Trapezoidal Panel Roll Forming Machine Factory

What is trapezoidal roof profile?

A trapezoidal roof profiles have ribbed trapezoidal-shape patterns across the panel. This means, it is a quadrilateral (or a four-sided shape) that has just a single pair of parallel sides. Sometimes trapezoidal roofs are mistakenly called corrugated profile. This is a misnomer because the ripple profile has a repeating wavy pattern on its entire surface. Trapezoidal ribbed roofs are popular among producers because of their shape giving them high material efficiency (high strength-to-weight ratio). This makes it very cost effective. Whether mounted vertically, diagonally or horizontally, trapezoidal shadows provide clear lines. They also have good structural characteristics and can withstand design loads well (for example, snow and wind bulges). However, due to its attachment method, the contour cannot be considered as an upright seam.

Generally, trapezoidal roofs are fixed on the surface or straight through (that is, barely fixed), which means that the panel is fixed in place by fasteners that pierce the material with washer screws fixed in the structure. The rib spacing varies from 6 inches to 12 inches, and there may be tiny "second ribs" between them, which helps to stiffen the panel. Although they usually look the same at first glance, the exact size and angle vary from manufacturer to manufacturer. Trapezoidal rib roofs are popular all over the world and are cheaper than traditional standing seam roof profiles. In fact, there are standing seam profiles that also borrow the benefits of the trapezoidal shape. And they are the industry standard for large buildings due to the cost-effectiveness of trapezoidal rib geometries.

 

There is a good analogy to explain the good structural characteristics of trapezoidal rib roof profiles. Consider the ancient pyramids. The pyramid shape is just a trapezoid with its top cut off. Pyramids have literally stood the test of time over thousands of years. The sturdy design of the pyramid proves that its shape facilitates load distribution, creating a more stable support structure.

The Usage of Trapezoida lprofiles

The trapezoidal profile is used for roof structures. They are used to build load-bearing roof shells in dry buildings. The number of supports required for construction in progress can be significantly reduced, as casing is no longer required for new concrete. The trapezoidal profile is increasingly used as an additional roof in the construction of modern multi-storey parking lots. In this application, the trapezoidal profile is not only used as a shell in the building, but also forms an integral load-bearing part of the roof structure when completed. In this case, the carrying capacity of concrete and trapezoidal profiles has been used. Another well-known application area is composite floor. The special-shaped steel trapezoidal profile establishes a bond between the concrete and the steel, so the advantages of the materials used can be fully utilized. In these floor structures, concrete absorbs compressive forces, while composite floor profiles absorb tensile forces.

What is Trapezoidal Panel Roll Forming Machine?

It’s a machine can produce Trapezoidal Panel in cold roll forming process, normally the forming is starting from the middle to both sides. The tools are designed according to the profile, so different profile requires a different roll forming machine. The machine can work on pre-painted panel, galvanized panel, aluminum panel.

The machine can continuously produce the Trapezoidal sheet from uncoiling to cutting and stacking.
