Generally, galvanized wire used for welding is required to have a certain hardness. After acceptance of galvanized wire, the first thing to do is to feel the hand, and the other thing is to test on the machine. Because the average user does not have testing equipment, it is also very inconvenient to test on the machine. Use a micrometer to measure the diameter of galvanized wire evenly, and keep it about 0.02mm above and below the contract signing standard, with neat appearance, no leakage plating and no mess.

Galvanized iron wire has tolerance and elasticity, the amount of zinc can reach 300 g/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Widely used in construction, handicrafts, wire mesh, highway guardrail, commodity packaging and ordinary civilian and other fields.

Strength of galvanized wire: tensile strength is the great tensile stress that the material can withstand before tensile fracture; Yield strength has two indexes: upper yield and lower yield. It is a process in which the stress does not increase but the deformation continues to occur during the tensile process. When the force value drops for the first time, the major stress is the yield strength, and the yield strength must be less than the tensile strength.

Pros And Cons Of Cotton

It was during the Renaissance Period when bedding as we know it today was designed. Whilst the poor continued to sleep on hay-covered platforms, the wealthy owned mattresses stuffed with down and wrapped in luxurious materials. Their four-poster beds were covered in embroidered canopies and contained pull-out trundles for maids and personal valets to sleep on. Mattresses were suspended from the bedframes using ropes or straps. They were covered by smart linen sheets and wool blankets. The beds grew more and more lavish for the most wealthy. They became so expensive they were passed down through the family for generations. Reported to spend most of his day in bed, Louis XIV became so obsessed with bedding that he bought 413 beds for the Palace of Versailles. It is understood that he held court daily from his bed.

Duvet covers are always equipped with a closure mechanism, such as buttons or zippers. Some are available with various ornamental decorations that add elegance and texture to them, such as embroidery, ribbons, or buttons, while others are plain. Duvet covers with pleats, ruching, and flocking are examples of various decorations that may be seen on high-quality bedding. Similarly, pleating is a form of fold that is created by folding fabric over itself while ruching is a procedure created by gathering little ripples in the fabric together. Flocking is the deposit of microscopic particles on the surface of a cloth.
