Houston manufacturing plants lose material at 4 points: the employee gate at shift change, the shipping dock, the material yard and the fence line after dark. Reliable Guard & Patrol Service staffs all 4 with licensed officers, unarmed or armed, scheduled around your shifts. We hold Texas DPS license B07315701, and every round our officers walk is GPS-logged. Your certificate of insurance goes out the same day you approve the proposal, and terms start at 1 week.
What changed in plant and freight theft in 2026
Cargo theft losses are climbing faster than the number of thefts, and metal is moving up the list of what gets taken.
Verisk CargoNet counted 2,646 confirmed U.S. and Canadian cargo thefts in 2025, up 18%, while estimated losses rose 60% to nearly $725 million. Metals theft jumped 77% on copper demand. CargoNet’s Keith Lewis tied the jump to criminal groups getting more selective about which loads they hit. By Q2 2026 the gap had widened: 677 incidents, down 26% from a year earlier, against $304.6 million in losses, more than double. Metal thefts rose to 80 that quarter from 54 a year earlier, and copper stayed the most-targeted metal.
Texas carries a large share. It accounted for 20% of U.S. cargo thefts in 2025, second only to California, in Overhaul’s annual cargo theft report. Warehouses and distribution centers were the location in 36% of those thefts, and deceptive pickups, where a thief poses as the carrier, rose 35%.
Houston holds the material. The region’s manufacturing sector produced $126.9 billion in output in 2024, 16.7% of the regional total against 9.8% nationally, and Houston led every U.S. metro in manufacturing output for the 3rd straight year, according to the Greater Houston Partnership’s March 2026 Economy at a Glance. GHP counts more than 7,000 manufacturing establishments here.
For a plant, the exposure sits in the yard. Copper drove the 2025 jump in metals theft and was still the most-targeted metal in mid-2026. A camera records the night it leaves. An officer at the gate with written authority to stop a release changes what happens that night.

The Plant Clock: 3 windows every plant post has to cover
A manufacturing plant is exposed in 3 windows: shift change, freight hours and dark hours. Each fails a different way, so each gets its own post orders, and the schedule runs on your shift times. We call it the Plant Clock and fill it in with you on the first call. It decides where the officer stands at 5:50 a.m. and which fence line they walk at 2:30 a.m.
Window 1: shift change
On a 3-shift plant, every shift change sends 2 crews through the same gate at once, one leaving and one arriving. Badges get waved instead of swiped, and a side door gets propped for a smoke break. Somewhere in that crowd, a lunch cooler goes out heavier than it came in.
Our officer works the turnstile or vehicle gate through the rush: badge to face, 1 person per swipe, contractors and visitors signed out by name. If your written policy calls for exit inspections, the employee opens their own bag while the officer watches, and our guide to how a lawful bag check works covers the legal limits. The officer writes up what happened and calls your shift supervisor. Discipline stays with your HR team.
Window 2: freight hours
Raw material comes in and finished goods go out, often through the same yard gate. The expensive mistake happens on the outbound side, when a trailer of finished product gets released to a driver whose name, tractor or MC number doesn’t match the booking. Our officers record carrier, driver, tractor, trailer and seal before a load moves. The full check is the 5-field pickup log for outbound trailers on our logistics page. Between appointments, the yard gate stays shut.
Window 3: dark hours
Nights, weekends, holidays and shutdown weeks. The floor is empty and the yard is full. The rover walks GPS-logged rounds with fixed checkpoints at the fence line, the scrap bins, the copper and brass cage, the laydown yard and the roof ladders. Every scan carries a timestamp you can audit.
The Plant Clock on paper
Take a 3-shift, 5-day fabrication plant with shift changes at 6 a.m., 2 p.m. and 10 p.m. and trucks moving 7 a.m.-5 p.m. on weekdays. An illustrative Plant Clock for that plant has 3 lines.
- A gate officer works weekdays from 5 a.m. to 7 p.m. and covers the 6 a.m. and 2 p.m. shift changes plus every truck appointment. That’s 70 hours a week, armed or unarmed depending on what the yard holds.
- A rover works weekday nights from 7 p.m. to 5 a.m., walking GPS checkpoint rounds with a fixed stop at the gate for the 10 p.m. shift change. That’s 50 hours a week.
- A rover covers weekends around the clock on the same checkpoint route, and weekday holidays switch to this pattern. That’s 48 hours a week.
Those 3 lines add up to 168 hours, the same as a single 24/7 post. The Plant Clock moves the hours around without adding any: a fixed officer holds the gate while people and trucks cross, and a rover covers the plant while it’s dark. 168 hours is also more than 4 full-time 40-hour schedules before anyone takes a day off, so a gap-free post needs backup officers behind it.
We price the plan per site after the first call. Armed hours cost more than unarmed, so the plan puts armed coverage only where the gate needs it.
Why copper theft is a felony case in Texas
Under Penal Code 31.03(e)(4)(F), stealing aluminum, bronze, copper or brass worth less than $20,000 is a state jail felony. Most other thefts under $2,500 are misdemeanors. So a small bag of brass fittings leaving your gate can be a felony case, as long as the report holds up.
That puts weight on the paperwork. Our reports carry the timestamp of the GPS round that found the problem and the officer’s written account, and they reach you the same shift.
Our published incident log holds 5 stops, all logged after 11 p.m. and before 4 a.m. at construction sites, a vacant building and a distribution warehouse. None of them happened at a manufacturing plant, and we won’t dress them up as plant work. The closest match to a plant yard is the 3:30 a.m. copper stop at a job-site storage container, which ended with a police arrest and the copper recovered.

Plant work we turn down
Here’s what falls outside our plant work, so you can rule us out early.
We don’t provide fire watch. When a hot-work permit calls for one, assign a trained employee or a fire-watch contractor. A gate officer pulled to a welding job leaves the gate open.
We also pass on events, residential and HOA sites, K-9 teams, alarm calls and parking enforcement. Everything we do run is on our Houston security guard services page.
And if your plant runs a single day shift, ships nothing after 5 p.m. and keeps nothing in the yard worth a trailer, a monitored camera system may be all your nights need. We’ll say so on the call.
Setting up a plant post in 4 steps
An unarmed post can usually start the same day.
- A first call. Shift times, gate and dock count, truck windows, what’s gone missing, and your exit-inspection policy if you have one.
- A free written proposal with officer type, Plant Clock hours, draft post orders and the rate.
- A site walk where the layout calls for one. We walk the gate, dock, yard and fence line with you, set the GPS checkpoints and mark your muster point.
- The certificate of insurance goes out the same day, your plant manager signs the post orders, and you get your account supervisor’s direct number.
Billing runs by the week or by the month, for one shutdown or a post with no end date. Nothing holds you past the term you pick.
Armed or unarmed at a plant gate
Most plant posts run unarmed. An armed officer on the gate fits 4 situations: high-value metal in the yard, finished goods that resell fast, a record of violent incidents on the property, or a specific, credible threat.
Unarmed officers hold the Level II (non-commissioned) security officer license. On a plant post they cover gate and badge control, dock and yard checks, GPS-logged patrols and a written report for every incident. Our unarmed security guard services page covers that post in detail.
Armed officers hold a Level III commission. Texas renews it at least every 2 years, and each renewal needs a new firearm proficiency certificate. Details are on our armed security guard services page.
For plants with heavy truck traffic, we often recommend an armed officer on the main gate at peak truck hours and an unarmed rover on the off-shifts, so the armed rate covers only the hours the gate carries the risk. The firearm doesn’t add arrest powers. Both license levels act with a private citizen’s authority.
Before you sign, look up our license, B07315701, on the TOPS license lookup run by Texas DPS, and ask for the license level of every officer assigned to your plant. We give names on request.
Frequently Asked Questions
Can your officers search employees' bags or vehicles at the exit?
Only under your written policy, with the employee’s consent. The employee opens the bag or vehicle and handles the contents while the officer watches and records. If the officer reasonably believes something was stolen, Texas Civil Practice and Remedies Code 124.001 allows a detention that’s reasonable in manner and length to investigate ownership. The officer calls police when a theft is confirmed, and HR handles discipline.
Will you name our company as an additional insured?
Yes, on request. Send the exact wording your contract requires with your first email, and we’ll issue the certificate the same day. Our policies cover general liability, commercial auto and workers’ compensation.
How fast can a plant post start, and is there a minimum term?
An unarmed post can usually start the same day. Terms run by the week or by the month, and the shortest is 1 week.
Can we hire officers for a shutdown week or a reduction in force?
Yes. Weekly terms cover both. Send the dates, shift times and gate count, and we’ll quote the hours.
