Manufactured from SABS-quality galvanised steel of varying thickness depending on individual needs or architects specifications.
Round downpipes are manufactured in two sizes - 75mm diameter mainly for household applications and 100mm diameter for larger buildings where water displacement is essential.
Depending on the Shape of roof, the norm is one downpipe per every 3m of guttering - this will ensure sufficient drainage of the gutter to prevent it from overflowing.
To ensure a neat and durable installation, two holderbats per 2700mm downpipe should be used to fix the downpipe to the wall.
A choice of crimped or soldered downpipes are available, depending on aesthetic requirements and individual preference.
Protective Coating after Installation
A good quality acrylic PVA paint should be used to paint the galvanised material which will ensure a durable
stylish installation that will last many years.
