Classification of High Strength Galvanized Bolts

High strength galvanized bolts can be divided into high-strength hot-dip galvanized bolt and high-strength cold-dip galvanized bolt according to different production processes. Generally, hot-dip galvanized bolts are used a little more, because the cold-dip will drop after a long time. Surface treatment of high strength galvanized bolts is generally based on customer requirements, the commonly [...]
