Outdoor metal billboards and roadsigns are mainly made of galvanized sheet, stainless steel and aluminum alloy materials, which have rich diversity in material types and sizes and shapes, which also makes the processing of products more difficult. Traditional stamping technology can not meet the needs of product diversification and short proofing cycle due to long die replacement cycle and high cost.

With extreme high energy density, laser welding can process metal plates of different materials and thicknesses, and is not limited by graphics, without mold opening, which greatly shortens the proofing cycle, reduces the proofing cost, reduces the production cost of a single product, and is an ideal processing technology for the billboard industry.
