Expanded Metal

All-Specification Expanded Metal

What is expanded metal?
1.Raw materials of expanded metal: Expanded metal is made from various metal material such as steel, aluminum, stainless steel, copper, and brass.
2.Manufacturing process of expanded metal: The metal sheet is slit and stretched by machines to form a uniform expanded metal mesh with a three-dimensional diamond-shaped pattern.
3.Advantages of expanded metal: It is formed as a single piece without welding, with a flat surface, uniform openings, high tensile strength, and excellent durability and safety.

The high quality of expanded metal from Shang Kai Steel comes from:
1.Expanded metal is entirely made using metal materials from CSC (China Steel Corporation), with proof of material batches and sourcing available.
2.With a highly precise and standardized manufacturing process, each piece of expanded metal maintains a dimensional tolerance within ±3mm. This ensures easier and faster installation, significantly reducing labor time and cost. The expanded metal made by Shang Kai Steel can be used approximately 60 years.

  • Expanded metal can be applied across various industries such as building construction, architectural facades, interior decoration, and specific industrial materials.
  • The raw materials of expanded metal are selected based on the specific application needs and performance requirements.
  • The specifications and design of expanded metal—including mesh size, shape, and pattern—are chosen according to the industry requirements.

Filtering Transparency

The diamond pattern of expanded metal delivers precise airflow control. Fine metal mesh is widely built into automotive air-conditioning and cooling systems to filter impurities while letting a calibrated volume of air pass through.

Stability & Safety

The slip-resistant surface of expanded metal mesh can be laminated to glass, concrete or plastic, forming robust metal mesh panels that boost structural durability and safety.

Greening & Energy Saving

Expanded metal has already had two green-building material certifications and a full life-cycle carbon audit. As an architectural facade, it helps projects earn green-building labels, win ESG tenders or obtain government subsidies.

Design Flexibility

Because the diamond patterns of expanded metal are continuous, the expanded metal can be cut, spliced or framed to make creative designs.

Surface Treatment

An expanded metal sheet can receive hot-dip galvanizing, metal plating, powder coating or plastic over-molding, allowing engineers to match any aesthetic or environmental requirement.

Standard Expanded Metal Mesh

Standard Expanded Metal Mesh

General Model, Standard SpecificationExpanded metal mesh for public walkways, elevated platforms, stairs, railings, and partitionsShang Kai Steel’s standard expanded metal mesh, a versatile and widely used building material, is designed to meet the functional and structural needs of the Taiwan market. This form of metal mesh integrates durability, sustainability, and architectural flexibility across infrastructure and public works. Lightweight yet strong and safeCompared with other metal mesh types, standard expanded metal mesh maintains structural integrity while being significantly lighter in weight. It is manufactured using first-grade steel from China Steel Corporation (CSC), with batch certification available. The expanded metal mesh is produced through a standardized, high-precision process—its surface is flat, apertures are uniform, edges are burr-free, and dimensional tolerances are controlled within ±3 mm. This makes it ideal for public walkways, platform mesh, and large-scale infrastructure projects.2. Customizable apertures for privacy and ventilationThe mesh can be tailored in terms of aperture size, angle, and arrangement. Thanks to the three-dimensional structure of architectural metal mesh, it can obscure direct lines of sight from multiple angles while allowing natural airflow. This dual function makes it an excellent solution for fences, partitions, and privacy screens in both residential and commercial outdoor spaces.3. Corrosion-resistant surface treatmentsSurface finishes on expanded metal mesh not only enhance appearance but also add a protective layer to resist oxidation and corrosion. Shang Kai Steel offers various surface treatments based on material type: Steel mesh: hot-dip galvanized for superior durability Aluminum mesh: anodizing, powder coating, or fluorocarbon coating Stainless steel mesh: electroplating for long-term protectionThese options ensure long-lasting performance in various environmental conditions.4. Flexible processing and edge protectionIn addition to surface treatment, Shang Kai Steel provides custom services such as cutting expanded metal mesh to specific dimensions or enclosing the edges for added safety. These processing options support faster, safer, and more efficient construction and installation.5. Sustainable material aligned with 3R principlesThe production of expanded metal mesh involves slitting and stretching without material waste, in line with the 3R principles: Reduce: Mesh has a service life of up to 60 years, minimizing maintenance and replacement. Recycle: At the end of its use, the mesh can be collected and processed. Reuse: Recycled metal can be remanufactured into new mesh products.As a result, expanded metal mesh stands out as an eco-friendly green building material choice for modern architecture.Expanded Metal Is Available In The Following Metal TypesCarbon SteelPre-Galvanized SteelHot Dip Galvanized SteelStainless SteelAluminum Inquire about the available materials, hole sizes, shapes, patterns, thicknesses, and finishes.ApplicationsExpanded mesh can be used in various applications, including maintenance walkways, building stairs, platforms, balcony railings, partitions, fences, and screens.
