PC Strand in Parking Deck Construction

PC Strand is used primarily for prefabricated concrete elements, hollow core slabs, beams, TT-slabs or railway sleepers and in post tensioning constructions such as bridges, or off-shore applications. Prestressed concrete strand is high carbon steel wire that is stranded together and treated to increase strength.

Post-tensioning is a technique for reinforcing concrete. Post-tensioning tendons, which are prestressing steel cables inside plastic duct or sleeves are positioned in the forms before the concrete is placed.

Post-Tensioning Concrete provides a light yet structurally efficient solution for the construction of commercial office buildings, multi-family housing structures and mixed- use facilities. Longer, thinner slabs of post-tensioning concrete require less reinforcing steel to achieve the strength of other construction methods.

Post-tensioned concrete is also used in parking structures. Properly designed post-tensioned parking structures are virtually crack-free and offer aesthetic freedom. Another advantage of post-tensioned of concrete is fire resistance. It is no surprise that owners of hospital, universities, and parking operators choose to use post-tension concrete.  Post-Tensioned concrete is used in millions of parking garages across the US each year.

Common uses of Guy Strand

Guy Strand is commonly used in projects that require a lot of strength and stability. Some of the strongest variations  are used to stabilize the tallest structures in the world. When Guy Strand is used to stabilize a structure, one end is attached to that structure, while the other is anchored to the ground. Guy Strand can be anchored to both hard and solid surfaces. This type of versatility is what make guy strand popular across multiple industries.

Telecommunications

We see Guy Strand used frequently in the telecommunications industry. This is perhaps the most commonly seen use of this product. Telephone and other utility poles are often stabilized with this type of wire. This is possible because guy wire can be manipulated to be extremely resistant to corrosion. A zinc coating is often put on top of guy strand during production to create a barrier between the wire and the elements. We often see guy wire covered with a yellow sleeve. This is to make the strand stand out from a distance.

Cable Railings

Another commonly seen use of guy strand is cable railings. Cable railings are often used in places where one wants an unobstructed view.  Cable railing is used in both residential and commercial products. You often see cable railings in parking decks, balconies, and public walkways. Guy Strand is optimal for this because it is resistant to the elements and can be installed post-construction. The overall cost of maintenance of cable railing is low.

Guy Strand

Generally used to reinforce and add stability to tall structures, guy strand consists of high grade, galvanized steel woven into a 7- wire strand. Guy strand is coated with zinc to protect the wire from corrosion caused from exposure to the elements. Guy Strand is used to add stability to structures in many different industries.

Guy Wire is used in conjunction with utility poles. Utility poles typically have enough strength to stand alone. It is the utility wires attached to the poles that make them unstable. Guy wire is put in place to add balance to the utility pole. Guy wire is often coated with an insulator to ensure dangerous voltages do not reach the ground. Reflective yellow casing is used to make guy wire more noticeable to the public.

The telecommunications industry commonly uses guy strand for cell phone towers. There are 5 different types of cell phone towers.  A guy tower is basically a straight rod supported by wires that attach to the ground as support. Guy towers are the cheapest to construct, especially at heights of 300 ft and beyond. Some guyed towers reach as high as 2,000 ft.

 

 


PC Strand in Stadium Construction

PC Strand is a 7-wire cable made from high carbon steel. It is used in both pre-stressed and post-tensioned concrete construction applications. PC strand is often used in stadium construction. The new Atlanta stadium being constructed in downtown Atlanta will be made of post tensioned concrete slabs.

In July of 2014 a ground breaking ceremony was held for the new stadium. By September of 2014, the first elevated floor slab was framed and poured. These slabs were post tensioned concrete slabs. Post tensioned concrete slabs are pre-stressed steel cables inside sleeves positioned in form then covered with concrete. This same process will be used on each story of the new stadium. This process will ensure that the new stadium is sturdy as well as maintain the strength.

The new stadium is set to open in 2107. The new $1.2 billion multi-purpose stadium will be an iconic sports and entertainment complex.


Solid vs. Stranded Wire

Even with all the various sizes and shapes of wire, and their massive number of applications, it’s possible to break them down into just two basic categories – solid and stranded wires. Solid wires are exactly as they sound: a single, (relatively) thick thread of metal; while the alternative is actually a series of extra-thin wires wrapped together.

Though both styles are equally effective in conducting electricity, they do have some subtle distinctions that make them suitable for different purposes. Learning the differences will help you make the best pick for your specific situation.

Flexibility 

When the need of the hour is flexibility, stranded is the way to go. This loose rope of minute wires is highly flexible, easily bending and wrapping around corners. Extension cords and other long appliance cables are typically made of stranded wire, as Stranded Wirethey’re frequently folded, twisted, and tucked out of the way. For more static applications, where the wire won’t be subjected to repetitive movements, a solid wire is an excellent alternative.

Widths

Stranded wires tend to be larger than solid wires with the same current-carrying capacity (as defined by area of conductive material). This is because stranded wires are composed of rounded wire threads, which do not fit neatly against one another and will thus have small air-filled spaces between them. Solid wire offers a more compact option, if the rigidity is not an issue for you.

Cost

Though this will, naturally, be dependent on a number of factors like width, stranded wire tends to be slightly pricier than solid wire, as additional processing is needed to assemble this wrap of conductive threads. Of course, you should weigh installation costs against maintenance costs – running solid wire is cheaper initially, but in high-motion environments it will not last as long as stranded wire. Careful planning will ensure the most economical selection for your needs.
