Metal landscape trellis
The metal landscape trellis, also known as a chain link fence, is a style of open metal fencing, used for example to fence parks, golf courses, and industrial premises. The most common type of landscape trellis is made of heavy gauge, interlocked wrought iron wire. Each panel is a rectangle that includes metal links on one or both sides, connected by vertical and horizontal bars. The vertical and horizontal bars are each bent in a U-shape and interlocked.
The metal landscape trellis, a type of barbed wire fence, was patented by Edward K. F. Jahn in 1899 and later manufactured by the A. S. &, W. N. Hoe Company (1901) and the Westinghouse Electric &, Manufacturing Company (1923), in New York. The first recorded sale of landscape trellises was in 1910, in New York, and the fence can still be found there. The original F. W. Woolworth store is surrounded by a metal landscape trellis, and is listed on the National Register of Historic Places.
The fence is a sturdy but light weight, non-poisonous, inexpensive fencing alternative, suitable for many uses. It is also relatively inexpensive to install. It can be quickly made into a high security security fence.
In 1899, Edward K. F. Jahn, who had worked for years as a patent lawyer, designed and patented his "Improvement in fencing wire", which he then called the "metal landscape trellis". The wire was patented in the United States and the United Kingdom. It was initially manufactured and sold by a New York company named Jahn &, Co., which ceased operations in 1902. In 1903, the American Wire and Fence Company (A. S. &, W. N. Hoe Company) was created to manufacture and distribute landscape trellises in the United States. The first U.S. landscape trellises were manufactured by the N.E. Hoe Company of Brooklyn.
By 1915, landscape trellises were used as the primary fence around U.S. and British stores. They were also commonly used for high school gymnasiums, and were common in military training grounds. During the World War I, the U.S. government encouraged the manufacture of landscape trellises by requiring an 8% tariff on imported fencing materials. The product line expanded to include trellises in a variety of other materials including steel, aluminum, wood, wrought iron, and composite. A number of fence companies were formed, including the American Steel and Wire Company, founded in 1921, and the Westinghouse Electric &, Manufacturing Company founded in 1923.
Modern landscape trellises are primarily made of corrosion-resistant metals, including aluminum, galvanized iron, galvanized steel, and stainless steel. Many also use stainless steel, aluminum, and composite for the structure of the posts. They are most often seen around commercial and residential properties, although some are used for agricultural purposes.
Trellises can either be used to enclose the whole garden area or to define a formal border around it, depending on the placement of the trellis and the design of the fence around it. They are used for privacy fencing, to separate adjacent properties, and to add style to the garden. The main purpose is to provide support for climbing or other plants, although some products offer decorative features for added style.
During the Medieval period, the common fence was used to separate fields and cattle, and were often built with stone and mortar. In the Middle Ages, the fencing design and construction was not regulated.
Fence designs and materials were also not standardized during the Medieval and Early Renaissance periods. Fence design was often left up to the local carpenter and master stonemason, or they may have relied on Roman design, which, though not standardised, incorporated some of the basic design concepts such as using stone walls as a frame, mortared rubble and stones for the posts, and wood timbers for the rails.
During the 18th and 19th centuries, fencing styles became more regulated and designed for practical purposes. As the use of wooden fencing increased in the 19th century, and with the development of the agricultural industry, fences came to include agricultural features to protect animals from injury, and to prevent animals from destroying crops or damaging fences.
The development of the fence manufacturing industry in the 20th century also led to some technological advances in fence designs. Fencing posts were developed to resist the extreme weather conditions, and to allow them to be driven into the ground without damaging the surrounding soil. The increased use of composite materials and the application of heat to welded materials made fences easier to build, and stronger. The increased use of plastic fence materials to make fence posts have become more commonly used due to their light weight, ease of manufacture and relatively low price. It is estimated that in the early 21st century, about 20% of fences in the U.S. were made of plastic.
Modern technology has brought numerous advances in fence design and material use. The post and railing material is usually metal, and is usually attached to a wooden top rail. Some metal fence designs incorporate a continuous top rail, while others are made with a continuous or modular rail, and others are made with posts and rails attached with clips.
The post designs have also advanced significantly. In the past, the post design was usually constructed with a concrete base, and wood or metal supports. In the early 20th century, the metal fence post design developed into the hollow post, or pole-post. The metal post design allows for the use of steel, cast iron, and aluminum as materials. The post will usually have a threaded section, which can be used to attach a rail and wire, or a clip that can be attached with cable, string, or zip-ties. The post is usually tapered from a short section at the bottom of the post to a much larger diameter at the top.
The railing, top rail, and bottom rail designs have also been greatly improved with advancements in materials and technology. The top rail and bottom rail are usually made of plastic, plastic composite materials, metal, or wood, although the composite materials are usually not as strong as the other materials. The railing is usually made of plastic or metal. The type of material used in the railing can greatly affect the strength and flexibility of the railing, as well as the overall weight. Some types of materials can be too weak and have frequent breaks in the rail. Other types of material, such as metal, may weigh a lot more than plastic and wood, and have issues with bending and becoming brittle with age. The top and bottom rails are usually placed in a horizontal line around the top and bottom of the post. When the railing is placed in a horizontal line, the rails usually meet and cross over each other. The material used to connect the rails is very important. There are many types of connections, but the most common ones are a metal band and a wooden plank. However, some people connect the rails with cable ties, metal clips, or plastic clips. The material that is used for the top and bottom rails should be the same as that of the rail. Otherwise, a very light rail will slide off the post. The rail design can also help the security of the fence. The wider the rail is, the easier it is for a person to grab the railing. The wider the rails are, the
