Roll Forming Machine Manufacturer

We build the rolls, the frames and the control cabinets — cold roll forming lines for roofing, framing, solar mounting, guardrail, floor deck and sandwich panel, made in Botou, Hebei, and shipped from Tianjin.

ZTRFM is the export brand of Cangzhou Zhongtuo Cold Roll Forming Machinery Co., Ltd., founded in 2019 in Botou, Hebei. The factory is 35,172 m² with 10 production lines and a published capacity of 300 sets per year across 33 machine types.

The reason this page exists separately from the rest of the site is that a buyer searching for a manufacturer is asking a different question from a buyer searching for a machine. The machine pages answer what a line can produce. This page answers whether the company behind it can actually build, test and commission it — which is decided by where the rolls are cut, who holds the certificate, and what happens on the day the line arrives.

Nine product families, one factory

Cold roll forming is one process applied to many sections. The difference between the families below is the tooling, the station count and the drive — not the plant they are built in.

Product family	Machine pages	What it covers
Metal Roofing	13	Trapezoidal, IBR, standing seam, glazed tile, corrugated and ridge cap lines.
Light Steel Framing	8	Stud and track, CZ and sigma purlin, ceiling T-bar, wall angle bead and AISI framing lines.
Solar Mounting	4	Omega rail, strut channel, NEMA cable tray and cable tray lines.
Auxiliary & Coil Handling	4	Decoilers, levelling, slitting and truss purlin equipment that feeds the main line.
Guardrail & Barrier	4	W-beam and ASTM M180 guardrail, fence panel and scaffold plank lines.
Door & Shutter	2	Roller shutter slat and steel door frame lines.
Drainage	2	K-style gutter and downpipe lines.
Floor Deck	2	Composite and ribbed floor deck lines.
Sandwich Panel	2	Sandwich panel production lines and metal embossing.

The certificate numbers matter more than the word “certified”. A CE declaration is issued against a machine model, so a certificate held for a roofing line does not cover a framing line. Ask for the number that matches the model being quoted, and check it against the machine in front of you.

What to ask any roll forming machine manufacturer

These five questions separate a factory from a reseller, and each one has an answer that can be checked rather than believed.

Can they show the machine running on their own floor, not a customer site?

A video from a customer plant proves the machine exists somewhere. A video from the manufacturer’s own workshop proves they can build, assemble and test it — and lets you see whether the frame, the stations and the electrical cabinet are made in-house or bought in. Ask for a live video call, not a file.

Which parts of the machine do they make themselves?

Roll forming is decided by the rolls and the frame. A manufacturer who cuts and hardens rolls in-house controls the profile tolerance; one who buys roll sets controls only assembly. Ask which operations happen on site and which are subcontracted, and expect a straight answer per operation.

How is the profile checked before shipment, and what do you receive as proof?

The measurable proof is a profile drawing with tolerance, plus a formed sample measured against it. Ask what the dimensional check covers — cover width, rib height, rib pitch, squareness of cut — and whether the report travels with the machine.

What is the certificate actually for?

A CE declaration names the machine model and a certificate number. Ask for the number and check that it matches the line you are buying, because a certificate issued for a roofing line does not cover a framing line. The certificate numbers are printed on this page for exactly that reason.

Who commissions the line, and what happens on day one of production?

Installation and commissioning is where most delays appear. Ask how many technician-days are included, whether the commissioning engineer is the manufacturer’s own employee, and what the buyer has to prepare — foundation, power, compressed air — before the team arrives.

Questions buyers ask before a factory visit

Is ZTRFM a manufacturer or a trading company?

ZTRFM is the export brand of Cangzhou Zhongtuo Cold Roll Forming Machinery Co., Ltd., a manufacturer founded in 2019 in Botou, Hebei, China, with a 35,172 m² factory, 100+ staff and 10 production lines. Rolls, frames and electrical cabinets are built and assembled on site, and machines are run before shipment.

What is the factory capacity?

The published capacity is 300 sets per year across 10 production lines, covering 33 machine types. Lead time is quoted per machine because it depends on the profile, the number of stations and the control configuration rather than on a general schedule.

How many product families does the factory build?

Nine: metal roofing, light steel framing, solar mounting, guardrail and barrier, floor deck, sandwich panel, door and shutter, drainage, and auxiliary coil handling equipment. Those nine families hold 41 machine pages on this site.

What certifications can a buyer check?

CE Declarations of Conformity are held for a roofing sheet machine, a framing L angle machine, a C stud and joiner machine and a gutter profile machine. The company also holds High-Tech Enterprise status (GR202413001735, valid to November 2027) and Hebei Specialized & Innovative SME status (valid to August 2028), and is an SGS-verified exporter.

Can a machine be built to a profile the buyer supplies?

Yes. Profile drawings, a formed sample or a specified section drawing are all workable starting points, and the tooling is cut to that section. What has to be fixed before rolls are cut is the material thickness range, the yield strength and the coil width, because those set the station count and the drive power.

How do I verify the factory before paying a deposit?

Ask for a live video walk-through of the workshop rather than a recorded file, request the CE certificate number for the exact model being quoted, and ask which operations are done in-house. All three are answerable in a single call, and any hesitation on the certificate number is worth treating as an answer in itself.

Talk to the factory

Send the profile you need to produce, the material thickness range and your target output, and the reply comes back as a specification rather than a brochure.
