Mieres Tubos (Grupo Condesa) and ArcelorMittal Flat Carbon Europe have worked together on the design and creation of safety barriers combining new material - high strength low alloy steel and the metallic coating Magnelis®.
The co-engineering partnership, which dates back to May 2011, is celebrating its latest success with MieresTubos – which manufactures the safety barriers - securing a prestigious safety certification. The company acquired the CE marking - which shows that the product meets strict EU health, safety or environmental standards - for two of its products from Bureau Veritas, based on certificates showing consistency of performance.
The two products are: N2W4 (commercial name: BMSRA4/C-MT) certified as BMSRA4/C-MT(MG) which is made of high strength low allow steel and Magnelis® (ZM310).
Other safety barriers systems using the metallic coating Magnelis® have been -or are- in the process of being certified by MieresTubos:
The use of high strength, low alloy steels combined with the metallic coating Magnelis® is bringing safer, sustainable, and cost effective safety barriers.
The qualities of high strength, low alloy steels include:
Increased corrosion protection with Magnelis®, even on cut edges
The superior performance of Magnelis®, the steel metallic coating made with zinc, 3.5% aluminium and 3% magnesium, protects safety barriers against corrosion while maintaining mechanical properties.
The coating has been tested in salt spray and outdoor tests (see images below). Tests also show the behaviour in soil and concrete is superior compared with traditional heavy zinc coating.
Magnelis®, which uses less zinc than pure zinc coatings thereby considerably reducing zinc runoff in the soils, comes with a 20-year guarantee for safety barriers.
