Hot dip Galvanized U Post
Classification: Galvanized U Post
Brand Name: FORST
Brief introduction:
The hot-dip galvanizing process of the U post of the guardrail soaks the steel product in the molten zinc solution to coat the zinc layer to enhance the corrosion resistance and durability of the U post of the guardrail. The specific process is as follows:
1. Pretreatment: pickling, cleaning, degreasing and derusting the surface of the guardrail U post to ensure the surface is clean. This is an important step to ensure the quality of hot-dip galvanizing.
2. Soaking and dipping: immerse the pretreated U post of the guardrail in the molten zinc solution, and coat the zinc layer under certain temperature and time conditions. The length of galvanizing time is directly related to the thickness of the zinc layer, generally 3-10 minutes, and the thickness of the zinc layer is 60-100μm.
3. Polishing: The dip-plated guardrail U post will be polished to improve its surface quality.
4. Cooling: Cool the polished U-shaped column of the guardrail in the cooling tank. This will help to accelerate the crystallization and solidification of the zinc layer, while also ensuring the quality of the zinc layer. The hot-dip galvanizing process can significantly improve the corrosion resistance and durability of the U post of the guardrail, thereby prolonging its service life and reducing maintenance costs.
U post is a kind of steel with a flow phase just like the english letter "u". its primary dispositions are: immoderate stress, prolonged assist time, easy set up and easy deformation.
