Cold Roll Forming
Machine Manufacturer

A roll forming machine is a production line that shapes metal coil into a fixed cross-section by passing it through a series of rollers, each bending the strip a little further until the profile is closed, then cutting it to length. Because the profile comes off the line in continuous runs, roll forming is how long, consistent metal sections are made in volume — roof sheets, purlins, framing, decking and channel. The knowledge base walks through the process step by step.

Nine product groups cover 41 machine types: roofing and wall cladding, light steel framing and purlins, floor decking, solar mounting and cable tray, guardrail and barrier, sandwich panel and embossing, door frames and roller shutter slats, rainwater goods and drainage channel, plus coil handling equipment. Browse the full range or start from the application you sell into.

PPGI, PPGL, GI and GL coil, galvanised and cold-rolled carbon steel, and — depending on the profile — stainless 304 and aluminium. Thickness follows the product rather than the machine: light cladding runs in thin sheet, structural sections run in heavier strip, and across the range we cover 0.2–4.0 mm. Send us the section and we will confirm the exact range the tooling is cut for.

Yes — a custom profile is the normal case, not the exception. The line is built around your profile drawing: the roller set is designed and cut for your section, the punching pattern and cut-length control are programmed for your product, and speed and auxiliary equipment are matched to your output target. If you sell into more than one market, interchangeable cassettes let one machine cover several profiles.

The line is assembled and run at our works before shipment, and the forming and leveling settings are commissioned on your coil section — that is where you see the machine produce the profile rather than being told it will. Factory running video is available for the major machine types, so you can check actual line speed and profile output before ordering.

One set. Every line is manufactured to order around the profile it will produce, so there is no batch minimum. The real constraint is that the tooling is cut for one section — which is why the ordering stage is where the section gets settled, and why sending us the drawing early matters more than volume.

It depends on the line. Across the current range, quoted production runs from about 25 days for a standalone decoiler to around 120 days for a complete coil slitting line, with most forming lines between 35 and 65 days. Each machine page carries its own lead time, and the figure is confirmed in your quotation.

Settle the front end at the same time as the machine. A matched decoiler — 3 T, 5 T or 10 T, sized to the coil you can actually buy — plus a leveling unit if your coil arrives with retained set or edge damage, and a runout table so the profile is supported as it leaves the line. Buying them as one line means speed and tension are matched, and there is a single point of responsibility. See auxiliary equipment.

Installation and commissioning, operator training and after-sales technical support are part of the order, and the terms — including how many engineer days are included — are set out in your contract. Operators are trained on the installed machine with your own material, because the settings that matter are the ones specific to your profile. Read what after-sales covers.

Send the profile drawing or a sample section, the material and thickness, the coil weight you buy, the output you need and your power supply. With those, a quotation is a machine specification rather than a price. Tel / WhatsApp +86 131 6656 7923, or use the contact form. Prices are quoted FOB Tianjin.
