Du Manutenções Elétricas is a residential and commercial electrical maintenance company based in Paraná, Brazil, focused on reliable, high-quality technical work. The visual identity, developed by Oleodemarchi.design, translates that focus into a contemporary system built around clarity and control.
The logo combines stylized “D” and “U” letterforms using rounded rectangular geometry, suggesting structure, direction, and electrical flow through a subtle lightning reference.
A restrained palette of vibrantgreen, dark teal, and off-white reinforces energy and safety, while consistent use across signage, stationery, and branded materials creates a cohesive identity grounded in trust and technical confidence.
Leonardo Demarchi is a Brazilian designer and founder of oleodemarchi.design, with over eight years of experience in branding and visual identity. His work emphasizes strategic clarity, modern aesthetics, and functional design systems that help brands stand out and communicate with purpose.
