1. "Secure Wall" High Security Fence System * Patent Pending * Created and Fabricated by: South Lyon Fence Co., Inc.

2. Today’s market demands a cost effective solution to a familiar problem ……THEFT and SECURITY With poor economic times and high dollar returns on scrap metal, the days of standard chain link fence security are coming to an end. With poor economic times and high dollar returns on scrap metal, the days of standard chain link fence security are coming to an end.

3. Existing Chain Link Fence Systems Using commercial grade chain link with barb wire is posing little or no security to would be thieves with an inexpensive pair of bolt cutters. Using commercial grade chain link with barb wire is posing little or no security to would be thieves with an inexpensive pair of bolt cutters.

4. Existing Chain Link Fence System Standard chain link fence systems are constructed using nuts and bolts, which allows the fence to be disassembled with common tools. Most of your stations are un-manned, and tucked out of sight, allowing the time needed by thieves to cut through and gain access.

6. Considerations for Design 1. Penetration – We wanted to find a material that could not be cut with bolt cutters or disassembled with common tools. (There are no fasteners on this fence) 1. Penetration – We wanted to find a material that could not be cut with bolt cutters or disassembled with common tools. (There are no fasteners on this fence) 2. Non-Climb – Top of fence is secured by adding Barb Wire and Razor Ribbon. 2. Non-Climb – Top of fence is secured by adding Barb Wire and Razor Ribbon. 3. Visibility – First line of defense against intruders is to have them stop and ponder the unexpected of what might be behind the wall. 3.

9. Post Installation As a standard, the post are 3” square or round galvanized steel. As a standard, the post are 3” square or round galvanized steel. All post are to be set in concrete footings. All post are to be set in concrete footings. The post spacing is determined by the height of the fence. (ex. 10’ high = 5’ on center) The post spacing is determined by the height of the fence. (ex. 10’ high = 5’ on center)

10. Rail Installation Once the posts are set and level, the next step is to weld the rails to the post. After experimenting with several applications, we have found that the square rails can easily be welded to existing round post without sacrificing the stability of the Fence.

11. 16 Ga. Panel Installation The panels are made of 16 Ga. galvanized steel. The 4” Boxed Ribbed style panel offers superior strength and a pleasing look to the wall when painted or left galvanized. The panels overlap and are welded together as one solid wall, which are then welded to the rails. The panels are made of 16 Ga. galvanized steel.
