Multiple Production Methods
Available as True Mill Flat Bars with precise tolerances and smooth finish, or Sheared Flat Bars cut from plates for flexible sizing and quick turnaround. We also offer Cold Drawn Flat Bars with enhanced mechanical properties. -
High Dimensional Accuracy
True mill bars offer uniform surface quality and sharper edges across all four sides, ideal for applications requiring minimal twist and high surface consistency. -
Excellent Strength & Corrosion Resistance
Manufactured from stainless steel grades such as 304, 316L, and others, flat bars provide strong resistance to corrosion, impact, and high stress. -
Versatile Sizing & Customization
Widths, thicknesses, and lengths are customizable. We offer bars up to 20 feet with various surface finishes (2B, HL, #1 HRAP, 180# and higher) to meet your exact project needs. -
Adaptable to Structural and Decorative Uses
Whether used for support frames, brackets, construction components, or architectural detailing, flat bars deliver both strength and clean visual lines. -
Factory-Direct Supply with Quality Assurance
All flat bars are produced under strict quality control systems and conform to ASTM A276, A479, and A484 standards, ensuring consistency and reliability from raw material to delivery.
-
Structural Supports
Widely used in construction frameworks, base plates, and reinforcement structures for their strength and stability. -
Machinery & Equipment Components
Applied in manufacturing equipment, brackets, and mechanical assemblies requiring flat and durable profiles. -
Architectural & Decorative Projects
Ideal for staircases, railings, facades, and interior trims, offering both strength and a sleek appearance. -
Automotive & Transportation
Used in trailer frames, chassis parts, and bus body structures for their lightweight yet strong characteristics. -
Fabrication & Welding Projects
Preferred in metal fabrication shops for ease of cutting, bending, and welding, suitable for custom structures. -
Furniture & Fixtures
Incorporated in modern furniture designs, table bases, and shelving units due to their clean lines and corrosion resistance.
| Comparison Items | 200 Series (201) | 300 Series (304 as a representative) | 400 Series (430 as a representative) |
|---|---|---|---|
| Chemical Composition | Chromium (Cr) 16% – 18%, manganese (Mn) 5.5% – 7.5%, nickel (Ni) 3.5% – 5.5%, nitrogen (N) ≤0.25% | Chromium (Cr) 18% – 20%, nickel (Ni) 8% – 10.5%, low carbon | Chromium (Cr) 16% – 18%, low carbon, ferrite structure |
| Tensile Strength (MPa) | ≥520 | ≥515 | ≥450 |
| Elongation (%) | ≥40 | ≥40 | ≥22 |
| Corrosion Resistance | Moderate corrosion resistance, suitable for less corrosive environments. Prone to rusting in humid or corrosive conditions compared to 300 series. | Good general corrosion resistance, suitable for general atmosphere, fresh water and other environments, relatively weak tolerance to chloride ions | Fair corrosion resistance, better than carbon steel but inferior to 300 series. Susceptible to pitting corrosion in chloride-rich environments. |
| Magnetic Properties | Weakly magnetic due to its alloy composition | Non-magnetic in the annealed state, may become slightly magnetic under certain processing conditions | Magnetic |
| Cost | Relatively low, due to lower nickel content and relatively simple composition | Moderate, as a widely used and reliable grade | Relatively low, similar to 200 series in terms of cost, but with different performance characteristics |
| Application Fields | Interior decoration, low-end kitchenware, some decorative trims in buildings where corrosion resistance requirements are not high | Kitchen utensils, building decoration, general industrial components and other daily fields | Appliance housings, automotive trim, some food processing equipment where non-magnetic properties are not required and moderate corrosion resistance suffices |
