NET Electrodeposition Innovation
Key Technical Features
Eco-friendly Surface Treatment
Surface roughness enhanced through anodic electro-etching in harmless baking soda (sodium bicarbonate).
Improved Coating Adhesion
Enhanced surface roughness ensures superior coating adhesion.
High-Strength Electrodeposition Coating
Environmentally friendly, minimal material loss, superior moisture resistance, corrosion resistance, and abrasion resistance. Compared to conventional products, offers improved coating performance, cost reduction, and extended durability.
Conventional Method(Post-Assembly Coating)
After assembly, epoxy or urethane is manually applied, resulting in uneven coating on complex shapes such as welds and cut surfaces.
Frequent repairs needed due to cracks and peeling occurring within a few years.
Wonder Arch : Pre-Coated Assembly
Uses the NET-certified process to coat each panel individually before assembly.
Creates a uniform and durable coating across all surfaces and gaps.
Completely prevents cracks and peeling, ensuring semi-permanent durability.
