ESD flooring in Greenville, to 2.5 x 104 to 1.0 x 106 ohms
Aerospace ESD requirements arrive as contract language flowed down from a prime, so in Greenville the audience for your resistance records is somebody else's auditor. The record here: aerospace/avionics MRO and integration.
What is actually in Greenville
Airframe, avionics and space hardware work around Greenville is where the requirement originates, each operation against a named source.
L3Harris' Greenville, Texas aerospace center spans 3.7+ million sq ft
L3Harris' Greenville, Texas aerospace center spans 3.7+ million sq ft (manufacturing, multi-sensor testing, anechoic testing, aircraft painting, and an FAA-approved flight-test range); it delivered the first MC-55A aircraft to the U.S. Air Force in January 2026 and modified King Air 350ER aircraft for Canada's MAISR program.
The customer is the auditor
On a Greenville program the deliverable is evidence as much as coating, because the records have to survive an audit run by somebody outside your building.
The document behind a Greenville job
ANSI/ESD S20.20-2021 is the one worth reading first for work like this. Sets the requirements for an ESD control program, and with it the system level thresholds a qualified floor has to support.
What it actually governs
S20.20 is a program standard, not a product standard. It tells an organisation that handles ESD sensitive electrical or electronic parts how to run a control program: what has to be qualified, what has to be verified, and how often. Flooring is one item inside that program, which is why the standard sets a system threshold rather than a floor specification.
Questions from Greenville
What records should we insist on at closeout?
Product data for the system installed, the surface preparation profile, moisture readings taken before installation, a grounding drawing, and the resistance readings mapped to floor locations. Name that package in the specification or it tends not to exist.
How soon can you get to Greenville?
Tell us the timing you are working against and we will give you a real date rather than a placeholder. Crews work Hunt County alongside the rest of the Texas schedule. Send the details.
Do you handle the whole job in Greenville or just the coating?
The whole job: removing what is down, preparing the slab, the grounding network, the system itself and the cure schedule around your operation. Prep and grounding are where most of the work is. How it runs.
