Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer established in 1998 with an annual export value of US$5-10 million. We proudly present our Stainless Steel Diamond Mesh 304 with 1.2mm wire diameter and 20mm opening, each roll accompanied by a mill test report and backed by a 1-year warranty. This product is meticulously crafted to meet the highest standards of durability and precision, making it an ideal choice for demanding industrial, architectural, and security applications. Our commitment to quality and reliability has earned us a strong presence in markets across North America, South America, Europe, Asia, Africa, and Oceania.
The diamond mesh is manufactured from premium grade 304 stainless steel, ensuring excellent corrosion resistance, tensile strength, and long service life. The 1.2mm wire diameter strikes a perfect balance between rigidity and flexibility, while the 20mm diamond-shaped openings provide optimal visibility and airflow without compromising security. Each mesh sheet is expanded (not woven) to create a uniform diamond pattern that offers superior structural integrity. The mill finish surface is clean, smooth, and ready for further processing such as painting, powder coating, or galvanizing, although the natural stainless steel appearance already delivers a sleek, modern look.

Product Features & Benefits
- Superior Corrosion Resistance: Grade 304 stainless steel provides excellent resistance to rust, oxidation, and chemicals, making it suitable for outdoor, marine, and food processing environments.
- High Strength-to-Weight Ratio: The diamond expansion process creates a rigid structure that can withstand heavy loads while remaining lightweight, reducing installation costs and structural support requirements.
- Uniform Openings: The 20mm diamond pattern ensures consistent spacing for ventilation, light transmission, and visibility, ideal for safety barriers, machine guards, and architectural facades.
- Easy Fabrication: The mesh can be cut, bent, welded, or formed into various shapes without losing its integrity. Custom sizes and shapes are available upon request.
- Low Maintenance: Stainless steel 304 requires minimal upkeep; occasional cleaning with mild detergent restores its original luster. No painting or coating is needed for most applications.
- Mill Test Report Included: Each batch is accompanied by a certified mill test report verifying chemical composition and mechanical properties, ensuring full traceability and compliance with international standards.
- 1-Year Warranty: We stand behind the quality of our product. Any manufacturing defects or material issues will be covered within one year from the date of shipment.

Frequently Asked Questions
-
Q: What is the difference between expanded diamond mesh and woven wire mesh?
A: Expanded diamond mesh is made by cutting and stretching a solid metal sheet, creating a one-piece structure with diamond-shaped openings. It is stronger and does not unravel, while woven mesh is made by interlacing wires and may have loose ends. -
Q: Can this mesh be used outdoors without additional coating?
A: Yes, 304 stainless steel offers good corrosion resistance for most outdoor environments. However, in coastal or highly corrosive areas, we recommend 316 stainless steel or a protective coating. -
Q: Do you offer custom sizes and shapes?
A: Absolutely. We can cut or fabricate the mesh to your specific dimensions, including different sheet sizes, curved panels, or pre-formed guards. Minimum order quantities may apply. -
Q: How is the mill test report provided?
A: The mill test report is issued by the steel mill and includes the chemical composition, mechanical properties, and heat number of the raw material. A copy is included with each shipment, and we can send it electronically upon request. -
Q: What is the lead time for an order?
A: For standard sizes, lead time is typically 15-20 days after deposit. Custom orders may require 25-30 days depending on complexity. We ship via sea, air, or express as per your preference. -
Q: Is the 1-year warranty applicable to all defects?
A: The warranty covers manufacturing defects such as improper expansion, material flaws, or dimensional inaccuracies. It does not cover damage caused by misuse, improper installation, or environmental factors beyond normal use. -
Q: Can I get a sample before placing a bulk order?
A: Yes, we provide free samples (A4 size or small cut piece) for evaluation. The buyer only needs to cover the shipping cost. Please contact us to arrange. -
Q: What payment methods do you accept?
A: We accept T/T, L/C, Western Union, and PayPal for small orders. For large shipments, T/T (30% deposit, 70% before shipment) is preferred.
