Welded Wire Mesh Fence
Welded wire 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 a first choice on many types of projects including construction, civil, utilities and temporary works. 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. 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
Powder coating is a type of coating that is applied as a free-flowing, dry Powder (substance), powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then Powder coating#Curing, cured under heat or with ultraviolet light. 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, automobiles, and bicycle frames. Advancements in powder coating technology like UV curable powder coatings allow for other materials such as plastics, composites, Carbon fiber reinforced polymer, carbon fiber, and MDF (medium-density fibreboard) to be powder coated due to the minimum heat and oven dwell time required to process these components. History and general uses The powder coating process was invented around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galvanization
Galvanization or galvanizing ( also spelled galvanisation or galvanising) 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 hot, molten zinc. Protective action The zinc coating, when intact, prevents corrosive substances from reaching the underlying iron. Additional electroplating such as a chromate conversion coating may be applied to provide further surface passivation to the substrate material. History and etymology The earliest known example of galvanized iron was encountered by Europeans on 17th-century Indian armour in the Royal Armouries Museum collection. The term "galvanized" continues to be used metaphorically of any stimulus which results in activity by a person or group of people. In modern usage, the term "galvanizing" has largely come to be associated with zinc coatings, to the exclusion of other metals. Galvanic paint, a p ...

Stainless Steel
Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel's resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen. The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into 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 chemicals and food products. The biological cleanability of stainless steel is superior to both aluminium and copper, having a biological cleanability comparable to glass ...

Union Buildings
The Union Buildings ( af, Uniegebou) 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 through which only officials can enter 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. The Buildings are one of the centres of political life in South Africa; "The Buildings" and "Arcadia" have become metonyms for the South African government. It has become an iconic landmark of Pretoria and South Africa in general, and is one of the most popular tourist attractions in t ...

Pretoria
Pretoria () is South Africa's administrative capital, serving as the seat of the executive branch of government, and as the host to all foreign embassies to South Africa. Pretoria straddles the Apies River and extends eastward into the foothills of the Magaliesberg mountains. It has a reputation as an academic city and center of research, being home to the Tshwane University of Technology (TUT), the University of Pretoria (UP), the University of South Africa (UNISA), the Council for Scientific and Industrial Research (CSIR), and the Human Sciences Research Council. It also hosts the National Research Foundation and the South African Bureau of Standards. Pretoria was one of the host cities of the 2010 FIFA World Cup. Pretoria is the central part of the City of Tshwane Metropolitan Municipality which was formed by the amalgamation of several former local authorities, including Bronkhorstspruit, Centurion, Cullinan, Hammanskraal and Soshanguve. Some have proposed ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
