BS 9101:2017
For best practice, installers should ensure that any gutters they fit comply to British Standard BS 9101:2017 Steel and aluminium rainwater systems.
Our standard gutters are generally compliant with BS 9101:2017*.
The standard specifies the requirements for the design and manufacture of metal gutters on industrial, commercial and residential buildings. It reflects the range of materials and manufacturing technologies available and applies to the manufacture of steel and aluminium metal gutter systems.
This British Standard specifies the materials, tolerances, mechanical properties and surface conditions, coatings, laminated surfaces, jointing methods and fixings for rainwater systems, including fittings and accessories for assembly or support.
The British Standard is available from www.shop.bsigroup.com.
*Fitting gutter using rafter or mortar brackets may compromise compliance.
