What is a PFC beam?
What is a PFC beam?
The PFC beam is a versatile section of steel for use as horizontal steel support across large spans or used vertically as a wind bracing portal frame, also frequently located over large windows or door openings used in conjunction with an angle lintel to simultaneously support upper-level brickwork and wall framing.

What does Pfc channel mean?
Parallel Flange Channel
The structural channel, also known as a C-channel or Parallel Flange Channel (PFC), is a type of (usually structural steel) beam, used primarily in building construction and civil engineering.
What is the difference between universal column and universal beam?
Difference between Universal Columns and Beams A Universal column is structured to hold loads along its vertical axis and resist twisting, while universal beams are structured to hold loads along the length of the beam and are structured to resist bending from the weight of the load.
What’s the difference between UB and UC beams?
UC – universal column or UB – universal beam. Unlike a universal beam, the UC’s width is roughly equal to their depth. For example, a 152 UC 23 is 152 mm wide and 152 mm deep and 152*89 UB 16 is 89mm wide and 152mm deep. The last number (23 in this example) is the weight per meter in kilograms.
What lengths does Pfc come in?
PFC Section (Parallel Flange Channel Section) Mascot Steel has a range of universal beams from 9 to 18 metres, including popular sizes 100 pfc, 125 pfc, 150 pfc, 180 pfc, 200 pfc, 230 pfc, 250 pfc, 300 pfc, 380 pfc.
How is Pfc steel measured?
They are described by their depth, width and weight per metre in kilograms, eg. 150 x 75 x 18 PFC. The PFC is used for columns, lintels above doors or simply a beam supporting floor joists.
What is UC in steel?
Universal Columns (UC) are the most often used section for structural steel purposes. Due to their section shape, they are often called “I-sections” or “H-sections”. Unlike a universal beam, the UC’s width is roughly equal to its depth. For example, a 152 UC 23 is 152 mm wide and 152 mm deep.
Which way is C channel the strongest?
In the vertical direction (as oriented for the beam profile chart image above), C-Channel is typically stronger for the weight than tube. That makes it attractive, but it doesn’t come in as many different sizes, thicknesses or varieties.
What does UC mean in steel beams?
Universal Columns
Sections. Universal Columns (UC) Dimensions and properties. Universal Columns (UC) sizes. Designation.
How tall is 230 PFC Parallel Flange Channel?
230 PFC Steel Data 230 PFC Parallel Flange Channel Weight: Overall Width: Overall Height: Flange Thickness: Web Thickness: Root Radius: Moment of Inertia – XX Moment of Inertia – YY 25.1 kg/m 75.0 mm 230.0 mm 12.0 mm
What is the PF of a 230 V circuit?
For instance, a power circuit with a 230-V/5-A rating is limited to about 575 W of available power with a power factor (PF) of 0.5. Increasing the PF to 0.99 almost doubles the deliverable power to 1138 W, allowing the operation of higher power loads.
What is the PFC section of mascot steel?
PFC Section (Parallel Flange Channel Section) Channels are used for support in construction. Mascot Steel has a range of universal beams from 9 to 18 metres, including popular sizes 100 pfc, 125 pfc, 150 pfc, 180 pfc, 200 pfc, 230 pfc, 250 pfc, 300 pfc, 380 pfc.
Is the ucc28180 a programmable frequency PFC controller?
The UCC28180 is a high performance, CCM, 8-pin programmable frequency PFC controller. The wide and programmable operating frequency of the controller provides flexibility to design at a high frequency to optimize the components. The UCC28180 uses trimmed current loop circuits to achieve less than a 5% THD from a medium-to-full load (50% to 100%).
