLA) grades offer a controlled range of mechanical properties and better formability (properties...

In-use properties Cold forming High strength metallic-coated steels show excellent cold forming ability. • Framing, structural profiles (purlins, rails, sleeves, rafters, cleats, bracing, and all related accessories) They are specifically designed for bending, profiling, punching, and light drawing operations. • Long span decking • Composite floors Higher material springback can be expected with higher YS, but can usually be compensated by tooling adjustments. Metallic coated steels can be deformed easily, low bending radii should be avoided. • Under structure rails for facades • Roofing and...
