Stamped Expanded Metal

MORE DETAILS

Stamped expanded metal is a type of metal sheet that has been processed through a stamping and stretching technique to create a mesh-like structure. Unlike perforated metal (which has holes punched out), expanded metal is formed by cutting and expanding the material, creating a pattern of interconnected openings without waste material.

Stamped Expanded Metal

Key Features & Advantages

Strength & Rigidity – The stamped expansion process increases the sheet’s structural integrity.

Lightweight & Cost-Effective – Less material is removed compared to perforated metal, reducing waste.

Good Ventilation & Drainage – Openings allow air, light, and liquids to pass through efficiently.

Slip Resistance – The textured surface provides traction, making it ideal for walkways and stairs.

Customizable Openings – Available in standard, flattened, or decorative patterns.

Common Applications

Industrial & Construction – Flooring, catwalks, and safety grilles.

Fencing & Security – Protective enclosures, gates, and partitions.

Filtration & Screening – Used in HVAC systems, sieves, and enclosures.

Automotive & Aerospace – Grilles, engine covers, and reinforcement panels.

Architectural & Decorative Uses – Facades, room dividers, and furniture accents.

RELATED FAQ

What is Wedge Wire Screen Tube?

The wedge wire filter element is a filter element composed of a "V" shaped stainless steel wire and a stainless steel support strip. Its smooth surface is the filter surface, and the gap is a strip, which belongs to the surface filtration form.

What are the primary applications of wedge wire Screen Tube?

Wedge wire filter elements are widely used in many fields, mainly including petrochemical, food and beverage, pharmaceutical, water treatment.

What is the difference between wedge wire filter elements and other wire mesh filter elements?

The wedge-shaped wire filter element has a higher filtration efficiency and can achieve extremely high filtration effects by controlling the particle gaps of the wedge-shaped mesh.

The wedge-shaped wire filter element is suitable for high-flow and high-pressure industrial filtration occasions, especially for industrial water, drinking water purification, sand separation and treatment, sewage treatment and other fields.

What is the material of wedge wire?

The main material of wedge wire is stainless steel. Specifically, wedge wire is usually made of high-quality stainless steel materials, such as 302, 304, 304L, 316L, etc.

Where are wedge wire screen tube used?

Industries include water treatment, oil and gas, pulp and paper, mining, and food and beverage.

What is the expected lifespan of wedge wire screen tube?

With proper maintenance, wedge wire screens can have a long lifespan, often exceeding 10 years.

What is a perforated metal anti-skid plate?

A perforated metal anti-skid plate is a type of metal plate that combines a perforated design with anti-slip or anti-skid features.

Where are perforated metal anti-skid plates used?

Industrial Flooring:

Used in factories, warehouses, and production lines as flooring or walkways to provide a non-slip surface for workers.

Staircases and Platforms:

Used for stairs, ladders, and elevated platforms to provide safe access and reduce the risk of slips and falls.

Vehicle and Transport Decks:

Commonly used in trucks, trailers, or shipping containers to create a stable, non-slip surface for cargo handling.

Outdoor and Marine Applications:

Used in outdoor environments such as docks, walkways, and industrial outdoor installations where water or mud can create slippery conditions.

What are the common types of perforated metal sheets?

Perforated Sheet with Raised Patterns: Features raised sections in the perforated pattern for enhanced anti-slip properties.

Serrated Metal Plate: Uses serrated edges or a textured surface in combination with perforations to improve skid resistance.

What is the material of perforated metal sheet?

▪Stainless Steel: Resistant to corrosion and durable, ideal for harsh environments like marine, chemical, or food processing industries.

▪Aluminum: Lightweight and corrosion-resistant, commonly used in transportation, aerospace, and exterior architectural applications.

▪Carbon Steel: Strong and cost-effective, often used in industrial and construction settings.
