The straight ruler is made of aluminum alloy, making it anti-rust and anti-corrosion, as well as hard and durable. This construction ensures that it is not easily deformed or damaged, thereby ensuring measurement accuracy. This is an aluminum alloy ruler that has an anodized surface treatment, ensuring lightweight construction while significantly enhancing its wear resistance and anti-corrosion performance. The ruler features ink printing technology on its surface, ensuring that the scale is clear, remaining non-fading and non-blurring even after long-term use. It has a dual-scale design, and the back is carefully printed with a complete set of conversion formula for metric and SAE units, allowing beginners to quickly master unit conversion skills. Additionally, it includes a hanging hole design for convenient storage and accessibility. The dual-scale straight ruler is widely used in geometric drawing, plane drawing, composition planning, and mathematical chart drawing; it is suitable for classrooms, architectural design, art design office occasions, and other work environments that require precise measurement or drawing. Try to avoid collision of the ruler with hard objects to prevent damage to the scale and affect the measurement accuracy. Please do not bend the folding ruler to maintain its accuracy and stability.
