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.
The process of creating oil-tempered wire involves first drawing steel down to a specific diameter, before heating to extremely high temperatures and then rapidly cooling it through immersion in oil. This results in an extremely durable wire, with an excellent fatigue life and resistance to relaxation. Compared to music wire, another popular steel option, oil-tempered wire tends to be both cheaper and thicker – though of course it’s available in a variety of widths.
What, then, are the advantages of this process? And what sort of products might require oil-tempered wire? We’ve rounded up a couple of the major ones below:
Garage Door Springs
The strengthening effect of the oil tempering process makes this wire extremely hardy and gives it high-tensile properties. It’s quite a popular material for springs – especially those that see relatively constant loads, in contrast with ones that are heavily stressed and frequently cycled. This makes oil tempered wire a perfect fit for garage door springs, which support considerable forces for longer periods of time, with fairly infrequent movement.
From combustion engine valves to clutches to transmission dampers, the tensile strength and fatigue life of oil-tempered wire allows for springs that satisfy the extreme demands of precision auto parts. Tempering reduces brittleness and ensures more uniform mechanical properties, compared to wires that are simply cold-drawn, meaning that these ultra-important components on which your vehicle’s life (and your safety) depends are extremely resistant to breakage and very slow to wear down.
These small, typically custom-made wire pieces fit a variety of applications, and are integral components to all sorts of commodities. When choosing a material to construct your forms from, oil-tempered wire is a serious contender. Its sturdy, resilient properties make it a great general-purpose material and a reliable part of any end product.
More commonly known as piano wire, music wire has a number of uses beyond the creation of chordophones. Available in a number of thicknesses, this is a hardy and reliable high-tensile steel wire with a heavy carbon content. Since music wire needs to be remarkably strong for its size, in order to handle the constant pulling and vibrations of a piano string, it’s a popular component with a number of other industrial uses. Here are just a few:
Music wire needs to be capable of handing excessive tension and stress in a resilient manner. Even after heavy use, good piano wires will need to maintain their elasticity to preserve sound quality. These very traits make music wire a great raw material for the creation of small springs – for instance, those used in windowpanes or ballpoint pens.
Wire Cheese Slicer
Cheese slicers consist primarily of a cutting surface and a stretched music wire, which can be angled downwards to easily cut uniform slices of varying size off a cheese block or wheel. This is especially useful for softer cheeses, which may compress under the width of a full-fledged knife or other slicing tool.
The shiny look, and tendency to vibrate, of piano wire make it an excellent component in fishing lures. These artificial and reusable tools are great at attracting the attention and interest of fish without the need to handle live bait.
Owing to its flexibility, strength, and ease of shaping, music wire is commonly used in recreational hobbies like model railroading and radio-controlled vehicles, as well as in creative crafting and knitting.
High elastic and moldable music wire is often used in the fabrication of delicate jewelries. The wire-wrapped look of earrings, rings, and bracelets can be quite stunning. Be sure to determine the proper thickness for your needs.
Music wire doesn’t have to be part of your final product – it can also be a means to an end. When used on a lathe or handheld tool, this thin yet resilient wire is fantastic at high-precision shaping of soft woods and other materials.

2014 has been deemed “the tallest year ever.” This is because during 2014 nearly 100 skyscrapers were completed around the world. Three skyscrapers were completed in the United States while China topped the charts with 58 total skyscrapers. The increase in skyscraper construction is good news to the steel industry as most skyscrapers are supported with multiple steel components.
Many of these steel supported infrastructures use pre-stressed concrete. Pre-stressed concrete is uses to increase the strength and extend the life of concrete. Pre-stressed concrete strand is covered and bonded to concrete to create and study slab. This process is ideal in the construction of skyscrapers as they require an abundance of strength and stability.

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.
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.
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.

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.
Oil tempered wire is a cold drawn, heat treated wire. The process of tempering increases the strength and hardness of the wire without making the wire more brittle. Tempering makes oil tempered wire perfect for springs and wire forms.
The springs used in car seats are often oil tempered wire springs. When oil tempered springs are covered with cloth cushioning, it provides plenty of comfort and support. The springs are often coated to avoid noise. This is especially important for infant car seats.
Another use of oil tempered wire in the automotive industry is in the filtration system for air bags. This filtration system is used to filter out dust and smoke in the air bag as well as smother flames during combustion. Oil tempered wire is perfect for this because it can handle the stress and heat pressure.
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.
We’ve all heard the term before, but what exactly is this process? Galvanization is simply the coating of steel (or iron) with a molten zinc covering. This zinc bonds with the steel and protects the underlying material from corrosion – especially rusting – and from light mechanical damages. Galvanization offers some tremendous benefits in the short term and over extended periods –we’ve assembled a quick rundown below:
Low Cost – Both Initially and Over Time
Iron-based products and alloys essentially require protective treatments of some sort, due to their susceptibility to oxidation. Galvanization is a factory process, and one that’s cheaper than most of the other coating options (especially labor-intensive ones, like the application of protective paints). Low upkeep requirements and a long effective life make it cost-effective in the long term as well – especially in remote areas where the cost of providing maintenance is considerably higher.
The zinc coating doesn’t just stick to the exterior of steel or iron – it actually bonds with it, creating a secure and complete protection that penetrates below the surface level. Not only does this protect the vulnerable ferrous material from the rust-inducing elements, it offers an additional layer of metal that rust must work through in the event of any contamination.
Zinc’s electronegativity is greater than that of iron, making it an anode that will corrode in preference to the underlying metal. Essentially, this means that even if the outward zinc layer on galvanized material is chipped or otherwise damaged, the remaining material will still protect the exposed iron/steel by attracting corrosion to itself.
Ease of Inspection
Though the galvanization process is effectual and long-lasting, any coating will inevitably require some maintenance. Fortunately, this process is easy – galvanization produces a characteristic spangle, and a simple visual inspection is very effective in identifying damage to the coating (if it looks intact, it is intact).
