Trench Shoring Company supplies construction contractors with trench protection equipment, underground shoring systems and related jobsite products, covering projects from small utility trenches to major public works and sewer-line construction. Its technical range spans trench and excavation shoring systems, hydraulic shoring, slide rail systems and trench box engineering. Product lines include Flex-Shield trench boxes, Z-Shore hydraulic shoring, slide rail systems, trench and manhole boxes, mechanical screw jacks and shoring beams, alongside steel road plates, traffic-control products, pipe-testing equipment, confined-space and fall-protection gear.

The company was founded by Tom Malloy in 1973 and is headquartered in Compton, California. A network of locations serves Northern California, the San Joaquin Valley, Southern California, Sacramento and Las Vegas, Nevada. The firm commits to same-day service and on-site equipment delivery, and provides consultation before excavation begins.

Through Trench Shoring University, the company runs instructor-led safety training, including OSHA competent-person training for trenching and excavations and confined-space entry training. Safety is treated as a core operating priority, supported by an emphasis on reliable inventory availability and practical, hands-on assistance for contractors working in demanding underground environments.
