Handrail
A handrail is a rail that is designed to be grasped by the hand so as to provide safety or support. In Great Britain, Britain, handrails are referred to as banisters. Handrails are commonly used while ascending or descending stairways and escalators in order to prevent injurious falls, and to provide bodily support in bathrooms or similar areas. Handrails are typically supported by balusters or attached to walls. Similar items not covered in this article include grab bar, bathroom handrails—which help to prevent falls on slippery, wet floors—other grab bars, used, for instance, in galley (kitchen), ships' galleys, and barre (ballet), barres, which serve as training aids for ballet dancers. Guard rails and balustrades line drop-offs and other dangerous areas, keeping people and vehicles out. British specifications British Standard and British Standard Code of Practice are harmonized to European Normal (EN) series. Handrail height is set between . US specifications Dimens ...

Escalator
An escalator is a moving staircase which carries people between floors of a building or structure. It consists of a Electric motor, motor-driven chain of individually linked steps on a track which cycle on a pair of tracks which keep the step tread horizontal. Escalators are often used around the world in places where elevator, lifts would be impractical, or they can be used in conjunction with them. Principal areas of usage include department stores, shopping malls, airports, list of transit systems, transit systems (railway/railroad stations), convention centers, hotels, arenas, stadiums and public buildings. Escalators have the capacity to move large numbers of people. They have no waiting interval (except during very heavy traffic). They can be used to guide people toward main exits or special exhibits and may be weatherproofed for outdoor use. A non-functional escalator can function as a normal staircase, whereas many other methods of transport become useless when they ...

Guard Rail
Guard rails, guardrails, railings or protective guarding, in general, are a boundary feature and may be a means to prevent or deter access to dangerous or off-limits areas while allowing light and visibility in a greater way than a fence. Common shapes are flat, rounded edge, and tubular in horizontal railings, whereas tetraform spear-headed or ball-finialled are most common in vertical railings around homes. Park and garden railings commonly in metalworking feature swirls, leaves, plate metal areas and/or Motif (visual arts), motifs particularly on and beside gates. High security railings (particularly if in flat metal then a type of palisade) may instead feature jagged points and most metals are well-suited to anti-climb paint. A handrail is less restrictive on its own than a guard rail and provides support. Public safety Many public spaces are fitted with guard rails as a means of protection against accidental falls. Any abrupt change in elevation where the higher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barre (ballet)
A barre () is a stationary handrail that provides support for people during various types of exercise. Barres are used extensively in ballet training and warming up, warm up exercises, where such exercises are commonly referred to as ''barre work''. In a ballet class, barre may also refer to the part of the class that involves barre work. Barres are also used for warm up exercises in other types of dance, as well as in general fitness programs. Construction The design of a barre—which includes both the handrail and its support mechanism—depends on whether the barre is to be portable or permanently located. A permanent barre typically consists of a handrail that is mounted to and supported by a wall, whereas a portable barre consists of a handrail mounted onto a rigid or adjustable, free-standing supporting structure. Barre height is typically near waist level of a dancer. Some barres have two parallel handrails at different heights to accommodate people of differing height ...

Stairway
A stairwell or stair room is a room in a building where a stair is located, and is used to connect walkways between floors so that one can move in height. Collectively, a set of stairs and a stairwell is referred to as a staircase or stairway. In buildings with several housing units, a stairway can be a necessary common area for getting to and from apartments. Staircases provide vertical access to connected floors in a multi-story building, and are a functional part of it. Stairwells are often used to place several staircases vertically, one above the other. The entrance to elevators is often located in the stairwell. Sometimes the stairwell goes around the lift shaft, other times it is placed next to it. A ''landing'' platform area is generally provided at both ends of a staircase, rather than having a long series of steps that directly leads to a doorway without a flat area between the steps and the door. Minimum requirements for landing platforms are typically established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mobile Safety Steps
Mobile safety steps, sometimes called warehouse steps, are mobile structures with steps up to a platform. The steps use wheels or casters, making them easy to move. They have the advantage over standard ladders in that the operative can have one hand free when moving up and down the steps and both hands free if there is a top-level platform. Variations On smaller steps (between 2 and 6 steps) there will be a handrail and castors which retract when weight is applied, making them stable. They are often used in schools, offices, hospitals, stores and libraries. If they are between 4 and 15 steps they will often be configured to have a top platform (on what would be the final step), and will have surrounding handrails – this style of safety step can be used at a maximum working height of 5 metres. Because they are very sturdy and easy to move, they have a wide variety of uses – for example, in a warehouse (for safe order picking) DIY Hardware store and various types of factorie ...

Balustrade
A baluster () is an upright support, often a vertical moulded shaft, square, or lathe-turned form found in stairways, parapets, and other architectural features. In furniture construction it is known as a spindle. Common materials used in its construction are wood, stone, and less frequently metal and ceramic. A group of balusters supporting a guard railing, coping, or ornamental detail is known as a balustrade. The term baluster shaft is used to describe forms such as a candlestick, upright furniture support, and the stem of a brass chandelier. The term banister (also bannister) refers to a baluster or to the system of balusters and handrail of a stairway. It may be used to include its supporting structures, such as a supporting newel post. In the UK, there are different height requirements for domestic and commercial balustrades, as outlined in Approved Document K. Etymology According to the ''Oxford English Dictionary'', "baluster" is derived through the , from , from ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hanging Strap
In urban public transport, provision is made for standing passengers, often called straphangers or standees, to rationalize operation and to provide extra capacity during rush hour. On crowded rapid transit urban lines, while most travelers may be seated during off-peak services, only a limited proportion will be seated during the peak services. The longer the journey, the less willing passengers are to stand. On intercity rail or coach services, the willingness among passengers to stand is often low, or it may even be prohibited, with reserved seating to ensure that all passengers can be seated. Furthermore, there are also modes of public transport where standing is always prohibited in the vehicle, including school buses, gondola lifts, and amusement park railways. In aviation, safety measures require all passengers and crew to be seated with their seat belts fastened during taxiing, take-off, landing, and turbulence, so airlines do not allow passengers to travel without a ...

Stainless Steel
Stainless steel, also known as inox, corrosion-resistant steel (CRES), or rustless steel, is an iron-based alloy that contains chromium, making it resistant to rust and corrosion. Stainless steel's resistance to corrosion comes from its chromium content of 11% or more, which forms a Passivation (chemistry), passive film that protects the material and can self-healing material, self-heal when exposed to oxygen. It can be further alloyed with elements like molybdenum, carbon, nickel and nitrogen to enhance specific properties for various applications. The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into Sheet metal, sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for ch ...

Brass
Brass is an alloy of copper and zinc, in proportions which can be varied to achieve different colours and mechanical, electrical, acoustic and chemical properties, but copper typically has the larger proportion, generally copper and zinc. In use since prehistoric times, it is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, a copper alloy that contains tin instead of zinc. Both bronze and brass may include small proportions of a range of other Chemical element, elements including arsenic, lead, phosphorus, aluminium, manganese and silicon. Historically, the distinction between the two alloys has been less consistent and clear, and increasingly museums use the more general term "list of copper alloys, copper alloy". Brass has long been a popular material for its bright gold-like appearance and is still used for drawer pulls and door handle, doorknobs. It has also been widely used to ma ...

Aluminium
Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has a great affinity towards oxygen, passivation (chemistry), forming a protective layer of aluminium oxide, oxide on the surface when exposed to air. It visually resembles silver, both in its color and in its great ability to reflect light. It is soft, magnetism, nonmagnetic, and ductility, ductile. It has one stable isotope, 27Al, which is highly abundant, making aluminium the abundance of the chemical elements, 12th-most abundant element in the universe. The radioactive decay, radioactivity of aluminium-26, 26Al leads to it being used in radiometric dating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ ...
