Bending Perforated Steel Tube
21mm tube
Wall thickness: 2mm
Perforated with 4mm and 6mm holes.
Pipe length 340mm
Material: Steel
Used exposed to heat and oil

100mm OD Perforated Steel Tube
100mm OD perforated steel tubing
Used as shielding around 1-3/4" exhaust pipe that runs at 1000F.
The perforated tubing connects to a piece of 4" ID flexible exhaust hose.
Perforations allow for air to be drawn in the flexible hose to cool the inner
pipe. This type of perforations is rigid and allows air flow.
Length varies from 9-12" lengths.


Perforated tubes for making high performance exhaust systems for autos.
OD 30 x Thickness 1 mm x Length 6 meter
Perforation type: hole size 3mm, triangler stitch 4mm

Carbon Steel Perforated Tube

Galvanized steel perforated tube for hydraulic filter

Carbon steel perforated tubing is usually hot dipped galvanized to enhance its
corrosion resistance property.

Perforated Stainless Steel Pipe is corrosion resistant, rust resistant,
recycled, ideal for automotive exhaust applications.

Perforated steel tubes are manufactured with round, square, slot holes in
straight or staggered designs.

Materials for Perforated Steel Tubes

Perforated Tube is a kind of Welded Steel Pipe made of mild steel or 409, 439,
304, 316 Stainless Steel perforated materials.

Choosing the proper steel materials according to the properties:
Stainless steel is the most corrosion resisting material, while its alloys vary
specifically to suit different work environment.

Carbon Steel is the most corrosive and therefore, the least expensive of the
three most commonly perforated metals. Produced into coil form by roller
leveling to a desired thickness either once while the steel is still hot or
again after it has cooled, each of the Carbon Steel types listed below are
referred to as either Hot Rolled or Cold Rolled (ex. Cold Rolled Commercial
Steel). The difference in processes result in products that differ in terms of
cost, quality, and mechanical properties. In short, Hot Rolled is typically
less expensive and produced in thicker gauges 7-16, whereas, Cold Rolled
provides tighter tolerances, better surface finishes, and while it can be
produced in practically any gauge, it is most readily available in thinner
gauges 14-28.

Because carbon steel is susceptible to corrosion, it is typically used in
either unexposed applications or protected with a coating. Coatings such as
paint and powder are applied after perforating and completely protect the
material. Zinc based coated metals (i.e. Galvanized, Galvannealed, etc.) on the
other hand, are produced and supplied as such from the mill and may not
completely protect the material where its carbon core is exposed during the
perforating process.

Commonly Perforated Carbon Steel Types
Commercial Steel (HR, CR, GALV) A low cost steel that has good drawing,
forming, and welding qualities, moderate strength, but is subject to strains,
fluting, and breaks due to aging. To reduce the affects caused by aging,
Drawing Steel is recommended.

Drawing Steel (HR, CR)
A steel with a greater degree of ductility and uniformity of properties than
Commercial Steel providing improved performance during manufacturing. This type
is recommended for use when stretcher strains or fluting during fabrication are
objectionable and/or consistency of performance is important.

Forming Steel (GALV)
A steel with lower strength and higher elongation than Commercial Steel.
Recommended when stresses from forming either crack or weaken Commercial Steel.
