Corrugated steel pipe (CSP) has been a staple in various infrastructure projects due to its strength and flexibility. However, its durability has historically been a point of concern, particularly with galvanized steel, which has shown suboptimal performance in certain environments.

Metallic coatings have been applied to iron and steel armaments as early as the 17th century. The purpose of metallic coatings applied to steel is to help retard corrosion. The zinc coating process of steel, referred to as galvanizing, was name after Luigi Galvani, an Italian physicist who lived in the 18th century. Galvanized steel in the construction industry came into widespread use in the early 20th century.

We’re excited that DuroMaxx® Steel Reinforced Polyethylene (SRPE) has been accepted for use by the Georgia Department of Transportation (GDOT). DuroMaxx is now an approved material type for drainage and culverts applications that can be considered on DOT projects all across the state of Georgia! DuroMaxx has continued to gain traction nationwide as DOTs evaluate the quality of its structural components and see the in-field performance results of this innovative product.

Long 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.

I know you all have been waiting with baited breath to find out the in's and out's of the last two considerations when evaluating a large diameter flow thermoplastic sewer solution. To recap, typically, the larger diameters tend to have far less directional changes and lateral connections. Also, interceptors tend to have deeper heights-of-cover in gravity flow applications. Many interceptors are designed to flow 50% to 70% full, with minimal slope, deep covers, and within groundwater (requiring dewatering installation). It is also not unusual for new interceptors/trunks to be miles of pipe using several diameters.

The need for large and ultra-large sanitary sewers is growing as community populations and conveyance flow requirements increase. Many expert studies have estimated that the sanitary sewer market will grow at a 6% compound annual growth rate (CAGR) in the coming years. With this growth, alternative materials, such as thermoplastics, are being designed more frequently due to the corrosive sanitary sewer environment.

If you were to work at a firm for 50 years or stay married to the love of your life for 50 years, would you say that was a remarkable milestone? Would one
