Weldedwire mesh fence is a steel fence consisting of wire strands electrically welded together to form a high strength mesh. The fencing is available in two formats: Rolled mesh and Rigid mesh. Over the last 30 years Rigid Mesh Fencing has become the system of choice for demarcation across the UK, Europe and Australia.
The rigid mesh system has proven popular, and is now featured as a first choice on a wide number of projects from Construction, Civil, Utilities and in a Temporary Works capacity with the likes of Heras Ready Fence and FenceSafe.
Welded wire mesh fences are used predominantly as high security barriers where visibility through the fence is necessary or desirable. It is also used for animal enclosures in zoos.
A zoo is a facility in which all animals are housed within enclosures, displayed to the public, and in which they may also breed.
The longest stretch of Rigid Mesh Fencing in the UK is on the Norton Bridge Flyover, with a continuous fence of 5.5 km.
Powder coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in coating and is then cured under heat to allow it to flow and form a "skin". The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, such as household appliances, aluminium extrusions, drum hardware and automobile and bicycle parts. Newer technologies allow other materials, such as MDF, to be powder coated using different methods. The powder coating process was invented around 1945 by Daniel Gustin US Patent 2538562.
Galvanization or galvanizing is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are submerged in a bath of molten zinc.
In metallurgy, stainless steel, also known as inox steel or inox from French inoxydable (inoxidizable), is a steel alloy, with a minimum of 10.5% chromium content by mass and a maximum of 1.2% carbon by mass.
The Union Buildings form the official seat of the South African Government and also house the offices of the President of South Africa. The imposing buildings are located in Pretoria, atop Meintjieskop at the northern end of Arcadia, close to historic Church Square and the Voortrekker Monument. The large gardens of the Buildings are nestled between Government Avenue, Vermeulen Street East, Church Street, the R104 and Blackwood Street. Fairview Avenue is a closed road where only officials can enter to the Union Buildings. Though not in the centre of Pretoria, the Union Buildings occupy the highest point of Pretoria, and constitute a South African national heritage site.
Pretoria is a city in the northern part of Gauteng province in South Africa. It straddles the Apies River and has spread eastwards into the foothills of the Magaliesberg mountains. It is one of the country's three capital cities, serving as the seat of the administrative branch of government, and of foreign embassies to South Africa. Pretoria has a reputation for being an academic city with three universities, the Council for Scientific and Industrial Research (CSIR) and the Human Sciences Research Council. The city also hosts the National Research Foundation and the South African Bureau of Standards making the city a hub for research. Pretoria is the central part of the Tshwane Metropolitan Municipality which was formed by the amalgamation of several former local authorities including Centurion and Soshanguve. There have been proposals to change the name of Pretoria itself to Tshwane, and the proposed name change has caused some public controversy.
A fence is a structure that encloses an area, typically outdoors, and is usually constructed from posts that are connected by boards, wire, rails or netting. A fence differs from a wall in not having a solid foundation along its whole length.
Barbed wire, also known as barb wire, occasionally corrupted as bobbed wire or bob wire, is a type of steel fencing wire constructed with sharp edges or points arranged at intervals along the strands. It is used to construct inexpensive fences and is used atop walls surrounding secured property. It is also a major feature of the fortifications in trench warfare.
Barbed tape or razor wire is a mesh of metal strips with sharp edges whose purpose is to prevent passage by humans. The term "razor wire", through long usage, has generally been used to describe barbed tape products. Razor wire is much sharper than the standard barbed wire; it is named after its appearance, but is not razor sharp. The points are very sharp and made to rip and snag clothing and flesh.
In agriculture, fences are used to keep animals in or out of an area. They can be made from a wide variety of materials, depending on terrain, location and animals to be confined. Most agricultural fencing averages about 4 feet (1.2 m) high, and in some places, the height and construction of fences designed to hold livestock is mandated by law.
In architecture and structural engineering, a space frame or space structure is a rigid, lightweight, truss-like structure constructed from interlocking struts in a geometric pattern. Space frames can be used to span large areas with few interior supports. Like the truss, a space frame is strong because of the inherent rigidity of the triangle; flexing loads are transmitted as tension and compression loads along the length of each strut. Steel space frames provide great freedom of expression and composition as well as the possibility to evenly distribute loads along each rod and external constraints. With these features, steel space frames can be used to achieve also complex geometries with a structural weight lower than any other solution. The inner highly hyper-static system provides an increased resistance to damages caused by fire, explosions, shocks and earthquakes. Space frames are modular and made of highly industrialized elements designed with a remarkable dimensional accuracy and precise surface finish.
A mesh is a barrier made of connected strands of metal, fiber, or other flexible or ductile materials. A mesh is similar to a web or a net in that it has many attached or woven strands.
An electric fence is a barrier that uses electric shocks to deter animals and people from crossing a boundary. The voltage of the shock may have effects ranging from discomfort to death. Most electric fences are used today for agricultural fencing and other forms of animal control, although they are frequently used to enhance the security of sensitive areas, such as military installations, prisons, and other security sensitive places; places exist where lethal voltages are used.
Shaft mining or shaft sinking is excavating a vertical or near-vertical tunnel from the top down, where there is initially no access to the bottom.
There are many aspects to horse care. Horses, ponies, mules, donkeys and other domesticated equids require attention from humans for optimal health and long life.
A chain-link fence is a type of woven fence usually made from galvanized or LLDPE-coated steel wire. The wires run vertically and are bent into a zig-zag pattern so that each "zig" hooks with the wire immediately on one side and each "zag" with the wire immediately on the other. This forms the characteristic diamond pattern seen in this type of fence.
Temporary fencing, as the name suggests, is a free standing, self-supporting fence panel, the panels are held together with couplers that interlock panels together making it portable and flexible for a wide range of applications. A common type of temporary fencing is Heras fencing. Fence panels are supported with counter-weighted feet, have a wide variety of accessories including gates, handrails, feet and bracing depending on the application. Fence panels are commonly constructed of either chain link or weld mesh.
A steel fence post, also called a T-post, a Y-post, or variants on star post, is a type of fence post or picket. They are made of steel and are sometimes manufactured using durable rail steel. They can be used to support various types of wire or wire mesh. The end view of the post creates an obvious T, Y or other shape. The posts are driven into the ground with a manual or pneumatic post pounder. All along the post, along the spine, there are studs or nubs that prevent the barbed wire or mesh from sliding up or down the post. They are generally designated as 1.01, 1.25 or 1.33, referring to the weight in pounds per lineal foot. They are commonly painted with a white tip on top, white improves the visibility of the fence line.
A swimming pool fence is a type of fence placed around swimming pools, to create a passive barrier to restrict the access of small children, 0–5 years to the swimming pool. Swimming pool fences must have a self-closing and self-latching gate/s to be compliant to most countries' laws and codes.
Mechanical screening, often just called screening, is the practice of taking granulated ore material and separating it into multiple grades by particle size.
Pallet rack is a material handling storage aid system designed to store materials on pallets. Although there are many varieties of pallet racking, all types allow for the storage of palletized materials in horizontal rows with multiple levels. Forklift trucks are usually an integral part of any pallet rack system as they are usually required to place the loaded pallets onto the racks for storage. Since the Second World War, pallet racks have become an essential and ubiquitous element of most modern warehouses, manufacturing facilities, retail centers, and other storage and distribution facilities.
Demarcation of a perimeter, when the protection of assets, personnel or buildings is required, is normally effected by the building of a perimeter fence system. The level of protection offered varies according to the threat level to the perimeter. Different types of perimeter fencing include:
Cable railings or wire rope railings are safety rails that use horizontal or vertical cables in place of spindles, glass and mesh for infill.
Welded wire mesh, or welded wire fabric, or "weldmesh" is an electric fusion welded prefabricated joined grid consisting of a series of parallel longitudinal wires with accurate spacing welded to cross wires at the required spacing.
An aluminum fence is a fence constructed primarily out of the element aluminium. Due to the metal’s low density and ability to resist corrosion, it has become a popular choice as lightweight, durable fence and railing structure.
The SC 50 or cylindrical explosive bomb in English was a family of general purpose bombs used by the Luftwaffe during World War II.
