Full Automatic Half Round Rainwater Gutter Roll Forming Machine

A PLC-controlled roll forming line that produces half-round rainwater gutter profiles from PPGI or GI steel coil. The coil is progressively formed through 12 stations, cut by a hydraulic cutter and discharged as a finished gutter profile, with a production capacity of 0-20 m/min.

• Production capacity of 0-20 m/min.
• 12 forming stations for the half-round gutter profile.
• 80 mm shafts carrying 45# steel rollers with surface hard chromium plating.
• Forms PPGI / GI steel from 0.5 mm to 1.2 mm thick.
• PLC control system with hydraulic cutting.
• 350 H steel welded machine frame, motor for roll forming 5.5 kW.

Product Overview

This is a dedicated gutter and downspout roll forming line for the metal roofing industry. It turns colour-coated steel coil into half-round rainwater gutter sections, which are used along roof edges to collect and carry rainwater into the downspout system. The line is supplied as a complete set: the roll forming main body, the electrical control cabinet and the hydraulic pump station.

Because the profile is formed in a single continuous pass, the machine suits roofing sheet producers and metal building material factories that need a steady, repeatable supply of gutter profiles in the same finish as their roof panels.

Key Features

12-Station Half-Round Forming

The gutter profile is shaped progressively through 12 roller stations, so the half-round section is built up in steps rather than in a single bend, which keeps the section consistent along the coil.

Roller and Shaft Construction

Rollers are made of 45# steel with surface hard chromium plating and are carried on 80 mm shafts, mounted in the machine side frames.

350 H Steel Welded Frame

The machine frame is built from 350 H steel in a welded structure, giving the forming line a rigid base along its full length.

PLC Control and Hydraulic Cutting

An imported-brand PLC manages the line, and the formed profile is separated by hydraulic cutting at the end of the forming section.

Material Range

The line forms PPGI and GI steel with a rolling thickness of 0.5 mm to 1.2 mm. The machine colour is produced as required for the order.

Customization and Support

Tile type, name plate, voltage and production capacity can be specified per order, with drawing-based, sample-based and full customization available. Free replacement parts and online technical support are provided.

Machine Structure

The forming unit carries the roller stations in blue upright frames along a welded base. Each station holds an upper and a lower roller on 80 mm shafts, and the threaded rods on top of the frames are used to set the roller gap for the coil thickness being run.

Applications

The machine produces half-round gutter profiles for roof rainwater drainage in gutter and downspout systems: villa and residential roofs, workshop and warehouse buildings, and colour-coated steel roofing projects. It is normally installed in a roll forming workshop next to the roofing sheet line, so the gutter profile is made in the same production cycle as the roof panel.

Finished Gutter Profile

The line delivers finished half-round gutter sections straight off the cutting unit. Length is cut as set, and the profiles can be produced in the coating colour matched to the roof system, as the machine colour and tile type are made to order.
