01 / What We Fabricate

The Rack Structure — The Backbone of a BESS

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.

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.

Module Shelves & Trays

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.

Rails & Slides

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 & Bracing

End plates, cross-bracing, and seismic anchoring provisions that keep the stacked rack stable and secure to the floor or structure where codes require.

Our scope: the sheet metal rack structure

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.

03 / Technical Capabilities

Load-Rated, Standard, and Ventilated

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.

04 / Manufacturing Process

From Steel to Battery Rack

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.

01

DFM & Load Review

Review your module dimensions, weight, and stack height — confirm material, post gauge, load rating, rail layout, and seismic requirements.

02

Laser Cutting

Fiber laser cutting of posts, shelves, rails, and end plates — with 19-inch mounting holes, ventilation openings, and anchoring points.

03

Forming

CNC press-brake forming — corner-folded posts and rails for strength, accurate bends so modules and rails fit to the 19-inch standard.

04

Welding & Assembly

Welding the frame for rigidity, installing rails/slides and shelves, and fitting hardware — building a rack that carries the full stacked load.

05

Finishing

Powder coat or galvanized finish — corrosion protection and a clean appearance suited to indoor storage, telecom, and cabinet/container environments.

06

Inspection

Dimensional inspection of rail spacing and mounting, load and fit verification, and finish inspection before delivery for your module integration.

05 / Why It Matters

What Makes a Battery Rack Perform

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.

Load Capacity

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.

Seismic Stability

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.

Thermal Airflow

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.

Standard Fit & Scalability

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.

09 / FAQ

Battery Module Rack FAQ

Do you build complete battery systems or just the rack?

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.

Do you support the 19-inch standard?

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.

How much load can the rack carry?

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.

Are the racks seismic-rated?

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.

How do heavy modules get installed?

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.

What's your minimum order quantity?

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.
