There was a time when companies didn’t really have a choice on the type of barrier they implemented in their facility.
If a manager decided there was a need for a barrier – say, for protection, or segregation, or guidance – it usually meant a trip to the local steel fabricators with a pencil drawing, a few measurements and a request for them to ‘knock something up’. When the Armco-type barrier arrived it was then a case of casting and bolting it into a slab of concrete and standing back and admiring the work… until a forklift truck hit it.
