HALLOWELL Storage Locker is constructed of super strong galvanneal steel—carbon steel coated with zinc on both sides by a continuous hot dip process. Galvanneal is harder than regular galvanized coating and more scratch- and damage-resistant. 13- to 14-gauge steel frame/sides; 16-gauge steel shelves. All-welded assembly. Expanded metal sides and back; diamond perforated door. Single-point lock. Made in USA.
