Galvanized steel coil is based on cold-rolled steel strip as substrate, after continuous hot-dip galvanizing process and produced products. This method tightly adheres the coating to the steel with an iron-zinc alloy bonding layer formed by a diffusion process while the heated steel strip is in contact with the molten zinc. It is an excellent resistance to atmospheric corrosion of coated steel. cold-rolled sheet after the zinc can extend the service life for 15-20 years. Galvanised steel coils are successfully used in industries with stringent requirements for corrosion resistance, durability, strength and appearance, and can be formed or have various coatings applied. The key standards to be followed for the production of galvanised coils include EN 10346 (Europe), ASTM A653 / A653M (US). Manufacturers also have their own original standards. Hdg coil classification, product range and properties Standards applied in different countries to set the requirements for hot dipped galvanized steel coils specify steel grade and size ranges for these products. Hot dipped galvanised coils are classified based on the following features: Application of coated steel (profiling, cold forming, manufacture of steel structures) Chemical composition of coating material (pure zinc, zinc-iron/zinc- aluminium/aluminium-zinc/zinc-m , agnesium alloys, etc) Thickness/weight of protective coating ►HDG coils according to European standards Galvanised steel coils as per the European EN 10346, can be coated with zinc, zinc-iron alloy, zinc-aluminium alloy, aluminium-zinc alloy or aluminium- silicon alloy: Zinc coating (Z) is achieved by dipping the prepared strip into a bath with molten alloy, containing at least 99% zinc. This is the most common and traditional way of protecting rolled steel from corrosion. Zinc-iron coating (ZF) is formed by dipping a strip into a bath of molten zinc (at least 99% zinc) with further annealing to form a zinc-iron coating with an Fe content of 8-12%. Such coating is stronger than the traditional zinc coating and has better adhesion with substrate steel due to mutual diffusion between the iron and zinc in the surface layers. That is why this coating is less exposed to lamination or pitting under impact, mechanical stresses or deformation of treated products. Zinc-aluminium coating (ZA) is applied to rolled steel by dipping it into a bath of zinc and about 5% aluminium with a minor content of mishmetal (mix of metals). Rolled steel with such coating has better formability and corrosion protection properties compared with zinc-coated steel. Aluminium-zinc coating (AZ) is applied by dipping steel into a bath of molten metal consisting of 55% aluminium and 1. 6% silicon (with the remaining being taken up by zinc). The combined action of these metals ensures the best corrosion protection compared with other coatings. Aluminium-silicon coating (AS) is created by dipping steel into a bath of molten metal containing aluminium and 8-11% silicon. Galvanized steel coil with such coating is highly resistant to oxidation at high temperature (up to 650°C) and highly resistant to chemical corrosion. Galvanised steel coils manufactured according to the EN 10346 can be made from the following steels: Low-carbon steel for cold forming (DX51D – DX57D). These products are classified based on suitability for cold forming: DX51D – bending and profiling quality; DX52D – drawing quality; DX53D – deep-drawing quality; DX54D – special deep-drawing quality; DX55D – special deep-drawing quality (only +AS); DX56D – extra deep drawing quality; DX57D – super deep drawing quality. Steel for construction and framing (S220GD – S550GD). Rolled products are arranged in increasing yield stress (Rp0. 2), which is indicated in the marking. Rolled products of S220GD – S550GD steel are mainly used in the manufacture of formed sections (Z-, C-, sigma-, U-shaped profiles, etc) for light-gauge steel structures. Steel with high yield strength for cold forming (HX160YD, HX180YD, HX180BD, HX220YD, HX300LAD, etc). Such rolled products are arranged in increasing yield stress (Rp0. 2), which is indicated in the marking. The marking also contains the following information: H – high-strength flat rolled products for cold forming; Х – as-rolled condition (hot-rolled or cold-rolled) is not defined; D – designed for hot-dip coating; B – heat-treated steel; Y – steel with higher formability; LA – low-alloy / micro-alloy steel. Cold-formable multi-phase steel (HDT450F, HCT490X, HDT590X, HCT780X, HCT980X, HCT780T, HDT580X, etc). Rolled products are arranged in increasing minimum tensile strength (Rm0. 2), which is indicated in the marking. The marking also contains the following information: H – high-strength flat-rolled products for cold forming; С – cold-rolled products; D – hot-rolled products; Т (nnn) – the minimum tensile strength in MPa. The last symbol: F – ferrite-bainite, Х – dual-phase; Т – TRIP, С – complex-phase; М – martensite. Galvanised coils as per the EN 10346 standard can be coated with zinc, zinc- iron alloy, zinc-aluminium alloy, aluminium-zinc alloy or aluminium-silicon alloy. The coating weight is expressed as grams per square metre and characterises the weight of the coating deposited on the both strip surfaces. The coating type (Z, ZF, ZA, AZ, AS) and nominal weight are indicated in the coating designation. Depending on the type of protective layer, the minimum weight of coating on both surfaces of a galvanized product can be 100-600 g/m2 (average value for three spots). https://www.jinbosteel.com/

Galvanized steel flat sheet is cut from galvanized steel coil, the base material is cold rolled steel, it has good processing performance. The zinc layer has uniform thickness, strong adhesion, no peeling during processing, and good corrosion resistance.

Galvanised steel sheets are in high demand in industries with stringent requirements for corrosion resistance, durability, strength, appearance and possibility of forming, stamping and applying various additional coatings. The key standards for the production of galvanised sheets include EN 10346 (Europe), ASTM A653/A653M (US).Original manufacturer's standards and regulations should be expressly highlighted. Classification The standards applied in different countries to set requirements for galvanised steel specify the range of steel grades and sizes. The key classification criteria of galvanized steel coil sheets include: Application of galvanised steel (forming, cold forming and manufacture of steel structures) Chemical composition of coating material (pure zinc or zinc-iron/zinc- aluminium/aluminium-zinc/zinc-m , agnesium alloys, etc) Thickness/weight of protective zinc layer

CNC Lathe Truss Robot Truss robot is a kind of full-automatic industrial equipment based on right angle X, Y and Z coordinate system to adjust the working position of the workpiece or realize the trajectory movement of the workpiece. Its control core is realized by industrial controllers (such as PLC, motion control, single chip microcomputer, etc.). Through the analysis and processing of various input (various sensors, buttons, etc.) signals by the controller, after making certain logical judgment, the controller issues execution commands to each output element (relay, motor driver, indicator light, etc.) to complete the joint movement between the X, Y and Z axes, so as to realize a complete set of fully automatic operation process.
