1. Different galvanized concrete anchors principles
wedge anchor hdg: Immerse steel components in molten zinc to obtain a metal coating.
Cold-dip galvanizing wedge anchor: After degreasing and pickling, the processed steel components are placed in a zinc salt solution, connected to an electrolytic device, and a layer of zinc is deposited on the steel components using the electrochemical principle.
wedge anchor zinc plated: Different passivation solutions produce different colors of passivation films, and their corrosion resistance will also be different, so there are different process names; the color of the galvanized wedge anchor layer is determined by the passivation process, and there are silver-white, blue-white, color (multi-color military green), black and other processes.
Usually the corrosion resistance of galvanizing decreases from strong to weak: military green passivation > black passivation > color passivation > blue-white passivation > white passivation
2. Different equipment required
hot dipped galvanized wedge anchors: pickling equipment, bottom-drawn annealing furnace or bell-type annealing furnace.
Cold galvanizing wedge anchor and color galvanizing wedge anchor: electrolytic equipment.
3. Different performance and advantages
Goodfix & fixdex self-owns multi pieces of surface treatment lines, implements Closed-loop
production of the entire industrial chain.
Hot dip galvanized wedge anchor(HDG wedge anchor bolt): durable and corrosion-resistant, the standard quality hot-dip galvanizing anti-rust thickness makes it extremely durable; the coating has strong toughness, and the hot-dip galvanized zinc layer forms a unique smelting metal structure that can withstand mechanical damage during transportation and use
Cold galvanizing: has good environmental performance. Most cold galvanizing solvents and diluents do not contain highly toxic organic solvents, and the cold galvanizing process also reduces the volatilization of organic solvents, reduces drying energy consumption, and is beneficial to environmental protection.
4. Advantages of hdg wedge anchors
hot dipped galvanized wedge anchors: Due to its good anti-corrosion performance, galvanized wedge anchor bolts is widely used in power towers, communication towers, railways, highway protection, street lamp poles, marine components, building steel structure components, substation ancillary facilities, light industry, etc. The color of hot-dip galvanizing is silver-white with a light blue hue, and some of the colors after chromate passivation are silver-white with a light rainbow hue. Its exact color can be seen from road poles and highway guardrails.
Cold galvanizing anchor bolt: Cold galvanizing is the main development direction of environmental protection of heavy-duty anti-corrosion coatings.
