Different Types of Steel Grilles and Which To Choose?

In this blog, different types of steel grilles will be introduced as there are several types of steel grilles, each with its unique characteristics and applications. Some of the most common types of steel grilles, including woven wire mesh grilles, perforated metal grilles, expanded metal grilles, bar grilles, welded steel grilles, aluminum steel grilles and steel safety grilles will be discussed to help you choose the right one for your specific application.


What is Steel Grille?

Steel grilles are rigid, mesh-like structures made from steel bars or steel wires that are welded or woven together to form a durable and strong mesh pattern. They are applied in a variety of applications, such as security barriers, ventilation covers, and architectural ornamentation.


Depending on their intended application, they are available in a variety of sizes, forms, and designs that are produced from various grades of steel. In addition, they can also be coated with various finishes to enhance their durability, resistance to corrosion, and aesthetic appeal.


Overall, steel grilles are a versatile and reliable solution for a wide range of applications, providing both security and decorative benefits. Let’s explore the different types of steel grilles to help you determine which suits your needs!


The Different Types of Steel Grilles​

Woven Wire Mesh Grilles

Steel wires are intertwined at right angles to create stiff mesh patterns for woven wire mesh grilles. They are frequently utilised as decorative elements in furniture design, on speaker grilles, and on radiator covers.



Woven wire mesh grilles are highly customizable, with a wide range of wire gauges, patterns, and finishes available to match the specific design needs of a project. They can be made from different grades of steel, including stainless steel, which provides added corrosion resistance and durability.

Perforated Metal Grilles

Perforated metal grilles are steel grilles that have a pattern of holes punched through them. The holes can be of different shapes, sizes, and spacing, and can be arranged in various patterns to create a unique design. The resulting pattern of holes creates an open area, which allows for airflow and ventilation, while still providing a level of security.


Then, perforated metal grilles are also durable and long-lasting, making them a reliable solution for a wide range of applications. They are resistant to wear and tear, and can withstand exposure to the elements without rusting or corroding.

Expanded Metal Grilles

Expanded metal grilles are steel grilles made by stretching and flattening a piece of metal sheet into a diamond-shaped pattern. This process creates a durable, strong, and lightweight product that can be used in a variety of applications.


The expanded metal pattern allows for good airflow and visibility, making it suitable for ventilation, screening, and security applications. The size and shape of the diamond-shaped openings can be customized to meet the specific needs of a project, and the metal sheet can be cut to the desired size and shape for easy installation.

Bar Grilles

Bar grilles are steel grilles that consist of horizontal and/or vertical bars arranged in a pattern to create an open area. The bars can be made of various materials, such as steel, aluminum, or brass, and can be finished in a range of colours and textures to match the aesthetic requirements of a project.


Besides being used as decorative features in architectural and interior design applications, bar grilles are also commonly used for air ventilation and filtration, as well as for security purposes in areas such as doors and windows. 

welded steel grille

Welded Steel Grilles

Next, welded steel grilles are a type of steel grille made by welding individual steel bars or rods together to form a rigid, durable and robust structure. The steel bars can be arranged horizontally or vertically, or both, and welded at the intersections to form a strong, flat surface.



Welded steel grilles can be made from different types of steel, such as carbon steel, stainless steel, and aluminum. Other than that, they can be finished in a range of colours and textures to match the aesthetic requirements of a project.

Aluminum Steel Grilles

Aluminum steel grilles are a type of metal grille made from a combination of aluminum and steel. The grilles are created by bonding aluminum sheets to steel frames, resulting in a lightweight, strong and corrosion-resistant structure.


The aluminum sheets provide a lightweight and corrosion-resistant surface, while the steel frames provide strength and rigidity. The combination of aluminum and steel allows for a strong, durable and long-lasting grille that is resistant to rust and corrosion, making it ideal for outdoor applications. Aluminum steel grilles can be customized and finished in a range of colours, textures, and patterns to match the design and style of the building or application.

Steel Safety Grilles

Lastly, steel safety grilles are a type of metal grille used for safety and security purposes. They are designed to provide protection against intruders, while still allowing for ventilation and natural light. These grilles are commonly used in commercial and industrial settings, such as warehouses, factories, and retail stores.


They are made from high-strength steel bars, welded together to form a rigid structure. The bars are spaced apart to allow for ventilation and visibility, while still providing a strong barrier against intruders. The grilles are typically powder-coated or painted to provide additional protection against rust and corrosion.

Why Steel Grilles?

Based on the brief description of different steel grilles above, we can assure that there are several benefits to using steel grilles compared to other materials, including:


Steel grilles are strong and can withstand significant force and impact, making them an ideal choice for security applications such as doors, windows, and fences. In addition, they provide a physical barrier against intruders while allowing for natural light and ventilation.


Steel is a very durable material that can withstand harsh weather conditions and heavy use. They are a long-lasting option for many applications due to their resistance to corrosion, rust, and wear and tear.


Steel grilles can be easily customized to meet the specific requirements of a project. They can be made in a wide range of sizes, shapes, and configurations to fit any application. Additionally, they can be painted or powder-coated to match the surrounding décor. For instance, we customized end products based on clients’ requirements such as drum stands, and some motorcycle parts.


Steel grilles allow for natural ventilation, making them an excellent choice for applications such as HVAC systems and building facades. They can be designed with varying degrees of open space to allow for optimal airflow.


Steel grilles are a cost-effective option compared to other materials, such as aluminum or titanium. While other materials such as aluminum or plastic may also have their own advantages, steel grilles offer a combination of security, durability, customizability, ventilation, and cost-effectiveness that make them a popular choice in many applications.

In conclusion, steel grilles are an essential component in many industries and applications. Choosing the right type of metal grille for your project depends on several factors, including the desired level of ventilation, security, and aesthetics.


If you are looking for a metal grille for your project, it is recommended that you carefully consider your requirements and consult with an expert in the field. Consider factors such as the application, required level of ventilation, desired level of security, durability, or aesthetic preferences. You should also consider the material and finish of the grille, as well as the size and spacing of the openings. With the right information and guidance, you can choose the best steel grille for your project that will provide the necessary functionality and meet your aesthetic requirements.
