Professional manufacturer of metal fiber optic distribution boxes. Custom outdoor fiber junction boxes, wall-mounted fiber splice boxes for telecom FTTH projects, precision sheet metal OEM & ODM service.
We are a full-process precision sheet metal manufacturer specializing in tailor-made indoor & outdoor electrical cabinets, waterproof dustproof junction boxes and metal chassis housings with laser cutting and punching processing. We have overcome widespread industry troubles: thin plate bending springback deformation, inconsistent hole position precision in mass punching, poor sealing matching leading to water/dust ingress, welding thermal distortion and uneven coating defects on cabinet surfaces. Equipped with automatic laser cutting, CNC punching, CNC bending, precision welding and complete surface treatment workshops, we strictly control dimensional tolerance and IP sealing performance. We provide one-stop OEM & ODM customization for electrical distributors, automation system suppliers, engineering contractors and equipment manufacturers worldwide, delivering stable mass production, tight lead time and cost-optimized structural solutions.
As a professional sheet metal fabrication factory, we produce high-quality recessed multimedia low voltage distribution boxes available for bulk wholesale. Our enclosure adopts upgraded thickened SPCC steel panel structure with precise stamping ventilation holes for effective dust prevention. Electrostatic spraying surface treatment delivers outstanding anti-corrosion and anti-rust performance for long-term wall embedded installation. We support standard-size bulk supply and full OEM & ODM customization with tight ±0.1mm dimensional tolerance, consistent batch quality and reliable on-time delivery for global electrical distributors and construction engineering contractors.
We supply heavy-duty multimedia weak current boxes supporting both surface mount and flush mount installation, perfectly designed for FTTH fiber entry, network wiring and indoor low-voltage power distribution. As a professional sheet metal manufacturer, we support full-size non-standard customization, strict ±0.1mm machining tolerance, thickened cold-rolled steel body and anti-rust electrostatic spraying. Stable batch quality, flexible MOQ and on-time bulk delivery help you win more residential and commercial construction project orders easily.
