Review: Excellent steel and delivery - It is very rare that I ever write product reviews unless product/service is very good or very, very bad. This is a case of the product and service being very good. I ordered a 1"x36" flat bar which turns out to be 1/8" thick. Just what I wanted for my project. The steel is nice and straight, no rust or defects and came in a heavy duty 8x8x36 box to ensure that it would arrive unbent. FedEx delivered it just 3 days after I ordered it, on a Sunday. Excellent service and product. ## Features - CONSTRUCTION GRADE: This 1 in x 36 in steel flat bar delivers exceptional strength for reinforcement, base plates, and structural supports in demanding construction and industrial applications with superior durability. - MATERIAL COMPOSITION: Hot-rolled plain steel bar construction meets ASTM A1011 specifications, providing excellent forming and welding characteristics for professional fabrication projects requiring reliable metal bar performance. - DIMENSIONS SPECIFICATIONS: Measures precisely 1 inch width by 36 inch length with 3.5 x 2.5 x 38 inch packaging dimensions, offering versatile steel bar solutions for custom construction and manufacturing requirements. - EXTERIOR APPLICATIONS: Engineered specifically for outdoor use where weather resistance and structural integrity are essential, this steel flat bar withstands harsh environmental conditions while maintaining performance standards. - FABRICATION READY: Untreated plain steel bar surface allows easy welding, forming, and machining without oil interference, enabling seamless integration into custom projects requiring precision metal bar fabrication. - QUALITY: National Hardware brand ensures over a century of manufacturing excellence with color-coded labeling system for easy identification, backed by proven innovation and superior product standards. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002CU3FG2 | | Best Sellers Rank | #202,231 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #407 in Hardware Brackets #43,942 in Hardware | | Brand | National Hardware | | Brand Name | National Hardware | | Color | Plain Steel | | Customer Reviews | 4.6 out of 5 stars 680 Reviews | | EU Spare Part Availability Duration | 10 Years | | Global Trade Identification Number | 00038613301351 | | Grade Rating | Commercial | | Included Components | Hardware;Door, Gate & Window Hardware;screen-door-hardware | | Item Diameter | 1 Inches | | Item Dimensions | 38 x 3.5 x 2.5 inches | | Item Form | Flat | | Item Shape | Rectangular | | Item Type Name | Stanley National Hardware N301-358 4062BC Solid Flat in Plain Steel, 1" x 36" | | Item Weight | 1.2 Pounds | | Item dimensions L x W x H | 38 x 3.5 x 2.5 inches | | Manufacturer | National Hardware | | Material | Metal | | Model Number | N301-358 | | Number of Items | 1 | | Part Number | N301358 | | Shape | Rectangular | | Specification Met | True | | UPC | 038613301351 | | Unit Count | 1.0 Count | ## Product Details - **Material:** Metal - **Brand:** National Hardware - **Item dimensions L x W x H:** 36 x 1 x 0.12 inches - **Color:** Plain Steel - **Shape:** Rectangular ## Images ![National Hardware N301-358 4062BC Hot-Rolled Steel Flat Bar 1 in x 36 in Plain Metal Bar for Construction Industrial Reinforcement Base Plates Supports ASTM A1011 - Image 1](https://m.media-amazon.com/images/I/51E5npsAmgL.jpg) ![National Hardware N301-358 4062BC Hot-Rolled Steel Flat Bar 1 in x 36 in Plain Metal Bar for Construction Industrial Reinforcement Base Plates Supports ASTM A1011 - Image 2](https://m.media-amazon.com/images/I/51gyMLoX6ML.jpg) ![National Hardware N301-358 4062BC Hot-Rolled Steel Flat Bar 1 in x 36 in Plain Metal Bar for Construction Industrial Reinforcement Base Plates Supports ASTM A1011 - Image 3](https://m.media-amazon.com/images/I/71N6-5ioLfL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product! *by B***E on February 20, 2026* Great product and works great! ### ⭐⭐⭐⭐⭐ Excellent steel and delivery *by C***J on March 8, 2026* It is very rare that I ever write product reviews unless product/service is very good or very, very bad.
