Special earthquake-resistant reinforcements designed to withstand and mitigate large-scale structural movements in all kinds of structures, in the event of an earthquake or very sudden thermal expansion, these reinforcements absorb the shocks of slabs and help support the loads so that The construction does not suffer structural damages.
Characteristics
– The lifetime of the board is about 20 years.
– Ozone resistant and most chemical oxidants.
– They are designed to withstand heavy loads, for large movements, especially earthquakes.
