FAQs

Expanded metal mesh is produced by a special processing method in which metal sheets or coils are cut and stretched. This type of metal mesh has a distinctive mesh-like structure, resembling a grid or lattice, where the original openings in the metal material are stretched and expanded, creating 3D diamond-shaped mesh strips and openings.

First, it's important to select a ductile metal, typically stainless steel, aluminum, copper, galvanized steel or other metals like sliver, gold.. ect. Each material has different characteristics and suitability, and the choice of material should consider factors such as intended use, strength, and appearance.

• Thickness：The thickness of expanded metal can range from very thin to relatively thick. We at Shang Kai Steel can produce a range from 0.05mm to 8.0mm.
• Width：The width of the sheets can usually be customized based on specific requirements. Common market sizes range from 305mm to 3050mm.
• Length：Expanded metal sheets can be manufactured in rolls with lengths that can reach several feet, or they can be cut into desired pieces with lengths adjusted according to specific application needs. Common market sizes range from 1830mm to 3050mm.

Mesh Size： 

Thickness Measurement

Raw material thickness: Refers to the thickness of the sheet metal used to make the expanded metal mesh.

SW Measurement

SW (Short way)：SW represents the short (horizontal) side of the diamond-shaped openings.

LW Measurement

LW (Long way)：LW represents the long side (vertical) width of the diamond-shaped openings.

Strand Measurement

String：Refers to the lines or bars within the expanded metal mesh.

Shang Kai Steel can customize the design of Expanded metal mesh to meet specific application requirements and design needs.

Filtration Function

Metal mesh can be used as a filter to separate solid particles, liquids, or gases from contaminants. This is common in industries such as water treatment, air filtration, food processing, and the chemical industry.

Ventilation Function

Expanded metal mesh provides ventilation by allowing air or gases to pass through while preventing solids from entering. This is particularly useful in applications such as construction, machinery, and vehicle engine cooling systems.

Safety And Decorative Design:

Expanded metal mesh can be used as guardrails, handrails, protective covers and more to ensure the safety of personnel or equipment. It prevents accidental contact with hazardous areas, such as moving mechanical components. In addition, the unique appearance and texture of expanded metal mesh makes it a decorative element in architecture and interior design. It can be used for railings, partitions, ceilings, wall decorations and other applications to enhance visual appeal.

Insulation And Screening

Woven metal mesh is an effective means of isolating specific areas and preventing unauthorized access. Its dual benefit of maintaining visibility and proper ventilation makes it an ideal choice for security applications.

Safe Walkways And More

Expanded metal mesh is widely used in the construction of walkways, stairs and bridges. These panels provide a safe walking surface while promoting ventilation and drainage. Their rugged design ensures durability in harsh environments. In addition, in some cases, the surface texture of expanded metal can provide valuable anti-slip properties, making it a suitable choice for a variety of environments, especially in wet or slippery conditions.

Metal expanded mesh made of steel can be improved in performance, appearance, and durability through various surface treatment method.

Here are some common surface treatment methods for steel mesh:
Hot-dip Galvanizing: Hot-dip galvanizing is a common method of surface treatment in which the metal mesh is immersed in a solution of zinc to create a protective coating of zinc. This coating helps prevent the expanded metal from corroding and oxidizing, thereby extending its life.

Anodizing: Anodizing is commonly used for aluminum metal mesh. This process involves the formation of an oxide layer on the metal surface. Anodizing takes advantage of aluminum's tendency to oxidize by controlling the formation of the oxide layer through electrochemical methods. This prevents further oxidation of the aluminum and improves its surface mechanical properties. In addition, anodizing can produce different colors through various chemical reactions, which enhances aesthetics. The oxide layer typically has a thickness of 6μ to 15μ.

Powder Coating: Powder coating is a very popular surface treatment method known for forming a durable, wear-resistant coating on various material surfaces. It provides excellent corrosion resistance, scratch resistance and durability. Industries such as construction, automotive, machinery, furniture, and more use powder coating extensively. Coating thickness typically ranges from 40μ to 150μ.

Fluorocarbon Coating: Fluorocarbon Coating can withstand sunlight, UV rays, rain, and extreme temperature changes, providing exceptional weather resistance. It is a high-performance coating. It is commonly used for both protection and decoration of metal surfaces. This type of coating is suitable for exterior applications including building exteriors, roofs, bridges and more. Coating thickness typically ranges from 40μ to 50μ. The finish can meet the 10-year AAMA 2605-05 specification.

Electroplating: Electroplating is a process used on stainless steel metal mesh to create a metal coating on the surface through the application of electric current and chemical processes. Stainless steel is naturally gray-silver in color, but after chromium electroplating, it becomes bright silver-white. This process enhances corrosion resistance and improves appearance. It also maintains the electrical conductivity of stainless steel.
