Welded Cleats, End Plates and Connections

Cleats, end plates and base plates welded on before the steel is delivered, so the frame goes together on site instead of being made there.

Get this priced with your steel

Send us your engineer’s drawings and we’ll price the steel and the processing together — one order, one delivery, one point of contact.

What a connection has to do

A beam on its own is only part of a structure. Wherever it meets a column, a padstone or another beam, something has to carry the load across the joint, and on domestic and light commercial work that something is usually a welded plate with bolts through it.

End plates weld across the end of a beam and bolt to whatever it meets. Fin plates and cleats weld to the side of one member and bolt through the web of the other. Base plates sit under a column and spread its load into the foundation or padstone below. Which arrangement your job gets is a decision for the engineer.

Why have them welded on beforehand

Site welding on a domestic job means getting power, plant and a competent welder into an occupied building, usually at height, usually in a confined space, and usually with hot work going on in a room full of timber and finished surfaces. It is slower and more expensive than the same weld done beforehand, and a good deal more disruptive to whoever is living there.

There is an install benefit too. Steel that arrives with its plates already on gets lifted, lined up and bolted, and the opening is done.

Goal post frames

The most common fabricated assembly in domestic work is the goal post frame, a beam with a column at each end, fabricated to the engineer’s connection details and delivered as a complete assembly instead of loose members. See steel goal post frames for when you need one, what it is made of and the sections commonly specified.

What we need from you

We need the connection details from your engineer or fabricator. Plate sizes and thicknesses, weld specification, bolt sizes, hole positions. Fabrication drawings are ideal.

If all you have so far is the structural calculations and a set of member sizes, say so when you enquire. Connections normally need detailing before anything can be welded, and finding that out at quote stage is a lot cheaper than finding it out after the order.

Connection design is engineering, not fabrication. Plate sizes, weld type and bolt arrangement have to be specified by a structural engineer. We fabricate to the details you supply and we do not design the connection. A connection worked out on site is exactly the sort of thing Building Control will query.

Common questions

Can you supply a complete goal post frame?

Yes, fabricated to your engineer’s connection details and delivered as a set. Send the drawings and we will price the whole frame.

Do you design the connections?

No. Connection design is the structural engineer’s responsibility. We fabricate to the details you supply.

Can plates be welded to a beam that is also galvanised?

Yes, but the order matters. Welding is done first and the assembly galvanised afterwards, so tell us at quote stage if both are needed.

What if my engineer has only given me beam sizes?

Tell us when you enquire. Connections normally need detailing before fabrication, and it is much cheaper to establish that before the order than after.

Ready for a price?
