Hastelloy Expanded Metal Options
We offer several forms of Hastelloy expanded metal, each designed to meet specific application needs.
Standard Hastelloy Expanded Metal
Standard Hastelloy expanded metal features a raised surface that enhances grip and skid resistance, making it ideal for walkways, platforms, and ramps. Its open design allows for easy airflow, light passage, and drainage. The inherent strength of Hastelloy ensures durability in high-pressure and high-temperature environments.
Flattened Hastelloy Expanded Metal
Flattened Hastelloy expanded metal provides a smooth surface, suitable for applications where aesthetics and uniformity are important. It is often used in architectural elements such as facades and decorative panels. The flattening process maintains the corrosion resistance and structural integrity of the material while slightly reducing thickness.
Hastelloy Expanded Metal Grating
Designed for heavy-duty applications, Hastelloy expanded metal grating is used for industrial flooring, platforms, and stair treads. It offers excellent load-bearing capacity and maintains safety and stability in corrosive and high-temperature environments. This form is particularly valuable in industries such as marine, chemical processing, and power generation.
