What Roscoe Moss Company does

Roscoe Moss Company is a privately-held U.S. manufacturer of water well casing and screens, headquartered in Los Angeles, California, with roots dating to the S.A. Clampett Company in the 1890s and re-incorporated under its current name in 1927. The company designs and fabricates spiral-seam steel pipe using double submerged-arc welding, and is described as the only manufacturer in the world producing both shutter (louvered) screen — offered in Ful Flo, Standard Flo, and Super Flo patterns — and continuous wire wrap screen. Product portfolio spans water well casing, multiple corrosion-resistant steel grades (mild, copper-bearing, HSLA, austenitic 304/316, and duplex 2101/2205/2507 stainless), well accessories, water transmission pipe meeting AWWA C-200, the Storm Flo stormwater gross solids removal device certified as a California Full Capture System, and the Rossum Sand Tester (AWWA A100).

The company operates four facilities — Los Angeles (HQ and manufacturing), McFarland and Fontana (distribution and fabrication), and Roscoe Moss Sahara in 6th of October City, Egypt — and holds a 1993 joint venture with Tuberia Laguna S.A. de C.V. in Torreon, Mexico. Its customer base spans municipal water agencies, agricultural growers, mining operators, and commercial water users across more than 50 countries on six continents. Revenue is generated through B2B direct sales of project-tied hardware specifications, supplemented by a small e-commerce channel for Rossum Sand Tester kits and replacement parts (priced $1.60–$800). The firm is family-held, has 101–250 employees, and has remained private throughout its 100+ year history with no disclosed external funding.
