Raised expanded metal fence.
EnZar®
Types
- Raised expanded metal fence. Expanded metal as it comes from the press after being simultaneously slit and stretched having the strands and bonds form a uniform angle to the original plane of the solid sheet from which it was formed creating an open mesh diamond making one continuous panel that cannot unravel.
- Flattened expanded metal fence. Expanded metal which has been cold rolled leaving a flat, smooth surface.
For improving the high strength, anti-climb and anti-thieves properties and retrofits of ornamental pickets and previous expanded metal fence, it can be designed into following four types:
- Chain link fence and expanded metal fence.
- Ornamental picket fence and expanded metal fence.
- Retrofits of expanded metal fence.
- Expanded metal fence construction
Expanded metal fence is installed with rails including top, bottom, and intermediate rails for adding strength and security of expanded metal mesh panels. Top rail should be installed with 8 in. below the top of the expanded metal mesh panel and the bottom rail should be installed with 8 in. above the bottom of the mesh panel. Construction of an expanded metal fence greater than 10 ft in height requires an intermediate rail.
When two panels are stacked to reach a required height, the upper panel shall overlap the lower panel and be secured to a rail.
In addition to our standard fence, we can design different types according to your use, such as expanded mesh fence with barbed wire, razor wire or bending top.

Advantages
- High security. Expanded metal fence can control access to protective places and become barriers such as anti-ram vehicle barrier, perimeter barrier and portable barrier.
-
Anti-corrosion. Expanded metal fence has three classes:
- Class 1—uncoated
- Class 2—hot-dip zinc coated (galvanized)
- Class 3—Corrosion-resisting steel
Especially class 2 and class 3 have high anti-corrosion performance.

Applications
Expanded metal fence systems for applications:
- Commercial facilities
- Industrial facilities
- governmental facilities
- institutional facilities
- where the possibility of malevolent incursion
However, this type of fence system is not recommended for residential or public recreational facilities such as pools, schools, and kindergartens.
In addition, expanded metal fence can be used for construction of new expanded metal fence systems and retrofit of chain link fences and retrofit of ornamental picket fence.
