6. Class A vs Class B vs Class C MS Pipes: Which One Should You Buy?
IS 1239 standards ke under MS Round Pipes ko unki wall thickness ke aadhar par 3 main categories me divide kiya gaya hai:
1. Class A (Light Duty - Yellow Band): Light structural work, solar panel mounting structures, temporary fencing, aur general fabrication ke liye best hai. Low pressure applications me cost save karta hai.
2. Class B (Medium Duty - Blue Band): Plumbing lines, standard water supply, gas pipelines, aur residential construction me sabse jyada istemal hone wala grade hai.
3. Class C (Heavy Duty - Red Band): Firefighting systems, high-pressure steam lines, chemical process plants, aur heavy industrial load structures ke liye mandatory specification hai.
