Company Overview

Hannibal Industries, Inc. is a diversified, value-added metal fabricator, located in the Los Angeles area, with two primary divisions offering carbon steel tubing and pallet racking systems to our customers.

Incorporated after purchasing the assets of Kaiser Steel Tubing, a division of Kaiser Steel Corporation in 1985, our tubing division currently maintains six high frequency tube mill lines that are capable of producing 120,000 tons of tube a year.

Mitsui & Company (U.S.A.) acquired a portion of the company in 1987, and then secured company assets in 1999.

In 1997, all outstanding common stock of Rack and Roll, Inc. were acquired and became what is known today as our storage systems division, which currently provides roll-formed and structural pallet rack, cantilever rack, dynamic storage solutions, and several more products and services.

A new tube production facility was commissioned with a Rafter Four (4) inch Tube Mill, Haven Cut Off and End Finishing Line in 2003 to produce high quality round tubing for critical surface applications.

Always working to improve its storage systems options, Hannibal was awarded a patent in 2006 for an adjustable safety restrain to contain stored products within a pallet rack system.

The quality management system of Hannibal’s tubular products division is ISO 9001:2008 certified. We take pride in our quality management system and the superior products and services that result from those efforts.

On March 20, 2008 Hannibal Industries, Inc. became an employee owned company through the creation of an Employee Stock Ownership Plan (ESOP).

We continually strive to improve customer satisfaction and promote a positive and motivational environment for its employees and those involved with our diversified metal business.

Company Overview

Leavitt Tube Company began producing mechanical steel tubing in 1956. Fifty years later, we’ve evolved into an industry leader with one of the broadest size ranges of Structural, Mechanical and Hi-Y50 Pipe Size Tubing in the industry. Currently, we’re headquartered in Chicago, Illinois; we operate ten tubing mills with facilities in Chicago, IL and Jackson, MS.

We’re known throughout the industry as “The Tube People“, and our employees pride themselves on providing quality tubing and unparalleled customer service.

In 2008, Maruichi Steel Tube LTD of Japan acquired a majority interest in Leavitt Tube.

Maruichi Steel Tube LTD, founded in 1947, has developed a global business model by establishing manufacturing companies in Japan, the United States, Indonesia, China, Vietnam and India. With over $1.5 billion in sales and total production of more than 1.5 million tons of steel tubing, Maruichi Steel Tube is highly regarded, and is one of the world’s largest manufacturers of welded steel tube.

With “The Tube People’s” commitment to providing outstanding customer service and Maruichi’s dedication to the production of the highest quality tubing, Leavitt Tube will remain an industry leader for generations to come.

Leavitt TubeCompany will work with our customers, suppliers and employees to determine and exceed their expectations.

Leavitt has adopted the Japanese 5S methodology as a way to organize andmanage our workspace more efficiently. This methodology uses a list of five Japanese words which each start with the letter “s” when translated into English; hence, the “5S” designation. We’ve implemented this methodology to improve efficiency and flow by eliminating waste. “5S” not only improves workflow and sets standardization, it helps to promote a safer working environment.

Leavitt Tube Company is based in Chicago, Illinois and has ready access to raw materials and transportation, including rail, major highways and ports. From here, we ship product by truck and rail to serve customers throughout North America. We maintain two production locations comprising more than 1,000,000 square feet.
