Straight Ruler 12 Inch(30Cm) Metric & SAE Aluminum Rulers With Hole Beige

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 ruler adopts ink printing technology on its surface, ensuring clear and sharp scales that remain non-fading and non-blurring even after long-term use. It also features a dual-scale design, specifically including both metric and inch units to meet versatile measurement needs across different scenarios. The aluminum alloy 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.
