gypsum drywall screws

The number of each bundle of the blade barbed rope is 50, which is reduced by hydraulic compression and thus more convenient for loading and unloading. The forklift can load and unload easily. Under normal circumstances, when the export will be packaged and sold, so that the volume occupied in the container is relatively small, it can be easily placed and will not take up much space.

With the development of mining industry, pig iron classification in Our country has been very extensive, to meet the needs of the machinery industry. Generally speaking, iron wire factory produces galvanized iron wire iron can be divided into two categories, is directly from the iron ore through iron tracing exercise out of the metal, the primary components of the ore is iron oxide, silica and other miscellaneous stones. When this ore is specially refined into metal iron, the elements such as carbon, silicon, manganese and so on are mixed in, so that the refined data is called – like general pig iron, also for the initial grade of the material.

We contrast the difference between galvanized electric welding mesh and other electric welding mesh by introducing in detail, and the following describes its material: Galvanized welded wire mesh is made of low carbon wire, through automation of fine precision machinery equipment spot welding processing after forming, selection of disposal of the appearance of zinc leaching technology, produce practice British standard, with smooth surface neat, uniform layout to consolidate, the function is good, even if some sections or accept pressure also won’t attack lax appearances, it is the strongest anti-corrosion function in iron mesh, Screen mesh is iron use one of the most widely network class, excellent anticorrosive makes its popularity in the breeding, sucking the neat surface, increased the look and feel, can play will be decorating effect, this feature makes it reflected in the mining industry, because the select material of low carbon high quality material, make it unique iron mesh not usually have flexibility, Concluded that it in the use of plasticity in the process, and then can be used for hardware technology in the deep processing and production, disorderly wall batch swing, underground leakage prevention crack, light mesh body, so that the cost is much lower than the cost of iron screen, more able to understand its economic and practical. Galvanized electric welding net can be used as poultry cage, egg basket, channel fence, drain sink, porch fence, rat net, mechanical shield, livestock and plant fence, grid frame, etc. It is also widely used in industry, agriculture, construction, transport, mining and other occupations.

Out-of-line annealing means that the recrystallization annealing of hot or cold rolled steel plate is carried out in the bottom type annealing furnace or cover type annealing furnace before entering the hot plating wire line, so that there is no annealing process in the galvanized line. The steel plate must maintain a clean active surface of pure iron, free of oxides and other dirt, before hot dip galvanizing. In this method, the annealed surface oxide sheet is first removed by pickling method, and then coated with a layer of zinc chloride or a mixture of ammonium chloride and zinc chloride solvent for protection, so as to prevent the plate from being oxidized again.
