The Impasse™ Security Fence (Above) was designed and engineered to meet the expressed needs of security specialists, consultants and engineers - the need for a value added security fence that delayed forced entry for a time period sufficient to bring secondary security measures into play. To make the Impasse™ system an even more relevant answer to physical security demands, the base design was configured to be easily accessorized with added anti-ram barrier capability and anti-climb inserts, as well as sensor and alarm systems. The high-strength architectural shapes of Impasse™ components were enabled by the high-speed automation of Ameristar’s in-house roll-forming mill. Ameristar’s unique PermaCoat®(double layer) electrostatic powder coating process ensures an appearance that remains aesthetically pleasing for many years. Impasse™ is available in three different styles (triple-pointed, blunt-tipped, and outwardly curved) and four standard colors (black, white, bronze, and desert sand).

Mini-Mesh (Shown Right)

When higher security is required mini-mesh, expanded metal, and welded wire are just some of
the options to consider for fencing materials.

Mini-mesh is a very heavy duty, tightly
woven chain-link fence that has no toe holds for climbing, can't be easily crawled under, and the weave is too small for bolt cutters

It's simple: the thicker the metal wire or tighter the weave, the more difficult it is to climb and the more time consuming it is to cut. Mini-mesh is a very heavy duty, tightly woven chain-link fence that has no toe holds for climbing, can't be easily crawled under, and the weave is too small for bolt cutters.

Thicker gauge pipe should be used as end posts, line posts and top rail to support the added weight of mini-mesh or even heavier fence fabrics.

Expanded Metal Mesh
(or Diamond Mesh - Shown Left) is available in both medium and high security grades. It is made from special carbon steel,, stainless steel, or aluminum to increase tensile strength, with diamonds small enough that it is virtually impossible to cut, climb or crawl under.

The primary purpose of expanded metal mesh is to create a physical perimeter barrier.

Basically, expanded metal is a solid sheet of steel that is simultaneously slit and stretched into a rigid, non-raveling open mesh whichtakes as many as 72 individual cuts to create a 36" hole.

Epanded metal mesh can be used to retrofit existing chain-link fence by covering the chain-link fabric with the expanded mesh. Depending on wind conditions, the existing framework may be strong enough to support the new mesh although some additional support may be required.

Expanded metal mesh is primarily specified as hot dip galvanized finished but it is also available with vinyl or powder coating and in black, green and brown.

Razor Ribbon and/or Barbed Wire
and other deterrents make climbing a fence far more difficult and mentally intimidating. Intrusion and motion sensor technology can also be designed into a fence system to help alert security personnel of a potential breach in
secured perimeters.

The use of razor ribbon, razor tape
and razor coils with barbed wire and other deterrents make climbing a fence far more difficult and mentally intimidating.

Razor Wire Offers the ultimate in security for indoor and outdoor property protection.  Commonly used to enhance entry deterrence to chain link fencing, warehouses, enclosures, rooftops, prisons, and valued inventory control.
