Premium Stainless Steel Flat Bars (Grades 304 & 316L) for Industry & Architecture
Stainless Steel Flat Bars (Flat Bars) are highly versatile solid bars with a rectangular cross-section. Known for their high structural strength, resistance to torsional forces, and excellent anti-rust properties, they are widely used in machine frames, industrial platforms, heavy machinery, and architectural designs.
Slit Edge vs. Hot Rolled (True Bar): Which is Best for Your Project?
Understanding the difference in manufacturing processes helps you balance procurement costs with engineering requirements:
| Features | Slit Edge (Sheared Bar) | Hot Rolled (True Bar) |
|---|---|---|
| Manufacturing | Cut and sheared from stainless steel coils. | Hot rolled directly from billets into a flat shape. |
| Edge Profile | Sharp, 90-degree edges (may require deburring). | Smooth, slightly rounded, and aesthetically pleasing edges. |
| Straightness | Moderate (slight bowing may occur). | Excellent (perfectly straight). |
| Cost | Highly Economical. | Premium Pricing. |
| Best For | General frames, bending, and hidden structural supports. | Exposed edges, architectural trims, and precision machining. |

Common Applications
- Architectural Fabrications: Supporting columns, beams, high-end fences, automatic gate structures, balustrades, and handrails.
- Food Machinery (Food Grade): Structural frames and heavy load-bearing brackets in food and pharmaceutical processing machinery.
- Interior Fittings: Brushed Hairline (HL) flat bars used for modern loft-style furniture frames, mirrors, and premium cabinetry trims.
- Marine Engineering: Trawler parts, offshore platforms, and coastal equipment (Grade 316L is highly recommended to resist saltwater corrosion).
Frequently Asked Questions (FAQ)
The main differences are edge profile and straightness. Slit Edge bars (Sheared) are cut from coils; they have sharp 90-degree edges and may show slight bowing, but are highly cost-effective for general structural use. Hot Rolled bars (True Bar) are rolled directly from billets; they feature perfectly straight lines, slightly rounded smooth corners, and are ideal for exposed architectural elements and precision machining.
We stock standard 6-meter bars in widths ranging from 1/2" (12.7 mm) to 6" (152.4 mm), and thicknesses from 1/8" (3.0 mm) up to a heavy 1" (25.4 mm). Milimeter-spec sizes are also available. Please refer to our weight chart or contact our sales team to check real-time stock.
Yes, we do! If your project requires custom lengths to eliminate on-site labor and material scrap, you can specify your required dimensions to our sales team. We provide professional bandsaw cutting to ensure clean, accurate lengths ready for immediate fabrication.
Absolutely. While the standard delivery finish is No.1 (matte grey), we provide professional surface brushing to a Hairline (HL) finish upon request. This is highly popular for premium interior designs, furniture bases, and architectural trims.
For general structures, indoor handrails, and architectural furniture, Grade 304 is the most cost-effective and highly durable standard. However, if the material is used in food processing machinery handling acids, chemical tanks, or marine equipment exposed to saltwater, Grade 316L is mandatory to prevent pitting and corrosion.
Yes, every batch of our stainless steel flat bars is supplied with a Mill Test Certificate (MTC) in accordance with ASTM A276/A484. Combined with our professional logistics fleet, we offer secure and fast nationwide transportation directly to your factory or project site across Thailand.
