    • Flats
    • Tubes
    • Z-sections
    • T-sections
    • Muliums
    • Angles
    • H-beams
    • I-sections
    • Channels
    • Weld mesh
    • Chain link
    • Many other composite

The temporary electrical connections given at site should be proper and not hanging. All the machinery and the job should be earthed properly before starting the work to avoid accidents.


  1. It should be as per drawings and
  2. Material should be as per standard quantity and weight
    • Correct measurement for grills/railings should be taken at

  5. Grills/railings should be fixed at places with proper anchoring bolts/screws using plastic rawal
    • Check the line level and
    • Final coat of approved shape should be applied later
