Trapezoidal IRB Roof Sheet Machine - 26 Stations

Every roofing contractor and building-material distributor needs a line that turns coil into sale-ready panels at a predictable cost. This Trapezoidal IRB Roof Sheet is built around that job: it forms the target profile continuously, cuts it to a programmable length, and keeps sheet dimensions consistent so panels pack, stack and install without rework.

Overview

The Trapezoidal IRB Roof Sheet Machine is a fully automatic roll forming line designed to produce trapezoidal and IRB roof sheet profiles with 26 forming stations. With 0.3-0.8 mm material, feeding width Other, 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 BV STV ISO certified with a 2 years warranty. Every unit ships with a machinery test report and video outgoing-inspection.

Roofing lines of this class are used across residential and light-commercial projects: house roofs, farm buildings, warehouses, workshops and shade structures. Buyers in Africa, the Middle East, Southeast Asia and Latin America run these machines to produce corrugated and trapezoidal sheet, ridge capping, flashings and trim sold through local hardware channels.

Key Specifications of the Trapezoidal IRB Roof Sheet

The profile is formed progressively through 26 stations, which spreads the bending load over many passes and keeps section dimensions steady across long runs. The line is set up for coil in the 0.3-0.8 mm thickness range, with roller clearances and cutting capacity matched to that material program. Electrical supply is 220V-3P-50HZ, and the control cabinet can be adapted to your local voltage when ordering. Length presets, counting and profile programs run on the Add Customer Request Language, so operators switch between jobs from the panel without mechanical re-setup. Forming rollers are Gcr12 Steel, 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.

Three things decide whether a roofing line earns back its cost: changeover speed, cut accuracy and roller life. This Trapezoidal IRB Roof Sheet addresses each directly. Profile changes take minutes because the roller stations sit on a common frame; the PLC stores multiple length presets so operators switch between panel lengths in seconds; and the rollers are machined from hardened, ground steel that keeps width consistent across tens of thousands of meters.

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.

How many forming stations does this machine have?

This model is equipped with 26 stations. The station count is matched to the profile complexity, so each pass adds only a small bend and the section holds its shape without spring-back issues.

What material thickness can this machine process?

The machine is configured for coil thickness in the 0.3-0.8 mm range. If you plan to run material outside this range, tell us in advance so we can adjust the roller stations and cutting unit.

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.

How is the machine tested before shipping?

We run a full production test with your coil width and gauge, cut sample sheets, and record the profiles and lengths. You receive test photos and video before shipment.

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.

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.
