Your need
Our solution
Ease of processing
Excellent surface quality due to thin, homogenous adhesive scale layer
Laser cutting consistency
Precise control of steel chemistry delivers highly homogenous product to improve laser cutting productivityLower maintenance costsCleaner workshop to avoid brushing before sheet forming, any surface treatment (sand blasting)WeldabilityExcellent weldabilityProduct choiceWide range of size formats, grades in structural and high strength low alloy (HSLA) hot rolled steelHealth & safety Clean surface with minimum powdering during deformation means no fumes during cutting and forming operations

Advanced Surface Quality for HRS
The clean, hot-rolled surface is obtained by delivering an Oxide layer with good cohesion
and adherence by:Transforming Wustite rich (FeO) oxide layer to decomposed Wustile rich (Magnetite Fe3O4 and α–Fe) scaleControlled rolling process with precise control of coiling temperature & finishing temperatureScale composition and thickness results in enhanced cohesion to:
Avoid cracks in oxide layer and ensuring no further oxidation during transport and storage
Minimize risk of red rust formation and powdering
during material forming*

Product description
Hot rolled products with Micro Adhesive Scale
Black as hot rolled product with clean surface, low powdering. Suitable for laser-cutting
The product offers higher productivity due to higher surface cleanliness
Thickness of adhesive scale, depending on strip thickness, could be up to just half of the thickness for standard, black as hot rolled
Typical appearance
