LYSAGHT® Half Round Gutter and
LYSAGHT® Flat Back Gutter

Product Description and Features

The LYSAGHT® Half Round and LYSAGHT® Flat Back style gutters have been designed with a unique curved base which can prevent build-up of water and dirt, allowing the gutter to clean itself with every shower of rain.

• LYSAGHT® Half Round gutter is available with external brackets only
• LYSAGHT® Flat Back gutter uses internal brackets only
• Large water carrying capacity gutter with overflow slots in the design, specifically for the tropics. Available unslotted on request
• Range of easy fix accessories and brackets, makes installation easier

Note:

• Styles and dimensions vary for each state, see availability tables
• It is important gutters slope towards the outlets (a minimum gutter fall of 1 in 500 is recommended). Without this slope, 'ponding' may occur, reducing the life of your gutter
• When installing gutters, remove any metal particles or debris at the end of the day to prevent staining or corrosion
• Do not install galvanised gutters with a ZINCALUME® steel or COLORBOND® prepainted steel roof. Galvanised gutters are only suitable with galvanised steel roof
• The protective plastic film should be stripped off immediately on installation
• Read our Guidelines for using COLORBOND® steel & ZINCALUME® steel.

Designing Roof Drainage

Correct design of a roof drainage system is critical to the waterproofing of a building. This is a task that should only be carried out by a suitably qualified trade professional in accordance with the BCA and Australian Standards.

In the design and detailing of a roof drainage system, consideration must be given to a range of factors such as:

• rainfall intensity
• roof catchment area
• gutter size/capacity
• gutter fall
• gutter outlets (sumps, rain heads, nozzles)
• downpipe size, quantity and placement
• overflow consideration
• material selection and
• jointing
