Sets out procedures for the selection and installation of metal rainwater goods complying with AS 2179. It also includes design factors for internal box gutters and a method for sizing of gutters and downpipes.

This standard sets out procedures for the selection and installation of metal rainwater goods complying with AS/NZS 2179.1. Where necessary, designers should take proper precaution to provide for hail and snowfall conditions.
