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 - STEEL BAR CONSTRUCTION: This 3 in x 36 in flat steel bar delivers exceptional durability with hot-rolled plain steel construction, perfect for reinforcement applications, base plates, and structural supports in construction projects. - METAL SPECIFICATIONS: Hot-rolled steel flat bar meets ASTM A1011 specification standards, providing reliable performance for industrial applications with excellent forming and welding characteristics for custom fabrication needs. - DIMENSIONS: Steel flat bar measures 3 in wide by 36 in long, offering versatile sizing for construction reinforcement, bracket manufacturing, and structural support applications in both residential and commercial projects. - APPLICATIONS: Flat steel bar excels in exterior construction applications, providing robust metal reinforcement for base plates, structural supports, brackets, and custom fabrication projects requiring durable steel materials. - FABRICATION: Plain steel construction allows easy welding, forming, and machining without oil treatment interference, making this metal flat bar ideal for custom construction and industrial manufacturing applications. - 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 | B0027E1PQA | | Best Sellers Rank | #27,610 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #460 in Hardware Brackets | | Brand | National Hardware | | Brand Name | National Hardware | | Color | Plain Steel | | Customer Reviews | 4.6 out of 5 stars 682 Reviews | | Global Trade Identification Number | 00038613301375 | | Grade Rating | Grade 8 | | Included Components | Hardware;Door, Gate & Window Hardware;screen-door-hardware | | Item Diameter | 3 Inches | | Item Dimensions | 35.98 x 2.99 x 2.99 inches | | Item Form | Flat | | Item Shape | Flat | | Item Thickness | 3 Inches | | Item Type Name | Stanley National Hardware N301-374 4062BC Solid Flat in Plain Steel, 3" x 36" | | Item Weight | 5.9 Ounces | | Item dimensions L x W x H | 35.98 x 2.99 x 2.99 inches | | Manufacturer | National Hardware | | Material | Metal | | Model Number | N301-374 | | Number of Items | 1 | | Part Number | N301374 | | Shape | Flat | | Specification Met | Astm A1011 | | UPC | 038613301375 | | Unit Count | 1.0 Count | ## Images ![National Hardware N301-374 4062BC Solid Steel Flat Bar 3 in x 36 in Plain Hot-Rolled Metal for Construction Industrial Reinforcement Base Plates Supports ASTM A1011 - Image 1](https://m.media-amazon.com/images/I/41icMWp8u1L.jpg) ![National Hardware N301-374 4062BC Solid Steel Flat Bar 3 in x 36 in Plain Hot-Rolled Metal for Construction Industrial Reinforcement Base Plates Supports ASTM A1011 - Image 2](https://m.media-amazon.com/images/I/517gupa+9ZL.jpg) ![National Hardware N301-374 4062BC Solid Steel Flat Bar 3 in x 36 in Plain Hot-Rolled Metal 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. ## Questions & Answers **Q: is this 3/16 thick. >>.1875 ?** A: Yes **Q: what's it's ksi strength?** A: lbs **Q: What is the actual weight of each 3"x36" piece? The description says "5.9 ounces" should it be "5.9 lbs"?** A: Sam. Steel weight 0.2833 #s per cu in. So 36*3*0.125*.2833=3.8 lbs **Q: Is this blade steel?** A: Dude, this is not knife blade quality steel. If that's what you're looking for, search for "blade blanks" and then keep an eye out for decent materials like: Damascus steel, D2 Steel, 8Cr13mov is another good steel. Not as good as Sandvik 12C27 steel, but good enough... 440c and 420hc are both very good materials as well! I wish you luck! ## 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.
