According to the different environment of the project, the anti-corrosion protection requirements for the selected bridges are also different. Usually, there are many ways to treat bridges, such as plastic spraying, electro-galvanizing and hot-dip galvanizing.
High-quality, high-standard surface treatment requires the use of advanced equipment and technology, the selection of high-quality raw materials, and the products produced should have:
1, smooth and plump in appearance.
2. The coating is bright and beautiful.
3, strong adhesion
4. Strong impact resistance
5, strong corrosion resistance
6. Strong weather resistance and flexibility
In addition, pretreatment plays a key role in the surface treatment of steel materials, and its adhesion and impact resistance are the most important. At least 8 treatment processes (degreasing, water washing, derusting, water washing, surface adjustment, zinc phosphating, water washing and hot water ironing) shall be provided, so that the structural parts can be treated in the best position and the treatment effect is the best.
