Product Description
Zinc Coated (galvanized) Steel Chain Link Fence Fabric
Complies with Standard Specification for Zinc-Coated Steel Chain-Link Fence Fabric to ASTM A392, for high security protective fencing.
When covering the same area, this is undoubtedly the most cost-effective fence, and has a high tensile strength of 2170 lbf (9650 N), flexibility, and can be combined with barbed wire and razor wire to upgrade the protection level, It is suitable for highway fences, thermal power plant fences, various government projects, and fences to protect deer and other animals. It is also suitable for installation on slopes and can be cut arbitrarily.
Custom-made chain link fence fabric can be up to 12ft (3.66m) high, but chain link fences can be installed up to 20ft (6.1m).
For the part of the edge of the chain link fence, we can choose the knuckled edge or the twist edge. Easy to maintain and repair, any damaged parts can be replaced quickly.
In addition, if you want a private protection, then we can match the fence with privacy slats, any color, any combination, a combination of beauty and security and privacy protection.

Extension Arms
Dimensions and Tolerances
The extension arms are made out of galvanized steel section has an equal angle profile which is bolted on the I Beam post with a set of 3 nut and bolts (M8 mushroom headed bolts with breakable nut). Each angle has slots for holding the barbed wire Or runner razor wire.
Length of each arm is approximately 450mm.
Extension arms are Hot Dip Galvanized, hence, has a zinc coating of 70 - 80 microns.
Two number extension arms form a V groove above the post to support the concertina razor wire
