01 / Core Process
▤
Steel Plate Milling
Milling for machined plates, mold bases, equipment bases, fixture plates and large frame plates.
Large-Format Steel Plate Machining
Steel Plate Machining
For Industrial Equipment
We mill, cut, surface-grind and flatten steel plates, with drilling, tapping, chamfering and welding available. Our large gantry machines handle plates up to approximately 2.5 m × 5 m. We assess standard industrial tolerances and lead times against your drawings.

Services
Machining Services for Large Steel Plates
From milling, cutting, grinding and flattening to holes, chamfers and welding, we make plate components to your drawings.
02 / Surface Processing
◫
Surface Grinding & Flattening
Flatness and dimensions are checked against drawings for industrial equipment and mold applications.
03 / Supporting Processes
⌁
Cutting & Secondary Operations
Cutting, drilling, tapping, chamfering and welding are available to produce the required plate geometry.
Machinable Materials
Common Industrial Steel Grades
We accept customer-supplied material and assess grades specified on drawings under ASTM, SAE/AISI, EN, DIN, ISO or local standards.
Carbon & Structural Steel
For equipment bases, large frame plates, construction machinery, welded structures and general industrial equipment.
ASTM A36ASTM A572 Gr.50EN S235 seriesEN S275 seriesEN S355 series
Medium-Carbon & Alloy Steel
For machine components, equipment plates, fixtures and industrial parts with specified strength requirements.
SAE/AISI 1045SAE/AISI 4140SAE/AISI 4340EN C45EN 42CrMo4
Mold & Tool Steel
For mold bases, die sets, tooling plates and fixture bases. Machinability depends on hardness and heat-treatment condition.

Other grades are welcome:Send the full grade, material standard, hardness, heat-treatment condition, plate size and drawing requirements so we can confirm feasibility.
Grade Note
Grades from different national standards may have similar properties but are not necessarily equivalent. The grades above are examples of machinable materials; final requirements follow the customer drawing, purchase order and material specification.
Factory & Production
Real Factory. Practical Capacity.
From plate preparation and machining to lifting and dispatch, the main processes take place at our production facility.
Production Capability
Plate Machining Up to Approx. 2.5 m × 5 m
Multiple large gantry mills support large plates, bases and frames for industrial equipment manufacturing.
Plate sawing and milling on site
01
Gantry Machining Equipment
Large gantry milling and surface-grinding machines, supported by overhead cranes, handle large-format plates.
02
Standard Industrial Tolerances
We confirm dimensions and standard industrial tolerances from drawings, then inspect during machining and before delivery.
03
Flexible Order Support
We support small trial batches and larger production orders, including customer-supplied material and drawing-based machining.
Quality Control
Three Inspection Stages Throughout Production
Incoming, in-process and final checks help track machining results. Inspection records can be provided on request.
Incoming Inspection
Verify the material and machining requirements before production begins.
In-Process Inspection
Check dimensions and surface condition at key machining stages.
Final Inspection
Review the finished part before delivery and provide inspection records on request.
