About Guttering Now
We offer a wide range of downpipes to suit a variety of applications.
Downpipes are manufactured in two standard sizes 100 x 50mm
and 100 x 75mm and come in 2400mm length.
Our wide range of square, rectangular and circular down pipes
are available in ZINCALUME® steel and a wide range of COLORBOND®
steel colours. These down pipes are designed for greater durability,
longer life and compatibility with steel and tile roofs.
They are manufactured from light, strong, high tensile steel
and fast and easy to install. These complement the wide range
of Metroll gutter, fascia, roofing and walling profiles.
