How Cannon Bars are Made


All cannon bars are made from formulated, cold rolled and annealed steel. "The Best bar - Bar none!" needs the best steel to make it last.

From the raw steel, each bar is precisely laser cut. Once cut, bars are heat-treated and quenched, creating just the right hardness for strength and flexibility.

The hardened bars are then carefully straightened and surface-ground to the ideal thickness - ensuring strength and a certain amount of flexion.

Surface-ground bars are then high-precision CNC-milled. Differing milling patterns are used, depending on the style of tip that the bar is fitted with.

After milling, bars are put into the hands our skilled tradesmen who give it Cannon's claim to fame, the PRECISION GROUND GROOVE: Every bar has a true and centered groove that is accurate to within .002" of the desired gauge. It is this care and attention that really makes our bars stand out against the competition.

The next step uses a flame-tempering process to harden the bar rails 5 points more than the tie-straps on most models and brands of chain.

A majority of bar lengths are also pressed at the heel in order to reduce vibration and prevent premature cracking from vibration.

Bars of certain lengths are then put through a stress-relieving system in order to expel tension that has built up in the bars in the production processes. This step ensures that the bars will not be internally stressed and prone to premature cracking.

Finally, the bars are ready for the finishing touches. Cannon applies the attractive new brushed gunmetal finish to most of the bars. Some longer lengths and specialty bars still have Cannon's classic matte black painted finish. The bars are then stamped with our identifying numbers, and screened with our logo. They are now ready to be tipped, packaged and shipped to the customer.
