Universal Columns are the most frequently used section for construction their small depth makes them ideal for load bearing when height is limited. Due to their shape they are often referred to as “I sections” or “H Sections”. The Universal Columns width is usually roughly the same as its depth.
Just to add confusion both Universal Beams and Universal Columns are also referred to as “I sections” or “H sections” the difference is easy to spot as the depth of the Universal Beam is greater than its width. The advantage of the beam is that it has a higher loading capability, however often space is an issue and therefore a column would be used.
A Parallel Flange Channel is sometimes referred to as a “Channel” or “C Section”. The Channel is used for columns, lintels above doors to give support to floor joists. If you are using a Channel as a lintel it will need a bottom plate added to it to take the outer bricks, alternatively 2 Channels could be fixed back to back to support both leafs of a cavity wall.
Hollow Sections come as Rectangular, Square and Circular
Rolled Steel Angle – Equal sometimes referred as an “Equal Angle” or “L Shape”
Easy to identify as the “legs” are the same length. Usually used for structural steel brackets and cleat connections.
Rolled Steel Angle – Unequal sometimes referred to as “Angle” or “L shape”.
Often used as lintels as with the longer leg in the vertical position it has a greater loading capacity to and Equal Angle.
Flat Sections are used anywhere a connection between 2 beams is required. Flat Sections are used as base plates. end plates. Stiffeners. tabs, gussetts, splice plates. When a Flat Section is cut into smaller pieces it is called a Plate. Flat sections are often used to strengthen other beams and are sometimes used to reinforce timber joists
Base Plate – Base Plates are used as a support for columns coming off a concrete pad or foundation.
End Plate – Used to anchor the end of a beam to the wall or as part of an end plate connection
End Plate connection – This is used to join a column to a beam or another beam onto a flange
Moment Connection – Features an overhanging plate that bolts into the column. Used when a wall is replaced with a box frame that will need to withstand high wind loads from the side.
Cleat – Used to bolt one beam into the side of another beam.
Spacer – beam
When space is tight a solution is to use two smaller beams and to bolt them together to ensure stability and resistance to buckling
Spacer – PFC
Used when a cavity wall needs to be supported above an opening.
Crank 90 Degrees – Used most frequently to support roof structures
Kink 90 degrees – Used as a bracket or when a beam needs to be supported by a colomn
Kink – Angle
A single kink that follows the pitch of the roof
Kink with plate – The same as a Kink Angle the plate is used when the two sections are of different sizes
Dogleg – Often used for supporting a staircase
Gusset – Usually triangular and used to provide additional stiffness
Usually added to the beam to support brickwork or timber joists.
Top Plate – The is a plate added to a beam when it is smaller that the wall it is carrying
Stiffener – Provides additional stability preventing buckling
Tab – Welded onto hollow column sections to make it possible to anchor them to walls
Hole – flange
A hole drilled in column flange in order to anchor them to walls
Hole – web
A hole drilled into the web of the beam to enable timber joists to be fitted
Splice A1 – A Splice is required when a beam spans two party walls for ease of installation, or, when a beam of either too long or too heavy to install
Splice A3 – Is used to align two sections and would need additional support either with a column or pad stone
