Product Hot-Dip Galvanizing Process
1. Pre-treatment Process
After the steel parts enter the production line, they undergo alkaline degreasing, acid pickling (hydrochloric acid concentration controlled at 15–20%), cleaning and neutralization, and fluxing treatment. This process removes surface oil and oxide layers, ensuring the steel surface remains in a highly reactive state.
2. Hot-Dip Galvanizing Process
The workpieces are immersed in a zinc bath with a temperature controlled at 450–460℃. The immersion time is adjusted according to the plate thickness, generally 4–8 minutes. After plating, the zinc layer thickness is controlled by centrifugal spinning, ensuring the zinc layer is no less than 85μm, and guaranteeing complete coverage of edges and holes.
3. Post-treatment and Quality Inspection
After galvanizing, cooling and passivation treatments are performed. The zinc layer thickness and uniformity are then inspected, and samples are randomly selected for neutral salt spray testing to ensure that the overall corrosion resistance meets ISO 1461 requirements.
Application
ZBD type mounting plates have the following three typical application scenarios:
Tension string connection
Combined with tension clamps and insulator strings to form tension string assemblies.
Suspension string connection
Used for transition connections between suspension clamps and tower crossarms.
Substation frame
Serves as a transition connector for hardware components.

FAQ
Q: What are the differences between ZBD type mounting plate and other mounting plates?
A: Compared to U-shaped hanging rings, which require customization based on the bending angle of the mounting plate to prevent jamming or wear, ZBD type mounting plate offer greater adaptability due to their plate structure. Compared to trunnion mounting plates, which allow free rotation but require pre-installation during pole/tower erection and cannot be disassembled, ZBD type mounting plates offer more flexible installation and are suitable for a wider range of applications.
Q: Does the product comply with international corrosion protection standards?
A: The product strictly adheres to the ISO 1461 hot-dip galvanizing standard, with a zinc layer thickness of ≥85μm, and provides third-party salt spray test reports (such as SGS), meeting the requirements for C4 corrosion environments and complying with the EU CE Construction Products Directive.
Q: Are load performance documents provided?
A: Third-party static load test reports based on the EN 1993 standard are available, and additional certification testing can be performed according to customer-specified standards.
