Aluminium strut profile 100x100L

The 100x100L is the largest square profile of series 50: two 10 mm slots per side and M12-tappable central holes. With Ix = Iy = 318.3 cm⁴ and high torsional stiffness (It 153.5 cm⁴) it is the column for gantries, heavy frames and uprights loaded from several sides.

Why choose it

Stiff in every direction

Ix = Iy 318.3 cm⁴: an upright with no weak axis.

Torsionally stiff

It 153.5 cm⁴: handles off-axis loads well.

Series 50

Two slots per side aligned with the 50 mm grid.

When the upright carries high loads from several directions or significant moments, for example gantry columns and heavy frames. For less loaded uprights in series 50 the 50x50L is enough.

The cover cap for 100x100 L profile; in Odoo you will find the black ESD version.

It is the width of the profile slot and determines which accessories you use. Slot C6 (6 mm) is for 20 series profiles, C8 (8 mm) for the 30 series, C10 (10 mm) for profiles from the 40 series upwards. Nuts, screws, brackets and cover caps are chosen by slot: each accessory's product page shows the right one.

Yes. You can order the full bar or the piece cut to the length you need: we do the cutting ourselves, in our workshop. Each profile's product page shows the maximum bar length and the minimum cut length.

Look at the moments of inertia Ix and Iy: the higher they are, the less the profile deflects under load. For the same section, “L” profiles are lightened and deflect a little more. For long spans or high loads move to a larger section or a tall profile (e.g. 45x90 instead of 45x45). If you send us drawing and loads, we will check the choice.

The T-nut is inserted from the front into the slot, even in an assembled structure, and positions itself when you tighten the screw: it is the standard choice for fixing accessories. The sliding block withstands higher forces, but normally has to be inserted from the profile end before closing the frame; spring versions stay where you put them.

The simplest way is the bracket, which joins two profiles at 90° with screws and nuts in the slot, without machining. For end, T, 45° or three-way connections there are dedicated connectors, some of which require profile machining as stated on their product page.

Yes, for several accessories (for example cover caps, hinges and nuts) there are conductive ESD versions, indicated in the name or variant. Tell us which EPA area you work in and we will confirm the components to use.

On each product page you will find the MGE catalogue pages to download as PDF, with dimensioned drawings and technical data; the Specifications tab shows the data for the variant you have chosen.

Yes. Send us the parts list or a sketch with dimensions: we give you codes, quantities and cut lengths and prepare the kit with profiles already cut and the accessories.
