Selection notes
Uncoated mild steel needs a corrosion plan. Paint, powder coating, galvanizing and process contamination requirements should be separate specification fields.
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
A formable and economical base material for welded mesh, reinforcement and fabricated screens. For Mild 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.
