The expanded pattern features a 3\/4 inch grid opening, providing a sturdy open-mesh structure suitable for ventilation, guarding, screening, and structural reinforcement applications. Because this material is plain steel with no protective coating applied at the factory, it must be primed, painted, powder coated, or otherwise treated before installation in any environment where moisture exposure is a concern. Fabricators, contractors, and maintenance technicians working in HVAC, industrial, or general construction settings commonly use this material for custom enclosures, grille work, and protective barriers.\u003c\/p\u003e\u003cp\u003eThis expanded sheet metal panel is suited for trade and industrial applications requiring a rigid, open-mesh steel blank that can be cut, bent, or fastened to fit a specific installation. Typical uses include equipment guards, ventilation panels, drainage grates, filter frames, and architectural infill panels. The 13 gauge hot rolled plain steel construction delivers solid rigidity in a manageable sheet size. Each package contains 3 panels, making it practical for jobs requiring multiple pieces or allowing for cut-to-fit customization on-site.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e12 inches by 16 inches sheet size — ready to cut or install as-is\u003c\/li\u003e\n\u003cli\u003e13 gauge hot rolled plain steel construction for rigid, durable performance\u003c\/li\u003e\n\u003cli\u003e3\/4 inch expanded grid pattern for open-mesh ventilation or guarding\u003c\/li\u003e\n\u003cli\u003ePlain steel finish — must be protected to prevent corrosion before or after installation\u003c\/li\u003e\n\u003cli\u003eSold in a package of 3 panels per unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose expanded sheet metal blank suitable for custom fabrication, equipment guarding, ventilation, and screening applications across HVAC, plumbing, electrical, and general construction trades.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of expanded sheet metal panels is typically performed by fabricators, maintenance technicians, or general contractors using standard metal-cutting and fastening tools. Always wear cut-resistant gloves and eye protection when handling or cutting expanded metal — edges and cut ends are sharp. Apply an appropriate corrosion-resistant primer, paint, or coating before installation in any wet, outdoor, or high-humidity environment, as the plain steel surface has no factory corrosion protection. Follow all applicable local building and safety codes when using expanded metal in guarding or structural applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Rolled Plain Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSheet Dimensions\u003c\/strong\u003e: 12 inches x 16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGauge\u003c\/strong\u003e: 13 GA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrid Opening\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction Type\u003c\/strong\u003e: Expanded Sheet Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 3 panels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.99 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion Protection\u003c\/strong\u003e: None applied — must be protected to prevent corrosion\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: N301-598\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL HARDWARE","offers":[{"title":"Default Title","offer_id":51559098843442,"sku":"N301-598","price":41.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/10b16b7cf183464c3fa057b9e6147f01_9d9967c1-5680-46a4-b5a6-430d37d7842e.jpg?v=1786427513","url":"https:\/\/voomisupply.com\/products\/national-mfg-n301-598-expanded-sheet-metal-12x16-13ga","provider":"Voomi Supply","version":"1.0","type":"link"}
