Kauaʻi Manufacturing

HPM Kaua‘i offers trusses and wall panels that are manufactured right here on the island of Kauaʻi. As a locally-owned company serving Kaua‘i for over 10 years, we understand the importance of supporting our local economy. That's why we made the decision to manufacture our engineered wood products in-house rather than importing them from off-island. Our on-site truss plant utilizes state-of-the-art equipment to produce wall panels and trusses to meet each customer's unique specifications. By keeping the manufacturing local, we not only provide jobs and support small businesses, but we're also able to closely oversee quality control and quickly fulfill orders for our neighbors building homes and commercial properties across the Garden Island.
