Why Choose Expanded Metal Mesh?
Durable and Versatile for Construction, Civil Engineering, Transportation & Architectural Applications
Expanded metal mesh is one of the most versatile sheet materials available, providing exceptional strength, durability and ventilation from a single piece of metal. Manufactured by simultaneously slitting and stretching a metal sheet, expanded metal creates a rigid mesh with no welds, no woven joints and minimal material waste, making it an economical and sustainable choice for countless applications.
At F.H.Brundle, we stock one of the UK’s largest ranges of expanded metal mesh in mild steel, galvanised steel, stainless steel and aluminium, available in a wide selection of mesh patterns, sheet sizes and thicknesses. Whether you’re specifying materials for infrastructure, fabricating security screens or creating striking architectural façades, our extensive stock and nationwide distribution help keep projects moving.
What Is Expanded Metal?
Expanded metal mesh is produced by cutting and stretching a solid metal sheet in a single manufacturing process. Unlike welded wire mesh or woven mesh, the finished product remains one continuous piece of metal, providing excellent structural integrity and consistent strength across the sheet.
The distinctive diamond-shaped openings offer an ideal balance between:
• High strength-to-weight ratio
• Excellent airflow and visibility
• Slip resistance
• Natural drainage
• Impact resistance
• Long service life
• Reduced material waste during manufacture
Depending on your project requirements, expanded metal is available as:
• Raised expanded metal
• Flattened expanded metal
• Mild steel
• Stainless steel
• Aluminium
• Various mesh apertures and strand widths
Why Choose Expanded Metal Mesh?
Outstanding Strength
Because expanded metal is formed from a single sheet rather than welded together, it offers excellent rigidity while remaining relatively lightweight.
Cost-Effective
The expanding process creates minimal manufacturing waste, making expanded metal an economical solution compared with many fabricated alternatives.
Excellent Ventilation & Drainage
The open mesh design allows free passage of:
• Air
• Light
• Water
• Heat
• Sound
making it suitable for flooring, screening, enclosures and façade applications.
Low Maintenance
Galvanised, stainless steel and aluminium options provide excellent corrosion resistance for demanding indoor and outdoor environments.
Easy to Fabricate
Expanded metal can be cut, welded, bent and framed to suit bespoke fabrication projects.
Expanded Metal Applications
Construction
Expanded metal mesh is widely specified throughout the construction industry because it combines structural performance with low weight.
Typical construction applications include:
• Safety barriers
• Plant enclosures
• Machine guarding
• Brickwork reinforcement
• Ceiling panels
• Partition screens
• Walkways
• Catwalks
• Stair treads
• Mezzanine flooring
• Ventilation panels
• Security doors
Its high strength and open area make it particularly suitable where visibility and airflow are required without compromising durability.
Civil Engineering & Transportation
Infrastructure projects demand materials capable of performing in challenging environments.
Expanded metal mesh is commonly used for:
• Bridge screening
• Highway fencing
• Rail infrastructure
• Noise barrier systems
• Protective enclosures
• Drainage covers
• Access platforms
• Maintenance walkways
• Equipment cages
• Ventilation grilles
• Plant protection
Galvanised and stainless steel options provide long-term corrosion resistance in exposed environments.
Architectural Applications
Architects increasingly specify expanded metal because it combines functionality with contemporary aesthetics.
Applications include:
• Building façades
• Feature cladding
• Solar shading
• Privacy screening
• Balustrade infill panels
• Decorative ceilings
• Interior partitions
• Parking structure screening
• Landscape features
• Public realm installations
Different mesh patterns, finishes and materials allow architects to balance transparency, light transmission and visual impact while maintaining durability.

Raised vs Flattened Expanded Metal
Raised Expanded Metal
Raised mesh retains the original three-dimensional profile created during expansion.
Benefits include:
• Superior slip resistance
• Increased rigidity
• Excellent drainage
• Ideal for industrial flooring and walkways
Flattened Expanded Metal
Flattened mesh is cold rolled after expansion to produce a smooth surface.
Advantages include:
• Cleaner appearance
• Easier fabrication
• Better for architectural projects
• Ideal for screening and infill panels
Compare Expanded Metal Options
Expanded metal is available in a range of materials, profiles and configurations to suit different performance and design requirements. The right specification depends on factors such as strength, corrosion resistance, slip resistance, weight, appearance and intended application.
Which expanded metal material should you choose?
• For economical industrial applications: Mild steel
• For external and infrastructure applications: Galvanised steel
• For corrosive or hygiene-sensitive environments: Stainless steel
• For lightweight architectural and transport applications: Aluminium
Which type of expanded metal should you choose?
Choose raised expanded metal when slip resistance, drainage and rigidity are priorities, particularly for flooring, walkways, catwalks and stair treads.
Choose flattened expanded metal when appearance, smoothness and ease of fabrication are priorities, particularly for architectural screening, façades, partitions and infill panels.
