When sourcing perforated stainless steel for industrial or architectural use, AISI 304L stainless steel perforated sheet is one of the most searched and trusted materials worldwide. Many buyers focus on AISI 304L stainless steel perforated sheet price, but accurate purchasing decisions also require clear specifications and weight calculations.
AISI 304L Stainless Steel Perforated Sheet Price
As of early 2026, the FOB China port price for AISI 304L (UNS S30403) stainless steel perforated sheets (ASTM A240/A368 standard, 1.0–3.0 mm thickness, 2–6 mm diameter holes, 40–60% open area, 2B finish, 1220×2440 mm sheets) is 2850–3150 USD per metric ton, with a ±6% price fluctuation based on custom hole patterns, surface treatments, order volume (≥10 tons for bulk pricing), and raw material nickel (LME) price volatility.
What Is AISI 304L Stainless Steel Perforated Sheet?
AISI 304L is the low-carbon version of 304 stainless steel, offering excellent corrosion resistance, improved weldability, and stable mechanical performance. When manufactured into perforated sheets, it combines strength, airflow, filtration, and decorative value.
Key Advantages
Low carbon content (≤0.03%), reducing carbide precipitation
Excellent corrosion and oxidation resistance
Easy forming, cutting, and welding
Hygienic surface for food and medical environments
Long service life with low maintenance cost

How to Calculate the Weight of AISI 304L Perforated Sheet?
Weight calculation is essential for pricing, logistics, and project cost estimation.
Step 1: Calculate Solid Sheet Weight
Formula:
Weight (kg) = Length (m) × Width (m) × Thickness (mm) × 7.93
(7.93 = density of 304L stainless steel, g/cm³)
Step 2: Consider Perforation Open Area
Perforated Sheet Weight Formula:
Actual Weight = Solid Sheet Weight × (1 − Open Area %)
Weight Calculation Example
Sheet size: 1000 × 2000 mm
Thickness: 2.0 mm
Open area: 30%
Solid weight:
1.0 × 2.0 × 2.0 × 7.93 = 31.72 kg
Perforated weight:
31.72 × (1 − 0.30) = 22.2 kg (approx.)
This method allows buyers to accurately estimate shipping weight and total project cost.
