For a 3.6m opening in a 6.3m wall of 200mm Celcon blocks I will need reinforcement. The wall will be internal and loadbearing but I would prefer stainless steel reinforcement rather than galvanised or expamet type as it is structural rather than crack control
I am looking at 3mm ladder type but this only comes in 2.7m lengths and width max is 100mm. I understand the reinforcement should extend 600mm beyond the opening. I asked the manufacturer what they recommend but their reply was that there were no standards set.
What width should the reinforcement be for a 200mm block wall and what overlap should there be at the centre. Also how many rows above and below the lintels?
