THE WALL THICKNESS Welded thin-wall tube made of cold rolled steel sheet with very high
tensile strength (700-800 N/mm^2).
FIMM first developed this technology offering light and strong handles.
The wall thickness and the tensile
strength of the metal are the most important factors determining the strength
of the handle and heavily influencing the cost.
FIMM has the policy to guarantee these features (see the page Quality
Assurance) within very strict tolerances.
FIMM deplores the fact that some competitors don't supply correct thickness
and strength cheating the buyers and obtaining unfair profit, even if quoting
cheaper prices.
