Start LearningLarge County Council
For the last 18 months we have fully adopted a HAPAS approved reinstatement system for ironwork and we have had no failures at all. As a result of this, we have also now upgraded the County’s Code of Practice for Ironwork so that the use of HAPAS & CD534 materials are specified.
