Depending on the requirements of the project, customers can order anchor bolts in either black or galvanized finish. The high corrosion resistance offered by the use of chromate films is attributed to the presence of hexavalent and trivalent chromium in the coating. The chromate film on the galvanized reinforcing steel is formed by the chemical reactions of hexavalent chromium with a metal surface in the presence of other components, or "activators" in acid solution.

Laboratory studies have shown other concrete design factors affect the corrosion rate of zinc. Each diameter of hot-dipped galvanized wedge anchor bolt must be installed to a minimum depth to ensure minimum holding values in the concrete. This type of anchor bolt is shaped like the letter L, so it can not be pulled out of the concrete after the concrete has hardened. Screw Bolts are ideal for fastening into Hollow Bricks. However, it may prove beneficial to provide excess chromate (100 ppm) to ensure the reactions between the galvanized rebar and concrete are limited.After the initial curing stages of the concrete, the reactions between the concrete and the galvanized steel cease. J-bolt anchoring bolts come in many different lengths, the most common are 6, 8, and 12 inches long. Tube reactions between galvanized reinforcement bars and concrete are only of concern during the initial curing stages of the concrete. The corrosion products of steel occupy a much larger volume than the metal from which they originate and the voluminous corrosion products of black steel exert a tensile stress on the surrounding concrete. Once the concrete has hardened, the only access that corrosive compounds have to the galvanized rebar is through the pores of the concrete matrix.

Galvanized steel anchors are more corrosion resistant than zinc-plated steel anchors. Accelerated exposure testing confirmed that zinc coating was able to delay considerably the onset of corrosion and that epoxy coating effectively eliminated corrosion, provided the coating was not damaged. The many considerations for choosing the proper cement screw to use for an Hexavalent chromium is partially reduced to trivalent chromium during the reaction, with a concurrent rise in pH, forming a complex mixture consisting largely of hydrated basic chromium chromate (Cr203 Cr03 x H20) and hydrous oxides of both chromium and the basis metal (zinc). During the curing process, hydrogen gas evolution occurs between the galvanized rebar and the concrete. Chromate passivation treatments are used to control reactions between the zinc and the concrete. galvanized anchor bolts concrete. The cracking of the concrete creates passageways that allow further corrosive media, such as chloride salt, to enter and cause further corrosion of the rebar.
