Mill finish is the surface texture (or finish) of metal after it exits a rolling mill, extrusion die, or drawing processes, including sheet, bar, plate, or structural shapes. This texture is usually rough and lacks lustre; it may have spots of oxidation or contamination with mill oil.
A #7 finish is produced by polishing with a 280–320 grit belt or wheel and sisal buffing with a cut and color compound. This is a semi-bright finish that will still have some polishing lines but they will be very dull. Carbon steel and iron are commonly polished to a #7 finish before chrome plating.
Anodizing increases resistance to corrosion and wear, and provides better adhesion for paint primers and glues than bare metal does. Anodic films can also be used for several cosmetic effects, either with thick porous coatings that can absorb dyes or with thin transparent coatings that add reflected light wave interference effects.
Designing for the movement of building components due to temperature, loads, and settlement is an important part of architectural detailing. Building expansion joints provide barriers to the exterior and cover spaces between components. Copper is an excellent material for expansion joints because it is easy to form and lasts a long time.
Architectural coatings [1] [2] or paints [3] are paints and other coatings used to paint the exteriors and interiors of buildings, often called or external masonry coatings. Clear varnishes and lacquers are generally excluded. [1] Such products are usually designated for specific purposes such as roof coatings, wall paints, or deck finishes. [2]
Mill scale is thus a boon for a while, until its coating breaks due to handling of the steel product or due to any other mechanical cause. Mill scale becomes a nuisance when the steel is to be processed. Any paint applied over it is wasted, since it will come off with the scale as moisture-laden air gets under it. Thus mill scale can be removed ...

Relative to other building components, aluminum has a high heat transfer coefficient, meaning that aluminum is a very good conductor of heat. This translates into high heat loss through aluminum (or steel) curtain wall mullions. There are several ways to compensate for this heat loss, the most common way being the addition of thermal breaks.
