Rectangular Open-Frame Chassis Housing With Electronic Metal Chassis and Perforated Mounting Flanges

5052-H32 and 6061-T6 are the two alloy grades most specified for a rectangular open-frame electronic metal chassis with perforated mounting flanges; 5052-H32 provides superior formability for flanged chassis bends and better corrosion resistance in shipbuilding and oil & gas environments, while 6061-T6 is specified for aerospace and drone electronic metal chassis applications requiring higher flange stiffness and anodising adhesion. Perforated flange hole true position outside ±0.3 mm displaces the mounting screw centreline and requires the fastener to enter at an angle, generating thread galling and uneven PCB or sub-assembly mounting clamp load. Dongguan Dalingshan Wangtuo Hardware Products Factory (Dongguan, Guangdong, ISO 9001 certified)(operating as Welltop)fabricates this rectangular open-frame electronic metal chassis with perforated mounting flanges at their north of 4,000 m² Dongguan facility, with flange hole true position, chassis face squareness, and panel thickness validated to your specification requirements during first-piece verification. Include hole true position, chassis squareness, panel thickness, and alloy grade in your RFQ package.
