High quality galvanized expanded mesh / pulled plate expanded wire mesh
Expanded metal mesh is a rigid piece of metal that has been slit and drawn into an open mesh pattern in a single operation. It is stronger, lighter in weight, and more rigid than the original base metal. Conventional mesh is typically formed in a diamond pattern, though other patterns like hexagonal, round, and triangle are available.
Expanded metal mesh is a multipurpose and economical product. It is widely used in:
- Architectural: Stairs, ceilings, walls, floors, and sound absorption.
- Industrial: Conveyors, filters, EMI/RFI protection, and machine guards.
- Security: Window guards, security walls, doors, and fencing.
- Automotive: Speaker grills, diffusers, and muffler guards.
Flattened expanded metal is produced by passing standard expanded metal through a cold rolling mill. This process reduces the thickness and provides a smooth, flat surface. It is ideal for furniture, greenhouse benches, and applications where a lightweight, non-scratch surface is required.
Frequently Asked Questions
What is the difference between standard and flattened expanded metal?
Standard expanded metal has a raised surface with a diamond pattern. Flattened expanded metal is cold-rolled to create a smooth, flat surface that is thinner and slightly longer than the original sheet.
What materials can be used for expanded mesh?
We utilize various materials including carbon steel, stainless steel, galvanized steel, aluminum, aluminum foil, lead, nickel, titanium, and aluminum-magnesium alloys.
Is expanded metal mesh stronger than the original base plate?
Yes, the expansion process creates a mesh that is lighter in weight yet more rigid and stronger than the original base metal due to the structural integrity of the diamond trusses.
What are the common hole shapes available?
While the diamond pattern is conventional, we also provide hexagonal, round, square, rectangular, and scale-like openings based on custom requirements.
What surface treatments do you offer?
Common treatments include hot-dip galvanizing, powder coating, PVDF (fluorocarbon spraying), and polishing to enhance durability and corrosion resistance.
How is the product typically packaged for transport?
Products are secured using wooden pallets with waterproof cloth, wooden cases with waterproof paper, or in rolls with woven bags, depending on the mesh type and size.
