At Sinorides, painting is not just for looks—it’s key for quality, safety, and lasting durability.
Steel structures are the backbone of our rides, so protecting them from rust is crucial.
That’s why we follow a strict process—from shot blasting to a full 3-layer coating—to make sure every ride lasts long.
Pre-Coating Treatment: Shot Blasting Rust Removal
To make sure paint sticks well, all steel parts go through automated shot blasting before coating.
This process uses high-speed steel shots to remove rust and dirt, making the surface clean to SA2.5 or better, meeting global standards.
Benefits of Shot Blasting:
- Improves coating adhesion
- Removes oxide layers and impurities
- Ensures even surface roughness
- Extends coating lifespan
3-Layer Coating System for Maximum Protection
After shot blasting, we use a 3-layer system—primer, middle coat, and topcoat.
Each step follows global quality rules.
1. Epoxy Primer
- Purpose: Improves adhesion and prevents rust
- Key Points:
- The surface must be clean and dust-free
- Two coats applied; 4–6 hours between coats in summer, 24 hours in winter
- Film thickness: 60–80μm
2. Intermediate Coat
- Purpose: Enhances protection and adhesion between layers
- Key Points:
- One coat applied, thickness: 100–140μm
- The surface must be free of impurities
3. Topcoat
- Purpose: Provides color, gloss, abrasion, and weather resistance
- Key Points:
- The intermediate coat is sanded with 240-grit sandpaper after drying
- Two coats applied; 4–6 hours between coats in summer, 24 hours in winter
- Total thickness: 200–250μm
Why Do We Require ≥200μm Coating Thickness?
- Corrosion Resistance: Thick coatings protect better in humid, salty, or polluted environments.
- Longer Service Life: Thicker layers are more wear-resistant and have lower maintenance costs.
- International Standards: Meets ISO 12944 C5-M standard for ≥200μm. We ensure 200–250μm to meet global demands.
