Detailed Information:

RatnaExports.com sheets are available in various sizes, including standard and metric sizes in grades 1045, 4140HT, 303SS, and 316SS. We can also manufacture special sizes according to your requirements. The highest degree of accuracy, concentricity, straightness, and surface perfection is achieved by our TG&P bars, which meet or exceed ASTM A108 standards. A standard bearing best suits these bars, usually undersized or nominal. Its diameter ranges between 0.197″ (5mm) and 9″ (3mm), with a typical length of 12 or 24 feet.

For the Ground process, a hot rolled bar or cold drawn bar is turned in a lathe. Achieving the desired steel bar size may take more than one pass. Since the bar’s surface roughness is still relatively rough, a grinding wheel only removes a small amount of roughness, resulting in uneven wear and balancing issues. When the bar has been approved regarding dimensions, it is polished with a polishing wheel.  

Precision ground steel bars are perfect for machining in environments that require a round, straight shape with a defined tight diameter tolerance and good roundness, straightness, and fine surface finish. In machining environments that require a round and square shape, ground bars are designed to rotate at high speeds with minimal vibrations and are made from copper, stainless steel, or galvanized steel. As a result of electrical storms and high-voltage electrical shocks, the ground bar protects electrical appliances and equipment. For this reason, all ground wires in various electrical circuits are connected to a neutral bar. The neutral and ground bars are often sold together as they are commonly used together.

Ground bars can be made of various materials, but copper is the most common for a faster and easier installation. It all depends on the customer’s requirements.

Extra costs are associated with these pre-drilled holes, but they are well worth it. If you want the installation to be even easier, then you need to purchase the necessary accessories, such as clamps, cables, and brackets. If you want peace of mind when installing ground bars, you can buy kits with all the necessary parts.

Ground-finished machined bars have many benefits.

In addition to delivering short- and standard-length pump shaft steel bars, Circle H Steel specializes in supplying long bars up to 27 feet. These options offer a variety of benefits over shorter options. 

  • Raw materials produce more usable products with each piece
  • Material handling trips are reduced, resulting in lower fuel costs and fewer person-hours spent on them
  • A smaller number of pieces of material to store
  • Reduction in the number of welds, threads, or mates needed to join smaller parts
