The two most common methods of applying zinc metal to steel handrail tubing are batch hot-dip galvanizing and inline, continuous galvanizing. The batch hot-dip method provides a coating thickness approximately 3 times that of the inline method, and a coating that lasts approximately 3 times as long. However, for indoor applications that do not require more than 500 PSI of bond strength, inline galvanized tube can be cost-effective.
