On edge, with one tube above the other. This way it has about 10 times the bending resistance of the GF-N tube: over a 1000 mm span it takes about 1950 N at mid-span with 5 mm of deflection. Flat it takes 388 N, only twice a single tube.

The dedicated external connector GFJ-D28: it joins the W at 90° and holds 1000 N against slipping, 450 N against pull-out and 50 N·m vertically. GF-N internal connectors also fit the W.

It depends on span, number of cross members, joints and feet. With the W the cross member is rarely the weak point: joints and supports matter more. Send us dimensions and load and we will calculate the load capacity of the structure.

The T is a single Ø 28 tube about 1.5 times stiffer than the standard tube: you use it when you do not want to change footprint. The W is 65 mm high but on edge it is about 10 times stiffer: it is the choice for long cross members and loaded shelves.

When the uprights are doing most of the work, or you need sturdier joints and feet: the GF-G Ø 43 series has 1700–2500 N connectors and the 5800 N M16 threaded insert. You can also combine GF-G uprights and GF-N cross members with the mixed connectors.

With 28 series inner plugs on each tube: aluminium, expanding, rounded or ESD.

The standard GF-N profile is suitable for most uprights and cross members. If a cross member is long or loaded use the GF-N W mounted on edge (about 10 times stiffer), or the T (about 1.5 times) or the Hard (about 1.7 times, also for joints that take impacts), which have the same diameter. To fix plate castors, panels or rollers with T-nuts choose the profile with C10 slot; F35 and F50 have a flat flange for labels, small parts holders and supports. The sliding profile has a smooth surface for sliding parts and boxes, the round roller profile becomes a roller with the pin connectors, LS and LS with S slot carry a linear slide and the linear guide profile is the track for the linear rollers.

The GF-N Ø 28 is the standard for workstations, flow racks and trolleys. The GF-S Ø 19 weighs about half as much (0.20 kg/m versus 0.37) and is for light frames, dividers, guards and small mechanisms. The GF-G Ø 43 is for uprights and cross members that have to carry a lot: over a 1000 mm span it supports 851 N at the centre versus 195 N for the GF-N, for the same deflection. It is often worth mixing them, for example GF-G uprights and GF-N cross members joined by mixed connectors.
