National Mfg N316-489 Plain Steel Rebar Grade 4 36 Inches

Product Description

The NATIONAL MFG N316-489 is a plain steel rebar measuring 0.5 inches in diameter and 36 inches in length, rated Grade 4 and manufactured to ASTM A615-14 standards. It is designed for use in foundation construction, concrete forms, and post reinforcement applications where code-compliant, structural-grade steel reinforcement is required. This rebar provides tensile reinforcement within poured concrete assemblies. Installation is performed by concrete contractors, general contractors, and skilled tradespeople working on residential and light commercial structural projects. The package includes 3 pieces and ships at a combined weight of 10 pounds.

This rebar is suited for residential and light commercial concrete work including foundation walls, footings, concrete forms, and post bases. The 36-inch length makes it practical for column or post reinforcement inserts, tie-in sections, and short-span foundation pours. The plain surface finish is appropriate for applications where deformed rebar is not required by the project specification. Installers working under IBC or ACI 318 guidelines will find this rebar meets ASTM A615-14 Grade 4 requirements for structural concrete reinforcement.

Installation Notes

Installation is typically performed by concrete contractors or general tradespeople familiar with reinforced concrete work. Power tools and concrete forming equipment should be shut down and secured before placing rebar assemblies. Follow applicable building code requirements, including ACI 318 and local IBC provisions, for minimum cover, spacing, and lap splice lengths. Do not substitute plain rebar for deformed rebar in applications where deformed bar is specified by the structural drawings.
