JMC Steel Group's Pipe and Piling Division, Atlas Tube operates out of Chicago, IL USA and Harrow, ON Canada operations. Atlas Tube is North America's leading producer of Straight seam ERW steel pipe. Our ERW straight seam product can be found in many applications such as Geotechnical and Deep Foundation applications for load bearing and friction steel pipe piles.- ASTM A 252 Grades 2 and 3. In fact, the high quality of the product make it a perfect choice for state and federal DOT, USACE, Energy, Civil, Private and Government projects. In addition, it can be used for road boring, marine, structural and casing applications.
Our most common grades of steel are structural grade ASTM A 500, along with piling grades ASTM A 252, modified ASTM A 252 with 50 or 60 KSI minimum yield strength. In Canada, Atlas offers A 500 and CSA G40.21 out of stock and piling grade A 252 off our mill rollings. High Strength Low Alloy (HSLA), Copper Bearing (CU), along with other special grades of steel is also available for unique design build projects. Our steel pipe piles are spec for use both on friction and load bearing geotechnical applications. Our own staff metallurgist is available to consult with your team to address your specific issues and find economical solutions.
As an added value, JMC provides MTR documentation that includes the following:
- Complete Heat Traceability
- Chemical Analysis
- Tensile Properties
- Charpy Impact Testing
In the USA, each piece of piling Atlas manufactures is bar coded and has an original Mill Test Report (MTR) from the producing mill. All mill MTR's are backed by coil certificate from our suppliers which are reviewed before the coils are shipped to our plants. This procedure ensures that the product meets the highest quality requirements. Look at the mill stencil and heat number on a pipe or the MTR and you will have probably seen JMC – Atlas Tube piling on your project. Atlas has your back covered with our ISO quality procedures (ISO 9001:2008 certified).
In addition to the MTR documentation, Atlas provides fabrication services. We can bevel the ends and attach driving shoes in order to deliver the product to you in a cost effective manner and save on site labor. Many names have been given to the applications of our products by our customers: pipe piles, driven piles, drilled shafts, caissons, mini caissons, micro piles, piers, and casings. Call it what you want, we have the strength to deliver.

Definitions
Pin Piles - Range from 2-6 inches in diameter. Design and installation requirements are based of the individual project requirements, size and type of pin pile design for the project, soil conditions, each can vary from project to project. Common along the coastal cities in the USA and Canada.Micro Piles – Range up to 14 NPS in diameter. Design for high capacity small diameter steel casing used as reinforcement in structures where engineering challenges and usable space on site come into play. Common in older buildings and historical sites..
Skin Bearing Piles –Range up to 20 NPS in diameter. Design where the driving of the pile into the earth causes the earth displaced by the driven piles to compress surrounding the driven pile causing friction onto the sides of each pile.
Load Bearing Piles – Range up to 20 NPS in diameter. Design as the name calls out. These piles are driven into rock to bear the loads of the structures they support.
A Tube Mill Overview
All tube mills require a minimum level of equipment to accomplish the basic task of producing tube (Figure 5). The entry section of a tube mill will feature some means to unroll the strip from its coil form, and a way to join the end of the last coil to the beginning of the next. All tube mills will feature a series of tooling to form the strip into tube, and a welding station to join the seam of the tube, followed by some method for cutting the tube to length. Some mills feature additional equipment to make the operation more efficient, or to add special features to the tube. The headings that follow identify the equipment common to most tube mills, as well as some of the specialty equipment that may also be featured on a particular mill.
