What makes a piece of shoring equipment last for decades on a demanding job site? While the quality of the steel and the integrity of the welds are essential, there is another critical component that often goes overlooked: the finish. For a tool expected to endure brutal weather, constant abrasion, and heavy impacts, a simple coat of paint can quickly fail. You need a robust, protective finish.
Since 1951, Ellis Manufacturing Company has built its reputation on engineering solutions that perform and last. A core component of that philosophy is our meticulous powder coating process. This isn't just a final, cosmetic step; it's an integral part of how we create equipment you can trust, project after project.
This overview provides a detailed, behind-the-scenes look at our industrial-grade powder coating process. We will show you how we do it, explain why our method creates exceptional durability, and demonstrate what that means for the long-term value and safety of your investment.
What is Powder Coating? A Look Beyond Paint
To understand the powder coating process, it’s best to start with what it is not: it is not paint. While both provide color, they are fundamentally different technologies.
Powder coating is an advanced dry finishing process. Instead of a liquid solvent, it uses a finely ground powder made of polymer resins, pigments, and curing agents. This powder is applied to a surface electrostatically, then cured with heat. This process creates a chemical reaction that bonds the powder together and to the part, forming a hard, durable polymer shell that is significantly tougher than conventional paint

Essentially, paint is a thin layer that sits on top of steel. An Ellis powder coat becomes a fused, integral part of the final metal powder coated product.
How We Do Powder Coating on Metal: Our Three-Stage Process for a Highly Durable Finish
The key to a superior finish that lasts lies in the rigor and precision of the process. While many companies powder coat, the quality of the result depends on the discipline applied. Here is a look at the Ellis process—a three-stage system we have perfected to ensure high-quality durability for our equipment.
Stage 1: Critical Surface Preparation
This is the foundational stage of the entire process. A quality finish can only adhere to a perfectly prepared surface. Any shortcut here can lead to premature failure in the field. Our process is uncompromising and includes multiple steps to ensure the steel is pristine before any coating is applied.
Stage 2: Precision Application
With a perfectly prepared surface, our skilled technicians apply the powder. We use state-of-the-art electrostatic equipment to ensure every part receives a consistent, uniform coating.
The process involves giving the finely ground polymer powder a positive electrostatic charge as it leaves the spray gun. The steel parts are grounded, creating a powerful attraction. The charged powder is drawn to the part, wrapping evenly around every angle, corner, and complex geometry—a feat impossible to achieve with liquid paint. Our quality control team monitors this stage closely to ensure the coating is applied to our exact thickness specifications.
Stage 3: High-Temperature Curing
The final stage is a chemical transformation. The coated parts are moved into a large, high-temperature curing oven where the magic happens. The heat is precisely controlled to melt the powder, allowing it to flow into a smooth, liquid-like film.
As the parts remain at temperature, a process called cross-linking occurs. The polymer resins react and bond together, forming a dense, interconnected molecular chain. This is what gives the final finish its incredible hardness, chemical resistance, and durability. After curing, the parts undergo a final quality inspection before being approved for assembly.
The Proof of Performance: Engineered for a Long Service Life
How Long Does Powder Coating Last? From Decades to a Lifetime
A common question is, "how long does powder coating last?" While many sources cite a general lifespan of 15-20 years, this figure is highly dependent on the quality of the process and the environment. For industrial equipment, a generic answer isn't good enough.
The Ellis powder coating process is engineered to exceed that standard, even in the harsh, unpredictable conditions of a construction site. The meticulous preparation, from grit blasting to the iron phosphate conversion coat, is specifically designed to maximize the lifespan of our products.
Our finish isn't just "good"; it's tested to meet specific, measurable performance criteria that translate directly to a longer, more reliable service life for your equipment.
More Than a Claim: Our Powder Coating Specifications
We believe in transparency and proof. When you invest in Ellis equipment, you are investing in a product that meets rigorous technical standards. Our powder coating specifications are a testament to that commitment.

The Real-World Value: Performance Where It Counts
The Financial Case: Reducing Lifecycle Costs & Boosting ROI
For a contractor, every piece of equipment is an investment. A superior finish translates directly to tangible business value and a lower total cost of ownership (TCO).
An Ellis powder coat significantly reduces the time and money spent on maintenance. You won't be constantly repainting rusted or flaking equipment. This means your tools spend more time on the job site generating revenue and less time in the maintenance yard. The extended service life means a higher return on your initial investment.
The Ellis Standard: A Finish Engineered for Trust
At Ellis Manufacturing Company, our powder coating process is far more than an afterthought; it is an integral part of our engineering philosophy. It is a tangible reflection of our 70-year commitment to providing professionals with solutions of unmatched quality, performance, and long-term value. From the initial blast to the final cure, every step is a deliberate action to build a product you can trust to perform, day in and day out.

Frequently Asked Questions (FAQ)
What types of powder coating does Ellis use?
We primarily utilize high-performance thermoset powders, such as polyester, for their outstanding balance of durability, chemical resistance, and UV stability, making them ideal for equipment used in demanding outdoor environments.
Is powder coating environmentally friendly?
Yes, it is a key advantage of the process. Because it uses no liquid solvents, our powder coating process releases virtually no Volatile Organic Compounds (VOCs). Furthermore, our advanced application booths allow us to reclaim and reuse up to 95% of the powder overspray, dramatically minimizing waste.
Can you paint over a powder-coated surface?
While technically possible, it is generally not recommended. The smooth, non-porous surface of a cured powder coat is designed to resist adhesion, meaning that any paint applied over it is likely to chip and peel easily, resulting in a poor-quality finish. A high-quality initial coating helps eliminate the need for repainting
What products does Ellis offer with this powder coat finish?
Our rigorous powder coating process is applied to our core line of steel products, ensuring they are protected for a long service life. This includes our Heavy-Duty Steel Shores, Screw Jacks, and Guardrail Systems.
