Security Gate Co: Your Security, Our Strength

Security Gate Company manufactures the "classic" design of folding gate that has been around for years, and proven over and over to be durable and dependable. Our folding steel gates are made of 3/4" wide 14 gauge steel channel, riveted back to back with solid steel rivets. Solid steel rivets provide abundant strength to last longer under any conditions. We use 1-1/2" x 1-1/2" x 1/8" thick hot rolled angle iron for upright gate rails, that resist abuse and last longer than thinner alternatives. Our drop pins are made of 5/8" round rod and our casters are hard rubber. We thoroughly coat our gates using black enamel paint.

Applications for Folding or Accordion Gates

Folding security gates are used by manufacturing and warehouse facilities, retail and distribution centers, education and health care institutions and in homes and office buildings. Security Gate Company supplies gates in standard sizes from 4-1/2' wide by 5-1/2' high single gates to 16' wide by 8-1/2' high double gates. We also make custom size single and double gates up to 10' high. Call for quotes on custom sizes. We carry door gates for openings 24" to 48" wide in heights from 61" to 83" and portable gates 6 and 12 feet wide. Portable, Aisle and Pet Gates are a perfect temporary or mobile security gate for many applications.

More Than 40 Years of American-Made Security Gates

Security Gate Company is a manufacturer of steel folding security gates based in DeKalb, Illinois. Since the early 1980s, we've built every gate in our facility using heavy-duty 14-gauge steel channel, solid steel rivets, and hot-rolled angle iron uprights — the same proven construction that has made our gates a trusted choice for businesses and homeowners across the country.

We make folding gates for just about every application. Our door gates fit standard openings from 24" to 48" wide, while our single and double folding gates cover spaces up to 16 feet. Need something bigger or a non-standard size? We build custom gates up to 10 feet tall. We also carry portable gates for temporary crowd control and steel pet gates for use at home.

Every gate we sell is designed to fold flat and pivot out of the way when not in use, so you get strong access control without permanently blocking a doorway or aisle. They accept standard padlocks, and we can advise on the best lock pairing for your security needs.

Whether you're securing a warehouse dock door, a retail storefront after hours, a school hallway, or a room in your home, our gates deliver dependable protection at a competitive price

Security Gates for Every Application

From factory floors to storefronts, our steel folding gates protect what matters most. Here's how businesses and homeowners put our gates to work.

Warehouses & Loading Docks

Keep dock doors and receiving areas secure between shifts without blocking airflow or forklift access. Our double folding gates cover openings up to 16 feet wide and swing completely out of the way during active operations. Drop pins and padlock hasps provide reliable lockdown when the dock goes quiet.

Retail & Storefronts

Protect inventory and deter break-ins after hours while keeping your storefront visible from the street. Our single and double gates install behind glass or inside doorways and fold flat when you open for business. The open lattice design means passersby can still see your displays.

Schools & Institutions

Control foot traffic in hallways, restrict access to wings during off-hours, and section off cafeterias or gymnasiums. Our portable gates roll into position when needed and store easily in a closet. Door gates fit standard institutional openings from 24" to 48" wide.

Homes & Apartments

Add a layer of security to patios, garages, basement entries, or interior rooms. Our door gates and single gates pivot 180° out of the way when not in use, so they never block your daily routine. We also make steel pet gates built with the same heavy-duty construction as our commercial products.

What Clients Say About Us

Why Choose Security Gate Company?

How to Choose the Right Folding Security Gate

Not sure which gate you need? Follow these four steps.

Measure Your Opening

Measure the width and height of the space you need to secure. Door gates fit openings 24" to 48" wide. Single gates cover up to 7.5 feet. For anything wider — dock doors, overhead doors, storefronts — a double gate handles openings up to 16 feet. Need something outside those ranges? We build custom sizes up to 10 feet tall.

Choose Your Gate Type

If the gate needs to secure a standard interior door, go with a door gate. For single-sided openings like a patio or garage bay, choose a single gate — it mounts on one side and pivots open. For large two-sided openings where trucks or equipment need to pass through, a double gate splits in the middle so both halves swing out of the way. If you need something temporary or movable, our portable gates roll on casters and fit through standard doorways for easy storage.

Think About Mounting

All our gates can be mounted inside the door jamb for a flush look or face-mounted on the outside. Single and door gates have reversible hinges so you can mount on the left or right. Double gates come with optional H-brackets for top support and extended brackets if installing inside an overhead door opening.

Pick Your Lock

Every gate includes a locking bar and is set up for a standard padlock. For higher security, consider a shrouded padlock or disc lock that resists bolt cutters. Industrial sites should look at hardened steel shackle locks with at least a 10mm diameter. Not sure which lock fits your situation? Give us a call and we'll help you match the right lock to your gate.
