Corrosion protection for distribution box fixing bolts
Barrier Protection: Barrier protection acts by isolating the metal from humidity and other contaminants. Sacrificial coating: In this method, a less noble metal or alloy is used for protection. Zinc coating provides corrosion resistance by acting as a barrier and. idgework, and the practical aspect the full coating system, applied after installation. (For WRS steel structures the bolts, nuts and washers should be of WRS material and are not given any protec-tive treatment, unle ion until the rest of the coat-ing system is applied. (For a major structure. WHY WE NEED TO CONSIDER CORROSION? It is essential to know about corrosion and its effects in order to avoid mistakes. However, the ultimate choice of the materials used, and the corrosion. The bolts or fasteners holding the assembly together are often the areas where corrosion starts first, and where the effects of corrosion may have the most serious consequences. Corrosion categories are tabulated in BS EN ISO 9223, ranging from C1 (very low corrosivity) to C5 (very high corrosivity).
