Rectangular Stainless Steel Profile Wire
Short Description:
Rectangular Stainless Steel Profile Wire is a precision-shaped wire with controlled width, thickness, edge geometry and dimensional tolerance for filtration, springs, sealing components, mechanical assemblies and precision industrial applications. SAKY STEEL supplies rectangular profile wire in 304, 316, 316L and other stainless steel grades with custom dimensions, corner radius, surface condition and coil or straight-length delivery according to customer drawings.
Rectangular Stainless Steel Profile Wire Overview
Rectangular Stainless Steel Profile Wire is a precision-shaped stainless steel wire with controlled width, thickness and edge geometry. Compared with conventional round wire, the rectangular cross section provides a larger flat contact surface and can be produced to suit specific assembly, filtration, spring, sealing and mechanical requirements.
SAKY STEEL supplies rectangular profile wire in 304, 316, 316L and other stainless steel grades. Width, thickness, corner radius, edge condition, dimensional tolerance, surface and delivery form can be customized according to customer drawings and application requirements.

Rectangular Profile Dimensions
Rectangular stainless steel wire is normally specified by width × thickness. For precision applications, corner radius, edge geometry and dimensional tolerance should also be defined.
| Profile Parameter | Description |
|---|---|
| Width | Overall width of the rectangular cross section |
| Thickness | Section thickness according to drawing or application |
| Corner Radius | Square, slightly rounded or specified radius according to design |
| Edge Condition | Controlled according to forming and application requirements |
| Length / Coil | Coil, spool, straight length or cut length according to feasibility |
| Tolerance | Critical dimensional tolerances according to approved drawing |
Rectangular Profile Wire vs Flat Wire
The terms rectangular wire and flat wire are sometimes used for similar products. For precision orders, the required cross-sectional geometry should be defined by dimensions and drawing rather than product name alone.
| Feature | Rectangular Profile Wire | Flat Wire |
|---|---|---|
| Cross Section | Defined rectangular width × thickness | Generally wide and relatively thin |
| Edge Geometry | Square or controlled-radius edges | May use rounded, natural or processed edges |
| Selection Priority | Cross-section accuracy and dimensional control | Width-to-thickness ratio and flat surface |
Custom Rectangular Stainless Steel Wire
Rectangular profile wire can be produced according to customer drawings when standard flat or round wire cannot provide the required cross section. Dimensions and tolerances are reviewed according to material grade, section ratio and production feasibility.
| Custom Section
Width and thickness according to drawing |
Edge Control
Corner radius and edge geometry |
Precision Tolerance
Critical dimensions according to drawing |
304 vs 316 Rectangular Stainless Steel Wire
| Grade | Main Characteristic | Typical Selection |
|---|---|---|
| 304 | Good general corrosion resistance and versatile forming performance | General industrial, mechanical and precision components |
| 316 / 316L | Improved resistance in chloride-containing and more corrosive environments | Marine, chemical, filtration and demanding wet-service applications |
Rectangular Profile Wire Manufacturing
The production route is selected according to stainless steel grade, width-to-thickness ratio, dimensional tolerance, surface condition and required delivery form.
Process control focuses on maintaining consistent width, thickness, edge geometry and surface condition along the finished profile.
Inspection & Quality Control
| Inspection Item | Purpose |
|---|---|
| Material Verification | Confirm stainless steel grade and material traceability |

Frequently Asked Questions
What is rectangular stainless steel profile wire?
It is stainless steel wire formed or drawn to a controlled rectangular cross section defined primarily by width and thickness.
What is the difference between rectangular wire and flat wire?
The terms can overlap, but rectangular profile wire usually emphasizes controlled cross-sectional geometry and dimensional tolerance. Flat wire is often used more broadly for relatively wide and thin wire products.
Can the width and thickness be customized?
Yes. Width, thickness, corner radius, edge condition and dimensional tolerances can be reviewed according to customer drawings and production feasibility.
Can rectangular profile wire be supplied in coils and straight lengths?
Yes. Depending on section dimensions and material condition, supply forms can include coils, spools, straight lengths and cut lengths.
Which stainless steel grades are commonly available?
304, 316 and 316L are common selections. Other stainless steel grades can be reviewed according to corrosion resistance, mechanical performance and forming requirements.
Can MTC and dimensional inspection records be supplied?
Yes. Material certificates and agreed dimensional inspection documentation can be supplied according to confirmed order requirements.
