Innovative Stepped Structure for Multi-Scenario Adaptation​ The rubber sheet adopts a stepped design (with varying thicknesses at different sections), which perfectly fits suction cup bases of non-uniform inner structures. This design eliminates gaps between the rubber and the suction cup frame, ensuring tighter integration—solving the problem of poor sealing caused by mismatched flat rubber sheets in complex suction cup assemblies.​ Built-in Iron Strip for Enhanced Structural Stability​ A high-strength iron strip is embedded in the core layer of the rubber sheet, significantly improving the overall rigidity and shape retention of the product. Unlike ordinary suction cup rubber that easily bends or deforms during installation or use, this design ensures the stepped structure maintains its original form, avoiding adsorption failure due to structural collapse.​ Dual Enhancement of Adsorption & Load-Bearing Capacity​ The combination of the stepped rubber’s tight sealing and the iron strip’s load-bearing support creates a dual advantage: the rubber’s elastic material ensures airtight contact with smooth surfaces (reducing air leakage), while the iron strip distributes the weight of attached items evenly—allowing the suction cup to bear heavier loads (compared to non-iron-strip models) without slipping or detaching.​ Easy Installation & Positioning Accuracy​ The rigid iron strip inside the stepped rubber provides clear structural guidance during assembly, helping users align the rubber sheet with the suction cup base quickly. This not only simplifies the installation process (no need for repeated adjustments) but also ensures consistent positioning accuracy, reducing assembly errors for batch production or replacement.

Product Advantages and Features

  1. Embedded Iron Strip for Rigidity Enhancement

A high-strength iron strip (with thickness customizable according to load requirements) is embedded in the middle layer of the stepped rubber. This design significantly improves the product’s overall rigidity and anti-deformation ability—unlike ordinary flexible rubber sheets, it maintains the stepped shape stably during installation and use, preventing structural collapse caused by external pressure or frequent adsorption-release cycles.


  1. Precision Stepped Structure with Fixed Dimensions

With standard dimensions of 160mm (length) × 115mm (width) × 17mm (total thickness), the rubber sheet features a multi-section stepped design (thickness varies by section as per suction cup assembly needs). The dimensional tolerance is strictly controlled within ±0.5mm, ensuring it perfectly fits the inner cavity of matching suction cup bases, avoiding gaps that affect sealing performance.


  1. Dual Optimization of Sealing & Load-Bearing

The stepped rubber’s multi-section structure fits the suction cup’s inner contour tightly, maximizing airtight contact with smooth surfaces (e.g., glass, metal) to minimize air leakage and enhance adsorption stability. Meanwhile, the embedded iron strip evenly distributes the weight of bearing items (suitable for medium-load scenarios), increasing the suction cup’s maximum load capacity by 30% compared to models without iron strips.


  1. Wide Compatibility with Medium-Size Suction Cups

The 16011517mm size and stepped design are tailored for medium-size suction cup assemblies (commonly used in light industrial handling, large household storage, and commercial display equipment). It is compatible with suction cup bases with inner diameters of 80-120mm, and can be further customized in iron strip specifications to adapt to different load and structural requirements of specific scenarios.


  1. Easy Alignment & Efficient Installation

The rigid iron strip inside provides clear structural positioning during assembly—users can quickly align the stepped rubber with the suction cup’s mounting slots without repeated adjustments. This not only reduces installation time (improving assembly efficiency by 20% for batch operations) but also ensures consistent installation quality, avoiding performance differences caused by misalignment.


  1. Strong Material Bonding & Durability

The rubber material (selected for wear resistance and aging resistance) is bonded to the anti-rust iron strip (surface treated with galvanization or epoxy coating) via high-temperature pressing. This ensures no delamination between rubber and iron strip even in humid environments or after long-term use, extending the product’s service life to over 2.5 years under normal conditions.

Product Application Scope

  1. Industrial Heavy-Duty Material Handling
    It is widely used in automated workshops (such as steel processing, glass deep processing) for adsorbing and transferring large, heavy flat workpieces, including thick steel plates, oversized glass panels, and heavy plastic sheets. The trapezoidal structure fits the edge contours of irregular workpieces better, while the built-in iron strip enhances structural rigidity—preventing the rubber sheet from deforming under the weight of heavy objects (usually 8-15kg), ensuring stable and non-slip transfer during handling.
  2. Construction & Decoration Installation
    Applied to the on-site installation of large decorative materials, such as the adsorption and positioning of large ceramic tiles, marble slabs, and integrated ceiling panels. The 160mm×115mm large contact area ensures firm adsorption on the smooth surface of decorative materials, and the iron strip provides sufficient support to avoid bending or falling of the rubber sheet when lifting materials. It is especially suitable for high-altitude installation operations that require no drilling or damage to materials.
  3. Logistics & Warehousing Palletizing
    Used in manual or semi-automated palletizing systems to adsorb and stack large packaged goods, such as cartons for home appliances, plastic crates for industrial parts, and corrugated boxes for furniture. The trapezoidal design can adapt to the corner positions of rectangular packages, and the iron strip strengthens the load-bearing capacity—allowing the rubber sheet to maintain shape when bearing the weight of stacked goods, improving the efficiency of warehousing sorting and loading/unloading.
  4. Automotive Maintenance & Body Repair
    Applied to the disassembly and installation of large auto parts, such as car door panels, windshield glass, and roof covers. The soft silicone material of the suction cup rubber sheet avoids scratching the paint or surface of auto parts, while the iron strip ensures that the rubber sheet does not deform when pulling or positioning parts. It is a common auxiliary tool in auto repair shops for non-destructive handling of large body components.
  5. Exhibition & Display Setup
    Used in the installation of large exhibition boards, billboards, and display panels in exhibition halls, shopping malls, or event venues. It can adsorb on smooth surfaces (such as aluminum alloy frames, glass display cabinets) to fix large-sized display materials. The trapezoidal structure fits the edge gaps of display frames, and the iron strip provides stable support—preventing the display materials from tilting or falling due to external forces (such as crowd touching, air flow).
