Downspout and Gutter Roll Forming Machine
A downspout and gutter roll forming machine turns painted coil into a finished rainwater system, one profile at a time. A K-style gutter, a half-round gutter, a box gutter and the downspout that drains it each need their own roll set, punch pattern and cutoff, so most drainage plants run two or three of these lines side by side.

How the line works
Coil in, hanger holes punched, gutter out
A downspout and gutter roll forming machine runs the same five steps as any light gauge line. The difference sits in the tooling: a gutter is wide and open, so the rolls have to hold the front lip and the bead without marking the paint.
01
Decoiler
A 1.5 to 3 t mandrel carries aluminum, galvanized or copper coil. A coil car keeps the overhead crane free.
02
Leveler and feeder
The leveler takes coil set out, then a servo feeder measures each gutter or pipe length before the shear.
03
Punching and notching
Hanger holes every 600 mm, outlet holes and end laps are punched through a die set before the profile closes.
04
Roll forming
14 to 24 driven stations on a downspout and gutter roll forming machine fold the pan, the front lip and the bead. A box gutter needs more passes than a K-style.
05
Cutoff and runout
A flying shear cuts on the move, so the line does not stop between lengths. Gutters leave on a 6 m runout table.
Profile families
Four sections one drainage plant rolls
Every quote for a downspout and gutter roll forming machine starts from the section drawing. These four cover most of the rainwater work we build for.
01 / K-style
K-style gutter
The North American residential profile, 5 in and 6 in, with a flat back, an OGEE front and a folded lip. Rolled from painted aluminum, galvanized or copper.
02 / Half-round
Half-round gutter
A true half circle in 100, 125 and 150 mm, the default for historic and high-end housing in Europe and Australia. Copper and aluminum are common.
03 / Box
Box and valley gutter
Square-sided gutters 200 to 600 mm wide for industrial roofs and valley runs. Heavier coil, more stations and a sealed corner.
04 / Pipe
Downspout and elbow
Rectangular 2x3 in and 3x4 in, or round 3 in and 4 in, corrugated or smooth. The elbow former bends offsets from the same strip.
Machine range
Four lines that build a rainwater system
A downspout and gutter roll forming machine is bought per section, so each page below carries the drawing, station count and output for one part of the system. All four share the same frame, drive and control platform.
01 / Gutter
Gutter Roll Forming Machine
K-style, half-round, fascia and European profiles on one frame, with Siemens PLC control and a flying shear for 6 m lengths.

02 / Downspout
Downspout Roll Forming Machine
Rectangular and round downpipes on a 70 mm shaft mill, with an elbow machine fitted at the end of the same line.
View the downspout line →
03 / Elbow
Downspout and Elbow Roll Former
A 21 step former that bends elbow offsets in seamless pieces, so a run changes direction without a joint.
View the elbow former →
04 / Portable
Portable Gutter Machine
The same K-style and half-round sections on a trailer, forming 0.3 to 0.5 mm coil at the job site instead of the factory.
View the portable machine →These lines sit under the roll forming machine range we build, and a plant that also rolls its own fascia, flashing or sheet can feed them from a metal sheet roll forming machine. A section that no standard line covers goes to our customized profile roll forming machine team instead.

Cost drivers
Four things that move the price
Two quotes for the same gutter can differ by a factor of two. These are the four choices that explain the gap, and the ones to settle before a downspout and gutter roll forming machine is ordered.
01
Profile family
On a downspout and gutter roll forming machine a K-style gutter forms in 14 stations, while a box gutter or an industrial valley needs 22 or more. Every extra stand is another pair of rolls, a shaft and a motor.
02
Material and thickness
Aluminum downspout at 1.2 mm needs a heavier shaft than 0.4 mm painted steel, and that choice drives the frame size of a downspout and gutter roll forming machine. Copper work adds chrome plating and a slower line speed to protect the surface.
03
Punch and notch tooling
Hanger holes, outlet cutouts and end laps run on one fixed die set per gutter size, or on a servo punch that changes position from the screen.
04
Length and handling
A 6 m runout table, an automatic stacker and a packing table add 15 to 30 percent and take one or two operators off the line.
Where these lines run
Four jobs that order a drainage line
The profile follows the building, not the machine. These four orders cover most of the work we quote, and each one fixes its own gutter size, hanger spacing and outlet position before a downspout and gutter roll forming machine is specified.
- Re-roofing and replacement guttersContractors running 5 in and 6 in K-style on painted aluminum, usually on a portable unit that forms to length at the house.
- New residential and commercial roofsA fixed downspout and gutter roll forming machine in the plant, feeding a fascia or half-round profile in copper or pre-painted steel for the whole development.
- Historic and high-end housingHalf-round copper gutters and round downspouts, where the surface finish matters as much as the section.
- Warehouses and industrial roofsBox and valley gutters 300 to 600 mm wide in 0.8 mm galvanized, cut in one piece for the full run.
Coil for a downspout and gutter roll forming machine is ordered to ASTM A653 or EN 10346, with the paint system chosen for the climate it will face.
Build and test
Every line runs before it ships
A downspout and gutter roll forming machine is judged on its bead and its lip as much as on the pan. Each line is assembled, wired and run in our works with the customer's coil, then measured against the section drawing before packing.
Flower pattern first
The pass design of a downspout and gutter roll forming machine is drawn before steel is cut. A gutter flower is checked for lip marks, springback and bead radius, because a painted surface shows every roll mark.
Trial run in our works
Every line runs at working speed with the customer's coil. Gutter length, hanger spacing and outlet position are measured on the first ten pieces.
Export packing
Rolls are greased and boxed, the shear and the control cabinet are wrapped, and a portable unit ships in one 20 ft container. A fixed line needs a 40 ft high cube.
Lines for the EU arrive with CE documentation under the EU CE marking rules, and UK orders are documented to UKCA through the GOV.UK UKCA guidance.
Questions
Downspout and gutter roll forming machine FAQ
What buyers ask before a drainage line is quoted, answered in plain terms.
What is a downspout and gutter roll forming machine?
A downspout and gutter roll forming machine is a line that folds coated coil into one part of a rainwater system, such as a K-style gutter, a half-round gutter, a box gutter or a downspout. It punches hanger and outlet holes inline, forms the section, then cuts each piece to length. A complete system needs a gutter line plus a downspout line, and often an elbow former.
Which gutter profiles can one line make?
One roll set covers one section family. A K-style line forms 5 in and 6 in OGEE gutters, a half-round line forms 100 to 150 mm half circles, and a box gutter needs its own tooling. Changeover between two sizes in the same family takes 30 to 90 minutes with spacers, or minutes on a line with motorized width adjustment.
What thickness and material can it run?
A portable downspout and gutter roll forming machine runs 0.3 to 0.5 mm painted aluminum or steel, a fixed gutter line 0.4 to 0.8 mm, and aluminum downspout 0.8 to 1.2 mm. Copper is rolled at 0.6 to 1.0 mm with chrome plated rolls and a slower line speed.
How are hanger holes and outlets made?
They are punched before the profile closes, either on a hydraulic press with a fixed die set or on a servo punch that moves between positions. Hanger holes usually sit at 600 mm centres, and the outlet is cut for a 2x3 in or 3x4 in pipe.
How fast does a gutter line run?
A fixed downspout and gutter roll forming machine runs 10 to 15 m/min. On a portable unit the forming speed is up to 10 m/min but the producing speed is 6 m/min, because the operator stops to shear and stack each length.
Can one machine make gutter and downspout?
No. A gutter section is wide and open, a downspout is a closed or lock seamed tube, and the two need different roll sets, shafts and cutoffs. A plant that runs a downspout and gutter roll forming machine for gutters buys a second line for downspouts, and shares the decoiler and the control platform between them.
How much does a line cost and how long is the lead time?
A portable K-style unit starts near USD 18,000. A fixed gutter line lands between USD 30,000 and 55,000, a downspout line between USD 28,000 and 45,000, and an elbow former adds USD 20,000 to 30,000. Build time is 30 to 55 days after the drawing and the deposit.
