Spiral Rib Pipes for Storm Sewer Projects Spiral rib pipes feature better hydraulic efficiency than traditional integral or spiral corrugated pipes and they are widely used for various storm sewer projects or acting as liner pipe for rehabilitating existing culverts. Made of quality galvanized or polymer coated steel, spiral rib pipes have lock-seam structures with external ribs formed by passing through roll forming line. Decades of uses have proven spiral rib pipe is one revolutionary product[...]

Spiral Corrugated Pipe - Zinc & Polymer Coated Spiral corrugated pipes, as the best combination of strength and hydraulic efficiency, feature helical pattern and lock-seam construction in round shapes from 12" to 144" in diameter. They are manufactured from quality galvanized corrugated sheet using advanced German manufacturing technology. Meanwhile, spiral corrugated pipes can be connected by coupling systems or flange plates according to the project requirements.[...]

Galvanized Nestable Corrugated Steel Pipe Nestable corrugated pipe is composed of two semicircle sections that are bolted together to form a round corrugated steel pipe. Compared with integral corrugated pipes, this one has nestable structure, which means they can be nested into bundles for easier handling and transportation. Therefore, they are generally applied to remote projects or sites with bad construction condition. Two types of nestable corrugated pipes are available in our company as[...]
