Standard requirements for thickness of integrated distribution boxes

The steel plate thickness for distribution boxes typically ranges from 1.5 mm to 2.0 mm, depending on the box size and type, with anti-corrosion treatment required.Material and Thickness Standards

Distribution boxes are generally made from cold-rolled steel plates or flame-retardant insulating materials. According to JGJ46-2005, the minimum thickness for distribution box steel plates is 1.5 mm, while switch boxes require at least 1.2 mm. The surface must be treated to prevent corrosion, ensuring durability and safety in electrical installations . For larger boxes, practical specifications recommend:

  • Long side < 1000 mm: plate thickness ≥ 1.5 mm
  • Long side ≥ 1000 mm: plate thickness ≥ 2.0 mm If the box plate is thinner than 3 mm, additional reinforcement using galvanized flat steel or angle steel may be required to maintain structural integrity during installation .
Reinforcement and Installation Considerations
  • Thin plates (3 mm): Weld a 3 mm galvanized flat steel at the upper and lower ends of the back, with L-shaped angle steel at midpoints for mounting support . These measures ensure the box can safely support internal components such as MCBs, RCDs, busbars, and terminal boards without deformation.
Summary
  • Material: Cold-rolled steel or flame-retardant insulating material
  • Minimum thickness: 1.5 mm for distribution boxes, 1.2 mm for switch boxes
  • Larger boxes: ≥ 2.0 mm for long sides ≥ 1000 mm
  • Surface treatment: Anti-corrosion coating
  • Reinforcement: Required for plates thinner than 3 mm to maintain rigidity and safe installation These standards ensure that integrated distribution boxes meet both structural and electrical safety requirements while accommodating internal components and installation needs.
