Spiral Welded Anodized Perforated Steel Pipe For Automotive Engineering

Spiral Welded Anodized Perforated Steel Pipe For Automotive Engineering

Sheet sections are structural elements made of metal sheet with the C cross section. They are advantageous particularly for their shape stability, anti-slip properties guaranteed by a special surface structure, and trouble-free installation. Owing to their dimensional variability and large bearing lengths and the possibility of supplying to measure, the use of sheet sections will decrease the costs for a supporting structure. The use of sheet sections includes the constructions of working and inspection platforms and foot bridges of industrial equipment, as well as transport and supply.

• Sheet sections are made of coiled stock.
• After a successful input check, coiled stock is delivered to the manufacturing line. There a certain perforation is set out on the product surface using the appropriate tools and such perforated plank is then cut to length.
• When determining the length, the provided pitch of the "R" raster should be followed as much as possible (see individual types). Different lengths are of course possible, but they require larger manufacturing costs. The maximum manufacture length is limited to 6000 mm for galvanized sections. Based on the required loading and material, the thickness of sheet and the width of sheet section are determined.
• Perforated planks are bent to C sections using a CNC machine.
• Sheet sections with shape adjustments are usually edged with strap steel with the height identical to the height of section
• Sheet sections can be supplied also with welded kick plates.
• Galvanizing is performed according to DIN EN ISO 1461

  Process Details
  1. Choose the material.
  2. Choose material sheet gauge.
  Sheet metal thickness is measured by the gauge. The larger the gauge, the thinner the material.
  3. Choose/design a perforation pattern.
  4. Perforate the sheet metal via bending, welding, punching, cutting, etc.
  Sheet metals perforation is performed using two likely methods, depending on the repetitiveness, complexity and general design of the hole patterns. Simple perforations may be fabricated using a standard punching press, which is a large press containing whatever hole pattern the manufacturer requires. To achieve the desired perforation, sheet metal is simply fed through the press, which punches it. For more complex perforation designs, like decorative panels that use many non-repetitive shapes, manufacturers use a sectional XY axis punching press. This press is usually CNC controlled, thus ensuring precision and accuracy.
  5. Perform any finishing processes.

Forward Filter is a factory with more than 10 years’ experience producing Stainless Steel Spiral Welded Perforated Tube in Petrolium Filtration with High Pressure. Our material is higher quality than normal level of other factories and we offered many big brand machinery companies in our domestic market and abroad market

Stainless Steel Spiral Welded Perforated Tube is applied in many industries area like petroleum refining filtration or oil producing filtration, hydraulic filtration, food filtration producing, drainage system, Light decoration, Vehicle Exhausts or Acoustical Dampening products.

Besides Stainless steel, we also can use other materials like galvanized steel , carbon steel and other alloy.

Perforation hole pattern is variety, which can be round, square and blinds

As for the seam style, we usually use spiral formed, if you have more than one hundred thousand meters require, we can accept custom-made.
