What is 4.27# Expanded Metal

4.27# expanded metal is a standard-sized expanded metal product defined by its regular diamond opening pattern and fixed dimensional specifications, widely used in North American and international construction markets. The #4.27 designation represents a standard industrial size classification for expanded metal products.

This standard specification is widely adopted in flooring, fencing, industrial platforms, architectural decoration, and structural support applications due to its balanced open area, strength, and weight characteristics. It is one of the most popular medium-sized expanded metal products in the global market.

4.27# expanded metal maintains the inherent advantages of expanded metal: one-piece forming without welding, high structural strength, lightweight design, and excellent ventilation and light transmission properties. Its standardized dimensions make it easy to install and compatible with industry-standard frameworks.

At ANPING METAL MESH, we produce 4.27# expanded metal using premium raw materials and precision manufacturing equipment. As a professional China expanded metal mesh manufacturer, we ensure every sheet of 4.27# expanded metal meets strict dimensional tolerances and quality requirements for global customers.

Standard Specifications of 4.27# Expanded Metal

The standardized specifications of 4.27# expanded metal ensure consistency across production batches and compatibility with global engineering designs. The diamond opening of 40×20mm provides an optimal balance between open area and structural rigidity for general-purpose applications.

We offer three standard thickness options for 4.27# expanded metal to accommodate different load-bearing requirements: 1.5mm for lightweight applications, 2.0mm for general use, and 2.5mm for heavy-duty industrial scenarios. All thicknesses maintain the same opening pattern for design consistency.

Our 4.27# expanded metal is available in standard sheet sizes that fit common transportation and installation requirements. Custom cut-to-size services are also available for project-specific needs. Complete product parameters can be viewed on our products page.

Materials for 4.27# Expanded Metal

We produce 4.27# expanded metal using high-quality materials to meet different environmental, corrosion-resistance, and strength requirements. Material selection directly impacts the service life, performance, and application scope of the final product.

Cold-rolled carbon steel is the most common material for 4.27# expanded metal, offering excellent formability, high strength, and cost-effectiveness. It is ideal for indoor and protected outdoor applications where corrosion is not a primary concern.

Hot-dip galvanized carbon steel provides superior corrosion resistance for outdoor, industrial, and marine environments. The zinc coating protects the base metal from rust and extends service life significantly. Our hot-dip galvanized expanded metal sheet in 4.27# size is a top-selling option for outdoor projects.

304 and 316 stainless steel 4.27# expanded metal is used in corrosive environments, hygienic applications, and high-end architectural projects. It offers exceptional rust resistance, easy cleaning, and an attractive finish suitable for visible applications.

Aluminum 4.27# expanded metal provides lightweight, non-rusting performance for weight-sensitive applications like transportation, architectural facades, and decorative elements. For specialized needs, we also offer nickel, copper, and titanium alloy options from our alloy expanded metal mesh series.

Surface Treatments for 4.27# Expanded Metal

Surface treatments enhance the durability, appearance, and corrosion resistance of 4.27# expanded metal, extending its service life and adapting it to specific environmental conditions. We offer a full range of surface finishing options for our standard 4.27# expanded metal products.

Hot-dip galvanizing is the most popular surface treatment for 4.27# expanded metal, providing a thick, durable zinc coating that withstands harsh outdoor conditions, moisture, and chemical exposure. It is the preferred choice for industrial platforms, fencing, and structural applications.

Electro-galvanizing offers a thinner, more uniform zinc coating for indoor or light-duty outdoor applications, providing basic corrosion protection at a cost-effective price point. It is suitable for interior industrial applications and temporary structures.

Powder coating provides unlimited color options and a smooth, durable finish for architectural and decorative applications. Our powder-coated expanded metal facade mesh in 4.27# size delivers exceptional aesthetic performance for building exteriors.

Anodizing is exclusively used for aluminum 4.27# expanded metal, creating a hard oxide layer that enhances corrosion resistance and provides metallic color finishes. Passivation is standard for stainless steel versions to maximize their natural corrosion-resistant properties.

Manufacturing Process of 4.27# Expanded Metal

Our 4.27# expanded metal is manufactured using advanced CNC-controlled expanding machines to ensure precise dimensions, consistent patterns, and high product quality throughout the production process.

The process begins with precision leveling of raw metal coils to eliminate imperfections and ensure uniform thickness, a critical step for maintaining accurate opening dimensions in the final 4.27# expanded metal product.

The automated expanding machine simultaneously slits and stretches the metal sheet to form the uniform diamond pattern characteristic of 4.27# expanded metal. The CNC system ensures consistent opening size and strand width across the entire sheet surface.

After expanding, the sheets undergo flattening (if required), cutting to standard dimensions, deburring, and surface treatment. Every sheet is inspected for dimensional accuracy, pattern consistency, and surface quality before packaging.

Our Anping expanded metal mesh factory operates strict quality control protocols for 4.27# expanded metal production, ensuring compliance with international standards and customer requirements for every batch.

Key Applications of 4.27# Expanded Metal

4.27# expanded metal is a versatile product widely used across construction, industrial, architectural, and engineering fields due to its balanced specifications and reliable performance. Its standardized size makes it a preferred choice for engineers and contractors worldwide.

In the construction industry, 4.27# expanded metal is used for industrial flooring, walkways, stair treads, and safety fencing. The diamond pattern provides anti-slip performance and structural strength while allowing debris and liquid to pass through, making it ideal for industrial platforms.

Architectural applications use 4.27# expanded metal for facade cladding, sunscreens, interior partitions, and decorative elements. Our expanded metal mesh for facade decoration in 4.27# size combines aesthetic appeal with structural integrity for modern buildings.

Industrial applications include machinery guards, filtration screens, ventilation grilles, and equipment enclosures. Our expanded metal mesh for filtration in 4.27# specification provides reliable particle separation and airflow for industrial systems.

Additional applications include security screens, automotive components, agricultural equipment, drainage covers, and protective fencing. The versatility of 4.27# expanded metal makes it suitable for nearly all medium-duty expanded metal applications.
