What's the difference between stainless steel screws and galvanized screws? Why are galvanized screws good?
5 、 comprehensive protection: every part of the plating can be plated with zinc, even in depressions, sharp corners and hidden places can be fully protected;6, save time and effort: the zinc plating process is faster than other coating construction methods, and can avoid the time after installation on the site brushing.
3. Good reliability: the combination of zinc coating and steel is metallurgical bonding and becomes a part of the steel surface. Therefore, the durability of the coating is more reliable;4, coating toughness: zinc coating forming a special metallurgical structure, this structure can bear in transit and use mechanical damage;
1, processing costs are low: hot galvanizing, rust prevention costs than other paint coating costs are low;2, durable: in the outskirts of the environment, the standard hot-dip galvanizing, rustproof thickness can be maintained for more than 50 years without repair; in urban or offshore areas, the standard hot-dip galvanized rust prevention layer can be maintained for 20 years without repair;
