Construction Material

The term reflective glass does not refer to mirrors only, though such glass can provide mirror-like qualities. Reflective glass has a metallic coating to help reflect heat, which in turn lowers energy costs for the building, as it takes less energy to regulate the building’s interior temperature. Reflective glass can give the appearance of a one-way mirror, providing added privacy for building occupants. Reflective glass uses consist of forming building facades and interior design pieces.

Safety Equipment, as implied by its name, includes the gadgets that are used (worn, used, suspended etc.) for the protection of life and to avoid injuries or casualties. For example, in a welding operation the dark welding helmets are used as a piece of safety equipment. In construction operations, hard hats, foot gear and coveralls are considered safety equipment. All these types of safety equipment fall under the Personal Protective Equipment category.
