Filling block of protection layer of reinforcing steel bar produced by our company makes up disadvantages of traditional protection layer of cement filling block, protection layer with plastic filling blocks greatly improve the appearance and convenience of the project. This product is mainly used for concrete components, such as column panel of large scale girder. The filling blocks should be laid under reinforced steel bar. Embed this filling blocks while irrigate the concrete to leave certain distance between reinforced steel bar and surface of components, that is to form protection layer of reinforced steel bar. Square filling blocks and flat ones should be used for every meter. Filling blocks with different specs can be selected in line with diameter of reinforced steel bars of users.
