Metal decorative mesh is a new type of building decoration material, which is widely used in building facades, partitions, ceilings, sunshades, balconies and corridors, roller blinds, stairs, etc., as well as high-end interior and exterior decoration of airport stations, hotels, museums, opera houses, concert halls, office buildings, exhibition halls, shopping malls and other places.

The metal decorative mesh of the building has the characteristics of non-combustibility, high strength, firmness, and easy maintenance. It has the advantages of strong protection and strong functions, and the decorative effect is vivid and firm, which can well protect the building structure. Its installation is simple and quick, and the appearance is unique and elegant. Different light, different environment, different time, and different viewing angles will show different viewing effects.

What Are The Metal Mesh?

Classification by processing：

1.Woven wire mesh - metal mesh and metal mesh curtain woven by machine with metal wires, cables and twisted wires.

2.Welded wire mesh - made of metal wires welded by special methods.

3.Expanding mesh-workStretched plate mesh is made of metal thin plates through mechanical cutting, stretching, pressing and other processes.

In this article, we mainly focus on Metal Expanded Mesh.

As a building material, metal expanded mesh (also known as stretched mesh) has the characteristics of light transmission, economy, strength, easy manufacturing and beauty. It has a wide range of applications, such as decorative curtain walls, steel structure platforms, hanging mesh in plastering layers, railings, ceilings, indoor partitions, furniture, vents, etc..

• Manufacturing process

The manufacturing process of the expanded mesh is relatively mature, mainly using the punching and shearing process. The punching and shearing machine punches and shears downward from the edge of the metal plate. The metal plate placed on the platform is stretched while being cut, and the punching and shearing machine is lifted up to process a whole row of mesh holes.

• Material and surface treatment

Metal expanded mesh is a cold-processed metal plate. Due to corrosion and rust prevention issues, metal needs to be surface treated. Different surface treatments directly affect the surface texture and physical and chemical properties, and the cost also varies greatly. Common treatment methods such as galvanizing, fluorocarbon spraying, powder spraying, anodizing, etc. are suitable for the surface treatment of metal materials, and are basically also suitable for metal expanded mesh.

• Shape

The appearance of the expansion net is mainly divided into vertical expansion net and horizontal expansion net.

The function of The Expanded Metal Mesh

1. Compared with other translucent metal materials (such as perforated metal sheets and metal woven mesh), expanded mesh has better out-of-plane strength, its total thickness is greater than that of original metal sheets, and it has a better moment of inertia, which makes it more suitable for installation on facades subject to wind loads.

2. Expanded mesh has been used as a sound-absorbing material in areas other than architecture. For example, the sound absorption mechanism of mechanical equipment exhaust vents and the surface of audio equipment is the same as that of perforated metal plates, both of which belong to resonant sound-absorbing structures.

3. Sunshade, heat insulation, ventilation: When the expanded mesh is used as a protective structure, it forms the first protective barrier between the building and its surrounding environment, providing sunshade, heat insulation, and ventilation, which can effectively improve the energy saving level of the building in a humid/hot environment. As a passive energy-saving method, the expanded mesh decorative layer takes into account the overall thermal performance and visual comfort of the building. Compared with complex mechanized shading systems, the expanded mesh skin can define the appearance of the entire building and reduce building energy consumption.

Why is aluminum an ideal metal?

Aluminum, a metal that is ubiquitous in modern society, has established its position as a key basic material due to its excellent comprehensive performance. The core advantage is that it achieves the perfect combination of "lightness" and "strength". The density of aluminum is only about one-third of that of steel, and it is light in texture, but don't underestimate its strength. By adding other elements to form an alloy and after proper treatment, the strength of aluminum alloy can be comparable to or even exceed that of ordinary steel, thus obtaining extremely high "specific strength" (strength per unit weight). This makes aluminum revolutionary in the fields of pursuing weight reduction such as aerospace, automobile manufacturing and rail transportation, which can significantly improve transportation efficiency and reduce energy consumption.

Aluminum's corrosion resistance is also commendable. When exposed to air, a dense, strong and self-healing aluminum oxide protective film will quickly form on the surface of aluminum, effectively isolating it from the invasion of external corrosion factors. This natural protective ability can also be further enhanced by anodizing to form a thicker, more wear-resistant and colorful surface layer, making it both beautiful and durable in applications such as building doors, windows, curtain walls, and electronic equipment housings. Its good resistance to the atmosphere, water, a variety of chemicals and food also makes it an ideal choice for chemical containers, ship parts, kitchenware, and food packaging such as cans and aluminum foil.

Another highlight of aluminum is its excellent electrical and thermal conductivity. Although its conductivity is about 60% of copper, its lightness actually makes it twice as capable of transmitting current as copper by weight, making it the material of choice for high-voltage transmission lines and large cable conductors. Its good thermal conductivity, combined with its light weight, easy processing and cost-effectiveness, makes aluminum an indispensable material in radiators, heat exchangers and everyday cooking utensils (such as woks and steamers).

Aluminum is extremely process-friendly. It has good ductility and plasticity, and can be easily formed by a variety of processes such as extrusion (easily making profiles with complex cross-sections), rolling (producing thin plates and ultra-thin aluminum foil), forging, and stamping. Many aluminum alloys are also easy to cut. In terms of connection, welding (such as MIG/TIG welding, advanced friction stir welding), riveting, bolting or bonding can be reliably applied. This easy shaping and combination property greatly broadens its application range.

Aluminum also has excellent light and heat reflectivity and is non-magnetic. It can efficiently reflect visible light, infrared heat radiation and radio waves, which makes it a key material for lamp reflectors (improving lighting efficiency), building insulation materials (such as roof reflective foil), insulation life blankets and satellite antenna reflective surfaces. At the same time, its non-magnetic characteristics make it uniquely valuable in electronic and electrical equipment housings that need to avoid magnetic field interference, peripheral components of precision instruments (such as MRI equipment), and components near ship navigation equipment.

Safety and environmental protection are also important advantages of aluminum. Aluminum itself is odorless and non-toxic, and the stable oxide film on the surface ensures that it will not release harmful substances to the contact objects (especially food and medicine), so it is widely used in food and beverage packaging (cans, aluminum foil bags), cookware and pharmaceutical packaging. Even more prominent is its unparalleled recyclability. Aluminum is a model of circular economy. The energy consumption of recycling and remelting is only about 5% of that of primary aluminum production. Recycled aluminum can almost completely retain its original quality and can be recycled indefinitely without degradation. This powerful recycling capacity greatly reduces the overall energy consumption and environmental footprint of the aluminum industry, giving aluminum significant sustainability and the reputation of "green metal".

Finally, the beautiful and modern appearance of aluminum cannot be ignored. The natural silver-white luster gives it a modern feel, and through surface treatment technologies such as anodizing and spraying, extremely rich and diverse colors, textures and super surface durability (weather resistance, UV resistance, scratch resistance) can be obtained, which perfectly meets the dual needs of aesthetics and durability for building facades, interior decoration and consumer electronics.

Why we choose aluminum expanded fence

The aluminum expanded fence successfully combines the core advantages of aluminum, such as light weight, high strength, corrosion resistance, durability, easy processing, and recyclability, with the convenience and flexibility of telescopic fences. While providing reliable and safe protection, it solves the problems of traditional fences, such as being heavy, easy to rust, frequent maintenance, limited life, and environmentally unfriendly. Whether it is in construction sites, municipal projects, residential areas, industrial parks, event venues, or areas that require temporary or long-term isolation, aluminum expanded fences have become a modern enclosure solution worthy of priority and widespread use due to their comprehensive value of high efficiency, durability, environmental protection, and economy. Especially in highly corrosive environments or projects that focus on full life cycle costs and sustainability, its advantages are more prominent.
