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.

As tube mill speeds increase, tube end cut quality suffers. Meanwhile, customer requirements for end cut quality continually increase. Tube producers are turning to dedimpling and deburring machines to enhance tube cut quality and improve worker safety.

Coordinate measuring machines have progressed since their inception in the 1970s.

Fabricators should keep records carefully to avoid disallowed deductions and the ever-escalating amounts that add up until the lack of records, documentation, or supporting information is eventually discovered.

Coatings for tube and pipe can serve as a primer for subsequent painting or they can provide corrosion protection.
