Frequently Asked Questions
Raised expanded metal has strands that stand up from the sheet, providing higher rigidity and slip resistance. Flattened expanded metal is rolled smooth after expansion, making it ideal for architectural facades and surfaces requiring a flush finish.
For high-corrosion areas, Stainless Steel (304 or 316) is the premium choice. Galvanized Steel is an excellent cost-effective alternative for general outdoor use due to its zinc coating.
It serves as a current collector and electrode grid. Its high conductivity and structural strength ensure efficient electron transfer and mechanical support for active materials in Li-ion and Ni-MH batteries.
Yes, micro-expanded metal is widely used as a pre-filter to capture large debris or as a rigid support frame for delicate filter media like fabric or paper in HVAC and oil systems.
Absolutely. It is highly sustainable as the production process generates zero scrap waste, and the materials used (steel, aluminum, copper) are 100% recyclable.
For maximum load, position the Long Way of Design (LWD) parallel to the clear span. Panels should be bolted or welded every 6 inches to rigid supports with the straight edge facing up.
