Lightweight Expanded Metal Sheet Designed for Easy Cutting Splicing and Installation in Construction and Industrial Settings
I. Perforated Metal Plate
Perforated Metal Mesh (Perforated Sheet) is a metal product made by punching regular or irregular holes on metal sheets via precision stamping. Integrating structural strength and versatility, it is widely used in various industrial scenarios and can be customized in specifications, materials, colors and surface treatments to meet diverse application needs.
1.1 Core Product Features
Structural Stability: Adopting one-piece stamping, evenly distributed holes preserve the sheet’s original structural integrity. It has excellent compression and tensile performance, resists deformation and breakage, and has a long service life.
Multifunctional Adaptability: It has ventilation, light transmission, filtration, sound insulation, anti-slip and decorative properties. Functional focus can be adjusted by hole specifications to fit different scenarios.
High Customization Flexibility: Materials, hole diameter, shape, sheet specifications and colors can be customized to adapt to the personalized needs of industry, construction and decoration.
Facilitated Installation and Maintenance: Lightweight and simple in structure, it can be directly cut, spliced and installed. No complex later maintenance is needed, and it is easy to clean, reducing use costs.
1.2 Key Parameters (Core Specifications)
Sheet Specifications: Thickness 0.3mm–12mm (conventional 0.5mm–5mm); width 300mm–1500mm; length 1000mm–6000mm (cuttable and customizable).
Hole Diameter Specifications: Hole diameter 0.5mm–100mm (conventional 1mm–20mm); hole pitch 1mm–150mm. Hole density is customizable, with arrangement modes of straight, staggered (most common) and diagonal rows.
Hole Shape: Conventional shapes include circular, square, rectangular, slotted and hexagonal; customized shapes include diamond, plum blossom, five-pointed star and irregular decorative holes. Circular holes are most widely used with strong adaptability.
Open Area Ratio: 5%–60% (adjustable). It directly affects ventilation, light transmission and filtration—higher ratio for better ventilation/light transmission, lower ratio for higher structural strength.
Tolerance Range: Sheet thickness ±0.05mm–±0.2mm; hole diameter ±0.03mm–±0.1mm; overall dimension ±1mm–±3mm (adjustable, with upgradeable accuracy for precision needs).
1.3 Material Selection
Materials are selected based on application environment (corrosion, high temperature, load-bearing). Common options:
Stainless Steel (Most Widely Used): 304, 316, 316L. Features excellent corrosion, high-temperature and rust resistance, suitable for outdoor, humid, acid-base environments (chemical, marine, food processing).
Carbon Steel: Q235. Cost-effective with high strength, suitable for indoor dry environments and non-load-bearing scenarios; corrosion resistance can be enhanced by surface treatment.
Galvanized Steel: Hot-dip/electro-galvanized. Galvanized layer improves corrosion resistance vs. ordinary carbon steel, suitable for outdoor fences and municipal facilities.
Aluminum Sheet: Lightweight, ductile, corrosion-resistant and aesthetic, suitable for decoration, aerospace and automotive industries requiring light weight and good appearance.
Copper Sheet: Excellent electrical/thermal conductivity and corrosion resistance, suitable for electronic equipment, chemical industry and high-demand decorative fields.
1.4 Color Selection
Color is determined by surface treatment, with conventional and customized options to meet decorative and functional needs:
Conventional Colors: Silver (stainless steel/aluminum original), gray (galvanized), black, white, grayish blue, red (powder coating), widely used in general industrial and construction scenarios.
Custom Colors: Custom powder coating, anodizing or spray painting based on customer’s Pantone code or sample, matching project design (architectural facades, interior decoration).
1.5 Applications
Widely used in industry, construction, decoration and environmental protection. Specific applications include:
Construction Field: Building facades, ceilings, partitions, sunshades, sound barriers, stair railings, exterior decoration—improves building aesthetics and practicality.
Industrial Field: Machine guards, filters, sieve plates, ventilation grilles, noise reduction equipment, conveyor screens—used in chemical, pharmaceutical, food, metallurgy industries.
Decoration Field: Indoor ceiling/wall decoration, furniture accessories, exhibition layout, advertising signs—creates unique decorative effects.
Environmental Protection & Municipal Field: Sewage treatment filters, garbage screening, municipal green fences, road sound barriers, public facility decoration.
Other Fields: Automotive parts, aerospace components, electronic casings, household appliance filters—meets special functional needs.
II. Expanded Metal Mesh
Expanded Metal Mesh is a versatile, durable product made by slitting and stretching metal sheets into a uniform, stable mesh. Integrating strength, ventilation and aesthetics, it is widely used in industrial, architectural and daily scenarios. Below is a detailed introduction to its features, specifications, materials, colors, applications and key parameters.
2.1 Product Features
2.1.1 Specifications
Specifications are flexible and customizable. Key parameters: mesh size, sheet thickness, mesh width and length:
Mesh Size: 3mm×6mm–50mm×100mm (long×short). Adjustable—smaller meshes for filtration, larger for ventilation and protection.
Sheet Thickness: 0.3mm–6.0mm. Thinner for light-duty scenarios (decoration), thicker for heavy-duty protection and load-bearing.
Mesh Width & Length: Standard width 1000mm–2000mm, length 2000mm–6000mm; customizable per customer orders.
2.1.2 Material
Materials are selected based on application environment and performance requirements. Common options:
Mild Steel (Q235): Most widely used, high strength, good ductility, cost-effective—suitable for general industrial/architectural uses (fencing, platforms, walkways).
Stainless Steel (304/316): Corrosion-resistant, rust-proof, high-temperature resistant—ideal for harsh environments (chemical plants, food facilities, coastal areas, medical equipment).
Aluminum Alloy: Lightweight, corrosion-resistant, easy to process—suitable for decoration, aerospace and automotive industries requiring weight reduction.
Galvanized Steel: Hot-dip/electro-galvanized mild steel, enhanced corrosion resistance and service life—widely used in outdoor fencing, agricultural greenhouses and transportation facilities.
2.1.3 Color
Color is mainly determined by surface treatment. Common colors:
Natural Finish: Base material’s original color (stainless steel silver, mild steel gray, aluminum light silver).
Galvanized Color: Silver-gray after hot-dip galvanizing, uniform and bright.
Powder Coated Finish: Customizable (black, white, gray, blue, red, green). Wear-resistant, scratch-resistant, strong adhesion—suitable for decorative and outdoor use.
