Are you looking for a highly reliable, durable, and precise industrial filtration or screening solution? Our premium 30 mesh stainless steel wire mesh (also known as 30 mesh wire cloth or wire screen) offers exceptional structural integrity and outstanding corrosion resistance.<\/p>\n\n\n\n

Whether you need standard food-grade materials or marine-grade alloys for harsh environments, we provide tailor-made woven wire mesh solutions to match your exact specifications.<\/p>\n\n\n\n

What Does “30 Mesh” Mean? (How We Measure It)<\/strong><\/strong><\/p>\n\n\n\n

In the woven wire industry, the term Mesh Count refers to the number of openings or holes per linear inch of the material.<\/p>\n\n\n\n

The Ruler Test: If you place a standard physical ruler on our 30 Mesh screen, you will count exactly 30 holes within a one-inch (25.4 mm) span.<\/p>\n\n\n\n

Because the mesh count is fixed at 30, the actual aperture size (hole clearance) and open area percentage will vary depending on the thickness (diameter) of the wire woven into the mesh. Heavy-duty applications require thicker wires (which reduce the hole size), while high-flow filtration uses thinner wires to maximize the open area.<\/p>\n\n\n\n

Materials: Grade 304 vs. Marine-Grade 316 Stainless Steel<\/strong><\/strong><\/p>\n\n\n\n

We offer two industry-standard stainless steel alloys, each engineered to perform under specific environmental conditions:<\/p>\n\n\n\n

1. Standard Grade 304 Stainless Steel (SS 304)<\/h3>\n\n\n\n

Chemical Profile: 18% Chromium, 8% Nickel.<\/p>\n\n\n\n

Best For: Indoor applications, general sifting, dry food processing, pest control, and standard industrial filtration.<\/p>\n\n\n\n

Key Benefits: High mechanical strength, excellent cost-effectiveness, and rust resistance under normal atmospheric conditions.<\/p>\n\n\n\n

2. Marine-Grade 316 Stainless Steel (SS 316)<\/h3>\n\n\n\n

Chemical Profile: 16% Chromium, 10% Nickel, added 2% Molybdenum.<\/p>\n\n\n\n

Best For: Coastal environments, saltwater filtration, chemical processing, and highly acidic\/alkaline sifting.<\/p>\n\n\n\n

Key Benefits: The addition of molybdenum drastically improves resistance to chloride pitting, crevice corrosion, and chemical attacks.<\/p>\n\n\n\n

Versatile Applications of 30 Mesh Screen<\/strong><\/strong><\/h2>\n\n\n\n

With average opening sizes ranging from 0.496mm (496microns) to 0.726 mm (726 microns), 30 mesh is incredibly versatile. It is widely adopted across multiple commercial, industrial, and residential sectors:<\/p>\n\n\n\n

Liquid & Oil Filtration: Highly trusted for biodiesel oil filtration, oil-water separation, and custom industrial kettle filters.<\/p>\n\n\n\n

Beverage & Brewing: An essential component for making fine tea strainers, reusable coffee filters, homebrew mash filters, and brewing hop stoppers.<\/p>\n\n\n\n

Food Powder Grading & Sifting: Perfectly sized to sift and separate kitchen staples like dry table salt and fine ground black pepper without clogging.<\/p>\n\n\n\n

Pest Control & Horticultural Protection: Used outdoors as physical, non-chemical barriers for slug proofing and heavy-duty, chew-proof insect screening in green spaces.<\/p>\n\n\n\n

Architectural & Design Elements: Selected by architects as high-end decorative and cosmetic mesh panels, cabinetry vent grilles, and fireplace spark screens.<\/p>\n\n\n\n

Frequently Asked Questions (FAQs)<\/strong><\/strong><\/p>\n\n\n\n

Q1: What micron rating corresponds to a 30 mesh stainless steel screen?<\/p>\n\n\n\n

The micron rating depends entirely on your choice of wire diameter. For 30 mesh, the micron rating ranges from 496 microns to 726 microns. If you need a custom micron rating, our engineering team can help you select the exact wire diameter required.<\/p>\n\n\n\n

Q3: How do I choose between SS 304 and SS 316 for food-grade filtration?<\/p>\n\n\n\n

Both SS 304 and SS 316 are considered safe for food contact. However, if you are filtering highly acidic food products (like citrus juices) or handling salty brines, SS 316 is highly recommended to prevent long-term corrosion.<\/p>\n\n\n\n
