AL Modular System · C10 profiles
Aluminium strut profile 90x90SL
The 90x90SL is the super-light version of the 90x90: eight 10 mm slots, same envelope and 3.8 kg/m versus 6.5 for the 90x90L. Use it where you need the 90 mm size and lots of slots, but loads are moderate: frames for guards and enclosures, partition walls, movable structures.
Why choose it
Lightweight
3.8 kg/m: about 23 kg for a full bar.
Eight open slots
Two slots per side for connections and panels.
Connector for SL profiles
The tensioning connector has a version for 45x…L, 45x90SL and 90x90SL.

The SL weighs 3.8 kg/m with Ix = Iy 130.2 cm⁴, the 90x90L 6.5 kg/m with 211.1 cm⁴. If the structure carries moderate loads, the SL saves you about 40 % of the weight.
The cover cap for profile 90x90L, in signal grey PP or ESD black.
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.
