Many outdoor fitness equipment used to rely on solvent-based coatings

After installation people could still smell a strong and irritating odor

That is why more manufacturers have shifted to electrostatic powder coating

It offers lower VOC content less odor and better compliance with current environmental standards

But here is the real question

If powder coating is so good why do some gym equipment still fade or rust

First issue: poor adhesion and weak aging resistance

Powder used for outdoor fitness equipment should have strong adhesion good toughness and maintain years without chalking

But some manufacturers choose low-grade powder to reduce cost

These coatings are brittle and age quickly

In three to six months you may see chalking fading or loss of gloss

It looks like the equipment is not durable but the real reason is the coating quality

Second issue: coating grade does not match the corrosion environment

Outdoor environments vary from C3 C4 C5 to CX

The heavier the environment the higher the requirement for the coating

If low-level systems are used in coastal or highly corrosive areas

the coating will easily blister peel whiten or chalk

The wrong protection level makes it difficult for any coating to perform

The Mengneng powder coating system covers environments from C3 to CX

From inland urban areas to outdoor exposure zones and coastal regions

It can maintain more than 20 years without rusting with certification available

Third issue: details in the coating process

Unclean substrate surface dust in the coating room

or inconsistent application techniques

All of these can cause orange peel bubbles undercutting or particles

These problems require strict process control not simply blaming the coating itself
