Metal Safety Steel Gratings, Perforated Metal

   Perforated metal specification

   1. Plate selection
    When select the plate, make sure that take both application requirement and product cost into consideration.

    If you’d like to reduce the thickness of plate, you’d better use the alloy materials with slightly higher price.

    At the same time the hardness and strength of plate directly determines the sizes and arrangement of holes.

    We can supply the plate materials as follows: Stainless Steel plate, High or Low carbon Steel Plate,

    Galvanized Plate, Zinc Plate, Aluminum Plate, Aluminum Alloy Plate, Mg-Al Plate and Nickel Plate ,etc.
    2. Aperture
    In general it is advisable to use a hole size larger than the material thickness. That is, to meet the minimum

    aperture principle. The closer the hole size and material thickness,

    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.

    If you have the special need,we wil try best to meet your need with the most reasonable price and the most  

    quality products.
    3.Hole spacing
    Hole center is the distance from the center of one hole to the center of the nearest hole

    in the next adjoining row.

    Hole spacing is a way to indicate hole center, another way is opening area.

    Both the significance of two methods is the same. You only need to determine either of both.
    4.Plate specification
    The thin plate is easier to perforate and the price is relatively low. According to the principle of minimum  

    diameter,

    the suitable thickness is more conductive to increasing the compressive strength. In general,

    the plate has the tolerance,

    we can manufacture a wide rang of thick sheet verifying from 0.1mm to 2.5 mm thickness Sheet 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. The coil width 1000mm is also available.

    We also can process the special product for your requirement if you tell us the exact specification.
    5.Opening area
    Clearly, open area is the total area of the holes divided by the total area of the sheet and is expressed as a percent ,

    Keep in mind that punching holes in a material add stresses that can result in distortion of the product.

    The higher the open area, the more material distortion takes place,

    especially when the perforated pattern is bordered by margins on all four sides.

    But these distortions can be removed by our special in house leveling process.

    Therefore, the flatness request of products wlill be sent after you take careful consideration in it.
    6.Margins
    Margins are the blank area along the edges of the sheet. In general, the long sides of plate need the margins,

    and the short sides not. If you want the product with special margins,you should provide the width of each margin

    on all four sides (measured from the edge of the sheet to the edge of the first hole).

    Manufacturing considerations may affect margins. If the margins requested are not possible.

    We will replace it with the similar products as your consideration.
    7.Tolerance
    There are tolerances on thickness, pitch, openings, flatness, and shearing for perforated products.

    It is the same as other production process, The higher the request about tolerance,

    the price of the products will be  higher relatively.

    You should specify a specific tolerance, so we can give you a precise product.

    If not, we will according to standard tolerance.

   Anti-skid stair treads specification

    (Both Electro galvanized and Hot Dipped galvanized surface treatment are available for low carbon steel material)

    Features: anti-skid, anti-rust and anti-corrosion, durable and sturdy application shows beautiful appearance.

    Application: used well for sewage treatment, for running water and power plant, also used for outdoor of many other lines,

    such as safety grating for vehicles, steppes for train, safety stair treads for machines and for interior decoration 

  Mold

  Piercing process began in precision mold design,

  we believe that mold to a large extent determine the quality of the product quality.

  Therefore, in recent years we have devoted considerable resources

  to make our modeling capability has been noticeably improved.
  Piercing
  We have advanced CNC equipment, the system can-quality products, output could reach 2,000²,

  the system can-sheet thickness between 0.1mm – 2.5mm.
  Cutting
  The entire volume from the plate cut into the size you need.
  Cutting Edge
  If the plate-making process beyond the scope of your request tolerance,

  we skilled technical personnel at your request can help you remove redundant Edge.
  Leveling
  We can use the school-to-machine system before punching deformation of the plate

  to restore its original state formation. 0.8mm-12mm thickness of the plate can be a full-ping.
  Clean
  Piercing processes require the use of lubricant,

  but we also have a degreasing process can remove traces of its surface, Orifice is clean.
  The production and processing of molding
  Apart from the subscription, we can offer you that the series of follow-up processing,

  including: leveling, cutting, labeling, packaging, degreasing, to thorn in shape, annealing, painting,

  electroplating, welding, grinding,  bending, such as volume.
  Surface Treatment

  Punch, the whole peace process would lead to cutting and sheet metal surface incomplete,

  but these incomplete in the general industrial supplies can be accepted.

  If you have special requirements, we will, for example through powder spray or spray paint,

  electric galvanized, hot-dip galvanizing, anodizing and other additional measures to prevent.
  Package
  Perforated metal usually use the bulk form, we can use cloth, wood boxes, cartons

  according to your request. We can also use the wooden pallets or steel tray with the large quantity products.
  Transport
  We can transport the products with courier companies, railway express, courier, road, rail, aviation

  and other different transport ways.

  Hole patterns:

  alligator mouth, round hole, raised holes, etc.
  Material:

  Aluminum, Low carbon steel, Stainless Steel, we can customize as demand material and holes.
  Production technique:

  CNC punching--cutting and bending--welding--shape
  Plate thickness:

  1-3mm(as demands of customers)
  Features:

  Anti-skid, anti-rust and anti-corrosion, durable and sturdy application shows beautiful appearance.
  Applications:

  used well for sewage treatment, for running water and power plant, also used for

  outdoor of many other lines,

  such as safety grating for vehicles, steppes for train, safety stair treads for machines

  and for interior decoration
 

 Huijin anti-skid stair treads patterns improves and increase continuously,

 with higher and higher consciousness of people,

 even many factories offer injury insurance for the workers to avoid the loss that the accident injury brings,

 however, it is hard to stop the incident rates that workers injured.

 In this function, safety grating owns excellent anti skidding ability,

 also high load capability and great anti-pressure ability decrease the injury rates greatly

 and guarantee the safe running of the workshop.
