Q-Shape Stainless Steel Support Profile
Short Description:
Q-Shape Stainless Steel Support Profile is a shaped structural support wire used in welded wedge wire screens, filter cylinders and Johnson-type screen assemblies. It is positioned beneath the wedge-shaped surface wires to provide welding contact, structural rigidity and load support. SAKY STEEL supplies Q-shaped support profiles in 304, 316 and other stainless steel grades according to customer drawings, cross-sectional dimensions and screen requirements.
Q-Shape Stainless Steel Support Profile Overview
Q-Shape Stainless Steel Support Profile is a shaped structural support wire used in welded wedge wire screens, filter cylinders, screen panels and Johnson-type screen assemblies.
Unlike the wedge-shaped surface profile that forms the filtration slot, the Q-shaped support profile is positioned beneath or behind the working wires. Its main function is to provide welding contact, maintain screen geometry and support mechanical loads within the finished screen structure.
SAKY STEEL supplies Q-shaped stainless steel support profiles in grades such as 304 and 316. Cross-sectional width, height, curved section, tolerance, straightness and length can be reviewed according to customer drawings and screen-manufacturing requirements.

Function of Q-Shape Support Profiles
In a welded wedge wire screen, surface profile wires form the filtration openings while support profiles provide the structural framework. The support profiles are normally arranged perpendicular to the working wires and joined at their intersections.
| Function | Purpose |
|---|---|
| Structural Support | Supports the surface profile wires and contributes to overall screen rigidity. |
| Welding Contact | Provides a defined contact area for welding to wedge-shaped working wires. |
| Load Distribution | Helps distribute operating loads through the welded screen structure. |
| Screen Stability | Helps maintain wire spacing, screen shape and structural integrity during service. |
Surface Profile Wire vs Q-Shape Support Profile
| Feature | Surface Profile Wire | Q-Shape Support Profile |
|---|---|---|
| Main Function | Forms the filtration or screening surface | Provides structural support |
| Typical Position | Working side of the screen | Behind or beneath the surface wire |
| Design Priority | Slot width, flow and anti-clogging performance | Strength, welding area and structural rigidity |
| Cross Section | Usually wedge / V-shaped | Q-shaped support section |
Q-Shape Support Profile Dimensions
Q-shaped support profiles should be produced according to the required screen design or approved cross-sectional drawing. Width, height, curved geometry and welding surface dimensions can affect the finished screen strength and welding performance.
| Profile Parameter | Description |
|---|---|
| Profile Width | Overall width of the Q-shaped section |
| Profile Height | Overall section height |
| Welding Surface | Contact area used for joining with the surface profile wire |
| Curved Section | Radius or curved geometry according to drawing |
| Length | Straight or cut length according to screen fabrication requirements |
| Tolerance | Critical dimensions should be defined on the approved drawing |
Q-profile naming and dimensional systems may vary between screen manufacturers. Final production dimensions should therefore follow the specified profile drawing or agreed reference.
304 vs 316 Q-Shape Stainless Steel Support Profile
| Grade | Material Characteristic | Typical Selection |
|---|---|---|
| 304 | Good general corrosion resistance and practical material cost | General industrial screens, filtration and water applications |
| 316 | Improved resistance to chloride-containing and more aggressive environments | Water treatment, chemical service, marine and demanding wet environments |
Support Profile Options for Wedge Wire Screens
Different support profile geometries can be selected according to screen load, welding configuration and finished screen design. In addition to Q-shaped profiles, support members may use other shaped or solid sections.
| Q-Shape Profile Custom shaped support section | D-Type Profile Rounded support profile | V-Profile Wedge-shaped support wire |
| Square Rod Solid square support section | Flat Bar Flat support member for screen panels | Custom Profile Produced according to customer drawing |
Q-Shape Support Profile Manufacturing
Q-shaped support profiles are produced from stainless steel feedstock using controlled profile-forming processes. The processing route is selected according to material grade, section size, dimensional tolerance and finished screen requirements.
For support profiles used in automated screen welding, consistent section geometry and straightness are important for stable wire positioning and repeatable welded intersections.

Q-Shape Support Profile Packaging
Stainless steel support profiles are packed according to profile dimensions, unit length, surface condition, bundle weight and transportation requirements. Protective packaging helps reduce surface damage and profile deformation during handling and international shipment.
Packaging can be adapted to profile shape, dimensions, unit weight and shipping method.
Frequently Asked Questions
What is a Q-shape support profile?
A Q-shape support profile is a shaped structural member used beneath surface wires in welded wedge wire screens. It supports the working profiles and contributes to the strength of the finished screen.
Is Q-shape support wire the same as wedge surface wire?
No. The surface wire forms the filtration slot, while the Q-shaped profile acts primarily as a structural support member.
Can Q-shaped support profiles be customized?
Yes. Width, height, curved geometry, welding surface, tolerance and length can be reviewed according to the required cross-sectional drawing.
What stainless steel grades are available?
304 and 316 are common selections. Other stainless steel grades can be reviewed according to corrosion conditions, strength requirements and production feasibility.
What information is most important for a custom Q profile?
The most useful information is a cross-sectional drawing showing profile width, height, curved geometry, welding surface and dimensional tolerances.
