Who we are
A drawing-driven sheet metal manufacturing partner.
MSTFAB is the international brand of Guangzhou Maisituo Sheet Metal Manufacturing Co., Ltd., a 5,000 m2 custom sheet metal fabrication factory in Panyu, Guangzhou. For more than two decades, we have manufactured enclosures, cabinets, chassis, panels, brackets and welded assemblies for overseas OEM equipment teams.
Projects begin with the buyer’s controlled drawing. Our engineers review material, thickness, bend access, tolerance stack-up, weld sequence, hardware, finish and packing before release. That conversation is less glamorous than a laser-cutting video, but considerably cheaper than finding the problem after powder coating.
Prototype and repeat production are supported in carbon steel, galvanized steel, stainless steel and aluminum. We manufacture the mechanical parts in the approved scope; electrical components, wiring, software and final product certification remain buyer-controlled unless the purchase order clearly says otherwise.
Our capabilities
One accountable route for sheet metal parts.
The exact route follows the drawing, material and risk. These eight stages cover common work for finished mechanical parts and empty enclosure shells. Specified finishing may be completed by qualified long-term partners; MSTFAB coordinates the agreed scope and inspection.

Fiber laser cutting
Drawing-controlled flat patterns for panels, brackets, chassis and cabinet parts.

CNC turret punching
Repeat holes, ventilation patterns and formed features produced efficiently.

CNC press brake bending
Tooling, bend relief and access reviewed before formed parts reach assembly.

Precision TIG and MIG welding
Fixture-controlled joining for enclosure seams, frames and welded structures.

PEM hardware insertion
Studs, nuts and threaded hardware installed with position and access in mind.

Partner-coordinated finishing
Powder coating and other specified treatments can be arranged with qualified long-term partners. Color, masking and inspection requirements are agreed per order.

Dimensional inspection
Critical features checked against the released drawing and inspection scope.

Assembly and export packing
Fit checks and protection planned around surfaces, geometry and the shipping route.
These images illustrate manufacturing steps; they are not evidence of a particular order or proof that every process is in-house. Equipment, finishing location and inspection records follow the approved project scope.
Why choose MSTFAB
Practical controls, not decorative badges.
Overseas buyers need a supplier whose answers survive engineering, quality and procurement review. Our job is to make the build easier to understand before the first sheet is cut.
Managed workflow
Drawing release, process checks and shipment records follow a defined quality-managed production route.
Questions before cutting
Bend access, tolerances, weld distortion, hardware and finish allowances are reviewed before production.
Evidence before repetition
First-article checks can confirm the agreed critical features before a repeat batch moves forward.
Packing around risk
Protection is planned around cosmetic surfaces, cabinet geometry, loose parts and the shipping route.
Buyer check: ask which dimensions are critical, who owns each inspection step and what evidence will arrive before shipment. A clear answer is more useful than a very enthusiastic brochure.
Drawing to delivery
One accountable production workflow.
The exact control plan follows the drawing and project risk. These six stages keep engineering decisions connected to the finished part.
