We custom fabricate and sell pipe to customers serving construction segments such as building construction, road construction, bridge construction, utility construction, marine construction, and oilfield construction just to name a few. Our Welded Steel Pipe finished products are installed by those performing horizontal road boring, directional drilling, and pile driving procedures for these industries. We have two specialty niches. The first includes fabricating 20' dead length stock sections for use as Steel Casings, such as Road Bore casing, Culvert casing, Open Cut casing, Open Tunnel casing, and Water Well casing. The picture above shows some of these 20' sections on our yard. The second includes custom fabricating Steel Pipe Pilings, such as Foundation piling, Bridge piling, and Marine piling, including pier pilings, dock pilings, and deep water pipe pilings to length.
