Precision 2Cr13 Stainless Steel Metal Ruler Metric Scale

Product Overview:

Engineered for enduring accuracy and professional durability, our Precision Stainless Steel Ruler is an indispensable measuring and drafting tool for engineers, carpenters, machinists, and students. Formed from high-grade 2Cr13 stainless steel via one-time punching and cutting, this straight ruler delivers an exceptional hardness of $\ge$30 HRC to resist bending, warping, and edge nicks. Featuring dual-sided bold metric scales deeply engraved by laser and a protective clear varnish coating, it provides ultra-crisp visibility, corrosion resistance, and reliable precision.

Key Features:

Premium 2Cr13 Stainless Steel ($\ge$30 HRC): Stamped and cut from a single piece of 2Cr13 stainless steel with certified hardness of at least 30 HRC, ensuring superior structural rigidity and resistance to bending or edge denting.

Laser-Engraved Dual-Sided Bold Metric Scale: Deeply laser-etched graduations with high-contrast bold font on both sides provide glare-free readability that will never fade, rub off, or peel.

Seamless Monolithic Stamped Body: Precision-cut from a continuous sheet of steel with straight, burr-free edges for exact straight-line drawing and scribing.

Polished Surface with Anti-Rust Varnish Coating: Smooth polished finish coated with a high-adhesion protective varnish, preventing oxidation, tarnishing, and corrosion from hand sweat or jobsite moisture.

Convenient Hanging Hole: Built-in hanging hole at one end allows easy hanging storage on pegboards, tool walls, or workshop hooks.

Available Sizes & Thickness:

Lengths: 15 cm (6"), 20 cm (8"), 30 cm (12"), 50 cm (20"), 60 cm (24"), 100 cm (40").

FAQ

Q1: What are the benefits of 2Cr13 stainless steel with \ge$30 HRC hardness?

A:2Cr13 stainless steel provides significantly higher tensile strength and hardness (\ge$30 HRC) than standard 201 or aluminum rulers. It resists bending, nicking, and scratching, ensuring a long-lasting true straight edge.

Q2: Will the laser-engraved scale markings wear off with frequent friction?

A: No. Laser engraving physically etches the graduations into the steel beneath the protective varnish layer, making the bold scale permanent, wear-resistant, and immune to peeling.

Q3: Can the ruler be used as a cutting guide with utility knives?

A: Yes. Thanks to the $\ge$30 HRC hardened steel construction and precision-cut straight edge, it provides a safe, straight, and durable guide for utility knives without damaging the ruler edge.

Q4: Can we customize conversion tables or Imperial scales on the reverse side?

A: Absolutely. We can customize the reverse side with inch scales, fraction-to-decimal conversion tables, tap drill size charts, or custom branding based on your market requirements.

Q5: What is the MOQ and production turnaround time for OEM custom orders?

A: The standard MOQ for custom laser branding and custom PVC sleeves is 1,000–2,000 pcs. The average mass production turnaround is 20–30 days upon artwork and sample confirmation.
