About Armorcast
About Armorcast
Armorcast Products Company has supplied the utility industry with secure, protective enclosures since 1966, building its reputation on polymer concrete research and product development under the Armorcast name. Headquartered in Chatsworth, California, the company became a go-to source for underground and at-grade utility protection equipment.
The product range includes utility enclosures, covers, handholes, barricades, junction and pull boxes, equipment pads, and detectable warning surfaces, manufactured from polymer concrete, fiberglass-reinforced polyester, and rotocast polyethylene depending on the load rating and environment. The patented Voltek vault replacement system, a panelized structural composite solution, is a notable example of the company's engineering approach to replacing decaying underground utility vaults.
Hubbell acquired Armorcast Products in January 2021, and the business has continued operating under the Armorcast name with annual revenue around $35 million as of 2025. Buyers on ChatMRO can describe enclosure dimensions, load rating, and material preference to find the right Armorcast part for a utility, telecom, or municipal project.
