Perforated brass 

Perforated Brass — The Basics

Brass is a highly sought building material that has been used for generations. It is an alloy of copper and zinc, and the formula can be tweaked to enhance specific properties. Adjustments can be made to strengthen the material, increase hardness, improve corrosion resistance, and/or change the color, making it a very versatile metal alloy. Brass can be easily perforated in rows. A perforated brass sheet thus allows in limited light while still providing excellent ventilation. It also gives any structure an added element of depth.

At our company, we are experts in perforated metals, and we know how to work with brass to create the perfect panels for you.

The Benefits of Selecting Perforated Brass

Perforated brass sheet metal is one of the most visually impressive build materials, and it also is highly regarded for its strong corrosion-resistant properties. At Dongjie Company, we specialize in manufacturing perforated sheet metal panels for projects of all kinds. From brass to steel, we have perfected our products for use in countless industries. Brass perforated sheet metal is an ideal building material for both functional and aesthetic purposes, and we can supply the perfect material for any application.

Applications for Perforated Brass

Perforated brass can be used in a great variety of applications. It is slightly more malleable than many materials. While it’s strong, it might not be ideal as a weight-bearing material. Its gold-like appearance makes it more aesthetically appealing than many materials, making it perfect for decorative applications, such as building facades. Perforated brass is an excellent option for providing privacy screening or shading. It also is useful for controlling sound while allowing the ideal amount of airflow.

The experts at our company understand the ins and outs of perforated brass, including its strengths and weaknesses. Our team can help you with your project by helping you find the perfect building material.

Perforated galvanized 

The beauty of perforated metal is that its indoor and outdoor applications are seemingly endless. Perforated galvanized steel, also known as perforated galvanized metal, is an ideal material for tough environments because it holds up against corrosion and it’s economical. At our company, we specialize in a wide range of perforated metal materials, including perforated galvanized steel sheet metal.

Each kind of metal we perforate has unique benefits. For galvanized steel, it’s strength and resistance to corrosion. Steel by itself is an excellent building material because of its capacity for strength. Yet if it is not galvanized, steel is prone to rusting. That limits its functionality in outdoor applications. To address that problem, steel can be galvanized by adding a solid zinc coating that effectively blocks corrosive elements such as moisture. In short, perforated galvanized steel sheet metal takes the strength of raw steel while increasing where and how you put it to use.

Perforated iron    

Almost no other metal is more time-tested than iron. Perforated iron, also known as carbon steel, couples the trusted strength of iron with modern applications. At our company, we work with the highest-quality metals to bring you panels perfect for any application.

Perforated Stainless Steel

Quality perforated stainless steel can be used in several applications, as it is strong, resistant to corrosion, and visually attractive. We make it our mission to adhere to the highest standards of perforated metal of all kinds. Below, read more about our services in perforated stainless steel and the wide range of applications ideal for stainless steel.

What Makes Perforated Stainless Steel Unique?

Perforated stainless steel sheet metal is a common material for functional and decorative structures. Its properties make it ideal for several reasons: notably, its resistance to corrosion and rust. It provides excellent corrosion resistance when left unfinished, or it can be finished with a variety of coatings to customize its appearance and further increase its longevity.

Perforated stainless sheet metal is also highly regarded as a sustainable, re-usable resource. This material can be produced from recycled material and lasts for generations. Perforated stainless steel can also be completely recycled when it is deemed no longer useful for its existing purpose.

Countless Applications

From outdoor decorations and sun shades to stairs and machinery, stainless steel perforated sheet metal can be used for endless purposes.

Perforated stainless steel is used in air diffusers for the HVAC market, acoustical panels for noise control, support for water filtration media, and architectural elements in building construction. These are just a few of the countless applications for perforated stainless steel.

The unique perforating tooling allows the material to retain a smooth edge after corrugating. The perforated stainless filter baskets utilize 316L grade stainless for petroleum and other harsh chemical processing to resist corrosion.

Perforated aluminum

Perforated metal can complement any structure and add a visually stunning element to interiors and exteriors alike. Perforated aluminum is an excellent option for designs of all types.

The Benefits of Quality Perforated Aluminum

Perforated aluminum sheet metal is a popular option, both for functional and aesthetic reasons. Aluminum is very versatile. Compared with many other metals, it is naturally lightweight and easy to work with. It is highly resistant to corrosion, making it ideal for indoor and outdoor applications. Most importantly, aluminum is a cost-efficient material that is well worth the investment.

Perforated Copper

Perforated Copper

Perforated copper sheet metal is visually stunning and has countless practical uses in structures, furnishings and more. At Dongjie Company, we are leaders in perfectly crafted perforated copper products.

A Quality Material

Copper is one of the oldest building materials, and it is among the most trusted. It is durable, malleable and has ideal properties for various types of structures. Perforated copper plates are well suited for both indoor and outdoor structures.

Perforated copper is often left unfinished, and when exposed to the weather it eventually forms a highly corrosion resistant outer surface of copper carbonate with a characteristic green color. It can also be coated with a wide variety of finishes to suit the application. Perforated copper can be created from recycled materials, and is itself 100 percent recyclable.

It is also considered to be an environmentally friendly option. With a virtually unlimited lifespan, perforated copper is a highly sustainable choice.

Endless Applications

From simple perforated sheets and plates to complex perforated copper corrugated or formed panels, the applications for this type of perforated metal go on and on. In many cases, perforated copper adds an aesthetic element to many structures.

Perforated Plastic

How Does Perforated Plastic Compare With Perforated Metal?

Perforated plastic can be used much like its metal counterpart. It is made via a pressing process that can create panels in varying thickness and perforation style. The end product is a perforated panel that, at a glance, is identical to a perforated metal panel.

Why would you opt for a plastic alternative? Generally speaking, plastic panels are better suited for applications that require lighter panels. For that same reason, plastic panels typically are less able to bear the same weight as metal.

Here are a few key benefits of perforated plastic panels that make it an excellent option for your design:

- Plastic is lighter. It can be easier to install and puts less strain on the rest of your design.
- Plastic is less expensive. Plastic panels can help you keep within a tighter budget.
- Plastic is chemical resistant. Some harsh environments, such as factories and storage, might expose your structure to corrosive chemicals. Perforated plastic holds up very well in these conditions.
- Plastic is corrosion resistant. Unlike many metals, such as aluminum and stainless steel, plastic will not rust or corrode.
Applications for Perforated Plastic

From traditional perforated panels to perforated plastic pipe, plastic has long been a staple in design. Here are a few common applications:

- Machinery. Perforated plastic and perforated plastic tubing with a high melting point are perfect for machinery and filtration.
- Ventilation. Like with perforated metal, perforated plastic is excellent for enhancing airflow and promoting better ventilation. Additionally, for cooling a building, plastic panels allow airflow while not getting hot themselves from natural sunlight.
- Lighting. Perforated plastic gives you more control over the use of natural light in your facility.
- Aesthetics. One of the key advantages of perforated plastic is that you can customize it. The right design can take full advantage of the functional benefits of perforated plastic while adding an impressive visual element to any design.

Finishings

 We supply a wide range of interior and exterior finishes, such as anodizing, plating, painting, powder coating and more.

Anodizing

Anodizing is an electrolytic process used to increase the thickness of the oxidation that naturally forms on the surface of many metals. Typically used with aluminum, anodizing takes advantage of the inherent properties of aluminum oxide to create a hard, corrosion-resistant surface. Anodized aluminum has an attractive metallic sheen, and can be either clear or dyed in various colors.

Clear Coat (Anodizing)

Clear Anodizing is a process that creates a thin layer of aluminum oxide coating on aluminum metal without the use of dyes or pigments.

E-coating

E-coating is an electropainting or electrophoretic lacquering process to deposit a paint or lacquer coating.

Electrogalvanized

The most common galvanizing method is electrochemical deposition of the zinc alloy. Because this process creates a relatively thin layer of galvanization, painting is generally recommended for outdoor applications to provide the best corrosion resistance.

Hot-dip galvanization

The part is passed through a molten zinc bath, providing a much thicker coating of zinc at a somewhat higher cost compared to electrogalv. Hot-dip galvanization produces a characteristic crystallization pattern or “spangle” on the surface.

Paint grip

Galvanized steel that is dipped in a phosphate bath for additional corrosion protection and to improve paint adhesion.

Plating

Plating refers to a number of processes for depositing a coat of one type of metal on the surface of another. Plating materials can be chosen for their beauty, corrosion resistance, hardness and a variety of other purposes. Examples include gold, silver, chrome, zinc, tin, cadmium and many others. Plating techniques also vary, and include both electroplating and electroless methods. Contact us to discuss the right plating material and method for your project.

Powder Coating

Powder Coating is an electrostatic process for applying a dry, powdered material such as polyester, polyurethane or epoxy. The piece is then heat-cured to flow the material together and create the final finish. Powder coating is generally thicker and more durable than paint, although the cost can be somewhat higher depending on the project. A broad selection of colors is available.

Large sheets and coils, corrugated pieces, finished components and even special designs – Accurate Perforating can apply virtually any finish to perforated part, as long as we determine that the finish is appropriate for the material. Contact us to discuss your finishing ideas and questions.
