D-Type Stainless Steel Support Rod is a shaped support profile used in welded wedge wire screens, Johnson-type screen structures, filter cylinders and screen panels. Unlike the wedge-shaped surface wire that forms the filtering slot, the support rod is positioned behind the working wires to provide structural strength and maintain screen geometry.
SAKY STEEL supplies D-shaped stainless steel support rods according to customer drawings and screen-manufacturing requirements. Material grade, profile width, height, radius, tolerance and straight-length requirements can be customized according to the finished screen design.
Product: Stainless Steel Support Rod Profile: D-Type / D-Shaped Profile Common Grades: 304 / 316 / Other Agreed Grades Surface: Bright / Smooth / Customized Supply Form: Straight Length / Coil When Feasible Dimensions: According to Customer Drawing Application: Wedge Wire Screens / Johnson-Type Screens / Screen Cylinders
Request D-Type Support Rod QuoteIn a welded wedge wire screen, the surface profile wires create the filtration slots while the support rods run perpendicular to them. Each intersection is welded to form a rigid screen structure.
| Function | Purpose |
|---|---|
| Structural Support | Supports the wedge-shaped surface wires and helps the finished screen carry mechanical loads. |
| Welding Base | Provides the contact surface for resistance welding with the working profile wires. |
| Screen Stability | Helps maintain wire spacing, screen shape and structural rigidity. |
| Load Distribution | Transfers operating loads across the welded screen structure. |
| Feature | Wedge Surface Wire | D-Type Support Rod |
|---|---|---|
| Main Function | Forms the screening / filtration surface | Provides structural support |
| Typical Profile | V-shaped / wedge-shaped | D-shaped support profile |
| Position | Working surface of the screen | Behind / beneath the surface wire |
| Design Priority | Slot size, flow and anti-plugging performance | Rigidity, span and load capacity |
D-shaped support rods should be ordered according to the required cross-sectional geometry. For custom profiles, please provide a drawing with the critical dimensions and tolerances.
| Profile Parameter | Information to Specify |
|---|---|
| Profile Width | Overall section width |
| Profile Height | Overall section height |
| Flat Surface | Required flat-side dimension for welding contact |
| Rounded Section | Radius or curved-bottom geometry |
| Length | Required straight length or other delivery form |
| Tolerance | Critical dimensional tolerances according to screen design |
| Grade | Main Characteristic | Typical Selection |
|---|---|---|
| 304 | Good general corrosion resistance and economical material selection | General screening, industrial filtration and water applications |
| 316 | Improved corrosion resistance in chloride-containing and more aggressive environments | Water treatment, chemical processing and demanding wet-service screens |
| Inspection Item | Purpose |
|---|---|
| Material Verification | Confirm stainless steel grade and material traceability |
| Profile Dimensions | Verify width, height and D-shaped geometry |
| Straightness | Check straight-length condition for downstream screen welding |
| Surface Inspection | Check surface condition and visible defects |
| Documentation | MTC and dimensional inspection records as required |
| Wedge Wire Screens Structural support beneath working wires | Screen Cylinders Longitudinal support for cylindrical screens | Filter Elements Support profiles for welded filter structures |
| Water Well Screens Internal support for continuous-slot screens | Water Treatment Screen and filtration structures | Industrial Separation Structural support for screen assemblies |
D-type stainless steel support rods are packed according to profile dimensions, straight length, unit weight and transportation requirements.
A D-type support rod is a shaped structural profile used beneath wedge-shaped working wires in welded screen structures. Its main purpose is to support the surface wires and strengthen the finished screen.
No. Wedge wire forms the filtering surface and slot openings, while the support rod provides structural support behind the working wires.
Yes. Cross-sectional width, height, curved section, straight length and dimensional tolerance can be reviewed according to customer drawings.
Yes. Shaped support rods are used in welded wedge wire and continuous-slot screen constructions where they support the working profile wires.
