Product Introduction
Engineered for Molten Metal Filtration Excellence
Coated Fiberglass Fabric Foundry Filter Rolls are specialized high-temperature filtration media designed for rigorous foundry and metalcasting applications. Featuring a heat-resistant fiberglass base with a proprietary coating, these rolls deliver unmatched thermal stability, slag capture efficiency, and extended service life in contact with molten ferrous / non-ferrous metals. Ideal for replacing ceramic foam filters in gating systems.
Performance Characteristics
- Extreme Temperature Resistance: Withstands continuous exposure to 1,200°C (2,192°F) and thermal shocks from rapid metal pouring.
- Superior Metal Filtration: Coating technology captures micro-inclusions (slag, oxides >50μm) while maintaining 85-92% metal yield vs. 70-80% for ceramic filters.
- Non-Wetting Surface: Proprietary coating prevents molten metal adhesion, reducing filter blockage and cleaning downtime.
- High Mechanical Strength: Reinforced weave retains structural integrity under metal flow pressure (tested to 0.8 MPa).
- Fast Installation & Customization: Supplied in rolls for on-site die-cutting; customizable widths (200mm–1,500mm) and pore densities (10–40 PPI).
- Zero Contamination: Inorganic coating eliminates gas generation – no hydrogen pickup in aluminum/copper alloys.
- Certified Safety: Complies with ISO 12677 (foundry filter testing) and ROHS/REACH standards.

Why Choose Our Coated Fiberglass Fabric Foundry Filter In Roll?
Unleash Peak Performance: The Unmatched Advantages of Firstclass Coated Fiberglass Mesh Filters
For over two decades, Firstclass Import & Export has been at the forefront of engineering high-performance industrial materials. Since 2002, our commitment to innovation and quality has made us a trusted partner in the most demanding sectors, including aerospace, military, and nuclear power. We bring this same legacy of excellence to our coated fiberglass fabric mesh filters, supplied in convenient rolls for superior application flexibility.
Our coated fiberglass mesh filters are not just a product; they are a precision-engineered solution designed to excel where others fail. Here's why they are the preferred choice for industry leaders:
Leveraging our core expertise in heat-resistant materials, our fiberglass substrate provides inherent non-flammability and can withstand extreme temperatures without compromising its structural integrity. The specialized coating enhances this property, making our filters ideal for high-temperature filtration processes in power generation, metalworking, and chemical manufacturing.
The proprietary polymer coatings applied to our fiberglass mesh create a powerful barrier against a wide range of acids, alkalis, and solvents. This exceptional chemical resistance ensures a long service life even in highly corrosive environments, such as chemical processing plants or wastewater treatment facilities, reducing downtime and replacement costs.
Unlike organic fabrics, fiberglass does not stretch, shrink, or warp under load or variable humidity. Supplied in robust rolls, our mesh filter material maintains its exact shape and pore size, guaranteeing consistent filtration precision and reliable performance from the first foot to the last. This strength ensures it can handle high airflow pressures and physical stress.
We engineer our meshes with precise, uniform weave patterns and controlled coating applications to deliver accurate and repeatable micron retention. This consistency is critical for applications demanding strict purity standards, such as in the pharmaceutical, food & beverage, or nuclear sectors. Every square inch of the roll performs identically.
Supplied in continuous rolls, our coated fiberglass fabric offers unparalleled flexibility for integration. It can be easily cut to size, sewn, or fabricated into custom filter bags, cassettes, panels, or sleeves to fit any system, minimizing waste and simplifying inventory management for our clients.
The inherent durability of glass fibers combined with our protective coatings results in a filter media that resists clogging, is easy to clean, and offers a significantly longer lifespan than traditional materials. This translates to lower total cost of ownership, reduced maintenance cycles, and increased operational efficiency.
Engineered for Critical Applications:
From capturing fine particulates in power plant emissions to filtering aggressive chemicals and withstanding intense heat, our coated fiberglass mesh filters in rolls are built to ensure reliability, safety, and performance.
Choose Firstclass for Uncompromising Quality.
