Expanded sheet

Expanded sheet, as a unique metal decorative mesh, is highly favored in the modern decoration field. It is usually made of metal sheets such as carbon steel, galvanized steel, aluminum, copper, or stainless steel. Through a special process, a row of cutting tools on an industrial die-cutting machine cuts the metal sheet. During the cutting process, the tools push down the newly cut parts and stretch them to form "strips". These "strips" are connected with the uncut parts to form diamond-shaped mesh holes, thus presenting a regular diamond-shaped opening pattern. This unique structure not only reduces its own weight and cost but also achieves the function of ventilation and air permeability. Its surface can be subjected to special treatments such as gold plating, silver plating, titanium plating, and tin plating, presenting a variety of colors. It has a rich variety of types, including the standard type, which can be used for making storage cabinets, warehouse enclosures, etc.; the raised type, whose staggered ridges form a diamond pattern with the overlapping metal strips, which is conducive to air circulation; and the flat type, which is about 5% lighter than the standard type, with a smooth surface. After cold rolling treatment, its anti-skid coating makes it suitable for building walkways and stairs, and it is also commonly used in scenarios such as enclosures, decoration, and ventilation. Expanded sheet is widely used in areas such as building facade decoration, indoor and outdoor partitions, stair and balcony railing protection, window safety protection, and air vents, adding unique decorative effects and practical functions to the space.
