Engineered for Excellence

We incorporate the highest quality materials available today.


Attractive Female Molds

Each product offers a smooth exterior finish that is more attractive and non-porous. Trench covers offer a non-skid, diamond-patterned traction surface for pedestrians or vehicles (H-20 ratings available upon request).



Our products are easier to handle for a quick installation, so there's no need for bring out the large machinery equipment.


Superior Strength

We use the highest glass reinforcement content in the industry, and incorporate double layers of 24-ounce woven roving reinforcement cloth for ultimate strength.


Marine Grade Gel-Coat Finish

We finish each product by coating them with one of the industry's finest U.V.-protectant gel coats available, increasing the longevity of your product. The marine grade gel-coat finish even gives 9x the abrasion resistance of non-gel-coated products and is more resistant to string trimmers.
