This metal triangle ruler is made of aluminum alloy material, with high hardness, good toughness, and light weight. The surface with anodizing treatment to form a dense protective film, effectively prevents water and corrosion. And it is smooth and flat, with precise control of angle tolerances, providing a solid foundation for height measurement and angle calibration.Adopting a standard isosceles right angled triangle structure, integrating dual core symmetrical angles of 45 ° and 90 °, the isosceles structure ensures precise symmetry of the double angles which smaller than 90 degree and can perfectly adapt to the requirements of symmetrical angle processing and detection. At the same time, the ruler body adopts a thickened design to enhance rigidity and prevent deformation.
