 Description
 
Safety with Grade 80
To achieve the consistent high level of quality and reliability of our products
Electronically controlled chain making machines have been
  specially built and developed to provide advanced manufacturing processing
High grade alloy steel are carefully chosen.
Strict control of material acceptance and processing is
  carried out by skilled persons.
Sophisticated multi-process heat-treatment techniques have
  been developed
Non-destructive testing systems are used with magnetic
  crack detection (magna flux system), being applied during final inspection
All accessories, such as hooks, connectors etc., are
  produced by special hot forging techniques carred out on modern forging hammers.
Close dimensional controls are carried out at all stages
  of manufacture
To ensure the chains have a high capcvity to absorb shock loadings, they are produced so that they will give a minimum extension of 20% under a destruction test before fracture occurs.
They are also subjected to sample bend testing.
