Stainless steel sheets are produced through precise manufacturing processes that determine their mechanical properties, surface quality, and dimensional accuracy.

Step 1: Pickling
Hot rolled coils are cleaned in acid baths to remove scale and surface oxides.

Step 2: Cold Reduction
The pickled coils are rolled at room temperature through multiple stands to achieve the desired thickness. This process:

• Improves surface finish

• Achieves tight thickness tolerances (±1%)

• Increases strength through work hardening

Step 3: Annealing
The cold rolled steel is heat treated in controlled atmospheres to restore ductility and relieve internal stresses.

Step 4: Skin Pass / Leveling
A light final rolling pass improves flatness and surface quality.

Step 5: Surface Finishing
Depending on the final application, various finishes (2B, BA, NO.4, 8K, HL) are applied.

Step 1: Heating
Steel slabs are heated to approximately 1100–1200°C, above the recrystallization temperature.

Step 2: Rolling
The red-hot steel passes through roughing and finishing rolling stands to achieve the final thickness.

Step 3: Cooling & Leveling
The rolled steel is cooled and leveled to ensure flatness.

Step 4: Inspection & Cutting
Finished plates are inspected for dimensional accuracy and surface quality, then cut to required sizes.

• Chemical composition analysis

• Mechanical property testing (tensile strength, yield strength, elongation)

• Dimensional inspection (±1% tolerance)

• Surface quality assessment

A:

• 304: General-purpose austenitic stainless steel with good corrosion resistance. Suitable for most applications.

• 316L: Contains molybdenum for enhanced corrosion resistance, especially against chlorides and marine environments. Ideal for coastal, marine, and chemical applications.

• 430: Ferritic stainless steel with lower cost, good corrosion resistance, and magnetic properties. Suitable for decorative and mild industrial use.

A: We offer a comprehensive thickness range:

• Cold rolled: 0.2mm – 3.0mm

• Hot rolled: 3.0mm – 14.0mm
  Custom thicknesses are available upon request.

A: We offer multiple surface finishes:

• 2B: Bright, cold rolled finish

• BA: Bright annealed, mirror-like

• NO.4: Brushed finish with linear grain
