The term “expanded metal screen” refers to a type of security metal screen panels made from thin sheet metal that is slit and stretched in a pattern that results in uniformly-sized holes. Also known as micro-mesh, expanded metal screens are commonly used in industrial environments. They range in size from a fine filter to an industrial-strength screen. They provide an effective barrier against intrusion while providing ventilation.

        This material is highly versatile and is an economical choice compared to perforated options. The expanded metal sheets are stretched rather than punched, and the strands can be almost completely transparent depending on the thickness. Despite its strength, expanded metal has many advantages over perforated screens, including the fact that it is less likely to ravel, unlike woven-wire products. Besides its cost-effectiveness, expanded metal is also versatile and comes in a variety of sizes and weights.

          Color Options Of Expanded Metal Screen Panels

          These products are designed to prevent unwanted entry and allow natural light into the space, all while offering some degree of privacy. Metal screens can even reduce solar heat by 50%. Security screens can be made to fit any opening size and type of application. In addition, many security screens are available with a powder coating for aesthetic appeal and weather resistance. They are available in various color choices to suit any business environment. You can also choose to install it as a stand-alone door for convenience.

          Expanded metal screen made from aluminium can be flexibly processed with surface finishes, there are generally two common process methods that are excellent for aluminum, including powder coating and anodizing. Each of them has its own benefits to achieve different effects. Below is some brief information about these finishing methods for consumers to choose to meet their desired styles.

          Anodized finish is a processing combination of electrolytic & chemical, it can help process the metal surface with a layer of natural oxide layer, which can make the appearance with decorative effect, and improve its resistance to corrosion and oxidation. Aluminium is the most proper substrate for anodizing, anodizing process can perfectly generate a tough protective layer of aluminium oxide on the surface, unlike other finishing types such as plating or painting, it’s not easy to peel and chip.


          • The anodizing layer on the surface is resistant to severe weather.
          • The anodizing material is durable and tough, and not easy to wear and peal off.
          • When the anodizing is being processed, some elements can be added in to give it more colors available.
          • The anodizing layer can be the under layer for the surface enhancement.

          Powder coated finish is processed with a dry finishing process that are commonly used for metal surface treatment. When a low electric current is running through the sheet metal, the powdered polymer coating is sprayed on the metal surface, the coating material forms a bond when it come through an electrostatic process, then quickly cured with heat to be a hard and colored layer. Powder coating provides many functional properties and rich color options for aesthetic effects.


          • The color and appearance of powder coating can be retained originally for long time.
          • The layer of powder coating is much thicker than other traditional paintings, and it’s more tough and evenly distributed.
          • Materials for powder coating are environmentally-friendly as it releases nearly no volatile organic compounds into the air.
          • A wide variety of color options are available to help metal achieve stunning and eye-catching appearance.

          Notes: powder coated finish doesn’t suit all types of metals.

            Applications For Expanded Metal Screen

            For security purposes, expanded metal is commonly used in buildings. The expanded metal mesh provides a high level of strength and load bearing capacity. It is also anti-slip due to its large area of openings. Expanded metal screens can be used to prevent slipping on stair treads or as a security grille on doors and windows. These screens can be fabricated into attractive designs and can be painted to improve their lifespan.

            The advantages of expanded metal over other wire mesh materials include its relatively low weight and high strength. When flattened, it is more durable than other types of wire mesh and can be produced at a lower cost. The main features of this material are its light weight, low production costs, and ease of installation. There are five major categories of expanded metal screens: protection, enclosure, support, filtration, and decoration.

              Processes Of Making Expanded Metal Screen

              There are several different processes for making an expanded metal screen. The first step is to cut the sheet metal to the exact size needed. The metal is then stretched and slit by the use of dies. The resulting structural network is a dense and durable screen with a high strength-to-weight ratio. The expanded metal sheet may be manufactured from steel or aluminum, and the material can also be coated with a powder coating or paint.

              Another important factor in the process of making a commercial security expanded metal screen is the density of the openings. This determines how easy the screen will be penetrated. The micro-mesh openings can be as small as 0.6 mm in size. Another factor to consider is the density of openings. An expanded metal screen can contain thousands of tiny openings, but a single screen with a hundred larger openings will allow the same amount of air to pass.

              The Benefits Of Expanded Metal Screen Panels

              When installed properly, expanded metal screen panels are a smart choice for your home or business. Not only do they protect your investment, but they are easy to clean, too. If you’re wondering if expanded metal is worth the investment, read on for some reasons why. The benefits of expanded metal screening are obvious. Compared to traditional woven or welded wire mesh, expanded metal has fewer joints, making it a more cost-efficient and environmentally friendly option for screens.

              What To Consider When Buying Bead Blast Finish Stainless Steel?

              If you’re looking for a bead blast finish for your stainless steel fabrications, there are a few things to keep in mind. This charter will discuss the factors to consider when choosing this finish and what to look for in a bead blasting cabinet. This durable finish is ideal for stainless steel projects, as it will prevent corrosion and create an attractive look for your products.

              Bead blast finish is a finish that is suitable for a variety of materials, including aluminum oxide, glass, and shredded nutshells. This finish is typically non-directional and has a smooth, uniform appearance. Although this finish is often used in the food and pharmaceutical industries, it can also be used for street furniture and sculptures. The benefits of bead blast finish stainless steel are numerous.

              One of the most important factors when choosing a bead blast finish stainless steel is its ability to achieve a satin finish. A glass bead will produce a satin-like finish without profiling the surface. The other common material used for this finish is aluminum oxide, which is harder than glass beads. Plastic is softer and is best suited for removing paint from fiberglass parts.

              The process of bead blasting uses high air pressure to spray tiny glass beads onto the surface of a component to create a matte finish. The beads will not leave a profile for paint to adhere to and will result in an even, uniform surface finish. The process does not affect the size of the component and is very suitable for restoring classic cars. When choosing a bead blast finish, consider your budget when purchasing one.

              Bead blasting is a very expensive process. Despite its advantages, it can also cause problems for your project. Almost 90 percent of all bead blasting projects end up with an ugly, dull finish. Glass bead blasting has become popular among restoration professionals for years, but it is no silver bullet. The glass beads can only remove a small percentage of contaminants, and you’re unlikely to get a high-end finish with this method.

              The most important factor to consider when buying bead blast finish stainless steel is the quality of the machine. A good bead blasting cabinet is equipped with the highest-quality bead blasting tooling. It also has a cabinet with essential features. If the product is too expensive, consider the benefits of bead blasting. You may save money and be able to buy a better product in the future.
