The perforated, hammered sheet tin that make these lower cabinets so attractive is not old but actually brand new. Rubbed down with muriatic acid, these panels have “aged” in look if not in substance, and now they recapture the distant look of cabinetry from an earlier era.

Kingdom of Persia (now IRAN) specimen (perforated in the middle on the bottom) banknotes, designed to be payable in Teheran only, 1890-1923. Notes presented here, because they are very rare, especially in this UNC or almost UNC condition, and therefore very expensive (prices in thousands USD for each note). Photo set 1: one to twenty TOMANS (=name of the currency).

1. Filter Elements:

Perforated metal sheets are often used as the base material for filter elements. These sheets can be perforated with precise hole sizes and patterns to suit specific filtration requirements, such as particle size retention and flow rate. The perforated metal acts as a support structure for filter media, providing mechanical strength and stability.

2. Strainer Baskets:

Perforated metal is commonly used to fabricate strainer baskets or screens used in industrial filtration systems. These baskets prevent solid particles or debris from entering pipelines or equipment while allowing fluids to pass through. The perforated metal screens can be easily cleaned or replaced as needed, ensuring optimal filtration performance.

3. Air Filtration:

In HVAC systems and air purification units, perforated metal sheets are employed as the outer casing or housing for air filters. These perforated housings protect the filter media from damage while allowing air to pass through for filtration. Additionally, perforated metal can be used as pre-filters to remove large particles or contaminants before air passes through finer filter media.

4. Liquid Filtration:

Perforated metal is utilized in liquid filtration applications, such as water treatment plants, oil refineries, and chemical processing facilities. Perforated metal screens or tubes are integrated into filtration equipment to remove impurities, sediment, or solids from liquids. The perforated design allows for efficient filtration while minimizing pressure drop and maximizing flow rates.

5. Vibrating Screens:

Perforated metal sheets are employed in vibrating screens used for solid-liquid separation or particle classification processes. These screens consist of perforated metal panels tensioned over a vibrating frame. The perforations facilitate the passage of liquid or particles through the screen, while oversized materials are retained for further processing.

6. Food and Beverage Filtration:

In the food and beverage industry, perforated metal is utilized in filtration equipment for processing liquids, such as juices, syrups, and dairy products. Perforated metal screens or baskets are used to remove solids, pulp, or debris from raw materials or during the production process, ensuring product quality and purity.

7. Gas Filtration:

Perforated metal is employed in gas filtration systems to remove particulate matter, dust, or contaminants from gases or air streams. Perforated metal tubes or cylinders are often used as support structures for filter cartridges or as outer casings for gas filter housings.

I've put them by denominations to show the differences of various sets, that exist on the market. Mostly they are: various crowns in various places of the notes + various reverses + various serial ## + perforated word MINTA (=> SPECIMEN), as it is shown below:
