Overview
We manufacture tubular and polygonal steel poles for transmission, sub-transmission and distribution lines, built to the utility's design and loading. Shafts are brake-formed from plate, seam-welded, fitted with base plates, arms and attachments, and hot-dip galvanized for long outdoor life.
Our capabilities
- 01Tapered polygonal poles: 8, 12 and 16-sided
- 02Transmission, distribution and substation poles
- 03Slip-joint and flange-joint sections
- 04Base-plated and direct-embed designs
- 05Anchor bolt cages and templates
- 06Cross-arms, davit arms, vangs and step bolts
- 07Longitudinal seam welding with weld NDT
- 08Hot-dip galvanizing or weathering steel

FAQs
Which standards are steel utility poles designed to?
Steel transmission poles are commonly designed to ASCE/SEI 48, with loads set by the utility's specification and, in Canada, the loading requirements of CSA C22.3 No. 1 and CSA C22.3 No. 60826 for the line's region.
Galvanized or weathering steel: which is better for poles?
Hot-dip galvanizing to ASTM A123 or CSA G164 gives a uniform zinc coating suited to most environments. Weathering steel (ASTM A871) forms a protective patina without coating and is chosen where a natural brown finish is acceptable and the site is not continuously wet or salt-laden.
What is a slip joint?
A slip joint connects two tapered shaft sections by sliding one over the other. The overlap is typically at least 1.5 times the inside diameter of the female section, giving a strong connection without field welding or bolting.
Who manufactures the parts?
Parts are manufactured within the Ferrokshar Group, in production since 1997. Engineering, project management and on-site support are handled by our team in Toronto, ON.
