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/.
