Product Specification

  1. One-piece thermoset-molded offset reflector: This suggests that the reflector is made from a single piece of thermoset-molded material. Thermoset refers to a type of plastic that, once set, cannot be melted or reshaped. The “offset” design indicates that the reflector is not a standard symmetrical shape but is positioned or shaped in a way that serves a specific purpose, often related to optimizing light distribution.
  2. Plated hardware for maximum corrosion resistance: The hardware, which includes nuts, bolts, screws, etc., is plated with a corrosion-resistant material. Plating helps protect the metal from corrosion caused by exposure to elements such as moisture, air, or chemicals.
  3. Pre-galvanized construction: This indicates that the construction material, likely steel, has been galvanized before the final product is manufactured. Galvanization involves coating the steel with a layer of zinc to protect it from corrosion.
  4. 500-hour salt spray hardware: The hardware has undergone a salt spray test for 500 hours. This test is a common method to evaluate the corrosion resistance of materials and surface coatings. It simulates the corrosive effects that can occur in a salt-laden environment, such as coastal areas.
