Build Your Own - Aluminium balustrade system full kit

Tell us your measurements and we'll work out exactly what you need, then add it all to your basket in one click.

Measure each run outside-to-outside (the full length of the edge you want to rail), in your chosen unit, and the calculator works out the posts, rails and brackets you need for even spacing. Quantities are an estimate — we recommend confirming before ordering large jobs, and non-90° angles or custom layouts are best checked via our quote form. Bays are worked out from the real post pitch and rails are cut down for even post spacing. On short runs and tight returns the calculator automatically reuses a rail off-cut where one is long enough (one off-cut per rail), saving a rail kit and adding one fixed-bracket set and one rail-cover set instead — keep all off-cuts until the whole job is finished. Inside a section, runs join at corners and share a post; a separate section starts a new stretch. Stair runs add a bracket pack and a spacer pack per rail. Gates are added as complete units and don't change your rail or post counts — we'll confirm the exact gate layout with you after ordering.
