Exterior panel for construction and manufacturing method thereof and sandwich panel using the exterior panel

摘要

The present invention relates to an exterior panel for building, a method of manufacturing the same, and a sandwich panel using the exterior panel, and a straight horizontal stripe 13 compression-molded to the front or rear of the panel in the width direction of the exterior panel 10 is formed. . The strength of the exterior panel 10 is improved, so that when the coupling portion (the coupling protrusion 11 and the coupling groove 12) is formed on the panel, the formation of the bent portion due to the oil canning phenomenon is prevented, so that the appearance of the bent portion is prevented from deteriorating. The sandwich panel manufactured using the exterior panel 10 also has the same effect due to horizontal stripes.
