Corrugated steel culverts have dominated the culvert application market since they appeared in the construction industry more than 100 years ago. Corrugated steel culverts, storm drains and subdrains are critical to protecting streets, highways and railways.
As the demand for cost-effective, durable infrastructure has grown over the years, the bellows industry has responded.
Technological advances have provided more hydraulically efficient profiles and highly durable coatings such as spiral ribbed tubes, polymer coatings, aluminized 2-shape steel and 2-ounce galvanized steel.
Corrugated steel pipe and plate culverts provide a reliable, economical solution to handle water flow, including debris, with minimal damage to slopes or culvert barrels.
