Trapezoidal Roof Sheet Curving & Crimping Machine

Sheet demand changes fast, and a fixed-profile press locks you into one product. This Trapezoidal Roof Sheet Curving & Crimping gives you the flexibility to run different roofing profile orders without retooling delays. Hardened forming rollers, a PLC length control system and a square-cutting shear keep every sheet within the same tolerance, order after order.

Overview

The Trapezoidal Roof Sheet Curving & Crimping Machine is a fully automatic roll forming line designed to produce trapezoidal roofing sheet profiles with curving and crimping. With 0.3-1mm material, feeding width 1250 mm, it delivers consistent, high quality production for building and construction applications.

Manufactured by Zhongtuo (ZTRFM) in Botou, Hebei, China, this machine uses high grade 45# steel shafts and rollers. PLC control ensures automatic operation. It is CE ISO certified with a 2 Years warranty. Every unit ships with a machinery test report and video outgoing-inspection.

The profiles this machine produces are also the base material for roofing accessories such as end caps, flashings and trim sections. Adding this profile to an existing workshop lets you serve one project with several products instead of buying each from a different supplier, which shortens customer lead times and raises average order value.

Key Specifications of the Trapezoidal Roof Sheet Curving & Crimping

The line is set up for coil in the 0.3-1mm thickness range, with roller clearances and cutting capacity matched to that material program. Feeding width is 1250 mm, which determines the widest profile this machine can produce and the coil sizes you can buy economically. Electrical supply is 380v/50hz/3p (As Requested), and the control cabinet can be adapted to your local voltage when ordering. Length presets, counting and profile programs run on the PLC(imported Brand), so operators switch between jobs from the panel without mechanical re-setup. Forming rollers are 45#steel Chrome Plated, giving predictable profile accuracy and long intervals between re-grinds. The forming shafts are High Grade No.45 Forged, selected for stiffness so the roller stack stays aligned under load.

Before delivery we run a full production test with your coil width and gauge, record the sample profiles, and send you photos and video of the test run. Roller spares for the most common sizes are kept in stock, so routine wear does not stop production.

FAQ

What is the minimum order quantity?

The MOQ is 1 set.

What material does this machine process?

It processes PPGI PPGL GI GL coil.

What is the warranty period?

A 2 Years warranty applies, with machinery test report and video outgoing-inspection provided.

Can the machine be customized for my profile?

Yes. Roller sets and profiles can be customized to your drawings, and OEM/ODM service is available.

What material thickness can this machine process?

The machine is configured for coil thickness in the 0.3-1mm range. If you plan to run material outside this range, tell us in advance so we can adjust the roller stations and cutting unit.

What feeding width does this machine accept?

The feeding width is 1250 mm. This decides the maximum profile width and also the master coil widths you can purchase, which affects your material cost per meter.

How long does a profile change take?

Profile changes are measured in minutes, not hours, because the roller stations are mounted on a common frame and aligned to fixed centers. The PLC also stores the programs for your most common profiles, so after the changeover the operator only recalls the saved program.

What is the production speed?

Rated forming speed depends on the profile and material thickness. Typical roofing lines in this class run between 15 and 40 m/min for light profiles; we state the tested speed for your configuration in the quotation, based on a real test run with your coil.

Can the machine cut different sheet lengths automatically?

Yes. The PLC stores multiple length presets and the cutting system works at line speed. Operators select the programmed length, and the counter stops the line automatically after the set number of sheets.

Do you provide the rollers for my profile?

Yes. Every machine ships with the forming rollers, cutting tooling and PLC program matched to your profile drawing. If you add a new profile later, we can supply an additional roller set built to your drawing.
