Stainless Steel Support Rods (Structural Support Bars)

Tianjin Jingzhou Metal Products manufactures high-strength Stainless Steel Support Rods, the essential internal structural component for wedge wire screens and Johnson screens. These rods act as the "backbone," providing the necessary rigidity and load-bearing capacity for the surface profile wires (Triangle, T-shape, or House-shape) during the fusion welding process.
· Structural Integrity: Designed to withstand high differential pressures and heavy mechanical loads.
· Precision Tolerance: Critical dimensions maintained at +/- 0.01mm for perfect welding alignment.
· Multiple Profiles: Available in round, triangular, or flat shapes to suit various screen designs.
· High Weldability: Optimized surface for consistent fusion welding points and structural stability.

Product Overview

Support Rods (also known as support bars) are the foundational elements located internally in a wedge wire screen. While the surface wire determines the filtration precision, the support rod determines the screen’s overall strength and durability. Our support rods are cold-drawn using premium stainless steel alloys to ensure high tensile strength and a clean surface. The precise geometry of our rods ensures that the surface wire can be wound and welded at exact intervals, maintaining uniform slot openings even under extreme industrial stress.

Key Advantages

Enhanced Load-Bearing: Engineered to prevent screen collapse or deformation in deep-well or high-pressure filtration scenarios.
Perfect Welding Alignment: The +/- 0.01mm tolerance ensures a 100% contact rate with the surface wire, creating a stronger fusion weld.
Corrosion Resistance: Using high-grade SS316L ensures the internal skeleton of the screen does not fail in acidic or saltwater environments.
Optimized Flow Dynamics: Available in shapes like the “tear-drop” or “triangular” to minimize turbulence and flow resistance inside the screen.

Industrial Applications

Beer and Beverage: High-precision V-wire and T-wire components provide the ideal self-cleaning surface for lauter tun false bottoms and diatomaceous earth filters in brewing.
Mining Screen: Heavy-duty house-shaped and triangle wires offer superior wear resistance and high-impact structural stability for coal washing and ore dewatering.
Oil and Gas: Precision-engineered wedge wire profiles ensure efficient sand control and catalyst recovery in high-pressure downhole and refinery environments.
Paper and Pulp Filter: Non-clogging wedge wire cylinders and support rods facilitate high-efficiency fiber recovery and white water recycling in paper manufacturing.
Powder Screen Filter: Ultra-fine slot openings (down to 0.02mm) allow for the precise dry or wet classification of fine powders and chemical granules.
Water Treatment: Robust support rods and profile wires act as the backbone for intake screens and resin traps, ensuring long-term reliability in municipal filtration.

FAQ

Q: Can the support rod be a different shape than the surface wire?
A: Yes. For example, it is very common to use a Triangle Wire for the surface and a Round Rod or Flat Bar for the support to achieve a balance between filtration efficiency and structural cost.
A: We often recommend larger profiles like 3.8mm/22 or customized flat bars (e.g., 2x3mm or 3x5mm) to handle high-impact loads and vibration.
A: We provide both. Straight lengths are ideal for flat screen panels, while coils are typically used for continuous-wound cylindrical screen production.
A: If the support rod diameter varies, the welding points will be inconsistent, leading to uneven slot gaps in the screen. Our +/- 0.01mm tolerance eliminates this risk, ensuring a perfect filter every time.
