For most fabricated structural and miscellaneous steel, hot dip galvanizing is a fairly basic process.Metis adopts this process for its anchor bolts.
Hot-dipped galvanized anchor bolts are designed for use in moist outdoor environments. The anchor bolt is dipped into the galvanized material to coat the steel with a thick material that helps prevent rust. Hot-dipped galvanized anchor bolts have more rust resistance than the standard zinc plated and the mechanically galvanized anchor bolts.
Hot-dipped galvanized anchor bolts are designed for use in solid concrete. They should never be installed into soft, hollow base materials. The hot-dipped galvanized coating is excellent for use in moist atmospheres where more rust resistance is required than the standard zinc plated anchors
can provide. The hot-dipped galvanized anchor bolts have more rust resistance than the mechanically galvanized wedge anchor bolts, but not more than stainless steel.
