GF-G Hard profile
Thick-walled Green Frame Ø 43 mm tube: about twice the bending resistance of GF-G, for joints subject to impacts. The GF-N Ø 28 slides inside. 1.57 kg/m, 4000 mm bar or cut to length.

GF-G Hard profile: thick-walled Ø 43 mm tube for joints under impact
The thick-walled GF-G Ø 43 mm tube: its bending resistance is about twice that of standard GF-G and it is designed for joints that take constant impacts. A GF-N Ø 28 tube slides inside it: with two tubes from the system you make sturdy telescopic uprights. Weighs 1.57 kg/m.
Why choose it
Withstands impacts
For joints that take constant knocks: trolleys, stops, pushed structures.
Twice the strength
About twice the bending resistance of GF-G, with the same diameter.
Telescopic uprights
The GF-N Ø 28 tube slides inside: adjustable uprights with standard components.
Instead of GF-G
Use it only at the most stressed points; the rest of the structure stays in GF-G.
Choose it if…
- The joint takes constant impacts.
- You need more strength while staying with the 43 diameter.
- You want telescopic uprights with a GF-N tube inside.
Choose another solution if…
- The standard Ø 43 tube is enough for you: GF-G profile →
- You need stiffness on the cross members, not on the joints: GF-G W profile →
- The structure is in Ø 28: GF-N Hard profile →

Application example
GF-G Hard is used at the points of the structure that work hardest:
- Joints subject to impacts on trolleys and handling structures
- Telescopic uprights with an inner GF-N tube
- Legs of heavy structures
How to use it
Where the Hard version makes the difference:
In joints under impact
Use it as the tube the connector clamps onto where the structure takes constant knocks.
Telescopic
Slide a GF-N Ø 28 tube inside the GF-G Hard and adjust the height.
Closed head
The head is closed with the dedicated inner plug GFA-426.
We will tell you how to lock the telescopic tube according to the load.
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 project lengths, ready to assemble.
Kit or assembled structure
You receive the kit with the cut pieces and the component list, 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.
