Base Plate Connection

Base plate is commonly used for supporting a column protruding from a concrete pad or foundation. It is essential to leave a gap of between 20 and 30 mm between steel plates and concrete to ensure stability and longevity. The remaining gap will need to be filled; this is achieved by packing a dry mixture of concrete into the available space.

End Plate Connection

An end plate connection joins a column to a beam, a flange, or another beam. It is a common element of any build.

Moment Connection

A moment connection is frequently used for sections which are required to withstand a high level of stress for a ‘moment’, such as when a wall is replaced with a box frame and needs to withstand high pressures from all sides.

Cleat Connection

A cleat is used to bolt a beam into the side of an adjacent beam. Cleats are made of angle sections bolted to both beams. If only one side needs bolting, only one cleat will be required, and it is often a more desirable method than bolting.

Dogleg Connection

This horizontal beam has a vertical section welded at 90 degrees – similar to that of a dog leg. This beam is often used to support staircases.


Gussets are usually used to support the outer edge of a bottom plate welded to a beam. A gusset uses a triangular plate to provide additional stiffness to a structure.


A stiffener will provide additional stability by connecting flanges and the web. It prevents the web from buckling by adding stiffness.

Bottom Plate

The bottom plate is added to a beam to support timber joists or brickwork. The plate is stitch welded to the beam and can be offset so that the brickwork or timber is sufficiently supported.

Beam Spacers

When projects are struggling for height, for instance in basements and lofts, it is often preferable to replace a deep beam with two smaller beams. However, to ensure stability and resistance to buckling, these beams need to be bolted together; this is where a spacer is used, and it is usually welded to one of the beams. The bolts are typically 600 mm apart from each other.

PFC Spacer

When a cavity wall needs to be supported above an opening, two PFCs can be bolted together back to back, with a spacer in between, to give the walls extra strength. The gap between the sections matches the width of the cavity, and the spacing between the bolts is 600 mm centre to centre.

Crank Connection

The 90 degree crank is similar to a typical crank, except it has two kinks. The top member is horizontal and the bottom vertical. Cranked beams are frequently used to support heavy weight structures such as rooms, requiring the angle of the middle members to follow the pitch of the roof. Full penetration welds must be used with these connections to ensure successful carriage of the load.

90 Degree Kink Connection

The 90 degree kink is a two section connection welded together. Commonly used for brackets or for the support of a column where a bolted connection cannot be used.

Splice Connection A1

When a beam is too long or too heavy to install safely, a splice will be required. If a beam spans two walls, a splice will assist during the installation – otherwise a large section of the wall will have to be temporarily removed. A general rule is that the flange plate must be at least the same thickness as the beam’s flange. The same rule applies to web plates.

Splice Connection A2

Structural engineers may require additional inner flange plates to be attached to the splice connection.

Splice Connection A3

The A3 type splice is not a full strength connection, so it should only be used to align two sections. The A3 needs additional support via a column or pad stone.

Gallow Bracket

Gallow brackets have been used to support chimney breasts for many years. However, many local authorities no longer allow them to be used. If your planning department advises that these are not permitted, then you will need to use a full steel beam structure instead.
