GF-S Hard profile

The diameter is the same, 19 mm, but the GF-S Hard has a thick wall: it weighs 0.56 kg/m instead of 0.20 and has almost double the moment of inertia (0.51 against 0.27 × 10⁴ mm⁴). The end can be threaded M8.

Yes: the central bore at the end is threaded M8 and you screw in a levelling foot or other components with an M8 stem, without a threaded insert. Let us know with your cutting order.

For legs and uprights of light structures that need to bend less or carry a screwed-in foot. The rest of the structure stays in the lighter standard GF-S.

The GF-S W profile joins two Ø 19 pipes into a 44 mm wide profile: mounted upright it has a moment of inertia of 2.87 × 10⁴ mm⁴, more than five times the Hard. Beyond that you move to GF-N Ø 28.

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

With the inner end cap dedicated to GF-S Hard, GFA-443: the standard GF-S end cap is not suitable for this profile. If you fit a foot at the end, the end cap is not needed.

The GF-S profile is the basic Ø 19 pipe. 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 pipes 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.

Yes. Green Frame profiles can be ordered as 4000 mm bars or cut to the length you need: we do the cutting ourselves, in our workshop. Give us the dimensions of the pieces or send us a sketch of the structure and we will prepare the cutting list.

Yes. The standard series is GF-N (Ø 28 mm pipe); GF-S (Ø 19 mm) is lighter and more compact, GF-G (Ø 43 mm) is for stiffer structures. There are mixed connectors that join pipes from different series, for example a Ø 19 or Ø 43 pipe to a Ø 28 pipe, so you use the right diameter at every point of the structure.

No. The connectors are fixed to the pipe with hex socket screws: a hex key is all you need. Loosen the screw, insert the pipe, bring it into position and tighten. No welding, drilling or painting.

Yes, it is the strength of the pipe system: loosen the connectors, move or replace the pipes and retighten. You can raise a shelf, extend a workbench or reuse the components in another structure when the process changes, with continuous improvement in mind.

Yes. We can design the structure (workstation, flow rack, trolley, line-side supermarket) with the load calculation and deliver it to you assembled or as a kit with the parts already cut and the list of components.

No. Profiles and connectors are in anodised aluminium: the surface resists corrosion and wear without painting and is easy to clean.

Yes. The range includes conductive components such as ESD inner end caps, ESD clips for electrical continuity between pipe and connector, and ESD inserts for levelling feet and castors. Tell us which EPA area you work in and we will tell you the components to use.
