A product, is the end result of a production process, and usable in its own right. Thus a brick is a product, as is a structural steel section, and SIP's, and likewise a water tank and a garden shed.
The public typically doesn't want to waste time on design and engineering, and wants development approval and building permits to be issued as quickly as possible. They therefore go to manufacturers of sheds. But then start to introduce variations, imposing a need for custom design and engineering.
So have an industry that emerges based on selling a product, but otherwise is really selling a building system. However, given that I have a generic sense of product and process, the building system is also a product.
When I originally created the two groups, the idea was one be focused on cold-formed steel sheds and similar buildings, and this group here be for everything else. But there are too many generic issues across all the products and systems, that I don't want to repeat topics.
A SIP is a product in its own right, it may be used to construct a larger building assembly, which is also a product in its own right, or it may be included as a component in a building system.
The issue for this group is that the SIP is useless, and cannot become a part of larger assembly or building system, unless it has a proper technical specification. A stock standard building built from SIP's is also useless unless it has a proper technical specification. The technical specification is required in order to assess the suitability of the SIP for installation in some larger assembly. For the building a technical specification is required to assess the site specific and environmental parameters, along with actual building purpose and select an appropriate building fit-for-function.
So decided to return to original focus of structural products that are manufactured, also not overly concerned whether classed as building: since also relates to water tanks, scaffolding, industrial racking, bridges and multitude of other structures.
The issue is expect to buy off-the-shelf and put to use with no formal design input, no custom features are permitted which influence structural performance.
Apologies for any inconvenience, but this should be the last change for the name of this group.
