UQAB uses high quality steel, especially formulated and heat treated. Every heat treated lot is sampled and destructively tested for material strength and link elongation – assuring compliance to designed criteria. All Chain is then proof tested, 100%, every link. The UQAB Chain is continuously hot dip galvanised to provide the deep strong protective coating you have come to expect which has over 30% more zinc per unit volume than mechanical coating. In the hot dip process, the galvanised zinc coating is alloyed with the base steel creating a metallurgical bond that is several orders of magnitude stronger than mechanical bonding.
