It is a gifted idea to make integral corrugated metal pipe into Semi-circular metal culvert pipe, which enables the factory to load 4-6 times more in the same container, thus tremendously promoting foreign trade of this widely-used product.
By corrugating and curving the steel sheet into semi-circular parts, we can pack them on a standard pallet (wooden or steel), and load them into the container directly with a forklift. After arriving at the wholesaler's warehouse or the job-site, these semi-circular metal parts can be unloaded in the same way quickly.
Basically, there are two ways of installing available: flange-joint or nestable joint, that is why this product is also usually called nestable metal culvert pipe. For both connecting methods, enough bolts and nuts are needed.
Two pieces of semi-circular metal culvert pipe parts are placed on the ground, one up and one down.
Side flange design makes the installation of semi-circular metal culvert pipe easy and convenient.
By the bended side flanges, we join two pieces of polymer coated semicircular culvert pipe sheet together with bolts and nuts.
Two workers are installing nestable semi-circular metal culvert pipe in over-lapped way.
Dozens of semi-circular metal culvert pipe parts are packed on a pallet, fastened by steel tapes, and enclosed by plastic cloth.
Look! We can load dozens of semi-circular metal culvert pipe parts into the container once, easily and conveniently.
