Rack Frame & Posts
The structural frame — folded steel or aluminum posts (not flat strips, but corner-folded for strength) with 19-inch mounting rails, sized to carry the full stacked module load.
Custom battery module racks and BESS racks — 19-inch rack-mount frames, module stacking structures, shelves, and rails in steel and aluminum. Load-rated, seismic-aware, and ventilated. We build the sheet metal rack structure; you integrate the cells, modules, and BMS.
In a battery energy storage system, cells become modules, and modules stack into racks. We fabricate that rack — the load- bearing sheet metal structure that holds, organizes, and cools the modules you integrate.
The structural frame — folded steel or aluminum posts (not flat strips, but corner-folded for strength) with 19-inch mounting rails, sized to carry the full stacked module load.
Load-rated shelves and trays that support each battery module, with ventilation openings that let cooling air flow around the modules while keeping structural strength.
Mounting rails and slides so heavy modules slide into the rack along supported guides — then bolt in place — making installation and servicing manageable.
End plates, cross-bracing, and seismic anchoring provisions that keep the stacked rack stable and secure to the floor or structure where codes require.
We fabricate the rack structure — frame, posts, rails, shelves, trays, end plates, and bracing — laser-cut, formed, welded, and finished, ready for module integration. Bought-out components such as battery cells and modules, the BMS, busbars and cabling, thermal management, fire suppression, breakers and contactors, and the electrical system are integrated by you or your assembly partner. We build the rack with rails, shelves, and provisions sized to your modules.
We fabricate the rack structure for the full range of energy storage and backup applications, to your modules and design.
19-inch Standard 19-inch racks for rack-mount battery modules (3U and up) — the building block of scalable BESS, data center backup, and modular storage.
C&I Heavy-duty module stacking racks for commercial and industrial BESS — high load capacity, seismic-aware structure for cabinets and containerized systems.
Telecom Racks for telecom base-station backup — 48V/51.2V rack-mount lithium systems in compact, reliable structures for outside-plant and indoor sites.
Residential Compact stacking racks for residential solar storage — clean, space-saving structures for stackable home-battery modules and small hybrid systems.
A battery rack has to carry serious weight, fit standard modules, survive seismic events, and let the modules breathe. Here's what we fabricate to.
| Materials | Cold-rolled steel, galvanized steel; aluminum for lightweight racks |
|---|---|
| Post Construction | Post geometry, material and thickness released from the approved structural design |
| Standard | 19-inch (482.6 mm) mounting; EIA universal hole spacing for rack-mount modules |
| Load Rating | Engineered to your stacked module weight — heavy-duty racks rated to high loads |
| Module Support | Rails/slides for slide-in mounting, plus shelves/trays — bolted in place when seated |
| Seismic | Floor/structure anchoring provisions; seismic-zone-aware design (NEBS-class awareness) |
| Ventilation | Vented shelves and openings for cooling airflow around modules, retaining strength |
| Scalability | Modular — stack modules and gang racks to expand capacity at the same voltage |
| Finishing | Powder coat (RAL match), galvanized; data-center/storage colors common |
We fabricate the rack structure to your modules and load, with rails, shelves, and provisions sized to your design. Cells, modules, the BMS, busbars, thermal management, and fire suppression are integrated by you or your assembly partner.
A battery rack lives or dies on load capacity, fit, and stability. Our process delivers a rack that carries the load, fits the modules, and stays standing.
Review your module dimensions, weight, and stack height — confirm material, post gauge, load rating, rail layout, and seismic requirements.
Fiber laser cutting of posts, shelves, rails, and end plates — with 19-inch mounting holes, ventilation openings, and anchoring points.
CNC press-brake forming — corner-folded posts and rails for strength, accurate bends so modules and rails fit to the 19-inch standard.
Welding the frame for rigidity, installing rails/slides and shelves, and fitting hardware — building a rack that carries the full stacked load.
Powder coat or galvanized finish — corrosion protection and a clean appearance suited to indoor storage, telecom, and cabinet/container environments.
Dimensional inspection of rail spacing and mounting, load and fit verification, and finish inspection before delivery for your module integration.
The rack holds the energy — and the safety. Four things separate a rack that performs from one that fails under load or in a seismic event.
Stacked battery modules are heavy. The rack must carry the full load without sagging or failing — corner- folded posts and engineered shelves are what make it structurally sound.
In seismic zones, building codes require racks to be anchored and stable. Proper bracing and floor anchoring keep a heavy, tall battery stack from toppling — a safety essential.
Batteries need to stay cool for safety and life. Vented shelves and airflow openings let cooling air move around the modules — while keeping the structure strong.
The 19-inch standard and clean rail layout let modules install and service easily — and let the system scale by stacking modules and ganging racks as capacity needs grow.

Heavy brackets added mass, vibration loosened attachments and poor heat transfer increased module temperature.

From a first rack through high-volume production, with consistent fit and DFM feedback.
We fabricate the sheet metal rack structure — frame, posts, rails, shelves, trays, end plates, and bracing. The battery cells and modules, BMS, busbars and cabling, thermal management, fire suppression, and electrical system are integrated by you or your assembly partner. We build the rack with rails, shelves, and provisions sized to your modules.
Yes — we fabricate to the 19-inch (482.6 mm) standard with EIA universal hole spacing, so standard rack-mount battery modules (3U and up) install cleanly. We also build custom-width racks where your modules require it.
The responsible engineer defines the load cases, post geometry, shelf rating and acceptance method. Send the module weight, stack height and released structural requirements for an RFQ-specific fabrication review.
We design with seismic awareness — bracing and floor/structure anchoring provisions for code compliance in seismic zones, which building codes typically require for tall, heavy battery stacks. We can build to your specific seismic-zone requirements.
We fit rails and slides so heavy modules slide into the rack along supported guides, then bolt in place when seated — far easier and safer than lifting and aligning at all four corners simultaneously.
We support everything from a single rack to high-volume production. Send us your module specs and requirements and we'll confirm MOQ and pricing for your project.
