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/.

Telecommunications Enclosure RFQ Checklist for Outdoor Networks

CUSTOM ENCLOSURE FABRICATION

A good telecom enclosure is not just a metal box. It must protect communication uptime by controlling heat, rain, dust, condensation, corrosion, cable routing, grounding and field maintenance access. MSTFAB manufactures custom empty sheet metal cabinet shells built to your project’s environmental realities.

Design Priorities for Telecom Cabinets

Telecom cabinets usually fail in the field because the drawing did not fully describe the environment. For better RFQ accuracy, define the expected equipment heat load, cable direction, louver strategy, grounding path, and corrosion exposure before production starts.

Thermal Management

Airflow direction, fan cutouts, filter slots, heat source spacing, and stamped louvers must be planned early.

Weather Protection

Gasket channels, door flatness, rain hoods, and pressure equalization ensure long-term IP/NEMA integrity.

Field Service

Door swing clearance, removable panels, rack rail depth, and cable bend radius simplify maintenance.

Outdoor Durability

Material grade, pretreatment, outdoor powder coating, and masked grounding points protect against corrosion.

Manufacturing Route for Custom Enclosures

Our fabrication process integrates DFM review, precise laser cutting, controlled CNC bending, and strict quality inspection to ensure the empty cabinet perfectly accommodates your network equipment.

1. DFM ReviewReview 3D CAD files for bend limits, gasket channels, and thermal layout.

2. Laser CuttingCut louvers, fan holes, cable glands, and rack slots with clean edges.

3. CNC BendingHold door flatness and sealing lips so the telecom enclosure closes correctly.

4. Hardware FitTrial-fit hinges, locks, rack rails, and PEM fasteners before powder coating.

Critical Quality Control Gates

We check IP sealing intent, powder coating coverage, dimensions, grounding continuity, and visible surfaces before export packaging.

Door Flatness & Bending

Frame squareness and precise CNC bending protect long-term sealing and field service reliability.

IP Sealing Inspection

Quality control checks ensure gasket channels and door alignment meet the intended IP/NEMA protection level.

Grounding & Cable Entry

Masked grounding studs, removable gland plates, and smooth cable routing access must be flawless.

Surface Finish QC

Outdoor-grade powder coating, deburring, and edge coverage decide how long the cabinet resists corrosion.

Material Choices for Telecom Enclosures

Option	Best Use	Buyer Check
Powder coated steel	Cost-effective outdoor telecom cabinets and network equipment housings.	Specify pretreatment, coating thickness, and UV resistance.
Galvanized steel	Better base corrosion resistance for semi-protected telecom cabinets.	Confirm cut-edge protection and weld repair method.
Aluminum	Lightweight outdoor network enclosures and transport-sensitive cabinets.	Check thickness, grounding design, and galvanic corrosion risk.
Stainless steel	Coastal, humid, chemical, or high-corrosion installation environments.	Confirm grade (304/316) and passivation requirement.

Frequently asked questions

What is a telecommunications enclosure?

It is a sheet metal cabinet or housing used to protect routers, switches, fiber optic systems, power modules, batteries and communication devices in outdoor or industrial environments.

Does MSTFAB make finished telecom equipment?

No. MSTFAB mainly manufactures custom empty sheet metal telecom enclosure shells and assemblies from buyer drawings. Electronics, wiring, network equipment and final field certification are buyer-defined.

What files are needed for quotation?

Send STEP files, 2D PDF drawings, material, thickness, finish, quantity, IP/NEMA target, cable-entry layout, rack rail requirements, grounding points, hardware details and packing requirements.

Can MSTFAB support outdoor IP65 or NEMA-style cabinets?

Yes. MSTFAB can fabricate cabinet structures with gasket channels, louvers, rain hoods, locks, hinges, grounding studs, powder coating and export packing according to buyer drawings and project requirements.

Need Custom Telecommunications Enclosures?
