Custom Sheet‑Metal Fabrication for Outdoor Power Box & Energy‑Storage Distribution Cabinet Enclosure

We fabricate heavy‑duty sheet‑metal enclosures for outdoor power distribution and energy‑storage systems. Featuring IP54‑IP65 waterproof & dust‑proof performance, reinforced anti‑deformation structure and anti‑salt‑spray surface finishing.

We deliver free 2D/3D CAD design according to your requirements, no drawing files from buyers needed, solving common pain points like cabinet water‑leakage, structural sagging and assembly mismatch for harsh outdoor working conditions.

Core Strengths & Pain Points We Solve

Most overseas purchasers struggle with: expensive third‑party drafting, cabinet water‑leakage in coastal/rainy sites, cabinet sagging caused by heavy battery load, bad hole‑position matching leading to poor assembly.

Free CAD & DFM design service — no drawings required from you Only share dimension, installation way, IP grade and functional demands. Our structural engineers produce production‑ready 2D/3D drawings with unlimited free revisions, cutting your pre‑development cost.

Optimized outdoor weather‑resistant construction Adopt integrated rain‑eave + double EPDM sealing groove, achieve stable IP54 / IP65 rating. Built‑in reinforcing ribs prevent cabinet deformation under heavy battery module weight, eliminate sagging & welding‑joint crack risks.

Precision in‑house sheet‑metal fabrication Full workflow: laser cutting, CNC bending, full‑penetration welding, anti‑corrosion powder‑coating. Tolerance ±0.1mm, guarantee precise hole location and seamless assembly. Support wall‑mount / floor‑standing / pole‑mount installation styles.

Flexible material & surface options SPCC cold‑rolled steel, galvanized steel, SS304 / SS316 stainless steel available. Weather‑resistant powder‑coat, galvanizing, stainless‑steel polishing for anti‑salt‑spray in coastal environment.

Application Industry & Scenarios

  • Solar PV project: PV combiner boxes for rooftop & ground‑mount solar stations
  • Energy‑storage industry: Commercial & residential ESS / BESS battery housing
  • Municipal power engineering: Street‑light control, community power distribution cabinets
  • Industrial automation: Outdoor equipment power control enclosure
  • Harsh environment projects: Coastal salt‑fog area, high‑humidity & dusty field sites

Spec Overview

  • Protection Grade: IP54 / IP65 customizable
  • Tolerance: ±0.1mm
  • Material: SPCC / SGCC / SS304 / SS316 / Aluminum alloy
  • Surface Finish: Powder coating, galvanizing, polishing
