Contact us with your project details. We can advise what is needed, and provide structural calculations for what we supply. Please note that our windposts need to be cut and drilled to suit requirements on site. All cut edges should be treated with cold galvanizing paint or bitumen (eg. Blackjack). Overview · This windpost is a 105mm deep ‘C’ fabricated in accordance with BS EN 1090. · This post is intended to be located within the cavity of a cavity wall. · All steel has been hot dipped galvanized to ensure longevity. The load capacity of this windpost at 3m length (105x55x4) is slightly greater than Ancon WP3 95x60x5 at 3m length, but slightly less at 2.5m length due to tie capacity (11.42kN vs. 13.83kN) (checked 28.04.25). The load capacity of the 3.5m and 4m length windposts (105x65x6) are slightly greater than Ancon WP3 115x60x5 at lengths 3.25m and above. Load capacity of the windposts at lengths below this are slightly less than Ancon WP3 115x60x5 due to tie capacity (15.03kN vs 13.72kN at 3m length) (checked 28.04.25). · This post is provided with a welded base plate as standard. In many cases no additional base connector is required. · The load capacity of this windpost has been determined by our in-house structural engineer, who is also on hand to answer any technical questions you may have. · This post can be supplied with all frame cramp wall ties, Tek screws and isolation pads required. See the options in the drop-down box to see which you need. · A variety of base and top connectors are available to suit most applications.
