HistoryLong before the creation of the industrial bread slicer, Corrugated Steel Pipe was invented in the United States.  Corrugated Steel Pipe was first used for hydraulic cross culverts in the early 1900s.   Since the first culvert application, Corrugated Steel Pipe has been used in many different construction applications. Efficiently Engineered

Contech Slotted Drain™ is used effectively to intercept storm water runoff from wide, flat areas such as parking lots, municipal streets, highways, and airport runways and taxiways. In these installations, the slotted drain is placed transverse to the direction of storm water flow or snow melt runoff. The open grate intercepts all the flow

Over the past 12 months, the entire construction industry has experienced unprecedented raw material increases in both underground piping and vertical building. With some products, raw materials costs have tripled. In addition to these exponentially rising material costs, raw material availability for thermoplastic resin has been limited in many

Are you looking for a culvert pipe to stand up to salt and brackish water environments?Corrugated Aluminum Alloy Pipe (CAP) has superior corrosion resistance and excellent abrasion resistance, which allow it to be installed in a much wider environmental range than traditional galvanized corrugated metal pipe. The rugged 3004-aluminum alloy core is

The design of highways and streets requires a delicate balance between the physical demands of a project and the realities of everyday constraints. From feasibility studies to planning, design, procurement, construction supervision and post-construction assessments, there are many different facets that must be evaluated to ensure optimal efficiency
