The core material for your panels depends on the building requirements and budget. For Z lock roofing and wall panels, EPS is a common, economical choice. However, the same production line can often process XPS board, Rockwool, or Glass mineral wool as alternative insulation cores. The specific material you choose will affect panel performance, fire resistance, and insulation values. MTC can help you configure the line for the core material that best suits your application and local building codes.

The production line is designed to work with pre-painted steel coils. Based on the page’s description of roofing panels, the line can handle metal skins from 0.3mm to 0.8mm thick, with a maximum coil width of 1250mm. For wall panels, the same thickness range typically applies, but the width may differ based on the panel profile. Your specific coil dimensions will depend on the panel design and whether you are producing roofing or wall panels.

This line is specifically intended for Z lock profiles, which are commonly used for both roofing and wall panels in standing seam and concealed fastener systems. For roofing sandwich panels, the outer skin will be formed as a trapezoidal roofing sheet. The line can be equipped with a double layer roll forming machine when you need to produce two different roof panel profiles. The exact profile dimensions, including rib height and spacing, are configured based on your project’s structural and aesthetic requirements.

A complete line typically includes three manual uncoilers (decoilers) for the top and bottom metal sheets, plus a roll forming machine for the roof or wall panel profile. For mixed production, a double layer roll former can be used. The line also has a feeding table for the insulation core, a glue mixing and application system, a continuous pressing or composing section, a tracking fly-saw cutter for cutting panels to length, and a run-out table for finished panels. Optional accessories like automatic stacking and packing systems are available upon request.

Panels are cut to length using a tracking fly-saw cutter that moves with the panel as it is produced. This saw allows for continuous processing without stopping the line. You can program the control system to produce panels in various lengths as needed for your projects. The accuracy of the cutting system ensures that each panel has clean, square ends, which is essential for correct Z lock joint fit-up during installation. Exact cutting tolerances should be confirmed with MTC based on your specific production needs.

A single-layer roll forming machine is suited to producing one specific profile. A double-layer machine is recommended when you need to produce two different types of roof panels—such as both roofing and wall profiles, or two different roof profiles—on the same line. This setup saves floor space and reduces equipment cost compared to buying two separate lines. The decision depends on the variety of panel profiles your customers require. For a Z lock roofing and wall range, a double-layer machine is often practical.

When visiting a manufacturer like MTC, focus on the actual build quality of the machine, the control system’s ease of use, and the backup support services. Ask about the installation and training process, as well as the availability of spare parts. You should also inspect a running production line at a local customer’s facility, as the client in this article did, to see the real output quality and operational reliability. Review the sales contract carefully to ensure clear aftersales service commitments are included.
