Galvanized Culverts
Galvanized CSP are the traditional building product used for drainage under roadways, driveways, parking lots and more. They generally will offer a 15 – 25 plus year service life while providing relatively high strength capacity for traffic loads. These culverts come in varying gauges, lengths and profiles.
Our Stock of Galvanized Culverts include the following sizes:
300mm (12″), 400mm (16″), 450mm (18″), 500mm (20″), 600mm (24″), 800mm (32″), 900mm (36″), and 1200mm (48″)
Aluminized Culverts
Aluminized CSP have a higher grade coating on the steel pipe which offers greater resistance to oxidation (rust) and therefore a longer service life.
Polymer Laminated Culverts
“Poly lam” or also known as “trench coat” culverts offer superior service life and resistance to turbulent water and soil condition than both galvanized and aluminized coatings.
