LEAD PLATES AND SHEETS
The lead sheets and foils are rolled of soft lead Pb99,97 or Pb99,985, which corresponds to DIN 1719 standard, or they are rolled of lead alloyed with copper, which corresponds do DIN 17640 or BS 1178 standards, or possibly they may be rolled of lead alloys doped with antimony, tin, silver, etc.
The lead sheets and foils are also produced as single-sided or double-sided tin-clad lead sheets or foils.
Mechanical engineering utilisation:
- thick lead plates are used as weights
- thin sheets may be used as gaskets (for example pump’s flanges, pipes)
Health service utilisation:
- shielding of X-rays cabinets (the doors are covered with lead sheet)
Nuclear industry utilisation:
- gamma rays shielding
Chemical industry utilisation:
- reaction tanks inner coats
- production of anodes for electroplating
Measuring equipment utilisation:
- the foils are used for X-rays photography
Lead sheets as a construction material:
- advantages:
- the resistance against atmospheric influence
- the resistance against aggressive substances
- very good ductility
- suitable electric potential of lead with respect to other metals
- usage:
- roofing
- material for sheetmetal work
- termination of walls
- termination of roof intersections
- sheating
- protection against the penetration of radon
- connecting skylights with roofing
- size standards:
- DIN 59610
- BS 1178
- 0,5 mm a 0,6 mm x 150 mm až 500 mm x production
- length (skylights)
- colours - brown RAL 8016, gray RAL 7022 (the maximum length is 2500 millimetres, width 500 mm)
