    PC Strand , or prestressed concrete steel hair, is a twisted steel cable composed of high-strength steel wires that are stress-relieved (stabilized) for usage in creating prestressed concrete. While there are various types of PC Strand including Bare Strand, Stainless-steel Strand, Epoxy Coated Hair, as well as carbon Fiber Hair.   The Interpretation of PC Wire   Prestress: Artificial compression anxiety to make up for tensile stress and anxiety to be put in from the exterior pressure.   Prestressed Concrete: Concrete Structure built with Pre-Stress.     PC Cable and PC Strand   Steel Wire or Strands used to Pre-stress concrete frameworks. Pre-stressed concrete is high-strength concrete that has interior steel cable reinforcement. Since pre-stressed concrete needs no coverings, it is a low-priced building product.   CP Wire  Types   The prestressed concrete steel wire can be divided According to cable size, s...

The wear resistance and ultra-smooth finish of  tungsten carbide ring gauges  are ideal for demanding manufacturing environments where the use of tool steel may result in premature ring gauge wear. The ring gauge contains a tungsten carbide bushing with a wall thickness of 3 mm to 10 mm, depending on the ring diameter, securely mounted in a knurled steel ring. Tungsten carbide ring gauges are used to check the outside diameter of cylindrical objects and to calibrate  other gauges  or standards, such as calipers, inside micrometers or bore gauges. Why Choose Tungsten Carbide Material? Tungsten carbide is a compound of tungsten and carbon, with the molecular formula WC and molecular weight 195.85. It is a black hexagonal crystal with metallic luster and hardness similar to diamond, and is a good conductor of electricity and heat. Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, but easily soluble in nitric acid-hydrofluoric acid mixture. Pur...

why pick a steel truss The 5 Reasons Why You Should Pick A Steel Truss Whether you ’ re building a skyscraper or just doing a DIY project in your backyard, choosing the right material is critical to getting the job done right. Here ’ s why you should choose a steel truss for your next project. 1. Nothing lasts like a steel truss Put simply, steel lasts a long time. A REALLY long time. In fact, every steel truss that we make is backed by a 50-year manufacturer guarantee. First, steel doesn ’ t weaken with time due to moisture like wood, improving its lifespan. Second, because wood is an organic material, there is always the threat of termite or other organic damage. Nothing eats steel. 2. Extremely strong without taking up much space Steel is far stronger than other  truss materials   like wood, which means less of it supports the same weight. This means that it doesn ’ t take up much space. Walls can the thinner, frames can be smaller, and overall usable square footage goes up...

  Plain steel, also known as carbon steel, is a heavily used metal in the wire mesh industry. Plain steel is popularly manufactured in both woven and welded wire mesh specifications. It is primarily composed of iron and a small amount of carbon. The popularity of the product is due somewhat to its relatively low cost as well as its versatility and widespread use. Plain steel  wire mesh is strong and durable. It is often times dark in color compared to bright aluminum or stainless steel meshes. Steel mesh does not resist corrosion and will rust in most atmospheric conditions. It is because of this, plain steel wire mesh is sometimes used as a disposable item. It is possible to treat  plain steel wire mesh  using a coating treatment which includes galvanizing, PVC, or powder coating. This coating process is often considered an aftermarket treatment. Features & Uses The most popular  uses  of plain steel mesh include: Fireplace screens Small guards Oil str...

With so many different options on the market, it can be tricky to decide which types of metal roofs are best for your home or building. From classic copper to innovative steel, each type of metal roofing material has its own unique advantages. Types of Metal Roofs When you hear the phrase “metal roof,” your thoughts likely go towards a steel roof, but the term encompasses a much larger variety of materials. Depending on your location and environment, the type of material will be a crucial first step in deciding which direction to go. While an aluminum roof is an excellent option for resisting rust in salty, coastal regions, it’s durability factor can be much lower than other materials. Steel, copper, and zinc metal roofing materials also have their own pros and cons. Copper Roofing Considered to be the grandfather of metal roofing, copper roofs have been used for centuries around the world. Copper is an extremely long-lasting metal that in ideal environments, can last well over 200+ ye...

The metal stamping manufacturing process produces strong metal parts and shapes quickly and cleanly. The process uses specialized dies to press sheet metal into the correct shape. Automakers benefit from the use of metal stamping for parts such as fenders and hubcaps because molds can again be used to make parts that are consistent in size and shape to meet tight specifications and tolerances. Some of the key benefits of metal stamping include: Cost-effective: Once molds are made, manufacturers can produce high-volume auto parts at low cost. Metal stamping technology can handle a wide variety of metals, which gives companies a lot of flexibility without increasing costs. Metal stamping dies themselves are also cost-effective to create and maintain good working condition. Finishing steps such as electroplating to produce parts are also cost-effective. Material Efficiency: The  metal stamping  process uses sheet metal to make parts. Sheet metal is efficient and does not add wast...

  One of the key elements to host a delightful event is safety. You should consider two dimensions when it comes to the safety of an event  –  (i) the safety of the crowd that has gathered, and (ii) the safety of the performers on stage. One simple yet very effective tool to achieve this goal is temporary fencing for events, and here is how it is going to be your trump card. 1. Perfect to control the crowd If you are planning a happening event in town, it is going to attract the crow like nectar attracts honey bees. While it definitely elevates the spirit of the event, but the crowd might go crazy when they see their favourite VIP walk past them. So, a temporary fencing is essential during such a situation to help your security team keep the crowd within their limits. 2. A gate crasher ’ s nightmare If you do not want to deal with the nuisance of unwanted audience, then  temporary fencing   id your best friend. An open field event is no big deal for gate crasher...

Cast iron is one of the most extensively used alloys of ferrous. It is made from pig iron by the process of casting and hence the name. Pig iron is placed in the furnace along with other alloying elements and melted until the molten mixture is obtained. The molten mixture is then poured in  casts or molds ​ of required dimension and left to solidify. The resultant solid obtained is the cast iron which finds its use in a myriad of industries. Advantages: 1. Good castability (low Tm, good fluidity) 2. Good machinability (graphite cast irons) 3. Antivibration properties 4. Low-stress concentration 5. Sensibility   Types of cast iron The properties of iron casting can vary according to the alloying elements added. The cast iron’s properties can be manipulated by varying the alloying constituents. The main alloying elements added to the cast iron are carbon and silicon. Based on the amount of the alloying elements added, the cast iron can be classified into grey iron or white ...

  Ranging from yellow, to gray, to traditional red and orange, bricks are found everywhere in many of our cities and are used extensively in construction. In short, the   traditional brick manufacturing process   involves shaping the clay and firing it in an oven to facilitate the creation of solid blocks, perforated blocks, cobogós, tiles and other shapes. Ceramic tiles are inexpensive; easy to find; highly resistant, thermally inert and glossy; and do not require such specialised labour to construct. However, if installed close to a high heat source, ordinary bricks will eventually crack, making   refractory bricks   more suitable. But what does this mean?   What are refractory bricks? A fire brick, firebrick, or refractory is a block of ceramic material used in lining furnaces, kilns, fireboxes, and fireplaces. A refractory brick is built primarily to withstand high temperature, but will also usually have a low thermal conductivity for greater energy eff...
