FAQ
Do I need two mills for gutter and downpipe?
This example is a paired package: gutter mill, downpipe mill, plus a bend / neck unit. A square downpipe mill on its own is a different quotation.
Where do 312 mm and 22 stands come from?
From the quotation that matches that delivered paired package. Square 3 x 3 in uses its own file.
Is this the same as a metal roofing line?
Roof sheets belong on the roofing solution. This page is rainwater goods.
How are price and lead time quoted?
Send the quote checklist. Commercial terms come back on the offer.
