Hi Gilly, sorry for the delay in posting an update about this - you've probably got sorted out now. But in case you haven't, we ended up using Ten Metals on Gunlukbasi road. Whilst we are happy with the product and the price, we experienced a number of delays in delivery, and had to resort to the threat of legal action to get our deposit back - this worked, and the glass panels were installed a week later. Because of this worrying, uncomfortable experience, we would not recommend them.
