We've recently had a deck replaced and extended. We had decided to use stainless steel wire balustrades and wanted to put a roof on it. The deck is about 4.5m high. Our contractor was well aware of our intention to use the stainless steel wire balustrades and the desire to put a roof on it. The support posts he installed are Pine Post - Dressed: FJ-Lam Treated H4 GL8 Rougher Header 88x88. We have now been told (by another contractor) that these are not recommended for wire balustrades let alone a roof.
Is this the case? Do we have to replace the support posts to allow for the wire balustrades?
