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/.

Floor-Standing Industrial Control Cabinet Shells: RFQ Guide

FLOOR-STANDING CABINET SHELLS

A floor-standing industrial control cabinet shell should be quoted from defined loads, datums, door geometry, plinth details, thermal interfaces and handling requirements. “Heavy duty” is not a specification, and a large cabinet should not inherit lifting or load claims that were never engineered.

Engineer inspecting the base plinth of a floor-standing control cabinet shell — Control the cabinet-to-plinth interface, anchor pattern, flatness and handling features from buyer-approved drawings.

Turn Cabinet Size Into Engineering Inputs

Question	RFQ input	Fabrication check
What carries the equipment?	Component mass, center of gravity, mounting pattern and service load	Backplate geometry, supports and attachment features
How is the cabinet installed?	Floor, skid or plinth interface; anchor pattern; leveling method	Base dimensions, hole pattern, flatness and access
What is mounted on the door?	HMI, controls, ducts, windows and cable loads	Cutouts, reinforcement, hinge and latch relationships
How is heat managed?	Buyer-selected vents, fans, exchangers or HVAC interfaces	Openings, fasteners, supports and service clearance
How is it moved?	Packing, forklift, pallet, skid or engineered lifting plan	Only the handling features shown in the approved scope

Control Frame, Plinth and Mounting Datums Together

Cabinet frames, bases and mounting plates accumulate tolerance across bends, welds and assembly. The drawing should identify functional datums, door openings, panel interchangeability, anchor locations and any surfaces that must align with adjacent equipment.

Formed uprights for a large industrial control cabinet frame — Formed sections and welded assemblies should be inspected from functional datums after the processes that can move them.

Mounting plate

Define installed load, edge returns, supports, hole pattern, removal path and flatness where components attach.

Plinth and base

Control footprint, anchor holes, cable entry, leveling, access panels and connection to the cabinet frame.

Doors

Record opening size, installed loads, hinge axis, latch locations, gasket land and required service angle.

Side and rear panels

Define removable panels, fasteners, alignment, bonding points and interfaces to neighboring equipment.

Door Fit Is a System, Not One Gap Dimension

A large door can change after welding, finishing and hardware installation. Control opening diagonals, hinge position, latch engagement, gap, flatness and any gasket relationship. If a protection target is specified, the complete seal path and installed penetrations need their own verification plan.

Inspector checking a multi-point latch on a control cabinet door — Check operation and engagement with the specified hardware installed and the cabinet supported in the intended orientation.

Thermal and Cable Interfaces Stay With the Buyer Design

Fans, filters, heat exchangers, air conditioners and cable systems should be selected by the responsible electrical or thermal designer. The sheet metal package should carry their exact cutouts, supports, keep-out zones, fasteners and service access. A generic opening can be expensive when the real component arrives two millimeters wider.

Engineering review of mounting and service interfaces inside a control cabinet shell — Review component clearances and mounting loads before releasing the empty-shell drawings.

Buyer Trust Table

Supplier statement	Evidence to request	Buyer value
“Heavy-duty frame”	Material, section geometry, weld notes and buyer-defined loads	Replaces an adjective with an approved design basis
“Lifting points included”	Approved load case, detail and responsible validation party	Avoids treating unverified hardware as a rated lifting system
“Door seals correctly”	Gap, flatness, hinge, latch and gasket checks	Makes the door system reviewable
“Ready for integration”	FAI for datums, cutouts, hardware and panel fit	Reduces assembly-floor modification

Floor-Standing Control Cabinet RFQ Checklist

STEP model and controlled fabrication drawings
Installed equipment loads and mounting locations
Frame, base, plinth and anchor interfaces
Mounting plate pattern and removal path
Door-mounted components and service angle
Thermal equipment and cable-entry interfaces
Material, thickness, weld and finish notes
Critical datums and FAI requirements
Handling and shipping orientation
Change-control and repeat-order rules

For finished mechanical inspection, use the control cabinet door and hardware fit-up checklist to define frame datums, gaps, hinge movement, latch engagement and gasket responsibility.

Frequently Asked Questions

Does MSTFAB supply a wired control cabinet?

No. Standard scope is the drawing-defined empty sheet metal cabinet and specified mechanical hardware. Wiring, controls, programming and system integration remain outside that scope.

Can the shell include a plinth and mounting plate?

Yes, when the geometry, material, interfaces and inspection requirements are included in the approved drawings and quotation.

Can a fabricator choose the cabinet load rating?

The responsible designer should provide the load cases and acceptance requirements. Fabrication evidence can then be produced against that approved basis.

Send the Loads, Datums and Installation Details

For smaller, machine-mounted controls, see the industrial automation enclosure RFQ guide. For a floor-standing project, send the full cabinet package for mechanical review.
