A Down Scale Stops Every Load
An aggregate operation sells by the ton, and every ton crosses the scale. When the truck scale goes down, trucks stack up at the scale house and back into the road. Loads go out on estimated weights, or they don’t go out at all. When a scale drifts instead of failing, nobody notices. A scale reading 0.5% light on a site shipping 500,000 tons a year gives away 2,500 tons. System Scale sells, installs, services, and certifies the scales your yard depends on, with a 4-hour on-site response when one goes down.What We Cover
Every Scale on Your Site
Every piece of equipment on this list is one our technicians install and service. Need something that isn’t listed? Ask. If it’s outside what we do, we’ll tell you before we quote it.
Scale House & Truck Scales
Pit and above-ground truck scales with concrete or steel decks, digital load cells, junction boxes, and indicators. Built and maintained for overloaded axles, washout, and freeze-thaw.
Rail Loadout
Static and in-motion rail scales for loading cars to target weight without overloading a car or leaving tons on the track.
Silos, Hoppers & Batching
Weigh modules and load cells under silos, hoppers, and batch plants, so inventory and mix designs match what was actually loaded.
Unattended Scale Houses
Driver kiosks, RFID readers, traffic lights, remote displays, and ticket printers that move trucks across the scale without an operator handling every load.
Data & Ticketing
Indicators and software that send ticket data straight to your office, including long-range radio links for scales too far out to cable.
Quality Control Lab
Lab balances and moisture analyzers for gradation and moisture testing. Scale calibration is ISO/IEC 17025 accredited at all 27 System Scale locations.
How We Work
4-Hour On-Site Response
When the truck scale goes down, the clock starts for you and for us. Our technicians are on site within 4 hours, find the root cause instead of swapping parts until it works, and test the scale before they leave. If a rebuild takes longer, a rental truck scale keeps you loading.
One Partner for Every Pit and Plant
Most aggregate producers run more than one site, and each one tends to end up with its own scale vendor, its own records, and its own surprises. We work from 27 locations across 10 states, so one partner can cover your quarries, pits, and asphalt plants on one preventative maintenance schedule with one set of records.

Certified Before the First Load Leaves
Every service call ends with the scale tested, with as-found and as-left readings on the record so you can see what changed and by how much. Certificates and due dates live in CalVault, so a state inspection or a customer weight dispute pulls from one place instead of five inboxes. Check our master scope before a bid, an audit, or a customer file request.

The Technician Servicing Your Scale Has
Equity in Getting It Right.
System Scale has been employee owned since 1995. That’s not a trivia fact. It defines how we do business. We aren’t a PE roll-up and we aren’t building to sell. The technician servicing your scales is an owner, not a rotating contractor.
Continuity. You get the same technicians on your site, not a rotating dispatch queue. They learn your scale house, your haul roads, and your busy season.
Retention. Employee ownership creates stability. Our technicians stay longer, learn your sites, and become more effective over time.
Independence. We are not building to sell. You do not have to worry about an acquisition changing your pricing, service model, or relationships overnight.
Questions
Aggregate Scale FAQ
How often should a truck scale be serviced?
Your state weights and measures program sets the minimum for legal-for-trade scales. High-traffic aggregate scales usually need more than the minimum. We set a preventative maintenance schedule based on your tonnage and site conditions, then adjust it based on what we find each visit.
What causes truck scale failures at aggregate sites?
The usual causes are lightning and power surges, water and debris in the pit, corroded junction boxes and cables, cracked decks, and load cells pushed past their rating. Most repeat failures trace back to one of these. We fix the root cause, not just the part that failed.
Is System Scale ISO/IEC 17025 accredited?
Yes. All 27 System Scale locations are ISO/IEC 17025 accredited for scale calibration, and our dedicated calibration labs carry a broader scope of accreditation for other instrument types. Our full scope and certificate are posted on our scope of accreditation page.
How fast can you get a technician to a down scale?
We commit to a 4-hour on-site response. Our technicians work from 27 locations across 10 states, so most aggregate sites in our footprint have an office close by.
Can you automate our scale house?
Yes. Driver kiosks, RFID, traffic lights, remote displays, and ticketing software let trucks weigh in and out without an operator handling every load. One Indiana aggregate producer ended a line of trucks backing into the road by replacing an obsolete indicator in about two hours.
What if our scale is too old to repair?
We’ll tell you. We quote a repair when a repair makes sense and a replacement when it doesn’t. If you need to keep loading during a replacement, ask about a rental truck scale.
Where do our calibration records live?
In CalVault, our customer portal. Certificates and due dates for every site, in one place, ready when an auditor asks.
Talk to an owner
Talk to an owner about the scales on your sites. Tell us how many locations you run, what’s on the ground, and what’s been breaking. Every technician who picks up the phone has equity in keeping your trucks moving. We’ll tell you exactly what we can do, and what we can’t.
