Air-wiping
The Air-wipe material handling system was developed by South Atlantic in 1982 as a means to hot dip galvanize long bar shapes in a manner that results in a smooth uniform coating over the entire length of the bar, but without the drips or rough edges often associated with hot dip galvanizing. Material processed using the Air-wipe equipment has the same zinc alloy coating as all other material galvanized by South Atlantic, eliminating the uneven coating weights associated with First-in-last-out dip processes, and the added benefit of post-galvanizing air knives to remove any drips or roughness.
South Atlantic uses the Air-wipe equipment to galvanize angles, flats, rounds and light beams marketed by our Steel Products division, and to produce ASTM A767 Class 2 galvanized rebar for fabrication after galvanizing which is marketed by our Reinforcing Products division. The Air-Wipe equipment is not available for use on customer-owned material.
