The office ruler is made of aluminum alloy, which makes it hard and durable, not easy to deform or damage, ensuring measurement accuracy; the lightweight aluminum alloy ruler is more flexible to operate and convenient for one-handed operation or long-term continuous measurement. The anodized surface can effectively prevent the aluminum alloy surface from corrosion or rusting, extending the service life of the folding ruler.The geometric ruler adopts a center rotation design, which is more stable when rotating, ensuring the accuracy of measuring and drawing angles. The angle scale is clear, and the angle value can be read intuitively to avoid reading errors and improve work efficiency. The folding design takes up little space and is easy to carry and store.
