Bull Bar Production
ARB’s manufacturing processes have been adapted and refined over the years to ensure we can produce the best accessories available. Click on the links below for details on how a bull bar goes from a flat piece of steel to a quality protection accessory.
Product Options
Laser Cutting
Every bull bar starts off as a flat piece of steel sheet. The components are cut into shape using ARB's in-house laser cutters, which produce superfine cuts of 0.2mm without any heat distortion. This process results in 100% accuracy, which is maintained throughout the fabrication of the bar.
Folding
The flat pieces of steel are then folded to make up the sections of the bull bar on a Computer Numerically Controlled (CNC) machine which ensures maximum accuracy and consistency. Most of our bull bars utilise ARB's five fold design, which provides increased strength with each fold.
Robot Welding
Subsequent to being folded into shape, each section is welded utilising a robot welder. Robot welders are used for straight-forward, repetitive welding jobs that require speed and accuracy.
Robot Grinding
A robot grinder then grinds the welded sections down so they are level and visually appealing. ARB's unique grinder is torque and pressure sensitive, and incorporates both a grinding belt and a finishing belt so the end product is guaranteed to be smooth.
Tube Work
ARB's bull bars are made with strong 2.6mm wall thickness tubing. The tube is cut to the desired length and bent with a CNC Eagle internal mandrel bender, ensuring consistency and even wall thickness across all sections.
Assembly
When individual components are complete, the bull bar is assembled. All sections – pan, wing, uprights, outer frame and chassis brackets are placed in a jig and tack welded. This is followed by finish welding for strength and aesthetics.
Post Assembly
To finish off the manufacturing process our bars are steel shot blasted, bathed in a phosphate solution, then powder coated and oven baked to ensure a rich and durable finish. This doubles as an excellent base for painting if colour coding is required.
