We build energy storage cabinets from your drawings at our factory in Huizhou, China.<\/p>\n<h2>What we fabricate for energy storage<\/h2>\n<ul>\n<li>Battery cabinets and storage containers (sheet metal enclosure + frame)<\/li>\n<li>Load-bearing welded frames in square tube and sheet<\/li>\n<li>Module shelves, dividers and mounting plates<\/li>\n<li>Removable service doors and access panels<\/li>\n<li>PCS \/ inverter housings and control cabinets<\/li>\n<li>Cable entry plates and ventilation covers<\/li>\n<\/ul>\n<p>Related parts: <a href=\"https:\/\/www.eoil.com\/index.php\/en\/product\/equipment-base-en\/\">equipment base<\/a>, <a href=\"https:\/\/www.eoil.com\/index.php\/en\/product\/cabinet-frame-en\/\">structural frame<\/a>, <a href=\"https:\/\/www.eoil.com\/index.php\/en\/product\/equipment-housing-en\/\">equipment housing<\/a>, <a href=\"https:\/\/www.eoil.com\/index.php\/en\/product\/powder-coated-part-en\/\">powder-coated parts<\/a>.<\/p>\n<h2>Where storage cabinets fail<\/h2>\n<ul>\n<li><strong>Sagging shelves.<\/strong> Modules are heavy and concentrated. A flat 2&nbsp;mm shelf with no stiffening will bow. We add formed ribs or folded edges sized to the actual load, and check flatness after welding.<\/li>\n<li><strong>Coating that does not last.<\/strong> Outdoor installations mean UV, rain and temperature cycling. We use outdoor-grade powder over a full degrease\u2013descale\u2013phosphate pre-treatment, and check adhesion by cross-cut and film thickness.<\/li>\n<li><strong>Distortion after welding.<\/strong> A welded frame pulls as it cools. We weld in a jig, control the sequence and heat input, then straighten and verify diagonals on a CMM.<\/li>\n<li><strong>Serviceability.<\/strong> Technicians need to reach the modules. Door geometry, hinge positions and cable routing are worth reviewing at the drawing stage rather than on site.<\/li>\n<\/ul>\n<h2>Specifications<\/h2>\n<table>\n<tbody>\n<tr>\n<td><strong>Frame<\/strong><\/td>\n<td>Welded square tube and sheet steel, straightened after welding<\/td>\n<\/tr>\n<tr>\n<td><strong>Panels<\/strong><\/td>\n<td>Galvanized SGCC 1.5\u20133.0&nbsp;mm, cold-rolled SPCC, stainless 304<\/td>\n<\/tr>\n<tr>\n<td><strong>Cutting<\/strong><\/td>\n<td>Fiber laser, 3000 \u00d7 1500&nbsp;mm, \u00b10.05&nbsp;mm<\/td>\n<\/tr>\n<tr>\n<td><strong>Forming<\/strong><\/td>\n<td>CNC press brake up to 3200&nbsp;mm, angle tolerance \u00b10.5\u00b0<\/td>\n<\/tr>\n<tr>\n<td><strong>Welding<\/strong><\/td>\n<td>MIG\/CO<sub>2<\/sub> and TIG, jig-controlled, ground flush where visible<\/td>\n<\/tr>\n<tr>\n<td><strong>Coating<\/strong><\/td>\n<td>Outdoor-grade electrostatic powder, RAL colours, 60\u201380&nbsp;\u00b5m<\/td>\n<\/tr>\n<tr>\n<td><strong>Load<\/strong><\/td>\n<td>Shelf loading tested to your specification<\/td>\n<\/tr>\n<tr>\n<td><strong>Order size<\/strong><\/td>\n<td>From 1 prototype cabinet to full production runs<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Quality control and documentation<\/h2>\n<p>Incoming material, first article, in-process and outgoing inspection. Frame diagonals and shelf flatness are measured on a CMM; coating adhesion and film thickness are sampled. Inspection records are kept per batch so a delivery can be traced back to its material lot.<\/p>\n<h2>Working with your engineering team<\/h2>\n<p>Energy storage designs change fast \u2014 cell formats change, module sizes change, and the cabinet has to follow. Because everything is built from drawings, a revision is a new drawing set rather than a new tooling investment. Send us the revision and we re-quote only what actually changed.<\/p>\n<h2>Frequently asked questions<\/h2>\n<h3>Can you supply the cabinet only, without electrical assembly?<\/h3>\n<p>Yes. Many customers take the sheet metal and frame only and assemble the electrical side themselves. We can also supply partially assembled cabinets if that helps.<\/p>\n<h3>How do you handle export packing for large cabinets?<\/h3>\n<p>We pack to container dimensions with corner protection and moisture control. For bulky frames we can design knock-down versions that ship flat.<\/p>\n<h3>Do you offer prototypes before committing to volume?<\/h3>\n<p>Yes, and we recommend it. A single unit validates the fit, the coating colour and the assembly sequence before you commit to tooling or volume pricing.<\/p>\n<h2>Get a quotation<\/h2>\n<p>Send your drawings \u2014 DXF, STEP, PDF or a sample \u2014 with material, thickness, quantity and coating requirements.
