What is the difference between Hot Dip Galvanized Metal and Galvanized Metal
There does exist a sharp difference between hot dipped galvanized metal and galvanized objects like nails. The new standard that is being used for the pressure treated lumber, according to ACQ states, chemicals which are used in ACQ are likely to corrode the ordinary galvanized fasteners. Hence, special consideration is an absolute must when using ACQ lumber. ACQ is to be used with stainless steel or hot dipped fasteners. Electro-galvanized is a phrase which many may have come across.
Words such as galvanized could be imprecise expect for any specific context. Professionals are likely to state ‘galvanized’ to exactly mean ‘hot dip galvanized’ instead of zinc electroplated (electro galvanized). The latter is a term which is never used by the professionals.
According to many professionals, this term is not required to be used, since, it means the same thing like that of ‘zinc electroplated’. It is regarded to be a term that has been used, accepted and understood universally for ages. It is even stated that probably ‘electro-galvanized’, the term is probably coined by any salesman. This is perhaps to help the company that has been offering less durable and far less expensive zinc electroplating to sail smoothly and pass on the products as superior quality ones.
It could be that during construction of a hospital building, the outlet boxes present in the wall need to be sheradized or hot dipped galvanized. The boxes are stated to be zinc plated galvanized manufactured. Is there a need to get the boxes to be hot dipped or simply have the architect convinced they are quite fabulous just the way it seems to be. Since the building is to be a hospital, where there is expected to be used crucial life support equipment, the architect is sure to be concerned about the zinc whiskers. It is regarded to be a stress phenomenon, where the zinc electroplated surfaces can be a definitive subject and the galvanized surfaces have been believed to be quite less.
The hot dipped galvanized metal specifications may appear on the electrical materials due to outdated specifications. Manufacturers are forced by clean air regulations to adopt the new processes, while construction specifications are not noticed to keep up with such requirements.
Moreover, hot dip galvanizing is known to change thread dimensions. However, it is quite common for cutting threads and allows dimensional change.
