The slender main support columns in Coventry Cathedral will excite comment for many years to come.
Whale brand TUFNOL inserts form an integral part of these columns that visitors will never see.
The steel tensioning ropes pass through the manganese bronze bases beneath the columns. The TUFNOL inserts prevent electrolytic action between the steel ropes and bronze bases.
The TUFNOL inserts also allowed access for the injection of concrete filling after each column was erected.
