Industrial Safety Nets IS 11057

Industrial safety nets are widely used in construction sites for people working on high-rise buildings, building maintenance, or other industries.


BIS is a statutory institution established under the Bureau of Indian Standards Act,1986  to promote harmonious development of the activities of standardization, marking and quality certification of goods and attending to connected matters in the country.
