Technical data for columns & masts
The performance data for columns and masts gives their basic technical attributes only. The technical performance of a column or mast will be affected by local site conditions (terrain type, distance to sea, site altitude, windspeed) and the headload being carried.

Please Contact the Abacus Technical team to confirm the suitability of a column or mast for your application.
