In the last few years, European technical standards have set the mechanical and dimensional features of anchor chains for the boating industry and have always based the mechanical strength standard to a tensile strength equal to 30kg per mm2. MaggiGroup® has elected to increase the quality of its standard anchor chains to a fully certified tensile strength of 40kg per mm2. Thanks to the careful selection of special steels and high quality processes, MaggiGroup® base products exceed industry standard performance by more than 25% over all other DIN766 chains on the NZ market.................. except one ....
Or with the MaggiGroup® AQUA7 you can have a anchor chain with tensile strength exceeeding 70kg per mm2. That's more than twice as strong as all other DIN766 chains on the market, except the AQUA4. Over three times stronger than some easten made DIN766 chains. Fully Certified.
The diagram shows that AQUA 4 mechanical performance is 25% better and, more specifically, has 25% more tensile strength compared to a grade 30 traditional chain.
Just to add some local flavour for the local viewers in Australasia. Grade 30 is also known as Grade L.We have it available in the DIN766/A, the EN818-3 and the AS2321 (Australian) Standard sizing.
Sure many do look very similar and many would like you to think they are but this photo would suggest otherwise. The boats onwer knows exactly what each chain was, from where and when. Understandably he is not a happy chappy.
The chain on the left was made by the Maggi Group in Italy.
The joiner by Crosby in Canada
The chain on the right was made in China and was sold as being 'equal in quality as the Maggi chains' and it was 'suggested' it was made in a country other than china. It appears that statement was a tad wrong.
Someone either doesn't know the products they sell or was just telling porkies. Are you talking to that same person?
