Selection notes
Specify whether galvanizing occurs before or after weaving/welding, coating requirement, cut-edge treatment and expected environment.
Environment
Define moisture, salts, acids, alkalis and cleaning agents.
Fabrication
Cutting and welding can change surface condition and corrosion behaviour.
Verification
Request the alloy designation, applicable certificate and finish in the quotation.
Start with exposure, not grade popularity
Carbon-steel mesh protected by a zinc coating for economical fencing, guards and general service. For Galvanized Steel Wire Mesh, list every process chemical, cleaning agent, contaminant and atmospheric exposure. Include concentration, temperature, duration, deposits and whether the mesh is rinsed or allowed to dry.
Evaluate the finished component
Wire drawing, weaving, welding, cutting, framing and surface treatment can affect the delivered component. A mill certificate identifies material chemistry; it does not prove cleanability, weld finishing, coating continuity or fitness for a particular regulation. Specify both material evidence and fabrication requirements.
Comparison checklist
- Corrosion and oxidation conditions, including cleaning.
- Strength, abrasion, impact, temperature and support arrangement.
- Food, pharmaceutical or other regulatory obligations.
- Magnetism, conductivity, mass or appearance when relevant.
- Exact grade, finish, certificate and substitution rules.
Procurement note
Ask suppliers to identify any alternative grade separately. Compare the complete service life and failure consequence, not only raw material price. Where prior service exists, provide the old grade, time in use, location of attack or wear, and clear photographs.
