I have a bi-fold door which needs a curtain across it. Its 260cm wide with a 220cm drop. the curtain is ordered but I now need a heavy duty curtain pole to take it. I want one rigid enough so that it doesn't need a centre support and I don't need to faff around with c-rings. I'll be drilling through plaster and into breeze blocks to support it. Does anyone know of something that could fit the bill.
