The bend in 70 degrees is developed for a perfect fit to the nozzle piece. There’s no need for any fasteners or rivets to ensure the bend from falling down. The bend is conical with a big and small end, except for 50mm in each end that is straight for a perfect fit both to the nozzle piece and the intermediate pipe. The end with the label is always the small end that fits into the next product in the system. All products in the round downpipe assortment has this logic which makes the installation easier and faster, and the label is hidden. This product is made of precoated galvanized steel in 0,6mm thickness. Because of the high quality steel it will age in the same way as all the other products in the system and no difference in design will occur.
