It is a potential rolled strip steel with rectangular section for general purpose. It is very common on construction sites. Its specifications are expressed in thickness and width. At present, most of the flat steel on the market are finished steel,StragaHow much is I-beam per meter, which can be used ready-made for components, ladders, bridges and fences. Flat steel can also be used as blank for welding rigid steel and slab for laminated thin plate. Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason the special rolling method can be used to make full use of the skills of uneven deformation and pass design. For example, when the billet section is narrow and wide I-beam is required to be rolled, the wave rolling method can be used; for example, the negative rolling method can be used Spread rolling, etc.Straga,Packaging: Welding nets are generally packaged in paper (mostly gray white, yellow,StragaWhat is the diameter of 1.5-inch welded pipe, etc.), some similar to welding wire diameter welding nets, agriculture, transportation, mining and other industries. Such as machine shields, animal fences, flower and tree fences window fences, aisle fences, baskets and decorations.Key technical characteristics of alloy pipe:Zouila,The high-temperature passivation treatment of alloy pipe is to obtain the passivation treatment film by heating in the heat treatment equipment. Before passivation treatment, the surface layer of parts must be removed to remove waste. At a higher temperature, the passivation treatment film can be obtained according to the transformation temperature and time. The hue of passivation treatment film can refer to the annealing color of alloy pipe, and the main parameters of ambient temperature and time of heat treatment process can be selected.I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams. The specifications of the first two are -, that is, the corresponding height is -. At the same height, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.It is widely used in various fields of national economic construction, such as buildings, bridges, power stations, oil drilling platforms, highways, subways, steel structure plants and large warehouses

I-beam is divided into ordinary I-beam and light I-beam. The specification of hot rolled ordinary I-beam is -#. The specification of hot-rolled flexible I-beam supplied through agreement between the supplier and the buyer is -#. I-beam is mainly used in building structure, vehicle manufacturing, other industrial structures and fixed panels and cabinets. I-beam is often used together with I-beam. Spiral seam submerged arc welded steel pipe (SY- for pressure fluid transportation is a spiral seam steel pipe used for pressure fluid transportation which takes hot-rolled steel strip coil as pipe blank, often warm spiral forming and welded by double-sided submerged arc welding. The steel pipe has strong pressure bearing capacity and good welding . After various strict scientific inspections and tests,StragaHow much is a 12 cm I-beam, it is safe and reliable to use. The steel pipe has large diameter and high transportation efficiency, and can save the investment in laying pipelines. It is mainly used for transporting oil and natural gas.The shape of small longitudinal crack on the surface of alloy pipe is less than mm The overall width is less than mm The depth is lower than .mm.Where to sell API, Cold extrusion. This kind of processing method is more purposeful. Before the preparation of steel processing and extrusion molding, when the extrusion molding is used for mm diameter pipe fittings, the investment of machinery and equipment is less, so the raw material consumption is also very small, and the technology is relatively perfect. Once the tube size is increased, the cold extrusion method must have large cargo capacity and high-power machinery and equipment. Therefore, the automatic control system will be upgraded.C-section steel has uniform zinc layer, smooth surface, strong adhesion no zinc scar, no zinc leakage and high dimensional accuracy. All surfaces are wrapped by zinc layer, and the zinc content on the surface is usually -g /? It has long service life, corrosion resistance and durability. It is a kind of stronger protection.The finished product has smooth surface, low friction coefficient, flatness error + / - mm / m length, wear resistance and maximum temperature of ℃

Key technical characteristics of alloy pipeproperty right,Stages needing attention in the production and manufacture of alloy tubes East West derusting: if the galvanized pipe surface is rusty, the manufacturer will choose East West derusting and polish it with a steel wire brushAlloy pipes can be used for heating (cooling) projects.Straga, Cold extrusion. This kind of processing method is more purposeful. Before the preparation of steel processing and extrusion molding, when the extrusion molding is used for mm diameter pipe fittings, the investment of machinery and equipment is less, so the raw material consumption is also very small, and the technology is relatively perfect. Once the tube size is increased, the cold extrusion method must have large cargo capacity and high-power machinery and equipment. Therefore, the automatic control system will be upgraded. The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.The shape of small longitudinal crack on the surface of alloy pipe is less than mm The overall width is less than mm The depth is lower than .mm.
