The Security is the industrial-grade fence in the line: a no-climb picket with an outwardly curved spear top.
Powder-coated smooth- A no-climb picket
The spacing and the rail positions are set so there is nothing to get a foot on.
- An outward-curved spear top
The curve points away from the property, which is what makes going over it a different proposition.
- A visual deterrent
Catalyst's own framing: the imposing style discourages climbing and reads as a deterrent before anyone tries.
- Heights to 9 feet
Six, seven, eight and nine feet, taller than anything else in the line.
- No visible hardware
The NoVis™ hidden fastener system locks the panels together on level and sloping ground without visible screws.
- A finish that is baked on
Every aluminum component is powder coated before assembly, so there are no bare spots, and SolarGuard® keeps the color from fading.
- Made by Catalyst, installed by us
Catalyst Fence Solutions manufactures the Security, and the image above is its product visualization, not a photograph of a Chonko Construction job. We are the installing builder.
The Security is offered in one tier and three colors.

Heights 6, 7, 8 and 9 feet. Catalyst lists additional finishes through a sales representative.
- checkPanel widths. 6 and 8 feet. Walk gates and drive gates are built to match the panel, and we set post depth and spacing to the height you choose.

- Pickets
- Square pickets with the no-climb spear top, spaced and set so there is nothing to stand on.
- Rails
- Rails positioned for the no-climb build rather than for looks, which is what closes the footholds.
- Posts
- Aluminum posts sized to the height, with heavier gate posts, set in concrete footings.
Post caps and rail accents are a choice, not a default.
- check_circle
Three aluminum caps. Flat Top, Ball and Solar.
- check_circle
Three finials. Triad, Quad and Fleur-de-lis finials sit on the post in place of a flat cap.
- straighten
Rail adornments. Butterfly scrolls and circles mount into the rails themselves, which is what separates a decorative aluminum run from a plain one.
- check_circle
The solar cap lights the line. Catalyst's Solar Post Cap puts off-the-grid landscape lighting on the posts, with no wiring to run.
- check_circle
Pick it with the style. The cap is the part of the fence you see at eye level from the house. We price the caps with the panels, so it is one number rather than a change order later.
For the Security, the number moves with linear footage first, then the height you choose (6 to 9 ft), the gates, and the ground the posts go into. The full breakdown of what moves an aluminum fence price is on the aluminum fence page; we set the exact figure in writing after we walk the property.
Want real numbers? Our aluminum fence cost guide breaks down what an aluminum fence runs per linear foot in the Midlands, and the all-materials fence cost guide compares it to the other fence types. Whatever your number, it is set in the contract before any post hole is dug.
Warranty and Who Installs It
Two warranties cover a Security we install.
Catalyst backs its fence with a transferable limited lifetime warranty; the warranty document carries the terms.
Chonko Construction is a licensed home builder, license #52210, and the installation carries our named workmanship warranty.
Licensed South Carolina home builder, SC Residential Builders License #52210. One contract covers the panels, the posts, the gates and the installer.
Aluminum in the Midlands
Aluminum is the low-fuss fence for the Midlands.
- Humidity. Aluminum does not rust, and the powder coat is baked on.
- Heat. Summer heat does nothing to it.
- Wind. Open pickets let storm wind through, so the panels carry less load than a solid fence, and the posts are set in concrete to hold the line.

Frequently Asked Questions
What makes a picket no-climb?add
The rail positions and the picket spacing leave nothing to stand on, and the top curves outward. It is a design, not an accessory.
How tall does the Security go?add
Six, seven, eight and nine feet. It is the tallest style Catalyst offers.
Is this only for commercial sites?add
It is built for them, and it goes on residential property where the situation calls for it. On a home we usually talk through whether the look fits the street first.
What is a aluminum security fence?add
The Security is the industrial-grade fence in the line: a no-climb picket with an outwardly curved spear top. The Security is Catalyst Fence Solutions' version of it, and Chonko Construction installs it across Columbia and the Midlands under one written contract.
What heights does the Security come in?add
6 to 9 ft. We match the height to the job: privacy and pool code want the taller end, a front-yard boundary usually wants the shorter.
Can the Security be installed on a slope?add
Yes. On a grade we rack or step the panels so the fence follows the slope and stays level, and we show you which approach fits before any post is set.
Which colors does the Security come in?add
3 colors: Black, Bronze, White. Ask which are quick-ship, because it changes the start date.
