Surface Treatment
☆ Black
Black is a common method for metal heat treatment. The principle is to make an oxide film on the metal surface to isolate the air and achieve rust prevention. Blackening is a common method for metal heat treatment. The principle is to make an oxide film on the metal surface to isolate the air and achieve rust prevention.
☆ Zinc
Electro-galvanizing is a traditional metal coating treatment technology that provides basic corrosion resistance to metal surfaces. The main advantages are good solderability and suitable contact resistance. Due to its good lubrication properties, cadmium plating is commonly used in aviation, aerospace, marine, and radio and electronic products. The plating layer protects the steel substrate from both mechanical and chemical protection, so its corrosion resistance is much better than zinc plating.
☆ Hdg
The main advantages are good solderability and suitable contact resistance. Due to its good lubrication properties, cadmium plating is commonly used in aviation, aerospace, marine, and radio and electronic products. The plating layer protects the steel substrate from both mechanical and chemical protection, so its corrosion resistance is much better than zinc plating. Hot-dip zinc has good corrosion resistance, sacrificial protection for steel substrates, high weather resistance, and resistance to salt water erosion. It is suitable for chemical plants, refineries and coastal and offshore operating platforms.
Frequently Asked Questions
What manufacturing standards do your carriage bolts and nuts follow?
Our carriage bolts and nuts are manufactured in strict accordance with DIN603 and ASME B18.5 standards to ensure global compatibility and high quality.
What materials and grades are available for these fasteners?
We primarily use premium stainless steel for carriage bolts and nuts. The available grades include Grade 8 and 8M, which provide excellent strength and corrosion resistance.
What surface treatments do you offer for rust prevention?
We offer three main surface treatments: Black (oxide film), Zinc (electro-galvanizing), and HDG (Hot-Dip Galvanizing). Each option is designed to meet different environmental and corrosion resistance requirements.
What is the typical lead time for delivery?
Our standard delivery time is normally between 30 to 40 days, depending on the volume of the order and specific customization requirements.
Can the packaging be customized to our specific needs?
Yes, our standard packaging consists of cartons and pallets, but we are fully capable of customizing the packaging based on your specific requirements.
