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/.

How to Buy an Empty Sheet Metal Electrical Cabinet Shell

OEM EMPTY ELECTRICAL CABINET SHELL SOURCING GUIDE

Answer: buy the empty cabinet shell from controlled drawings, not from a vague description such as “electrical cabinet.” Compare the same material, parts, hardware, finish, inspection and packing.

This electrical cabinet shell sourcing checklist covers the sheet metal enclosure MSTFAB actually manufactures. We supply cabinet bodies, doors, blank mounting plates, brackets, gland plates and specified mechanical hardware. We do not supply breakers, busbars, switchgear, wiring, electrical assembly, energization or a finished power-distribution cabinet.

MSTFAB empty floor standing sheet metal electrical cabinet shell with blank mounting plate and no electrical components — **Empty sheet metal electrical cabinet shell**Drawing-based metal shell for customer integration; no electrical components included.

What exactly should the buyer purchase?

Cabinet body

Shell, doors, panels, roof, base or plinth.

Interfaces

Blank plates, brackets, gland plates and cutouts.

Hardware

Hinges, latches, handles, studs and gaskets.

Evidence

Material, dimensions, finish and packing records.

MSTFAB can supply	Outside MSTFAB scope	Customer owns
Empty cabinet shell, doors, panels and base	Breakers, meters, switchgear and transformers	Electrical architecture and component selection
Blank mounting plates, brackets and gland plates	Busbars, terminals, wire ducts, cables and harnesses	Electrical clearances, layout and cable routing
Released cutouts, mechanical hardware, finish and packing	Wiring, energization, commissioning and system certification	Heat load, ingress target, safety and final validation

MSTFAB engineers reviewing empty electrical cabinet shell drawings material doors cutouts and mechanical interfaces — **RFQ and DFM review**Checks fabrication and inspection feasibility, not electrical-system design.

1. Send drawings that define the same quotation scope

Send a STEP assembly plus controlled 2D drawings. The model shows relationships; the drawings define material, thickness, datums, tolerances, welds, hardware, finish and inspection. A screenshot cannot control production.

STEP or STP assembly and part models
Controlled PDF drawings with revision
Material and thickness per fabricated part
Critical datums and realistic tolerances
Door gaps, cutouts and panel direction
Weld and hardware requirements
Finish, masking and cosmetic faces
Quantity, inspection records and destination

2. Lock material, thickness and mechanical loads

Cold-rolled steel, galvanized steel, stainless steel and aluminum change cost, forming, welding and corrosion strategy. The owner selects the material; MSTFAB verifies grade and thickness and does not substitute without approval.

“Make it strong” is not a load case

Provide approved mass, mounting, lifting and anchoring conditions.

3. Confirm the cabinet shell manufacturing route

The usual route combines laser cutting, CNC bending, hardware insertion, welding or assembly, finishing and inspection. Complete critical cutouts before coating.

MSTFAB press brake operator forming empty sheet metal electrical cabinet body door and side panels — **CNC bending**Radius, flange access and springback are reviewed before forming.

01. ReleaseFreeze drawings, BOM and material.

02. FabricateCut, bend, insert hardware and weld.

03. FinishPrepare, mask and apply the finish.

04. VerifyInspect dimensions, fit and packing.

4. Control doors, cutouts, finish and sealing interfaces

Door swing, hinges, latches and gasket geometry affect access and sealing. Device openings need controlled drawings and tool clearance. MSTFAB fabricates the interfaces; the customer validates the final assembly.

MSTFAB factory operator powder coating empty sheet metal electrical cabinet shells without installed components — **Powder coating**Define pretreatment, color, texture and masked functional zones.

Do not assume an IP or NEMA rating from the empty shell. Seals, penetrations, components and installation affect final validation.

5. Compare quotes using evidence, not only totals

Compare	Ask the supplier to state	Evidence
Fabricated scope	Every body panel, door, plate, bracket and hardware item	Quote line items and packing list
Material and process	Grade, thickness, joining and finish route	Drawing review and requested material records
Quality control	Critical checks, sampling and report format	First-article or agreed inspection record
Delivery condition	Installed or loose parts, labels and export protection	Approved packing method

6. Use a complete RFQ checklist

Describe the item as an empty mechanical enclosure
Use one drawing and BOM revision
List included panels, plates and hardware
Exclude electrical components and wiring
Define material, thickness and loads
Control cutouts and mounting interfaces
Specify finish and masking
Agree first-article evidence
Confirm packing and destination

Frequently asked questions

Does MSTFAB supply complete electrical cabinets?

No. MSTFAB supplies empty shells and mechanical parts; electrical components, wiring and commissioning are excluded.

Can MSTFAB make mounting plates and equipment cutouts?

Yes, from controlled drawings. MSTFAB reviews manufacturability but does not design the electrical layout.

Can the empty shell include an IP or NEMA guarantee?

No rating should be assumed from the shell alone. The finished-product owner defines and validates the complete assembly.

What should buyers compare between quotations?

Compare material, scope, hardware, finish, inspection, delivery condition and packing.

What files are needed for quotation?

Send the STEP assembly, controlled 2D drawings, BOM, material, finish, mechanical interfaces, quantity and destination.

Send the empty-cabinet drawing package

MSTFAB will review the cut, bend, weld, hardware, coating, inspection and packing route before production.
