The 60 x 60 mm four slot section. The 14 x 14 mm internal grooves are large enough to carry a cable bundle, and the section is large enough to carry a second route inside it.

01What is the 60 x 60 mm four slot profile?

What is it for?

Column duty on large frames. Machine frames and bases, automation and robot cell columns, access platform and walkway frames, guard frame posts, conveyor support columns, heavy benches and test stands, and storage racking uprights. It is the section you move to when a 40 or 45 series member is strong enough but not stiff enough.

How does it compare with the smaller series?

At about 4.3 kg/m and about 26 cm4 it is roughly 2.5 times the weight of a 40 x 40 for about three times the stiffness. That is the trade in one line: you pay more than proportionally in weight and you get more than proportionally in stiffness, because stiffness scales with the square of the depth.

What is unusual about it?

The 14 x 14 mm internal grooves and the size of the section. Together they give you two separate cable routes on one member: one clipped into the grooves and accessible from outside, and one inside the section, protected and out of sight. Smaller series only give you the first.

02Section data

Item	Value	Note
Envelope	60 x 60 mm	square, column duty
Slots	4	10.2 mm mouth, 14 x 14 mm groove
Slot pitch	48 mm	the 60 series module
Fastener	M8 and M10	60 series slot nuts
Centre bore	12 mm, tapped M14	for end-wise bolting to plates
Second moment of area	approx. 26 cm4	as published
Weight	approx. 4.3 kg/m	a 6 m bar is about 26 kg
Alloy	6063-T5	6061-T6 on request
Standard	EN 755-9 / GB/T 6892	wall tolerance +/-0.15 mm
Length	6 m stock	cut to drawing to +/-0.5 mm

The M14 centre bore is the column detail. It is how the member is bolted end-wise to a base plate or a top plate, and it is the reason this section works as a column rather than just as a big frame member.

03Deflection compared: 40, 45 and 60 series at the same span

The reason to step up a series is almost always deflection rather than strength. A frame that is strong enough will still be rejected if a rail sags or a door drops, and deflection falls with the second moment of area, which grows fast with section depth.

The table below is a relative comparison for the same span, the same load and the same support conditions. It is the way to choose a series, not a design calculation.

Section	Weight	Second moment of area	Relative deflection
40 x 40 mm	about 1.95 kg/m	roughly 8 to 10 cm4	1x, the reference
45 x 45 mm	about 2.7 kg/m	roughly 14 to 17 cm4	about 0.6x
60 x 60 mm, this section	about 4.3 kg/m	about 26 cm4	about 0.33x
80 x 80 mm	about 7 kg/m	roughly 60 cm4 and above	about 0.15x

Read it as: a 60 x 60 member deflects roughly a third as much as a 40 x 40 under the same conditions, for about 2.2 times the weight. Where the consequence of deflection is real — a gantry rail, a long guard rail, a platform edge — that is a good trade.

Where it is not worth it: a short post, a member fully supported along its length, or any place where the extra 60 mm of envelope costs you space you do not have.

Those figures are approximate and are relative comparisons. For an absolute deflection figure, send the span, the load and the support conditions and we will run it against the die drawing.

04Two cable routes on one member

This is the part of the 60 series that gets overlooked on a cut list. A 40 series member has grooves you can clip cable into, and that is the only route you get. A 60 x 60 member has that, and a void inside big enough to run a second route.

The two routes suit different things:

Route	What goes in it	Advantages	Constraints
In the groove	sensor leads, small harnesses, air line clips	accessible from outside, reworkable at any time	limited by groove size, exposed to damage
Inside the section	main power, motor cables, larger bundles	protected, out of sight, no snag points	must be planned before assembly, needs access holes

The rule that makes it work: power inside, signal in the groove. Keeping the two apart is good practice anyway, and the section gives you the physical separation for free. Plan the access holes with the cut list, because once the frame is assembled the inside is no longer reachable.

Note also that running cable inside a column changes the member: it adds weight, and if the bundle is large it reduces the free area in a way that matters for a tall slender column. On a 2 or 3 m frame post it is never a problem. On a 6 m column it is worth a word with the designer.

05Using it as a column

What a column needs

Square end facing so it bears flat on a base plate
The M14 centre bore tapped, with a stated engagement length
A base plate with a footprint that resists overturning
Levelling adjustment, usually a foot or a shim stack
A check on buckling if the column is tall
Access holes for internal cable, planned before assembly

What a beam needs

Cut to length and deburred, ends do not have to bear
No centre bore tapping required
Ends supported on brackets or on other members
No levelling: the supports set the level
A check on deflection, not buckling
Cable in the grooves, where it stays reachable

The two are different jobs and the order has to say which. A column needs the end facing and the M14 tapping specified; a beam does not, and specifying them on a beam is money spent for nothing.

For tall columns, the buckling check is the one that gets skipped. A 60 x 60 member at 4.3 kg/m is stiff, but a 4 m unsupported column is still slender enough that buckling governs rather than crushing. Plan a mid-height restraint if an upright runs much past 3 m.

06Failure modes to design out

What goes wrong	Why it happens	Design it out by
Column does not sit flat on its base	the ends were cut but not faced square	specify square end facing for column duty
M14 thread strips at the base	the tapped engagement is short and the bolt was torqued to the steel figure	state the engagement length and torque to the aluminium figure
Tall column bows sideways	buckling governs on a slender member and was not checked	add a mid-height restraint tied back to the frame
Internal cable becomes unreachable	access holes were not planned before assembly	drill and deburr access holes with the cut list
Wrong series hardware arrives	the order said 60 x 60 and not 60 series	quote the accessory list as a 60 series kit

07What to check before you order

Procurement checklist for the 60 x 60 mm four slot section

Confirm the series: 60 series is a 10.2 mm mouth on a 48 mm pitch, M8 and M10.
Confirm whether the member is a column or a beam, because the end preparation is different.
For columns, confirm square end facing and M14 tapping with the engagement length.
Confirm whether internal cable is planned, and where the access holes go.
Confirm the height of any column and whether a mid-height restraint is needed.
Confirm the accessory list as a 60 series kit: M8 and M10 slot nuts, base plates, cover strips, end caps.
Confirm the finish and the quantity in metres.

08Terms used on this page

Column duty: A member standing upright and carrying compression. It needs square ends and a buckling check.
End facing: Machining the cut end square and flat so it bears properly against a plate.
Buckling: The sideways failure of a slender member in compression. It is governed by stiffness and length, not strength.
Centre bore: The round hole down the middle of the section, here 12 mm and tapped M14 for end-wise bolting.
Second moment of area: How the material is distributed about the neutral axis. It governs deflection.
Access hole: A hole drilled into the side of a section so cable can be routed through the inside.

09Questions buyers ask

Is it worth stepping up from 45 series?

Where deflection governs, yes. A 60 x 60 deflects roughly a third as much as a 40 x 40 under the same conditions for about 2.2 times the weight. Where the member is short or fully supported, it is not worth it.

What is the weight per metre?

Approximately 4.3 kg/m, so a 6 m stock length is about 26 kg.

Can cable be run inside the section?

Yes, that is one of the advantages of the size. Plan the access holes with the cut list, because the inside is unreachable once the frame is assembled.

How is a column fixed to its base?

The 12 mm centre bore is tapped M14 and the column is bolted end-wise to a base plate. Specify square end facing so it bears flat.

Is 60 series compatible with 40 or 45 series?

No. The pitch is 48 mm against 40 mm and 45 mm, so brackets and hole patterns do not interchange. Use adapter plates for cross-series joints.

How tall can a column be?

Plan a mid-height restraint for an upright much past 3 m. Buckling governs on a slender member long before crushing does.
