Aluminium strut profile 45x90L slot 10

AL Modular System · C10 profiles

Aluminium strut profile 45x90L

The 45x90L is the light version of the 45x90: same dimensions, same six 10 mm slots and same accessories, but 3.0 kg/m instead of 4.2. Upright it has Ix = 82.0 cm⁴: it suits crossbars of benches, frames and guards. It is also the base profile of LF6C roller guides.

Why choose it

Less weight

About 30 % lighter than the solid 45x90, for the same footprint.

Stiff when upright

Ix 82.0 cm⁴ upright compared with 23.6 flat.

Base for roller guides

In LF6C guides it carries the clamping profiles and the guide rods of the carriage.

The 45x90L weighs 3.0 kg/m and has Ix 82.0 / Iy 23.6 cm⁴; the solid 45x90 weighs 4.2 kg/m, has 124.6 / 32.8 cm⁴ and the heavy slot. Same cover cap and same brackets: for normal loads the 45x90L is enough.

The 45x90 weighs 4.2 kg/m, has Ix 124.6 and Iy 32.8 cm⁴ and heavy-geometry slots. The 45x90L weighs 3.0 kg/m and has 82.0 and 23.6 cm⁴. They have the same dimensions and use the same cover cap and the same 45x90 brackets.

Yes: it is the base profile of the LF6C roller guide, with two clamping profiles, two guide rods and the carriage. The driven version uses the 45x90L with LF machining. The parts list is in the attached catalogue pages.

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.
