Bracket Selection
Characteristics of high tension magnesium aluminum zinc steel plates, resists salt corrosion, self-repairing, and resistant to alkali and ammonia.
The coating is primarily composed of zinc, produced from magnesium aluminum zinc steel plates and trace elements. It is certified to conform to international industrial specifications.

Precaution
Design
Use Tech-Stell locking screws. Tech-Stell Co., Ltd., uses the rotation of the six wedge surfaces above the washer to produce reverse mechanical force (converting transverse force to longitudinal force). The 12 lines on the washer’s other action surface will tightly bite into the surface of the connected item to achieve stable torque and a locking effect.
Material
Medium-carbon steel with a strength of ISO 8.8 and exterior rust prevention processing (zinc and tin alloy) processing.
