Metal Culvert Seel Pipe manufactured by Lucky Steel is made of multiple corrugated plates connected with bolts.

It has many advantages, such as thin plates with light weight, easy to transport and store, simple construction technology, convenient on-site installation suitable to deal with the structural damage of bridges and pipe culverts in the cold areas.

Longitudinal articulation molding is carried out. M20, 8.8 grade high-strength bolts and arc washers are used for connecting bolts, side seams and bolts are treated with sealant, and the appearance of the steel plate is hot-dip galvanized. After the assembly is completed, the asphalt is sprayed. The paving and slope protection of the hole are paved with M7.5 slurry stone or reinforced concrete to pour the hole.
