QPQ coating is highly regarded for barbells due to its excellent corrosion resistance, wear durability, surface hardness, and low friction, making it one of the top choices, especially for serious lifting environments. However, whether it’s the “best” coating depends on specific needs and conditions. Here’s how QPQ compares to other popular coatings:
CORROSION RESISTANCE
QPQ excels in rust resistance, making it well-suited for humid or high-sweat environments. In terms of corrosion protection, it often rivals or even surpasses hard chrome and black oxide.
DURABILITY AND WEAR RESISTANCE
The QPQ process creates a hard, wear-resistant surface that guards against scratches and scuffs, providing durability for frequent, intense use. Hard chrome also offers similar scratch and wear resistance but can chip if applied too thickly, whereas QPQ has a smooth, seamless finish.
GRIP AND TEXTURE
QPQ has a smooth, low-friction surface, allowing for a natural feel while still providing good grip. Some lifters prefer this smoothness over the slightly more slippery feel of hard chrome or the rougher feel of black oxide.
AESTHETIC APPEAL
QPQ has a distinctive matte black finish, giving it a sleek, professional look that resists fingerprints and smudging, unlike the shinier finish of hard chrome.
SUMMARY
For barbells in humid or high-use environments, QPQ is one of the best coatings due to its combination of durability, rust resistance, low friction, and appearance. However, stainless steel is another top contender, as it naturally resists rust without coating, although it can be pricier.
In conclusion, QPQ is among the best choices for high-quality barbells, especially for those prioritizing durability and a modern look.
