ASO Products Make the World Go Round

Chrome-plated Steel Bars and Hydraulic Components

No matter how extreme the conditions get – arctic cold, the searing heat of the desert or the corrosive effect of constant exposure to seawater – our chrome-plated products ensure machinery, cranes and vehicles can deliver the required performance at all times. We not only produce steel bars in the dimensions you require and with the desired chromium alloy in the thickness you need but we also offer many further processing options such as milling, drilling, threading or grinding. Our further processing capabilities even include manufacturing ready-to-install hydraulic components where we are classed as one of the leading companies. Our hydraulic components withstand high pressures and immense mechanical loads. They come with a long service life with low wear and are optimally tailored to suit your given application. You benefit from superior reliability and the associated security for your product solutions.
