Trapezoidal Roofing Line Solution (TR4)
Coil-to-panel TR4 roof line for metal buildings. Host + 5 T decoiler; curving, ridge and gutter as options. Start with the first-year profile.
Who it's for
Who it's for Sheet processors and metal-building plants whose first-year tonnage is trapezoidal roof panel — especially TR4 in Latin America. Typical questions ● Which profile first — lock TR4 before buying a second roll set (TR5) or a dual-layer host. ● Electrics — 220/380/440 V 60 Hz are all used in LATAM; HMI must include Spanish. ● Coil — PPGI/PPGL 0.3–0.6 mm, 1200/1220 mm class. ● What to add later — curving, ridge, gutter. Leave floor space on day one.

How to choose a line
- First-year tonnage is trapezoidal / IBR -> Trapezoidal / IBR main line (General panel host if the tooling family is still open)
- Standing-seam roof is the main product -> Standing-seam line (Curving and seam lock are optional units)
- Corrugated / arc volume first -> Corrugated / arc line (Often with a curve module)
- Glazed tile as a second SKU -> Glazed-tile line (own tooling) (Peak-height variants stay on their own quotations)
- Horizontal cladding, KR700 wall, or market-specific C-series -> Matching wall / cladding line (Quoted apart from standing-seam roof)
Example specification
One delivered example. Final numbers follow your quotation.

What's included
First-year roof/wall panel host, process spine, equipment matching, a parameter checklist, and a quote list. Speeds and kW come from the quotation for that profile.
What to send for a quote
- Profile drawings for the first-year main product
- Year-one mix across trapezoid / standing seam / corrugated / glaze
- Coil family, thickness window, width, coating
- Destination electrics and HMI language
- Which optionals belong in the first order vs later (stacker, curving, seam lock, ridge/trim)
- Market-specific wall or C-series profiles called out if needed
Check before you quote
One speed for every profile
One speed for every profile
Trapezoid, standing seam and glazed tile each use their own quotation for kW and m/min.

Different peak-height tile families stay on separate tooling quotes.

Curving and ridge
Treat curving, seam lock and ridge as optionals unless the offer includes them. Leave layout length for them.
FAQ
Customer wants TR4 and TR5?
Two hosts, two quotes. A shared decoiler can be discussed. Not one TR4-S machine.
Must curving come from the same factory?
Not mandatory. Same-factory debug is easier; we quote them together.
Can ridge be bought later?
Yes.
