Guardrail beam FORST

Guardrail zinc layer treatment methods usually include the following:

1. Hot dip galvanizing: the guardrail components are first de-oiled and de-rusted, and then immersed in the molten zinc liquid to form a uniform and dense zinc layer on the surface of the components through a chemical reaction.

2. Electric galvanizing: The guardrail parts are galvanized by electrolysis, that is, zinc sheets are placed on the surface of the parts as an anode, and zinc ions are deposited on the surface of the parts to form a zinc layer through the action of current.

3. Zinc spraying: Special spraying equipment is used to spray zinc powder or zinc alloy on the surface of the guardrail parts. Spraying zinc layer can form a dense and uniform zinc layer, which has good anti-corrosion properties.

4. Thermal spraying zinc: the zinc strip or zinc wire is heated and melted, and then high-pressure gas is used to spray the melted zinc to the surface of the guardrail parts to form a zinc layer.

The above is the commonly used guardrail zinc layer treatment method, the specific choice of which method should be determined according to the actual situation and needs. In the process of use, it is also necessary to pay attention to regular inspection and maintenance to ensure the integrity and corrosion resistance of the zinc layer.

Guardrail production process to go through the selection of materials, rolling molding, pickling, galvanizing, passivation and other processes, after the completion of production will be stacked one piece, pay attention to the stacking process, each piece of guardrail to place the dividing rope, generally 20 pieces, or 25 pieces piled into a pack, and then tied up with metal cable, convenient forklift or other mechanical tools to handle the guardrail.
