Flanged Steel Pole

The Flanged Steel Pole is a steel pole with flanges at each segment end. A flange is a flat steel ring with bolt holes. We divide the pole into two or more sections. Each section has a flange welded at the top and bottom. At your site, your crew bolts the sections together. This is much simpler than welding sections in the field. The flange connection is strong and reliable. It is ideal for projects with limited transport access.

03 PRODUCTION EQUIPMENT

Segments That Fit Your Transport Route
The Flanged Steel Pole works well when the full pole is too long to transport. We divide the pole into segments based on your transport limits. Each segment can travel on a standard flatbed truck. We help you choose the segmentation points. We ensure the flanges are at convenient heights for assembly. This flexibility makes the Flanged Steel Pole a practical choice for mountainous or congested areas.

04 OVERALL VIEW

Precision Flange Fabrication
The flange is the most critical part of this pole. Every bolt hole must align with the matching flange on the next segment. We use CNC machines to drill the flange holes. The hole pattern matches exactly. The flange face must be flat. We check the flatness after welding. If the flange warps during welding, we re-machine it flat. This precision ensures your crew can bolt the sections together with ease. No reaming is required.

Bolting for a Secure Fit
Our Flanged Steel Pole uses high-strength bolts for the flange connections. We supply the bolts, nuts, and washers. The bolts are tightened to a specific torque. Our instruction manual provides the torque values. The bolted connection is as strong as a welded joint. It also allows for future modifications. Your team can add extensions or change equipment configurations more easily with flanged connections.

Saving Time on Installation
The Flanged Steel Pole reduces installation time significantly. Your crew does not need to weld on site. They simply lift each segment into place and tighten the bolts. This is faster and safer than field welding. Our engineering team provides detailed assembly drawings. The drawings show the bolt tightening sequence. We also include a list of required tools. Everything is ready for your crew.
