Cold rolled steel delivers higher yield strength, greater hardness, and tighter dimensional tolerances than hot rolled steel, making this rod well suited for structural and fabrication work. It also exhibits excellent forming and welding characteristics, which simplifies cutting, bending, and joining on the job. Licensed contractors, fabricators, and experienced tradespeople working on light structural or support applications are the primary installers of this type of rod stock.\u003c\/p\u003e\u003cp\u003eThis smooth rod is designed for a range of industrial and construction applications including fencing, supports, railing, sign posts, and general framework. It is rated for exterior use and meets ASTM A510 specification, confirming its material composition and mechanical properties for cold rolled wire rod and coarse round wire. Typical install scenarios include through-rod assemblies, custom support structures, and framing builds where consistent diameter and surface finish are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCold rolled construction provides higher yield strength and hardness compared to hot rolled steel\u003c\/li\u003e\n\u003cli\u003eTighter dimensional specification ensures consistent 0.625-inch diameter along the full 48-inch length\u003c\/li\u003e\n\u003cli\u003eExcellent forming and welding characteristics for field fabrication\u003c\/li\u003e\n\u003cli\u003eRated for exterior applications\u003c\/li\u003e\n\u003cli\u003eMeets ASTM A510 standard for cold rolled steel rod\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose cold rolled smooth rod for fencing, railing, sign post, support, and framework applications where a 0.625-inch diameter, 48-inch steel rod is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by contractors, fabricators, or experienced tradespeople using standard metalworking tools including hacksaws, angle grinders, or cut-off wheels for sizing. Welding should follow standard MIG or stick procedures appropriate for cold rolled steel. Shut down any powered equipment in the work area before fitting or securing the rod. Follow applicable local building codes and ASTM specifications when using this rod in structural or load-bearing assemblies.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cold Rolled Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.17 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A510\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Exterior\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NATIONAL MFG\/SPECTRUM BRANDS HHI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N301-218\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL HARDWARE","offers":[{"title":"Default Title","offer_id":51560282128690,"sku":"N301-218","price":23.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28fafc1660e9638db09750fbbb75f2b8_0e73faf9-d5b3-4212-a7ab-1502fd7dff8a.jpg?v=1786450090","url":"https:\/\/voomisupply.com\/products\/national-mfg-n301-218-smooth-rod-0-625-x-48-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
