Durable Wedge Wire Support Grates Engineered for Harsh Environments

Wedge wire screen support grid is made of stainless steel or nickle alloy, which mainly includes the wedge wire screen and frame. There are whole type and joint type support grids for choice. The whole type is often in small diameter and the large diameter grid is divided into several parts for easy transportation. Compared with woven wire mesh or perforated mesh, wedge wire is featured by the continuous slots. With high strength, perfect filtering performance and long service life, it is widely used for carbon filters and molecular sieves.

Key Advantages

Wedge Wire support grids offer a relatively flat and smooth surface to reduce degradation of the media  in down-flow processes.  The high open area of the Wedge Wire screen provides excellent capacity. 

Stainless steel wedge wire support grids can be designed for total load and operating temperature.The  all-welded stainless steel construction produces high strength and extended service life suitable for many screening applications in numerous industries. Support grids are used in carbon  filters, desulfurizers,  molecular sieves, sand filters, gas sweeteners and lauter tanks.

Wedge Wire screen offers continuous slot openings that widen inwardly so that particles tend to pass  through the screen. 

High strength and durability.

High open area and precise opening.

Perfect filtering property without clogging.

Corrosion and rust resistance.

High and low temperature resistance.

Smooth surface and long service life.

Applications

Catalyst bed support grid for petrochemical and refining industries

Wedge wire false bottom used in beer brewing

Reactor internals for carbon filters

Hydrogenation reactors

Desulfurization reactors

Mash tuns in the brewing industry

FAQ: Wedge Wire Screen Support Grids

1. How do I select the right support grid for my system?

Focus on vessel diameter, load requirements, media type, and operating temperature. Custom designs are often recommended to ensure proper fit and long-term stability.

2. Can support grids be customized for unique equipment?

Yes. Grids can be manufactured in segmented or one-piece designs, with tailored dimensions, slot sizes, and materials to match specific project requirements.

3. What factors affect the lifespan of a support grid?

Material selection, operating conditions (temperature, pressure), and media type all influence service life. Proper installation and routine inspection can significantly extend usage time.

4. Are wedge wire support grids suitable for high-temperature applications?

They are well-suited for both high and low temperature environments, especially when constructed from appropriate alloys designed for thermal stability.

5. What maintenance is typically required?

Most systems require only periodic inspection and occasional cleaning, depending on the process conditions and media being handled.

6. Can they handle uneven load distribution?

Yes. Properly engineered support grids are designed to evenly distribute loads, preventing media shifting and protecting downstream equipment.
