This is the one of the most popular of all external awnings and is widely used on shops, restaurants, hotels and on domestic properties.  Either retractable or non-retractable (see wet look blinds).

The quarter circle shape is formed by four or five legs, depending on the projection,  from anodised aluminium extrusion and held together by metal or plastic components and rivets.  The profile has a channel into which a PVC extrusion is inserted and to which the blind fabric is stapled and then covered by tape.  The blinds can be housed under an aluminium top board and end cheeks if required.
