Refined Hot-Dip Galvanized Nuts
Hot dip galvanized nuts have the following advantages
1. Good durability: In suburban environments, the standard hot-dip galvanized anti rust thickness can be maintained for more than 50 years without the need for repair; In urban or coastal areas, the standard hot-dip galvanized rust prevention layer can be maintained for 20 years without the need for repair.
2. Low processing cost: The cost of hot-dip galvanizing for rust prevention is lower than that of other paint coatings.
3. Good reliability: The galvanized layer is metallurgical bonded with the steel and becomes a part of the steel surface, so the stability of the coating is relatively reliable.
4. Time and effort saving: The galvanizing process is faster than other coating construction methods and can avoid the time required for painting on the construction site after installation.
5. Strong coating toughness: able to withstand mechanical damage during transportation and use.
6. Integrated protection: Every part of the plated part can be coated with zinc, providing comprehensive protection even in recesses, sharp corners, and hidden areas.
Its performance level is usually between 4.8 and 10.9, with a variety of specifications, such as M12-M48. The thickness of hot-dip galvanized coating is generally ≥ 54 μ m. The quality and standards are usually produced according to the requirements of GB5780-2000 and GB41-2000, and the mechanical properties comply with GB3980.1-2000 and GB3980.2-2000.
