Stratco can manufacture any custom rainhead design to suit your building’s architecture. Choose from one of our standard styles of rainhead; including Box, Curved, Tapered, Round or Segmented. Rainheads are available in a wide range of sizes and materials. Zinc/alum and a full spectrum of pre-painted roofing colours are available, including stainless steel and aluminium on special request. Rainheads, as well as being decorative, minimise the risk of water overflow inside a building, however Stratco recommends all rainheads be fitted with overflows. Size and shape should be determined at time of ordering.
Standard Rainhead Sizes
When determining the size of your rainhead you will need to consider such things as rainfall intensity, occurrence, use of the building and the size of the box gutter. This is best done by your architect, engineer or building designer and should conform to the requirements of AS/NZS 3500.3:2003 Plumbing and Drainage.

Ordering Your Rainhead
When ordering a rainhead you must specify the dimensions of the design. You will need to know the length, width and height. Depending on the style you choose, you may also need to know the bead height. See below for three examples showing the dimensions you will require.
All rainheads include a fitted downpipe outlet which is available in a wide range of sizes. When ordering your Stratco Rainhead it is important that you specify the size and position of the downpipe outlet. An overflow provision is also included on all standard Stratco rainheads. The size and position of the overflow needs to be specified when your rainhead order is placed. Overflow spouts are available as optional extras, in round, square or rectangular shapes.
