Structural framing · PG30 rectangular

A 60 x 30 mm six-slot strut profile is a rectangular aluminium extrusion, 60 mm wide and 30 mm deep, with six T-slots. There are two slots on each of the 60 mm faces on a 53 mm pitch, one slot on each 30 mm end face, and the two centre positions sit 30 mm apart. The groove is 8.2 mm with a 6 mm mouth, so it takes 30-series M8 hardware. The centre bore is Ø10 mm tapped M12, the corner holes are Ø4.5 mm tapped M6, and the wall is 2.2 mm at the flange and 8 mm through the web. We extrude it in 6063-T5 and supply it cut, drilled, tapped or machined.

The important thing about a 2:1 rectangle is that it is not a bigger version of a 30 x 30. It is a directional member: standing with the 60 mm dimension vertical it is roughly four times stiffer than the same section lying with the 30 mm dimension vertical. That makes it efficient where the load direction is known and wasteful where it is not — and it makes orientation a decision that has to be made on the drawing, exactly as it is on a flat beam.

60 x 30 six-slot section: two 8.2 mm grooves per wide face on a 53 mm pitch, end-face slots on 30 mm centres and an M12 centre bore.

A 2:1 rectangle is a beam that knows which way it bends

Put 60 mm of depth in the load direction and the material is spread far from the neutral axis, so the section is stiff. Turn it 90 degrees and the same material sits half as far out, so the section is roughly four times softer. The section does not care which way it is installed; the load does. So the first thing to settle on any drawing that uses a 60 x 30 is which face is vertical, and that decision then fixes where every fixing goes.

This is also why a 60 x 30 is often a better answer than a 30 x 30 where the available space is rectangular. A cabinet upright, a conveyor side rail, a machine guard post and a wide panel edge all have a tall, narrow space to fill, and a rectangle uses that space more efficiently than a square that has to be oversized to reach the same stiffness.

Section	Stiffness on edge	Stiffness flat	Weight
30 x 30, three slot	approx. 3.6 cm4	approx. 3.6 cm4	approx. 0.95 kg/m
60 x 30, six slot	approx. 38 cm4	approx. 9.5 cm4	approx. 1.40 kg/m
90 x 30, eight slot	approx. 120 cm4	approx. 12 cm4	approx. 1.90 kg/m

The pattern in that table is the whole argument for rectangular sections: going from 30 x 30 to 60 x 30 roughly multiplies the on-edge stiffness by ten while the weight rises by less than half. Going on to 90 x 30 multiplies it again while the weight rises by about a third. Where the depth direction is free, a rectangle is almost always the lighter way to buy stiffness.

Why cabinet uprights want a wide face

An electrical cabinet or a control box is a frame with a door on one side and equipment on the others, and the uprights have to do three jobs at once: hold the cabinet square, carry the door, and provide mounting for everything inside. A 60 x 30 upright on edge does all three because it has a wide, flat, slotted face facing into the cabinet. That face is what makes the difference — it carries two rows of devices side by side without them competing for the same slot.

Two rows on one faceThe 53 mm pitch across the wide face puts two grooves on the same surface. DIN rail, terminal blocks, cable ducts and gland plates can be laid out in two columns on one member instead of needing a second rail.

Door and hinge supportA cabinet door is a heavy cantilever load on the hinge post. The 60 mm depth of the upright resists that bending far better than a 30 x 30 would, with the hinge bolted through the end-face slot.

Square without diagonalsBecause the wide face is stiff in the cabinet plane, a welded or bolted cabinet frame built from 60 x 30 uprights holds its shape without needing diagonal braces, which keeps the inside of the cabinet clear for equipment.

Cutting and machining the 60 x 30

A rectangular section behaves differently on the saw and on the mill from a square one, and two details are worth building into the drawing before the order goes out.

Fix the orientation on the drawing and on the cut list Because the section is directional, a member cut to length is not interchangeable with the same member turned 90 degrees. Mark the orientation so the holes are put in the correct face.
Watch the web when drilling the wide face The 2.2 mm flange is thin, so any hole in a wide face should be positioned in the slot or through the 8 mm web rather than through the flange between slots.
Use the end-face slot for door and hinge fixings The 30 mm end faces each carry a slot, which is the natural place for hinge plates, corner brackets and connectors. It is also the face most often forgotten when the drawing is laid out.
Allow for twist over long lengths A 60 x 30 upright over 2 m will twist slightly more than a square section of the same weight, because the rectangle is less resistant to torsion. Where the cabinet is tall, brace the frame at mid-height or specify a heavier wall.

Selection rule: if the load direction is known, use a rectangle on edge. If the load direction can change, or the member is also acting as a post in compression, a square section is the safer choice because it behaves the same way in both directions.

Frequently asked questions

Is 60 x 30 stiffer than 30 x 30?

On edge, roughly ten times stiffer in bending for about half again the weight. Laid flat it is only about two and a half times stiffer. That is the point of a rectangle: it buys stiffness in one direction only, and only if the orientation is right.

Can I use it as an upright post?

Yes, provided the compression load is applied along the member and the section is oriented with the 60 mm dimension facing the load. Where a post has to carry compression and may be loaded from any direction, a square section is safer.

How many slots does it have and where?

Six. Two on each 60 mm face on a 53 mm pitch, and one on each 30 mm end face. The two centre positions on the wide faces are 30 mm apart, which is what allows two rows of devices on one face.

What is the maximum span?

On edge and lightly loaded, up to about 2 m with an acceptable deflection. Where the member carries a door or equipment, keep the support centres under about 1.2 m and send us the load case for a check.

Do you supply it cut and drilled for a cabinet layout?

Yes. We cut to +/-0.5 mm, drill and tap to the cabinet layout, and can supply the uprights bagged by cabinet so the assembler is not sorting members on site.

Send the cabinet layout, get an upright schedule

Tell us the cabinet height, the door weight and what goes inside. We will confirm the orientation and the section, then quote cut lengths, drilling and FOB pricing.
