From our perspective, there is only one high-quality product for sheet workers that combines the unique processing properties with first-class warranties.

colofer® ROBUST—More than just high resistance to scratching

This product is extremely resistant to scratching thanks to its special surface. In addition, colofer® robust is characterized by a high level of UV resistance (RUV 4) and we offer guarantees up to an altitude of 2100 m.

Steel grades of exceptional quality optimized for sheet metal workers
voestalpine operates the most modern hot-dip galvanizing lines and supplies a number of highly innovative industries, including the automotive sector. With colofer® ROBUST, you benefit from the vast experience that goes into the substrate as well as state-of-the-art coating lines. colofer® robust was specially developed for the extensive stress of outdoor applications. The specially designed, extremely resistant coating optimally protects the surface against mechanical damage. The specially designed, extremely resistant coating optimally protects the surface against mechanical damage. In contrast to other materials, colofer® ROBUST also meets the highest requirements for UV resistance (RUV 4).

Long-lasting corrosion protection 

A zinc-magnesium coating of 120 g/ m2 or a zinc coating of 275 g/ m2 ensures long-lasting corrosion protection, even in the area of cut edges.

Optimized steel grades 

In addition to our wide range of conventional grades, we offer the following two steels in colofer® robust that were specially developed for sheet workers: robust sgs 120 (soft) and robust sgh 240 (hard).

Versatile in its application

colofer®The excellent properties of robust make it especially suited to the production of standing seam roofs, trough and pipe systems, sheet worker materials and for the manufacturing of facades and sheet metal cladding of all kinds.

  • Extremely high resistance to scratching (30 N)
  • High level of UV resistance (RUV 4)

  • Highest strength

  • Guaranteed up to an altitude of 2100 meters

Made in Austria: A promise of quality  colofer® ROBUST and all other colofer® products continually undergo further development and improvement processes. All data collected form free weathering tests, lab results and reference sites are continually taken into account in the adaptation and further development of the paint coating formulas, thus ensuring continuous optimization.
 

Comprehensive guarantee services
colofer® ROBUST offers comprehensive automatic guarantees for use as a wall element, roof element or drainage system.

Highest UV resistance class thanks to RUV 4 UV stability
colofer® robust meets the requirements of RUV 4, the highest UV resistance class according to ÖNORM B3521-1 (Austrian standard). This guarantees color intensity for many years.

Best value for your money

colofer® robust offers the highest degree of scratch resistance, UV resistance and strength. These impressive characteristics are rounded off by comprehensive guarantees and a reasonable price.

  • Chloride exposure must be avoided. 
  • Avoid application in aggressive environments. 
  • Do not use silicone containing acetic acid. 
  • Ensure adequate ventilation (also at rear of claddings).
  • If colofer® robust comes into direct contact with alkaline construction materials, an oxygen and water barrier must be installed.

No fear of wind and snow

Steel is a strong material that is able to withstand heavy wind and snow loads, guarantees high resistance to failure and is characterized by excellent workability. In addition, its thermalexpansion is very low.

The following basic rules must be followedwhen using colofer® ROBUST:

  • Chloride exposure must be avoided.
  • Avoid application in aggressive environments.
  • Do not use silicone containing acetic acid when processingcolofer® ROBUST.
  • Ensure adequate ventilation (also at rear of claddings).
  • When direct contact with alkaline construction materialsoccurs, an oxygen and water barrier must be installed.
