Calibrated Chain - Hot Galvanized
When you purchase a
calibrated chain, it’s important to know what chain suits your windlass for the
best fit. The majority of windlasses require chain in accordance with either
DIN 766 or ISO 4565.
A combination of wire
diameter, link outside width and most importantly the chain pitch (inside link
length) must be consistent throughout the length of the chain to ensure the
best fit in the gypsy.
To produce a
calibrated chain the manufacturer would normally weld the chain shorter than
required. It would then be subjected to a further process of calibration. This
process pulls each link to a constant length within a tolerance.
Our calibrated chain
is supplied with a certificate of conformity and test. This confirms that the
chain has been subjected to a proof load and our in-house batch testing ensures
that the chain can withstand the minimum breaking load.
