Custom sheet metal, not off-the-shelf — built around your exact requirements.
Every cabinet on this page was built for a specific project. Your dimensions, materials, protection grade, door layout and cable entries are all decided by you — we handle structure design, process planning, fabrication and testing. This page shows what we have done and what we can do for your project.

✅ High-precision Sheet Metal Processing
Adopt professional laser cutting, stamping, CNC bending and seamless welding technologies. Strict tolerance control ensures accurate hole positions, uniform assembly gaps and perfect fitting with original equipment. No burrs or deformation on the surface, meeting the high assembly standards of industrial and mining equipment.
✅ Rugged Structural Design
Built with thickened industrial-grade metal plates and reinforced frame structure, featuring excellent rigidity and impact resistance. Effectively resist vibration, impact and deformation during operation, transportation and on-site use.
✅ Harsh Environment Adaptability
The electrostatic powder coating provides superior scratch, UV and corrosion resistance, effectively protecting against dust, moisture and chemical erosion in mining and industrial environments. Various color options are available.
✅ Customized Solutions
Custom dimensions, opening layouts, internal brackets, surface colors and IP protection grades can be tailored according to customer drawings or samples. Our engineering team offers structural optimization suggestions to improve product practicability and durability.
