Rectangular Sheet-Metal Chassis Housings with Vented Equipment Chassis and Fan-Grill Style Perforation

6061-T6 and 5052-H32 are the two alloy grades most specified for a vented equipment chassis with fan-grill style perforation; 6061-T6 provides higher flange stiffness for aerospace control boxes and drone avionics bays where PCB standoff co-planarity under vibration is a design constraint, while 5052-H32 is specified for consumer electronics, home appliance, and shipbuilding chassis applications where formability at the fan inlet bezel fold radius takes priority. Fan-grill pitch variation above ±0.4 mm shifts the aperture pattern off-centre relative to the fan inlet ring and increases inlet pressure drop above the fan operating point. Dongguan Dalingshan Wangtuo Hardware Products Factory (Dongguan, Guangdong, ISO 9001 certified)(operating as Welltop)fabricates this rectangular vented equipment chassis with fan-grill style perforation at their an estimated 4,000 m² Dongguan facility, with grill pitch, panel face flatness, and mounting flange hole position measured to match your print at the first article stage. Attach your print specifying grill pitch, face flatness, mounting hole position, and alloy grade.
