GF-S W profile

Name: GF-S W profile
Brand: LeanProducts
SKU: GFF-406

Green Frame twin Ø 19 mm tube profile, 44 mm wide: upright more than 10 times stiffer than a single GF-S. Light, stiff cross member for small structures. 0.41 kg/m, 4000 mm bar or cut to length.

GF-S W profile: twin Ø 19 mm tube for light, stiff cross members

Two Ø 19 mm tubes joined into a 44 mm wide profile. Mounted upright it has a moment of inertia of 2.87 × 10⁴ mm⁴, more than ten times a single GF-S and more than twice the GF-N tube: it is the stiff cross member of the light series. It weighs 0.41 kg/m.

Why choose it

Stiff upright

One tube above the other: moment of inertia more than ten times a single GF-S.

Lightweight

0.41 kg/m, almost the same as a GF-N tube, but stiffer upright.

Thin

Each tube is Ø 19: stiff cross members with compact dimensions.

In the GF-S series

The ends are closed with standard GF-S end caps.

Choose it if…

You need a stiff cross member in a GF-S structure.
You want more stiffness than the GF-N tube for little more than its weight.
The cross member must stay slim.

Choose another solution if…

The cross member carries workstation loads: twin Ø 28 tube: GF-N W profile →
A single, stiffer Ø 19 tube is enough: GF-S Hard profile →
You need a plain Ø 19 tube: GF-S profile →

Application example

The GF-S W is used as a cross member in light structures:

Cross members of small workbenches and supports
Frames for guards and light panels
Light shelves with longer spans than a single GF-S

Upright or flat

Always mount it upright where it has to carry a load:

Upright

Moment of inertia 2.87 × 10⁴ mm⁴, section modulus 1.30 × 10³ mm³.

Flat

0.53 × 10⁴ mm⁴: about twice a single GF-S tube.

Joints

We will specify the GF-S connectors to join it to the uprights.

For workstation or shelving loads, move to the GF-N W, which has a dedicated 1000 N connector.

The LeanProducts service

From drawing to finished structure, with a single point of contact:

Design and load calculation

We start from your sketch or dimensions: we choose profiles and connectors and check spans, joints and loads.

Cut to length

We cut the profiles in our workshop to the lengths in the design, ready to assemble.

Kit or assembled structure

You receive the kit with the cut parts and the list of components, or the structure already assembled.

Spare parts and modifications

When the process changes we supply components and new cuts to modify or extend the structure.

Send us a sketch, a photo or the overall dimensions: we will reply with codes, quantities and cut lengths.

Upright, with one tube above the other: this way the moment of inertia is 2.87 × 10⁴ mm⁴, more than ten times a single GF-S. Flat it is worth about twice a single tube.

Upright, yes: 2.87 against 1.16 × 10⁴ mm⁴, with a similar weight (0.41 against 0.37 kg/m). GF-N, however, has the widest range of connectors, feet and accessories.

The GF-N W joins two Ø 28 tubes: 65 mm high, 11.66 × 10⁴ mm⁴ upright, 0.79 kg/m, with a dedicated connector. It is for loaded shelves and cross members. The GF-S W is the light, slim version, for GF-S structures.

GF-S Ø 19 series connectors: we will confirm the models when we prepare the component list.

With the GF-S inner end cap GFA-403 on each of the two tubes, the same as for the standard GF-S.

As a stiff cross member in small workbenches, supports, guards and frames for light panels, where a single GF-S would bend too much.

The GF-S profile is the basic Ø 19 tube. The one with C6 slot adds a slot for slot nuts, hooks and accessories. The Hard has a thick wall, almost double the moment of inertia and an M8 threadable end for feet. The W joins two tubes into a 44 mm wide profile, more than 10 times stiffer when mounted upright. F35 and F22 have a flat flange for labels, tags and light supports.

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.
