1. Production Process: Assembled metal corrugated pipes are made by first folding Q235 steel plates into corrugated sheets and then bolting them together; fully assembled metal corrugated pipes are made by first bending and welding steel plates into a barrel shape, and then folding them using a folding machine.
2. Difference in Transportation Difficulty: Assembled metal corrugated pipes save more space than fully assembled ones. A large truck can carry 20 meters of fully assembled metal corrugated pipes with a diameter of 2.8 meters, but an assembled one can carry more, making transportation simpler.
3. Difference in Installation Methods: Although assembled corrugated pipes are easier to transport, they also have disadvantages. The biggest problem is that the installation process is much slower than that of fully assembled ones, requiring specialized technicians to assemble them on-site; fully assembled metal corrugated pipes are relatively simple to install.

Shorter corrugated culverts can be pre-assembled in the factory and then transported as a whole to the construction site for direct hoisting and installation. Longer culverts are transported in sections, transported to the site first, and then assembled on-site. Large-diameter culverts (diameter ≥ 3.0m) are typically transported in sections using sheet-like arc-shaped corrugated plates and assembled on-site with bolts.

Whole pipe transportation: More suitable for projects with smaller diameters, good road conditions, and a need for rapid installation.
Assembled unit transportation: Ideal for large-diameter culverts or projects located in remote mountainous areas or other areas with inconvenient transportation.
