The loop channel JSA K 38/17 is made of rolled plain or hot-dip galvanised steel. The delivered length is 5960 ±60 mm. The anchoring stirrups are inserted through the loop openings at intervals of 250 mm and bent into shape. If holes are spaced at intervals of 125 mm, stirrups are only mounted in every second loop. In all applications, one anchoring stirrup must be installed at the beginning and one at the end of the channel. The filling is made of polyethylene (PE).
