Production Process Flow
The products of the production line are carried out according to the following technological process:
Uncoiling → traction leveling → looper (material storage)→ servo leveling feeding → punching → looper (material storage)→ cold bending molding → cutting → material code.  floor plate bending roll forming line

Advantages of culvert plate rollforming machine
1. Corrugated steel culvert has both rigidity and flexibility; The structure has reasonable stress, uniform load distribution, and has a certain anti-deformation ability.
2. Adopt standardized design and mass production in the factory; Short production cycles and high efficiency are good for reducing costs and improving quality.
3. The site installation speed is fast, the construction period is short, and the social and economic benefits are obvious.
4, construction can be carried out throughout the year, the construction is not affected by the season and the environment.
5. It can effectively solve the problem of damage to concrete Bridges and culverts caused by repeated frost heave in cold areas of north China.
6. It is especially suitable for long-term use: eastern soil, expansive soil, soft soil, collapsible loess and other special areas, which can avoid the destruction of culvert caused by uneven settlement due to foundation deformation.
7. Reducing the use of conventional building materials such as cement, sand and stone has profound implications for environmental protection.
8, the same span of corrugated steel bridge culvert is lower than the concrete bridge culvert.
