TerraCast® has a trademarked process called PolySteel™ that we use to build our resin-blended lampposts.
We use a unique proprietary blend of resin combined with galvanized steel, and industrial plastic foam. This combination creates a superior light pole that is impervious to the environmental elements to which every other material is vulnerable.
Our resin products are made by rotational molding, that allows us to create an exceptionally strong pole.
We start with a core of galvanized steel, for strength. That core is carefully and thoroughly encased in a thick layer of polyurethane foam, another light plastic, which isolates the core and gives the piece its general shape. The outer skin is a quarter-inch of Linear Low Density Polyethylene, or LLDPE, which makes the final shape and detailing. The finished product is a light pole that is impervious to the elements.
Many elements will cause a traditional steel or aluminum light pole to begin losing integrity. Our poles are not susceptible to corrosion or pet waste that causes decomposition. Another problematic aspect to metal poles, are thieves who steal loose metal parts for scrap. Since our resin poles do not have any outer metal, we avoid thieves damaging the look of our posts. Our PolySteel™ composite light poles stand tall in the face of abuses that other products are victim to.
Our three-part process forms a true composite light pole:
1. Strong Core
2. Thick protective layer of polyurethane
3. Outer skin of indestructible resin
The end result is a beautiful, decorative, tapered and fluted line of light poles that are impervious to damage that plague other types of light poles.
