Mild Steel (MS): Standard cold-rolled steel per IS 513/ASTM A1008 with powder coating finish providing 5-10 year service life in indoor/climate-controlled environments (interior corridors, basement mechanical rooms, enclosed stairwells) where moisture exposure is minimal and powder coating protection suffices. Cost advantage: 30-40% savings vs. stainless steel making MS ideal for large-scale commercial projects requiring hundreds of cabinets where budget optimization is critical. Galvanized Mild Steel (MSG): Standard mild steel with hot-dip zinc coating (80-120 GSM per IS 277/ASTM A653) creating sacrificial corrosion barrier extending outdoor service life to 10-15 years for semi-exposed installations including fire escape stairwells with partial weather exposure, covered walkways, building perimeters protected by canopies, and coastal locations beyond 5km from seawater. Cost premium: 15-20% vs. standard MS but avoids 200-300% stainless steel cost increase. Selection guidance: Choose MS for indoor installations in air-conditioned buildings, office complexes, residential towers with internal corridors. Choose MSG for outdoor/semi-exposed locations, fire escapes, covered but open-air walkways, or buildings within 5-10km of coastline where moderate corrosion resistance justifies galvanizing premium.

14-Gauge (1.9mm): Heavy-duty specification for industrial facilities, high-traffic commercial installations, vandalism-prone public areas (transit stations, educational institutions), or installations near material handling equipment where maximum dent/impact resistance is required. Cost: Baseline premium gauge. 16-Gauge (1.5mm): Standard commercial grade for typical building applications (hotels, hospitals, office towers, shopping malls) balancing structural strength and cost-effectiveness. Cost: 10-15% savings vs. 14-gauge while maintaining adequate rigidity for 15-30kg equipment load. Most commonly specified thickness. 18-Gauge (1.2mm): Economical option for residential complexes, light-duty office buildings, low-traffic environments where equipment protection rather than cabinet abuse-resistance drives specification. Cost: 20-25% savings vs. 14-gauge. Suitable for budget-conscious developers. 20-Gauge (0.9mm): Ultra-economical for retrofit projects, temporary facilities, or applications where fire code compliance at minimum cost is priority. Cost: 30-35% savings vs. 14-gauge but reduced dent resistance. Recommendation: Specify 14G for industrial/high-traffic, 16G for standard commercial (most versatile choice), 18G for residential/office, 20G for budget retrofit projects.

Expected Service Life: 5-10 years for indoor MS powder coated cabinets in climate-controlled environments (typical commercial building corridors, mechanical rooms, basement areas) with proper maintenance. 10-15 years for galvanized MS with powder coating in semi-exposed outdoor locations. Common Coating Failure Causes: (1) Installation damage: Scratches, chips, or gouges during handling/mounting exposing bare metal to atmospheric moisture—prevent with protective packaging and careful installation. (2) Outdoor exposure without galvanizing: Standard MS powder coating alone insufficient for weather exposure—specify MSG galvanized for outdoor locations. (3) Coastal salt spray: Aggressive corrosion within 5km of seawater exceeds MS/MSG capability—specify SS304 for coastal installations. (4) Lack of maintenance: Neglecting annual inspection and touch-up of minor coating damage allows rust propagation. (5) Improper surface preparation: Inadequate phosphating/degreasing reduces adhesion—ensure supplier has 7-tank phosphate line. Prevention: Annual visual inspection per NFPA 25, immediate touch-up of chips/scratches using manufacturer-supplied touch-up paint matching RAL color, avoid installation in direct weather exposure without galvanizing, specify MSG for semi-exposed locations, consider SS304 upgrade for coastal buildings within 5km of seawater.

Yes, mild steel is susceptible to oxidation (rust) when powder coating barrier is compromised through scratches, chips, or coating failure, exposing bare metal to atmospheric moisture and oxygen. Troubleshooting Rust Appearance: (1) Surface rust (orange discoloration) without coating damage: Indicates moisture condensation on intact coating—wipe clean with dry cloth, inspect humidity control in installation location, ensure adequate ventilation. Non-structural issue. (2) Rust at coating chip/scratch: Most common scenario from installation damage or impact—immediate action required: Wire brush loose rust, clean with degreaser, apply zinc-rich primer (cold galvanizing compound), finish with touch-up paint matching RAL color (request from supplier). Prevents rust spreading under adjacent coating. (3) Extensive rust/coating delamination: Indicates improper surface preparation during manufacturing, inadequate phosphating, or outdoor installation without galvanizing—contact supplier for warranty claim if within 12 months, otherwise consider cabinet replacement. (4) Rust inside cabinet: Indicates moisture intrusion through door seal failure or missing weather seal in semi-exposed location—inspect door gasket, replace EPDM seal if damaged, verify installation location is appropriate for non-galvanized specification. Prevention: Specify galvanized MS for any semi-exposed locations, protect cabinets during construction phase, conduct annual inspections with immediate touch-up of minor coating damage, avoid installation in direct weather exposure.

Manufacturing Lead Times: 2-3 weeks for standard size configurations (450×600, 750×600, 900×600, 450×1200 mm) in mild steel or galvanized mild steel with standard gauge (14/16G) and finishes (fire red, safety yellow, white powder coating). Custom dimensions, special gauge combinations (18/20G), tempered glass doors, or specialized door configurations require 3-4 weeks manufacturing time.
