In order for us to get a quick quotation out to you we will require some approximate sizes. If you could measure your structural opening in both width and height prior to giving us a call it will really help to speed the quotation process along. Try to measure in mm or cm as we need to convert imperial measurements in order to quote and manufacture. The will not be final sizes, they will only be used to give you an approximate cost for your roller shutter, garage door, steel door or retractable gate.
