PRODUCTION FACILITIES

20 Hi Sendzimir Mill

A state-of-the-art stainless steel 20 high cold rolling mill manufactured by I2S - USA can roll stainless steel coils from 2mm thickness down to the final thickness of 0.05mm, while consistently maintaining surface quality, excellent strip flatness, and thickness tolerance of maximum 3 microns.

Degreaser

The degreasing process using alkaline and hot rinsing completely removes the oil residue carried by the strip from the cold rolling mill process. 

Vertical Bright Annealing Line

The EBNER – Austria VBA line is designed with the proven muffle concept utilizing the pure hydrogen atmosphere. The result is a clean, damage-free surface, and perfect mechanical values in the annealed strips.

 

Thickness: 0.05mm - 1mm | Width: 600mm max

Speed: 50 mpm max | Temperature: 1150°C max

Skin Pass Mill

The skin pass mill improves the flatness and brightness of annealed strips.

 

Thickness: 0.1mm - 1mm

Width: 500mm max

Brightness: 500 - 600 GU

Slitting Line

A precise control of the strip width and burr level is done by meticulously setting the precision circular slitting knives and spacers of the arbor.

 

Thickness: 0.05mm min

Width: 5mm min

ID: 300 - 500mm

Cold-Rolled Stainless Steel Strip

We take the time to develop a solid understanding of your project's specific requirements, allowing us to produce a customized strip with unparalleled precision and durability.
