At United Rock Products, customer commitment comes first
First mined in 1929, United Rock Products is a 300-acre plant located in IrwindaleŚ just 25 miles east of Los Angeles. There, virgin aggregate material is processed into sand and gravel through cutting-edge crushing and screening operations. Whether by making custom blends or creating new products, we have the knowledge and commitment to meet even the most specialized customer needs.
A plant designed for efficiency
Our automated truck loadout system consists of twelve bins situated above truck scales. This state-of-the-art system can load, weigh and ticket in as little as one minute. What's more, close freeway access allows our customers to be on the road and delivering material to their job in a matter of minutes.
Commitment to the community
Our goal is to reclaim the depleted quarries after the reserves have been exhausted. This allows the land to be reused for commercial or residential development projects. This process is important because it enables our participation in the revitalization of Irwindale and surrounding communities.
