What does MSTFAB manufacture?

MSTFAB is the international brand of Guangzhou Maisituo Sheet Metal Manufacturing Co., Ltd. It makes drawing-defined sheet metal parts and empty mechanical enclosure shells for OEM buyers, using laser cutting, CNC bending, welding and mechanical assembly. Surface treatments such as powder coating may be coordinated with external partners depending on the order.

Which materials does MSTFAB work with?

Common options include carbon steel, galvanized steel, stainless steel and aluminum. Grade, thickness, dimensions, critical tolerances, hardware, finish and inspection criteria are specified per project on the approved drawing.

What are the MOQ and lead time for custom sheet metal parts?

There is no single MOQ or lead time that applies to every part. MOQ, price, achievable tolerances, lead time, finishing route and inspection deliverables are confirmed in the project quotation and purchase order after the drawing is reviewed.

Does MSTFAB supply electrical components or certified finished equipment?

No. The normal supply scope is fabricated metalwork and empty mechanical housings. Electrical components, wiring, software, system integration and final equipment certification remain with the buyer unless a written quotation or contract explicitly includes them.

How do I request a quote?

Send STEP, STP, DXF, DWG or PDF files with the drawing revision, material and thickness, quantity, critical dimensions, hardware, finish, inspection needs and delivery destination through the RFQ page at https://mstfab.com/contact/.

Battery Storage Enclosure Mechanical Interface Checklist

EMPTY-SHELL MECHANICAL INTERFACES

A battery storage enclosure RFQ should define the mechanical interfaces that the empty shell must support: rack or tray datums, mounting loads, cable entries, airflow openings, removable panels, doors, base connection, grounding provisions and service access.

Empty sheet metal enclosure shell for battery storage equipment — Quote the shell around controlled mechanical interfaces; battery modules, controls and system safety remain part of the buyer’s completed design.

Build One Interface Control Package

Equipment mounting

Rack, tray, rail and bracket datums, loads, fasteners and installation access.

Thermal openings

Buyer-selected fan, filter, duct or heat-exchanger cutouts and service clearances.

Cable routing

Gland plates, entry zones, bend space, strain relief and separation requirements.

Cabinet structure

Base, lift, anchor, door, panel, shelf and transport restraint interfaces.

Engineering review of battery storage enclosure mechanical interfaces — Resolve mounting, cooling and cable conflicts before releasing flat patterns.

Separate Shell Fabrication From System Performance

The metal enclosure can be manufactured to the buyer’s geometry and mechanical requirements, but it does not independently establish thermal performance, electrical safety, fire performance or an environmental rating. Define who selects components, who validates the assembled system and which evidence the fabricator must provide.

Mechanical frame and mounting skeleton for an empty battery storage cabinet — The structural route should follow the buyer’s load cases, support condition and installation method.

Inspect From Functional Datums

Overall cabinet dimensions are not enough if rack holes, door openings, gland plates and cooling cutouts do not align. Mark critical-to-function characteristics and identify whether they are checked before coating, after coating or during trial assembly. Document approved deviations before the shell becomes the baseline for repeat orders.

Dimensional inspection of battery enclosure mounting and access interfaces — Measure the interfaces that control equipment fit, service access and installation.

Buyer Trust Table

Supplier statement	Evidence to request	Buyer value
“Battery cabinet ready”	Controlled empty-shell scope and interface matrix	Prevents missing system responsibilities
“Cooling supported”	Selected component drawings, openings and mounting checks	Confirms mechanical fit without claiming thermal validation
“Load capable”	Buyer load cases, structural review basis and inspection points	Ties strength to a defined condition
“Ready for production”	Approved first article, deviations and revision baseline	Controls the repeat order

Frequently Asked Questions

Does MSTFAB supply a complete battery energy storage system?

No. MSTFAB supplies drawing-defined empty enclosure shells and mechanical parts, not battery modules, controls or a certified energy storage system.

Can the enclosure supplier choose the cooling system?

The buyer or system engineer should define thermal requirements and select the cooling approach. MSTFAB can fabricate the approved mechanical interfaces.

What should the first article prove?

It should prove the drawing-defined fit, access, hardware, finish and critical interfaces that the buyer needs before repeat production.
