Expandable grill metal mesh for window screen
Expandable Grill Metal Mesh
Expandable Grill Metal Mesh is a sliding and stretchable metal mesh system designed for window protection. It combines security, ventilation, and flexibility in one structure.
Unlike fixed welded mesh, this expandable design allows the mesh to be adjusted to different window sizes, making it highly suitable for residential, commercial, and industrial applications.

Why choose our expanded metal mesh?
This stretchable metal mesh can be smoothly stretched and folded, achieving linear expansion and contraction without deformation.
Suitable for various window sizes, it reduces inventory complexity for wholesalers and allows for faster on-site installation.
Made of thick steel plate or stainless steel, it unfolds to form a sturdy barrier with a structure that evenly distributes stress.
Its impact resistance is far superior to standard insect screens, making it suitable not only for filtration but also for security applications.
Even when fully extended, the mesh structure remains open, providing 30-60% open area.
It maintains indoor air circulation and is suitable for hot climates.
Available surface treatments include galvanizing (protecting steel from oxidation) or powder coating (adding an extra layer of protection).
Under normal outdoor conditions, galvanized coating can extend the service life of steel by 2-5 times compared to untreated steel.
When not in use, the mesh cover can be completely folded to one side. The scissor-lock design allows for compact stacking without damaging the structure.
Easy to store and convenient for everyday use.
