Advantages: 

Strict welding standard: Firm, aesthetic weld seams; sheet metal & square tubes welded at perfect vertical angles, zero misalignment.

Full post-weld finishing: Complete weld slag removal, thorough grinding for smooth, flawless surfaces; all burrs, flash edges on holes and panels fully eliminated.

Sharp edge deburring & blunting: All sharp corners and sharp edges rounded off to avoid scratches and safety hazards.

Deformation control system: Stress relief annealing + flat straightening processes to minimize post-processing distortion, ensure flatness meets strict tolerance standards.

Dual fastening solution: Bolts & nuts fully tightened then spot-welded for ultra-reliable, long-lasting connection.

Complete pre-assembly inspection: Every finished cabinet undergoes trial fitting with brackets and covers, all bolts fit smoothly without assembly interference.

Quality control system

Every production step is inspected from raw material forming, welding, surface finishing to pre-assembly testing, with all dimensional, appearance, electrical and corrosion indicators strictly aligned with international technical standards, delivering stable, durable and high-standard custom metal & busbar solutions.
