Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with an annual export value exceeding US$5 million. Our 304 Filter Mesh 0.5mm Opening 0.25mm Wire Diameter 12m×1m Roll Tensile 800N/mm is engineered to deliver precise filtration and long-lasting durability. Whether you're in chemical processing, food & beverage, or water treatment, this mesh offers consistent performance and reliable quality.
Crafted from premium 304 stainless steel, this filter mesh features a 0.5mm square opening and a 0.25mm wire diameter, resulting in a precise balance between flow rate and particle retention. The 12m×1m roll format provides ample material for industrial applications, while the exceptional tensile strength of 800N/mm ensures it withstands high-pressure environments without deformation.
Key Features & Benefits
- Precision Filtration: 0.5mm opening effectively captures particles of 0.5mm and larger, ideal for sieving, straining, and filtering applications.
- High Tensile Strength: 800N/mm tensile rating ensures the mesh maintains its shape under heavy loads and high flow rates, reducing downtime.
- Corrosion Resistance: 304 stainless steel offers excellent resistance to oxidation, acids, and alkalis, making it suitable for both wet and dry environments.
- Easy Installation: Supplied in a 12m × 1m roll, you can cut to size with standard tools, saving time and waste.

Frequently Asked Questions
Q1: What is the exact opening size of this mesh?
A: The opening is 0.5mm (500 microns) square, measured from wire center to center. This allows particles larger than 0.5mm to be retained.
Q2: Can this mesh be used for liquid filtration?
A: Yes, the 304 stainless steel is corrosion-resistant and suitable for both liquid and dry filtration. The open area of about 44% provides good flow rates.
Q3: Is the mesh supplied in a single continuous roll?
A: Yes, each roll is 12 meters long and 1 meter wide, wound continuously for easy handling and cutting to your required lengths.
Q4: What is the maximum temperature this mesh can withstand?
A: 304 stainless steel typically handles up to 870°C (1600°F) in oxidizing environments, but continuous use at high temperatures may reduce tensile strength. For extreme heat applications, please consult us.
Q5: Can I get custom sizes or different wire diameters?
A: Absolutely. We offer customization options including varying roll dimensions, wire diameters, and weave patterns. Contact our sales team with your requirements.
Q6: How is the mesh packaged for export?
A: Each roll is wrapped in protective plastic and then packed in sturdy cartons or wooden pallets, depending on order quantity. We ensure safe transit to the port.
Q7: What is the lead time for this product?
A: For standard rolls, lead time is 7–15 days after order confirmation. Large volumes may require 20–30 days. We can expedite if needed.
Q8: Do you offer free samples?
A: Yes, we can provide small samples (e.g., 1m × 1m) for evaluation. Freight charges may apply, but we can deduct them from a future order.
