One of our customers is a big manufacturing company for military aircraft production, repairment and maintenance. Before 2008, they made their own casters because all other casters that were made by domestic factories could not meet their requirement, which is at least 3 tons in loading capacity, easy to move, strong in impact resistance, good in abrasion resistance, and non-flammable. In 2008, Colson made a recommendation to them with its Albion 610 series Trionix wheel and PF polyurethane wheel. Their strict testing proved that Colson casters completely met their requirement, and therefore Colson honorably became their official supplier.
