Strudex tensioned rubber screen panels use welded steel hook edges to connect the rubber screening surface to the screen’s tensioning system. The panel is secured by pulling the hooks through the deck’s tension rails or tensioning devices, without installation bolts passing through the rubber body. This configuration combines a resilient working surface with a defined mechanical mounting interface for grading and mineral screening.

Strudex hook-edge rubber screen panels connect a resilient screening surface to external tensioning devices through welded steel hooks. The hooks are bonded to the rubber during vulcanization and transfer the retaining load at the edges, so installation bolts do not pass through the rubber body. Custom panel dimensions, openings, hardness and hook profiles allow the surface and its mechanical interface to be defined together.

| Panel dimensions | Customized |
| Aperture size and pattern | Customized |
| Rubber hardness and hook profile | Customized for the selected configuration |
The hook does more than provide a convenient handle at the panel edge. Its engagement with the tensioning system determines where the applied force enters the component. The rubber then follows its intended support profile as the assembly is drawn into its working condition. Hook cross-section, projection and orientation therefore belong to the functional product drawing alongside the aperture pattern and overall panel dimensions.
| Part of the hook-edge assembly | Contribution to the working panel |
|---|---|
| Rubber screening body | Provides a resilient surface and the section around the openings. Its compound and geometry influence response to impact, sliding contact and lodged particles. |
| Vulcanized hook connection | Joins the edge hardware to the rubber body. This connection should be defined as part of the ordered component rather than treated as unrelated installation hardware. |
| Mating tensioning device | Applies and retains the force through the hook. Correct engagement establishes the intended contact instead of relying on a small lip or partial catch. |
| Deck support profile | Supports the tensioned surface at its intended locations. Its contour and protective contact surfaces influence how the rubber behaves between the retained edges. |
This design separates the mounting connection from through-body installation holes. That can be useful where the screen is designed for tensioned media and the selected rubber section should remain intact at its working body. It does not make external rails or tensioning bolts unnecessary: those components still provide the force that locates the panel. The useful comparison is between complete mounting arrangements, each matched to its intended deck.
Strudex offers in-house rubber mixing and customization of the material response and finished panel geometry. The compound provides one part of the solution; thickness, webs, opening passage and supporting profile determine how it is used. A more flexible grade may assist release at an aperture, while the section still has to carry the expected contact. Neither rubber hardness nor a large nominal opening area independently describes the complete panel’s process performance.
| Duty to define | Design relationship to review |
|---|---|
| Impact from the feed | Relate the credible particle size, drop and contact location to the rubber section and support. A concentrated strike can create a different demand from distributed material at the same average rate. |
| Abrasive travel | Review the rubber at the opening edges and along material paths. The panel needs to retain the intended passage as the surface wears, not merely remain attached to the hooks. |
| Near-size or adhering material | Identify whether particles lodge individually or fines coat the surface. Aperture geometry, flexibility, moisture and material distribution contribute differently to those mechanisms. |
| Required product grading | Define acceptable passage and misplaced material before changing openings. Shape, orientation and thickness can affect how particles encounter the passage even when the nominal opening dimension is unchanged. |
A useful operating comparison combines the product streams with component condition. Openings that have enlarged can change the separation even while the hook edges remain secure. Conversely, movement at a support can damage a panel whose aperture design is otherwise suitable. Keeping these mechanisms distinct makes the next material or geometry decision more focused.
Specify the panel and hook drawings, support contour, tension direction, aperture pattern and rubber requirement with the feed and grading objectives. A matching hook-family listing can help identify the product type, but its example dimensions or hardness options should not be assumed to define every customized panel. The agreed configuration remains the basis for manufacture and acceptance.
