The building materials for most projects are gotten from the local building supply store. Sometimes a special project or need can cause problems with planning. Any room or area that needs specific fire requirements or airtight/watertight design are examples of a challenge in building. These obstacles are often overcome by a creative architect or builder through changes in structure and design but that is sometimes the long way around.
With use of enough rivets and supports a metal facing can be placed on most any framework. Some additional expenses and labour from a qualified tin knocker will be involved and ultimately the design will need to be done in a manner that conventional sheet metal can be used. There are alternatives to this if you want or need something different.
Common projects that this becomes a factor in are paint booths, custom walk-in coolers or refrigeration units of large scale, and some industrial food service or preparation applications. When confronted with these situations instead of relying on local construction knowledge and ability look into actual sheet metal shops. While certain angles, curves, and corner designs are nearly impossible for onsite fabrication, a good metal workers shop can do nearly anything needed off site and then simply have it installed at the location.
A good metal fabrication shop has the equipment to do tailored pieces of sheet metal with custom bends and corner seals. Since they regularly do things like match body pieces for classic cars exactly getting the exact specified measurements for other applications is well within their abilities.
When deciding and comparing costs of different ways to meet a need, getting a quote from a custom metal fabricator may end up saving substantial money over changing a design. This is especially true when trying to match or build onto existing areas which would require substantial demolition to do in another manner. If the metal is prefabricated so it needs only basic installation then there is less labour required for on-site customization. The end result is a cleaner better job at similar or even lower costs.
Having the right expert look at the situation is the key. A carpentry person looks at what they are familiar with to give an idea. If you are looking at metal applications having somebody that specializes in custom metal is a better choice.
