Jimmy Green Marine MF40 is sourced exclusively and directly from MF Catenificio Frigerio, a modern chain manufacturing plant in Italy.
MF Catenificio chain is manufactured, hot dip galvanised, hallmark stamped and proof tested in their modern research, test and production facility located near Lecco, Lake Como, Italy.
Grade 40 means a guaranteed tensile strenght of 40kg/mm2.
The proof load testing process ensures that each individual weld has been completed successfully.
A Test Certificate is available for your specific length of chain on request.
The MF Catenificio Frigerio Galvanising Treatment is changing to EN ISO 461 Regulated Salt-Spray Tested Hot Dip Galvanising to a micron depth of 80 ± 10 µ.
Hot-dip galvanising anchor chain is a challenging process which involves immersing the chain in a molten zinc bath.
The molten zinc chemically reacts with the surface of the steel to create an iron-zinc alloy.
The result is a deep protective treatment to a minimum depth of 80 microns regulated to the EN ISO 461 standard.
MF Galvanising provides longlasting resistance to abrasion and corrosion.
MF Catenificio hot dip galvanising performance is further guaranteed by stringent application of their state of the art Salt-Spray testing treatment.
The MF Salt Spray Test, developed by the MF Laboratiory Team and introduced in 2023 scrutinises the effectiveness and durability of the galvanising treatment.
The MF testing laboratory conducts a stringent examination of each batch of chain, exposing it to a concentrated salt solution for 24/48 hour cycles.
Salt Spray Testing simulates the real environmental conditions to which the chain will be exposed during its service life.
The results are governed by the MF Catenificio Frigerio UNI EN ISO 9001 certified quality system.
MF Calibrated Anchor Chain features enhanced Solid Zinc Galvanising treatment with greater micron depth and longer lasting corrosion resistance.
The MF Solid Zinc Galvanising Treatment is slowly being phased out.
Production from 2025 will be EN ISO 461 Regulated Salt-Spray Tested Hot Dip Galvanising to a micron depth of 80 ± 10 µ.
MF have developed a Solid Zinc Galvanising treatment in conjunction with the standard hot dip galvanising process.
Solid Zinc Galvanising is an MF duplex treatment where both aspects of the process are hot dip molten zinc galvanisation.
The consolidated, faultless coverage, increased micron depth and improved fusion layer adhesion can extend the working life of the galvanising by up to 25%.
Solid Zinc Galvanising is proven to increase resistance to corrosion by up to 25% compared with standard galvanising.
The exterior finish generally has a more aesthetically pleasing, homogeneous chromatic appearance than standard hot dip galvanising.
However, even the Solid Zinc galvanising process is not infallible.
Flaws and blemishes can occur, but the deeper fusioning effect of the duplex treatment should provide reassurance.
N.B. All minimum micron thickness values are subject to variables and therefore dependent on the size of the chain, so micron depth figures are not specific.
This graph illustrates the relationship between the enhanced micron coverage of Solid Zinc Galvanising and the resistance to corrosion i.e. rust in terms of longevity/endurance in a marine environment. Solid Zinc galvanising is available up to and including 14mm diameter chain.
The entire MF chain manufacturing process has Lloyds Register approval to the ultimate ISO 9001 quality standard: MF Lloyds Register approval to ISO 9001
