Raised & Flattened Expanded Metal Sheet - Stretched Metal Mesh Screen
Expanded metal sheet is a kind of metal mesh screen that has been slit and stretched to form a pattern of uniform openings. This manufacturing process creates a mesh-like structure without any welding or weaving, ensuring strength and durability. Expanded metal mesh, also called expanded metal screen or expanded metal panels, comes in two main forms: raised (standard) and flattened.
- Raised expanded metal mesh has strands and bonds that are elevated above the sheet’s plane, offering excellent strength, rigidity, and skid resistance.
- Flattened expanded metal sheet is passed through rollers to achieve a smooth, level surface while maintaining the same open area, making it more suitable for applications where a flat surface is needed.
Types and Patterns in Expanded Metal Mesh
Expanded metal mesh can be classified by its strand and bond arrangement, opening shape, and finishing:
- By Form
- Raised (Standard) Expanded Metal: strong, slip-resistant, used in walkways, platforms, and security applications.
- Flattened Expanded Metal: smooth surface, used in cladding, partitions, and filtration.
- By Opening Pattern
- Diamond pattern: the most common, offering strength and versatility.
- Hexagonal pattern: provides high open area for ventilation.
- Round pattern: aesthetic applications and lightweight screening.
- By Strand Thickness and Opening Size
- Heavy-duty expanded metal: thicker strands for industrial flooring and heavy load-bearing applications.
- Light-duty expanded metal: thinner strands for decorative, fencing, or filtration purposes.
- By Finish: Mill finish, powder-coated, anodized, painted, or plated depending on functional and decorative requirements.
Materials Used in Perforated Metal Screen
Expanded metal sheets can be made from a variety of materials depending on strength, corrosion resistance, and aesthetic requirements:
- Carbon steel expanded mesh: strong, economical, suitable for structural applications.
- Galvanized steel expanded metal mesh: corrosion-resistant, ideal for outdoor use.
- Aluminum expanded metal screen: lightweight, corrosion-resistant, often used for decorative or architectural purposes.
- Stainless steel expanded metal sheet: high corrosion resistance and strength, suited for harsh environments.
- Copper and brass expanded metal screen: attractive finishes for decorative or specialty applications.
- Titanium and other alloys: for specialized industries like aerospace or chemical processing.
Applications of Perforated Metal Mesh
Expanded metal panels are versatile and widely used across industries:
- Construction & Architecture: façade cladding, sunshades, partitions, balcony railings, ceiling panels, and decorative screens.
- Industrial: walkways, platforms, stair treads, machine guards, and shelving.
- Security: fencing, window guards, enclosures, and protective barriers.
- Filtration & Ventilation: air and fluid filters, grilles, and vents.
- Transportation: vehicle grilles, radiator covers, and ventilation panels.
- Decorative: furniture accents, retail displays, and art installations.
