Introduction: It is a new applied type building open angle-protecting mesh., it is made up by joint steel bar and pull-joint mesh, the pull-joint mesh form the =90° Angle through the joint steel bar, there are round hole on the pull-joint mesh which is parallel with the steel bar. The new applied type can protect and enforce the open angle, avoid the open angle falling off, distortion, crazing. The cost is low, the structure is simple, and can be operate shortcut, the construction is convince. It has the widely practicability
