COATINGS |
|
A coating is a covering that is applied to an object to protect it or change its appearance. They may be applied as liquids, gases or solids.
Examples of coatings:
Anodizing
Chemical vapor deposition and physical vapor deposition
Chromate conversion coating
Enamel (paint)
Industrial coating
Oxide (coating)
Paint
Plasma coatings
Electroless plating or electrochemical plating
Phosphate (coating)
Polymer coatings, such as Teflon
Sputtered or vacuum deposited materials
Plate steel is often ordered from the mill pickled and oiled)
Enamel (vitreous)
Fusion bonded epoxy coating (FBE coating)

DEMOLITION |
|
Demolition is the opposite of construction: the tearing-down of buildings and other structures. It is contrasted with deconstruction, which is the taking down of buildings while carefully preserving valuable elements for re-use.

ESCALATOR |
|
An escalator is a conveyor transport device for transporting people, consisting of a staircase whose steps move up or down on tracks that keep the surfaces of the individual steps horizontal.
A moving walkway, moving sidewalk, travelator, or travellator is a slow conveyor belt that transports people horizontally or on an incline in a similar manner to an escalator. In both cases, riders can walk or stand. The walkways are often supplied in pairs, one for each direction.

FLOOR COVERING |
|
Flooring is the general term for a permanent covering of a floor. It is usually used to mean parquetry, but it can also refer to carpets, laminate flooring, raised flooring, and linoleum. Most wooden floors are made out of hard woods to prevent denting though most people today have carpets.
Floor covering selection, installation, repair, accident prevention, slip and fall information.

HVAC - HEAT VENTITATION AIR CONDITIONING |
|
HVAC (pronounced either "H-V-A-C" or, occasionally, "H-VAK") is an initialism/acronym that stands for "heating, ventilation and air-conditioning". This is sometimes referred to as climate control.
These three functions are closely interrelated, as they control the temperature and humidity of the air within a building in addition to providing for smoke control, maintaining pressure relationships between spaces, and providing fresh air for occupants. In modern building designs, the design, installation and control systems of these functions are integrated into a single "HVAC" system.
The term air handler can mean a whole unit including the blower, heating and cooling elements, filter racks or chamber and dampers, but not including the ductwork through the building.

PLASTICS |
|
Plastic covers a range of synthetic or semisynthetic polymerization products. They are composed of organic condensation or addition polymers and may contain other substances to improve performance or economics. There are few natural polymers generally considered to be "plastics". Plastics can be formed into objects or films or fibers. Their name is derived from the fact that many are malleable, having the property of plasticity. Plastics are designed with immense variation in properties such as heat tolerance, hardness, resiliency and many others. Combined with this adaptability, the general uniformity of composition and light weight of plastics ensures their use in almost all industrial segments.
