What's the difference between stainless steel screws and galvanized screws? Why are galvanized screws good?

Answer:

Galvanized screws are mainly hot-dip galvanized at present.Advantages of hot galvanized screws: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;

Good reliability: the metallurgical bonding between the galvanized layer and the steel is a part of the surface of the steel, so the durability of the coating is more reliable;

The coating has a strong toughness: the galvanized layer forms a special metallurgical structure that withstands mechanical damage during delivery and use;

Time saving and labor saving: the galvanizing process is faster than other coating construction methods, and it can avoid the time required for brushing on the site after installation.In addition, the highest level of mechanical performance of galvanized screw can reach 8.8, while the stainless steel screws can only be -70, such as A2-70, A4-70, it is equivalent to 7, lower than galvanized screws.

Comprehensive protection: each part of the plating can be plated with zinc, which can be fully protected even in depressions, sharp corners and hidden places;
