The Trellidor Aluminium Retractable Security gate is elegant and uncluttered with no visible rivets. It is ideal for environments such as coastal areas as it is made from structural steel to avoid the corrosion problems associated with these conditions and to provide additional strength. These gates are top hung and engineered to open and close smoothly. They are fully framed to enhance their strength.
