Precision-engineered network & server equipment enclosures built to your exact specifications
From initial concept to final delivery –every detail of this custom fabrication project
Driven by the build-out of 5G, cloud and big-data infrastructure, a leading global network equipment manufacturer launched a 2026 program for 1,200 sheet metal cabinets covering server, switch and wall-mounted network use. The enclosures had to carry heavy servers and switches while staying compact enough for standard racks.
The customer’s previous supplier struggled to balance heavy load, EMC shielding and batch consistency. Cabinets were either too heavy and costly, or lost shielding strength when ventilation holes were added. Moist server rooms also caused early corrosion.
Three engineering tensions defined the project: load versus lightweight, cooling versus shielding, and large-batch consistency. Finite element analysis guided rib placement, while a dual-layer rear door kept holes small enough to preserve shielding.
SanJun selected 1.5mm SPCC for the frame and 1.2mm for panels, added integrated CNC-formed reinforcing ribs and welded angle irons at stress points. A dual-layer rear door with Φ3mm holes, conductive foam gaskets and welded grounding bolts formed a continuous shielding loop.
The 1,200 sets shipped four days ahead of the 35-day schedule with a 100% pass rate across load, EMC, IP and precision tests. After ten months in 15+ data centers and 300+ rooms, there were zero reports of deformation, corrosion or interference.
SanJun’s professional grasp of network cabinet requirements and rigorous batch-customization capability made them the obvious long-term partner.
