They are bolted by corrugated structural steel plates on job site reducing transportation cost. CMP pipes and arches are always given optimum choices not only because their lightweight and excellent performance against harsh environments and cold weather, but also significant reduce of cost and construction time. And conventional concrete structures are progressively replaced for they need regular maintenance and huge cost.

Zinc coatings are available in two types: Z610 (610g/m2) and Z275 (275g/m2). Both are treated with hot-dip zinc galvanization which performs as a durable barrier over the base steel. Z610 offers more than 50 years of service period. Calcium from the hard groundwater effectively aid in forming an additional protective barrier on the surface of the pipe. However, Z275 is light galvanized and often used as temporary application such as oilfield lease roads or forestry purposes.
Note: Polymer coating as an optional coating in only offered for special order.
