We configure the 840 Roofing Sheet Roll Forming Machine for roof and wall cladding panels that use the 840 mm coverage profile. The coil passes through the entry guide and 11 forming rows, then the PLC length setting and hydraulic guided cutter prepare the finished sheet.

Features
Profile Coverage
The 840 Roofing Sheet Roll Forming Machine produces the 840 mm effective-width sheet from 1000 mm feeding material.
01
Material Range
The listed line processes 0.25–0.8 mm galvanized color steel plate when the profile drawing is approved.
02
Forming Layou
11 forming rows, 70 mm shafts, and 300H frame support the profile during continuous forming.
03
Length Control
PLC, touch screen, and coding counter manage length and quantity before hydraulic guided shearing.
04
Coating Contact
Polished rollers and entry guides are checked to reduce direct rubbing on pre-painted material.
05
Applications
- Curved roofing for industrial buildings and warehouses
- Arch roof systems for stadiums and exhibition halls
- Integrated roofing and cladding for steel structures
- Agricultural and temporary structures requiring curved panels
Quality Control
Drawing Review: Confirm 840 mm effective width, 1000 mm feeding width, rib shape, overlap side, wave height, and cut length.
Material Trial: Run 0.25–0.8 mm galvanized color steel plate through the entry guide, 11 forming rows, and cutter.
Dimension Check: Measure effective width, rib spacing, panel length, side lap, and straightness on repeated sheets.
Surface Check: Inspect coating marks, roller pressure lines, edge scratches, and cutting burr after forming.
Control Check: Record PLC length input, coding counter response, hydraulic cutter timing, emergency stop, and batch count.
FAQ
Q: What material is required for the 840 Roofing Sheet Roll Forming Machine?
A: The listed specification uses galvanized color steel plate, 1000 mm feeding width, and 0.25–0.8 mm thickness.
Q: Can the profile be adjusted?
A: The roller set is made for the approved profile. Effective width, rib height, overlap, and cutting length must be confirmed before tooling.
Q: What is checked before delivery?
A: Check effective width, rib shape, panel length, side lap, surface condition, cut edge, PLC counting, and repeated forming at the agreed speed.
