Wall Padding
Wall padding may go by a variety of names, including; Softwall, Wainscott, Cushion Wall, Safety Padding, and more. Purpose The primary purpose of wall padding is to provide a safe level of absorption for an individual making impact with an established object. Often these objects are walls (hence “wall padding”), but also these pads commonly protect bleachers, stage fronts, I-Beams, goal posts, columns, and fences. Standard Sizes Typical indoor wall panels are 24” wide x 72” high. In recent history however many newly constructed schools and universities have made a push for 84” high padding in their basketball facilities, where athletes are often elevated in motion. In grappling and wrestling facilities pads are regularly 60” since most movement occurs on the ground. Outdoor stadium padding is 48” wide x 96” high. However, when working with a skilled manufacturer all dimensions can often be easily customized to fit the unique needs of your facility. Compo ...

Bleacher
Bleachers (North American English), or stands, are raised, tiered rows of benches found at sports fields and other spectator events. Stairways provide access to the horizontal rows of seats, often with every other step gaining access to a row of benches. Benches range from simple planks to elaborate ones with backrests. Many bleachers are open to the ground below so that there are only the planks to sit and walk on. Some bleachers have vertical panels beneath the benches, either partially or completely blocking the way to the ground. Name origins The open seating area in baseball was called the "bleaching boards" as early as 1877. The term "bleachers" used in the sense of benches for spectators can be traced back to at least 1889; named as such because the generally uncovered wooden boards were "bleached by the sun". ''The Dickson Baseball Dictionary'' lists as a ''secondary'' definition the fans sitting in them. By the early 1900s, the term "bleachers" was being used for ...

Plywood
Plywood is a material manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. It is an engineered wood from the family of manufactured boards which include medium-density fibreboard (MDF), oriented strand board (OSB) and particle board (chipboard). All plywoods bind resin and wood fibre sheets (cellulose cells are long, strong and thin) to form a composite material. This alternation of the grain is called ''cross-graining'' and has several important benefits: it reduces the tendency of wood to split when nailed at the edges; it reduces expansion and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across all directions. There is usually an odd number of plies, so that the sheet is balanced—this reduces warping. Because plywood is bonded with grains running against one another and with an odd number of composite part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminum
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. 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+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity towards ox ...

Firing Strip
Dismissal (also called firing) is the termination of employment by an employer against the will of the employee. Though such a decision can be made by an employer for a variety of reasons, ranging from an economic downturn to performance-related problems on the part of the employee, being fired has a strong stigma in some cultures. To be dismissed, as opposed to quitting voluntarily (or being laid off), is often perceived as being the employee's fault. Finding new employment may often be difficult after being fired, particularly if there is a history of being terminated from a previous job, if the reason for firing is for some serious infraction, or the employee did not keep the job very long. Job seekers will often not mention jobs that they were fired from on their resumes; accordingly, unexplained gaps in employment are often regarded as a red flag. Usage While the main formal term for ending someone's employment is "dismissal", there are a number of colloquial or euphemistic ...

Cinder Block
A concrete masonry unit (CMU) is a standard-size rectangular block used in building construction. CMUs are some of the most versatile building products available because of the wide variety of appearances that can be achieved using them. Those that use cinders (fly ash or bottom ash) as an aggregate material are called cinder blocks in the United States, breeze blocks (''breeze'' is a synonym of ''ash'') in the United Kingdom, and hollow blocks in the Philippines. In New Zealand and Canada they are known as concrete blocks (a name common in the United States also). In New Zealand, they are also called construction blocks. In Australia, they are known as Besser blocks or Besser bricks, because the Besser Company was a major supplier of machines that made concrete blocks. Clinker blocks use clinker as aggregate. In non-technical usage, the terms ''cinder block'' and ''breeze block'' are often generalized to cover all of these varieties. Composition Concrete blocks are made ...

Nailing Margin
In woodworking and construction, a nail is a small object made of metal (or wood, called a tree nail or "trunnel") which is used as a fastener, as a peg to hang something, or sometimes as a decoration. Generally, nails have a sharp point on one end and a flattened head on the other, but headless nails are available. Nails are made in a great variety of forms for specialized purposes. The most common is a ''wire nail''. Other types of nails include ''pins'', ''tacks'', ''brads'', ''spikes'', and '' cleats.'' Nails are typically driven into the workpiece by a hammer or nail gun. A nail holds materials together by friction in the axial direction and shear strength laterally. The point of the nail is also sometimes bent over or ''clinched'' after driving to prevent pulling out. History The history of the nail is divided roughly into three distinct periods: * Hand-wrought (forged) nail (pre-history until 19th century) * Cut nail (roughly 1800 to 1914) * Wire nail (roughly 1860 to ...

Fire Retardant
A fire retardant is a substance that is used to slow down or stop the spread of fire or reduce its intensity. This is commonly accomplished by chemical reactions that reduce the flammability of fuels or delay their combustion. Fire retardants may also cool the fuel through physical action or endothermic chemical reactions. Fire retardants are available as powder, to be mixed with water, as fire-fighting foams and fire-retardant gels. Fire retardants are also available as coatings or sprays to be applied to an object. Fire retardants are commonly used in fire fighting, where they may be applied aerially or from the ground. Principles of operation In general, fire retardants reduce the flammability of materials by either blocking the fire physically or by initiating a chemical reaction that stops the fire. Physical action There are several ways in which the combustion process can be retarded by physical action: * By cooling: Some chemical reactions actually cool the material d ...

Leather
Leather is a strong, flexible and durable material obtained from the tanning, or chemical treatment, of animal skins and hides to prevent decay. The most common leathers come from cattle, sheep, goats, equine animals, buffalo, pigs and hogs, and aquatic animals such as seals and alligators. Leather can be used to make a variety of items, including clothing, footwear, handbags, furniture, tools and sports equipment, and lasts for decades. Leather making has been practiced for more than 7,000 years and the leading producers of leather today are China and India. Animal rights groups claim that modern commercial leather making and the consumption of its products is unethically killing animals. According to the life-cycle assessment (LCA) report for the United Nations Industrial Development Organization, 99% of the raw hides and skins used in the production of leather derive from animals raised for meat and/or dairy production. Critics of tanneries claim that they engage in uns ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyurethane
Polyurethane (; often abbreviated PUR and PU) refers to a class of polymers composed of organic chemistry, organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials. This chemical variety produces polyurethanes with different chemical structures leading to many List of polyurethane applications, different applications. These include rigid and flexible foams, varnishes and coatings, adhesives, Potting (electronics), electrical potting compounds, and fibers such as spandex and Polyurethane laminate, PUL. Foams are the largest application accounting for 67% of all polyurethane produced in 2016. A polyurethane is typically produced by reacting an isocyanate with a polyol. Since a polyurethane contains two types of monomers, which polymerize one after the other, they are classed as Copolymer#Alternating copolymers, alternating copolymers. Both the isocy ...
