different types of drywall screws

Wire-wall welding net is widely used in industrial production, agriculture, engineering construction, transportation, mining and other processing and manufacturing industries. Such as machinery and equipment protective cover, animal guardrail, pot flower guardrail, window fence, safety exit guardrail, poultry cage, egg basket and home office food industry basket, paper basket and design decoration. It is suitable for general engineering building wall, pouring concrete, multi-storey building, etc., which plays an important structural role in the thermal insulation system. In the construction of the building, the thermal insulation board of hot-dip galvanized electric welding grid is placed on the inside of the outer mold of the wall to be concreted. The external thermal insulation board and the wall are one kind of live, and the thermal insulation board and the wall are integrated into one body after the removal of the mold. The coating on the surface of the weld core is called the coating. The coating of electrode plays a very important role in the welding process. If the photoelectrode without drug skin is used for welding, in the welding process, oxygen and nitrogen in the air will invade a large number of molten metal, metal iron and beneficial elements such as carbon, silicon, manganese oxidation and nitriding to form various oxides and nitrides, and residual in the weld, resulting in slag inclusion or cracks in the weld. The gas in the weld pool may produce a large number of pores in the weld. These factors can greatly reduce the mechanical properties of the weld and make it brittle.

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.

Nestor rolling cage, high-speed railway Nestor rolling cage and railway Nestor rolling cage are all produced, sold and installed in accordance with the technical requirements of the reference drawing of railway line 2012-8001. Nestor rolling cage is a kind of protective equipment emerging in railway in recent years. Nestor rolling cage is connected by Nestor connecting clip on the longitudinal tensile rib fixed on the bracket. The longitudinal tension and the support are connected with the Φ2.5mm cold-drawn galvanized steel wire around 2 laps and then tightened. The support is set in the column and the middle of the span of the protective fence of 3m. The other spans are only set with the upper column, and the support and the protective fence are connected with the bracket hoop. For the protective fence that has been installed with metal mesh, the Nestor roller cage is directly fixed on the transverse sheet and wire of the metal mesh with the cold-drawn galvanized steel wire of 2.5mm or the Nestor connection fastener.
