Company Introduction

Hengda is a full service manufacturer of sheet metal via processing of perforating, also expanded metal and fabricated perforated metal products for various uses. Perforated metal is a kind of sheet metal usually made with styles of perforating, embossing, slotting or checkered plates. The process of creating perforations is called perforating, which involves puncturing the workpiece (usually a thin metal sheet) with a tool. Slotted perforated metal is a sheet or coil of material made from metal that contains holes punched by a die. Embossing is a metal forming process for producing raised or sunken designs or relief in sheet material. Checkered plate, also known as Diamond plate, is a type of light-weight metal sheet with a regular pattern of raised diamonds or lines. We provide our customers with perforated metal sheets following specifications below: MaterialWe can provide the following materials for perforating:Stainless Steel, Galvanized Steel, Carbon Steel, Aluminum, and all types of metals.  SpecificationWe can manufacture a wide rang of metal sheets with thickness verifying from 0.35mm to 3 mm and width maximum 1200mm. Length is the overall measurement of the long side of the sheet. Width is the overall measurement of the -short side of the sheet. The standard sheet size is 1000mm*2000mm. and 1000mm*2500mm. The coil width 1000mm is also available. We also can process the special product for your requirement.  The hole shape for perforated metal products:Round, square, long round, triangle, scale, diamond, oval, hexangular, slot etc. Sheet Metal ApertureIn general it is advisable to use a hole size larger than the material thickness. The closer the hole size and material thickness come to a 1 to 1 ratio, the more difficult and expensive the process is. Dependent on the material type, smaller hole size to material ratios can be achieved. The minimum diameter we can fabricate is 0.8mm to 4 mm thickness . If you require a die that isn't already in our die bank, our experienced tool and die makers can quickly make exactly what you need at a reasonable cost.  http://www.perforated-metal.net
