introduction

The production line is a fully automated production line integrating uncoiling, leveling, punching, cold bending forming, bending arc, cutting and integration of production equipment with a variety of technologies, such as uncoiling/steering, forming, cutting, automatic feeding, stamping, automatic receiving, off-line bending and arcing. The whole production line is composed of unwinding/drawing system, forming system, automatic conveying/positioning system, punching system, automatic receiving system, arc bending system, electrical control system, etc.

The Culvert Corrugated Plate Roll Forming Machine is a specialized, high-performance equipment designed for the mass production of corrugated steel plates used in culverts, tunnels, and drainage structures. As a critical production tool in the transportation, water conservancy, and municipal infrastructure industries, it is engineered to transform high-strength steel coils (such as Q235, Q355, and galvanized steel) into corrugated plates with precise waveforms, excellent structural rigidity, and strong load-bearing capacity. These corrugated plates are widely used in the construction of highway/railway culverts, underground drainage channels, tunnel linings, and small bridges, thanks to their advantages of quick installation, corrosion resistance, and adaptability to complex geological conditions.

Integrating advanced precision forming technology, intelligent control systems, and heavy-duty structural design, the machine ensures consistent quality of corrugated plates, fully meeting the strict technical standards of infrastructure projects for material strength and dimensional accuracy. It is an ideal choice for steel structure manufacturers, construction engineering companies, and municipal construction units engaged in culvert construction.

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.

Our Advantage：

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.
