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.
