Embossing

Embossing

Many architectural materials are embossed for beauty and appearance.  Metals can be embossed and painted to look like wood.  The inside of an elevator has embossed material. Some cold rolled is rolled with a satin finish so that it has more area to fuse to the paint or galvanized surface.  Spiral grooves are embossed on the inside of copper tubes as used in air conditioning and refrigeration.  There are spiral grooves on the inside of some boilers and heat exchangers.  This allows the area within the tube to be substantially increased in area, and at the same time, creates turbulence to improve the boiler or heat exchanger without increasing the cost of the metal.  It also reduces the cost and size of the boilers or heat exchangers.

Any unusual embossed design can be performed on a rolling mill with enough separating force to create the embossed area.  In fact, there are hand crank machines that take a penny and emboss a message on it.  Embossing can produce a surface that will not stain and is easy to clean.  Embossing improves the appearance of the material in some instances.  Again, embossing improves the surface area of the material, which can allow for more transfer of heat per square area.
