Steel parallel flange channels (PFCs)
can be found almost universally in construction projects throughout the world.
They are hugely popular because of their high strength to weight ratios and
their durability. When it comes to choosing PFCs in construction, size does
indeed matter for several reasons. In this post, we take a closer look at what
exactly these reasons are so that you can make a more well-informed decision
when it comes to your own construction project.
Why Does Size Matter for Parallel Flange Channels?
The size and dimensions of your steel PFCs are important for a number of reasons, including:
Structural Strength and Load Bearing Capacity
Because PFCs are most commonly used
for structural support in a building or structure, their strength and load
bearing capacity become important considerations. PFCs that do not have the
required load bearing capacity may buckle or fold under pressure, leading to
issues with the structural integrity of the building. Larger PFCs tend to be
stronger and have higher load bearing capacities and the depth, flange width
and web thickness can collectively influence how much weight a PFC is able to
hold.
Compatibility with Other Structural Components
Dimensions is also important for ensuring compatibility with the other structural components that you are going to be using for your project. PFCs cannot be used alone in construction and are often used alongside universal beams, universal columns and other steel sections. Having the right sizes and dimensions for your PFCs ensures proper connections, bolting and welding, preventing misalignment or weak joints.
Weight
Considerations
Large PFCs also tend to be heavier
and this can lead to higher transportation and installation costs. Choosing the
smallest effective size that does not compromise the overall structural
integrity of your project can therefore be beneficial, helping you to minimise
material costs while still maintaining strength.
Stability and Deflection Control
The depth of your PFC can also affect its ability to resist bending and deflection, with deeper sections providing greater strength and stability for load-bearing applications. If a PFC is too small for the for the load that it is intended to carry, it may also bend or fail, leading to structural issues. Thus, depending on how much bending or flexing that a structure can tolerate, a structural engineer would be able to select the most suitable PFC size and dimensions.
Getting
Your Steel PFCs from a Reliable Supplier
Getting your steel PFCs from a
reliable supplier is crucial for ensuring compliance with industry standards
and maintaining the structural integrity of your project. RW Steel is a leading
supplier of retaining wall steel in Melbourne and we offer one of the
largest selections of PFCs for you to choose from, with sizes ranging from 100PFC and 150PFC to 200PFC22.9. We also offer various
additional services, including complimentary cutting of your PFCs to your
required length at no additional costs. Contact us today to find out more about
