Precision 2Cr13 Stainless Steel Carpenter Square Ruler

Product Overview:

Achieve absolute 90-degree accuracy and maximum durability with our Precision 2Cr13 Stainless Steel Carpenter Square. Stamped from a solid single sheet of 2Cr13 stainless steel via one-time punching and cutting, this framing L-square delivers an exceptional hardness of $\ge$30 HRC to resist bending and deformation. Featuring dual-sided bold metric scales deeply engraved by laser and a protective clear varnish coating, it provides clear readability, unmatched corrosion resistance, and long-lasting layout precision for carpenters, builders, and roofers.

Key Features:

High-Grade 2Cr13 Stainless Steel ($\ge$30 HRC): Precision-formed through one-time punching and cutting from premium 2Cr13 stainless steel. The blade reaches a certified hardness of at least 30 HRC, ensuring maximum rigidity and resistance to impact or permanent bending.

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

Seamless Monolithic Stamped Construction: Fabricated from a single piece of steel without joints, welds, or rivets, guaranteeing a permanently reliable, distortion-free 90° right angle.

Polished Surface with Protective Varnish Coating: Smooth polished body is sealed with a specialized anti-corrosion varnish coating, preventing oxidation, chemical corrosion, and extending tool life in harsh jobsite conditions.

Wide Applications (Scope of Use):

Carpentry & Woodworking: Checking right angles, squaring lumber edges, layout of mortise/tenon joints, and cabinet assembly.

Framing & Roofing: Calculating rafter pitches, framing stair stringers, and structural layout.

Metal Fabrication & Welding: Laying out sheet metal, squaring frames, and verifying weldment angles.

Tile Setting & Masonry: Ensuring 90-degree corner alignment for walls, flooring, and masonry work.

OEM & Customization Capabilities:

Available Sizes: 150 × 300 mm, 250 × 500 mm, 300 × 600 mm, and custom dimension options.

Scale Configurations: Metric only, Imperial only, or Metric/Imperial dual scales.

Branding & Marking: Custom laser logo engraving, brand name, and custom graduation tables on the blade.

Packaging Options: Hanging plastic sleeve, sliding blister card, double blister pack, or customized bulk retail carton.

FAQ

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

A: 2Cr13 stainless steel provides superior tensile strength and hardness (\ge$30 HRC) compared to regular 201 or 430 stainless steel, ensuring the ruler will not bend, nick, or deform even under heavy jobsite use.

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: How does the single-piece stamped design ensure 90-degree accuracy?

A: Because the ruler is stamped and cut from a single piece of continuous steel with no rivets, welds, or assembled joints, there are no weak points to loosen over time, ensuring a permanently true 90° angle.

Q4: What is the MOQ and production turnaround time for OEM custom orders?

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