what is Trapezoidal roll forming machine

A Trapezoidal Roll Forming Machine is a specialized cold roll forming system designed to produce trapezoidal-profile metal panels for roofing and wall cladding applications. It is widely used in industrial, commercial, and residential construction projects.

The term “trapezoidal” refers to the cross-sectional shape of the finished panel, featuring ribs with straight or sloped sides and flat tops, creating a trapezoidal profile. Compared with traditional corrugated profiles, this geometry provides improved water-carrying capacity and greater spanning capability, making trapezoidal panels suitable for a wide range of roofing and wall cladding applications.

Trapezoidal Roof Sheet

A trapezoidal panel, also known as a trapezoidal profile, trapezoidal rib panel, or box profile panel, is a metal roofing and cladding panel featuring distinctive trapezoidal ribs with flat tops, sloped sides, and wide flat pans between the ribs.

Unlike corrugated panels, which feature a sinusoidal wave profile, trapezoidal panels have straight, angular ribs that provide high structural strength, load-bearing capacity, and spanning capability. This profile is widely used for both roofing and wall cladding applications.

Why Choose Our Trapezoidal Roll Forming Machine?

Heavy-Duty Machine Frame

Built with a 300H–350H welded steel frame and Ø75–Ø95 mm precision-ground shafts. The heavy-duty construction minimizes shaft deflection at high forming speeds, helping produce straight, distortion-free panels.

Automatic PLC Control System

Equipped with a Siemens or Delta PLC and touchscreen interface. A single operator can control panel length, quantity, and batch production settings. Cutting accuracy is up to ±1.5 mm.

High-Speed Hydraulic Tracking Cutting

The hydraulic tracking cutting system cuts panels while the machine is running, minimizing production interruptions. It delivers clean, burr-free edges and supports neat, consistent panel stacking.

Wide Profile Range

One machine can produce multiple trapezoidal profiles by changing the roller tooling set, from shallow 15 mm wall panels to deep 75 mm structural panels.

Global Voltage Compatibility

Power configurations can be customized to local electrical standards, including 380V/50Hz, 480V/60Hz, 220V/60Hz, and 415V/50Hz, for easier installation and commissioning.

Direct Factory Support

We are the manufacturer, providing direct factory pricing, quality control, and technical support without intermediaries. Customers receive direct assistance from our engineering and after-sales teams.

Complete Production Line Solution

Complete solutions are available from decoiling and roll forming to cutting and stacking. Each machine can be test-run before shipment, with a test video provided for reference. Spare parts lists and technical documentation are also included.

FAQ

What profiles can your machine produce?

Any trapezoidal profile. Tell us your required rib height (15–75mm), pitch (100–300mm), and effective coverage (600–1200mm). We design rollers accordingly.

Can the same machine produce multiple trapezoidal profiles?

Yes – by changing the roller set. We can also supply a double‑layer machine to produce two different profiles without changing rollers.

What thickness can the machine handle?

Standard: 0.3–1.0mm. Heavy‑duty version: up to 1.2mm.
