Key Features
- Each Stemco Column covers a wide load range.
- Top Plates are designed to accept multiple beam widths.
- The 8'- 6" column lengths can be used for 8' and 9' basements.
- Large threaded ends are very durable and easy to adjust.
- 3" extension adjustment is available on all columns. Easily adjusted with only a bar or wrench.
- The square tubing can be easily trimmed to length on site.
- Top grade Canadian Structural Steel Construction.

The
above columns have been designed and tested to meet the requirements
of the NBC and ABC parts 4 and 9. NOTE - The above column capacities are based on concentric loading of the column or a single beam covering the entire top bearing plate. If two beam ends are supported on one column, consult our "Spliced Beam Calculation" in the Printable Brochures section of our website. |
