Extruded angles are another popular item
to be made of the extrusion process. Here also the most popular item is
aluminium followed by plastics. From building and construction, engineering
equipment extruded angles are used everywhere. In the following section are
discussed extruded angles according to the material type.
Extruded Aluminium Angles
In the category of extruded aluminium angles the following are some of the
popular shapes. The first example is of angle with equal legs.
- Angle with equal legs
It has a wall thickness of 3/16 inches, height of 11/2 inches and width
of 11/2 inches.
- Angle with unequal legs
The next example has a wall thickness of 1/16 inches, height of 1 inch
and width of 11/2v inches.
Extruded aluminum angles are quite popular in grating applications in
the building industry. They can be manufactured using aluminium 6063 T6.
These extruded angles, because of the importance of application are made
anti corrosion and customized to any length.
The following image shows how these extruded aluminium angles of L
shape are used in grating applications.
Extruded Steel Angles
Coming to the extruded angles made of stainless steel, they are used in a
variety of applications. The following image shows extruded steel angles for
constructing bar screen, used in water treatment applications.
Extruded Plastic Angels
Another popular material through which extruded angles are produced
includes the plastic materials. Plastic angle extruded profiles are an
excellent way for a number of applications. For uses as edge protectors,
speedy fabrication of parts etc. The materials
used
varies from soft, flexible to hard and even rigid. The following image shows
an extruded PVC angle rod.
The following table gives a look at the tolerance level of some of the
plastics that are used for making extruded angles. However before applying
this information it is important to evaluate the individual needs.
