Expert Tips on How to Prepare Metal for Powder Coating

Yes – we do both. Your application (indoor vs. outdoor) is one of the first things we look at when recommending a coating system. • Indoor parts usually need good appearance and durability, but not extreme UV or weather resistance. Common examples: racks, fixtures, office furniture, indoor equipment, brackets, and machine guards. • Outdoor parts need higher protection from UV, moisture, temperature swings, and corrosion – think railings, fences, outdoor machinery, vehicles, trailers, architectural components, and signage. We’ll ask where and how your part will be used, then recommend: • The right pretreatment (for corrosion resistance) • The right powder chemistry (polyester, epoxy, hybrid, etc.) • Whether you need a primer + top coat system for extra protection If you’re not sure, just tell us where the part lives (inside a warehouse, outside in Utah weather, near chemicals, etc.), and we’ll guide you to the safest, most cost-effective option.

The “best” pretreatment depends on the material, the environment, and how long you need the finish to last. In general, good powder coating always starts with three steps: 1. Cleaning & degreasing • Removes oils, cutting fluids, fingerprints, and shop contaminants. • If this step is skipped or rushed, even the best powder will fail early. 2. Surface prep (mechanical or chemical) • Blasting (for steel, some aluminum) to create a profile for the powder to grip. • Or chemical etching / conversion coatings to improve adhesion. 3. Conversion coating / pretreatment • For steel, this might be iron or zinc phosphate. • For aluminum, it’s often a chromate-free conversion coating. • This adds corrosion resistance and helps the coating bond to the metal. For harsh environments (outdoor, coastal, chemicals, road salt), a more robust pretreatment system is recommended, sometimes combined with a primer layer under the powder. You don’t have to know what system you need – if you tell us: • What the part is made of (steel, aluminum, etc.) • Where it will be used • Any special requirements (food-grade, medical, high-temperature, etc.) …we’ll recommend the pretreatment and coating system that balances performance, durability, and cost.

We stock a range of popular standard colors that cover most industrial and commercial needs, and we can also source hundreds of additional colors and finishes from our powder suppliers. Options include: • Standard colors: black, white, gray, safety yellow, reds, blues, and other common RAL-style colors • Sheens: matte, satin, semi-gloss, full gloss • Specialty finishes: textures, hammertones, metallics, veins, and more (availability may depend on quantity) • Brand / custom colors: in many cases we can match or closely approximate a brand color if you provide a reference (RAL, Pantone, or a physical sample) Custom colors may require: • A minimum order quantity • A slightly longer lead time • Sometimes an additional color-match or setup charge If you already have a color in mind, send us: • A color code (RAL, Pantone if available), or • A clear photo + a short description (e.g., “matte dark charcoal,” “bright safety orange”) We’ll let you know what’s available off the shelf and what would be considered a special order.

Different powder chemistries are better suited for different environments. A few common types: • Polyester: • Great all-around choice for most outdoor and indoor applications • Very good UV and weather resistance • Commonly used on architectural components, outdoor equipment, railings, and furniture • Epoxy: • Excellent chemical and corrosion resistance, great for indoor use • Not ideal for UV exposure – it can chalk or fade outside • Often used for indoor machinery, racks, fixtures, and parts in more aggressive chemical environments • Hybrid (epoxy-polyester): • Good interior option with a balance of appearance and durability • Frequently used for indoor office furniture, panels, and general industrial parts • Specialty powders: • High-temp powders for parts exposed to elevated temperatures • Antimicrobial or ESD (electrostatic dissipative) coatings for specific industries • Clear coats to add extra protection and depth to metallics or graphics underneath When we quote your project, we look at: • Indoor vs. outdoor use • Exposure (UV, chemicals, moisture, temperature, cleaning agents) • Aesthetic expectations (high-gloss, matte, textured, ultra-smooth) From there, we recommend the top coat that gives you enough protection without over-engineering the job, so you’re not paying for performance you don’t actually need.

Lead time depends on: • The size of the order (number of parts, complexity) • Current production schedule • Whether we are using a stock color or ordering a special color • Any extra steps like masking, plugging, blasting, or multi-coat systems As a general guideline: • Small runs / simple jobs / stock colors: often a few business days to about a week once parts are in our shop and approved for production. • Larger runs, complex masking, or custom colors: typically 1–2+ weeks, depending on volume and material flow. • Rush jobs: If you’re on a tight deadline, let us know. When possible, we’ll work with you to prioritize your order or propose options (e.g., choosing an in-stock color to save time). We’re happy to review your drawings, photos, or part list and give you a more precise estimated turnaround based on your project and schedule.

Yes — we offer media blasting as part of our surface-preparation process when needed. Blasting is often the best way to give the powder coating a strong anchor profile and ensure long-term adhesion and durability. Blasting is especially recommended for: • Rusty or previously painted parts • Raw steel that needs a uniform profile before coating • Weldments with scale or heat discoloration • Heavily handled parts with oils, dirt, or oxidation • Outdoor-use parts that need maximum corrosion protection What blasting does: • Removes rust, mill scale, old paint, and contaminants • Creates a clean, roughened surface that powder can grip • Improves overall coating consistency and lifespan For aluminum, stainless, or delicate parts, we evaluate whether blasting is the best option or if a chemical pretreatment or lighter abrasion process is safer. If you’re unsure whether your parts need blasting, send us a photo or drop them off. We’ll assess the condition and recommend the most cost-effective preparation to get the best finish.

Yes — we work with both one-off projects and high-volume production, and we adjust our workflow to meet your needs. We support: • Single parts or prototypes • Small batches for repair, restoration, or custom builds • Mid-sized orders for local businesses and manufacturers • Large production runs with consistent, repeatable results For prototypes or one-off projects: • We can help you choose the right color and finish • We offer guidance on masking, tolerances, and design considerations • We often turn these jobs around quickly, especially when using in-stock powders For production work: • We offer consistent quality, repeatability, and predictable lead times • We can stock or reorder specific powders for color consistency • We can create a process plan that fits your production cycle • We work with companies across Utah and the U.S. who need a reliable finishing partner If you’re not sure where your order falls, just tell us the quantity and part details — we’ll guide you through the best approach.
