Wire spacers BT
Type “BT” wire spacers serve to support the top reinforcement layer or ensure the spacing between the reinforcement layers. Type “BT” spacer reinforcement cages are located on the bottom reinforcement layer and therefore do not have any contact with the respective base (formwork) and can therefore be used in special applications, for example if a ceiling is reinforced with exposed concrete on its underside.
Type “BT” spacer reinforcement cages are only available in a certified version that meets the requirements and regulations of DIN 1045-3:2012-3, as well as the descriptions of “DBV Merkblatt Unterstützungen” (DBV Fact Sheet “Supports”).
