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.
