Long Description
We provide custom sheet metal electrical box and junction box welding fabrication service, focusing on outdoor and industrial circuit protection scenarios. Adopting cold-rolled carbon steel, stainless steel and galvanized sheet materials, we produce sealed, durable and safe electrical junction boxes through precision cutting and firm welding.
Products adopt fully sealed welding design, with optional waterproof rubber strips, rain cover and lock structure, effectively preventing rain, dust and moisture from entering, protecting internal circuits and electrical components from damage. We can precisely process wire holes, mounting holes and wiring slots according to customer drawings, ensuring convenient installation and stable operation of electrical components.
Surface adopts anti-corrosion spraying, galvanizing and passivation treatment, with strong weather resistance, suitable for outdoor, underground and industrial workshop harsh environments. We support small-batch customization and mass production, with complete specifications and flexible design, providing reliable circuit protection solutions for engineering and electrical industries.
