Steel Ruler:40"/1000mm

This steel ruler is a 40-inch measuring tool constructed from steel for durability. It is standardized to a nominal length of 1000mm, making it suitable for tasks requiring extended linear measurement. Buyers often select steel rulers for their rigidity and resistance to flex compared to flexible plastic or cloth alternatives, ensuring consistent readings across the full span. The product is ideal for industrial workshops and construction sites where long, straight measurements are frequently required. Choose this size when your application demands a reach beyond standard 12-inch or 18-inch rules but does not require the portability of shorter instruments.
