HEL-COR service life exceeds 100 years with proper specification that meets all AASHTO and ASTM pipe specifications, and it can handle fill heights in excess of 100 feet.
A wide choice of coatings including galvanized steel, aluminized steel type 2 (ALT2), and polymer-coated steel are available to meet a variety of durability requirements. A variety of wall thicknesses (gages), corrugations, diameters, and pipe section lengths permit a choice of materials to meet specific job site requirements.
Standard fittings include tees, wyes, elbows, saddle branches, reducers and manifolds for detention systems. Manholes and catch basins can be fabricated to meet specific job requirements.
