100% Original Factory Hydraulic Pillar Tube - Carbon structural steel ASTM A36 Q195 Q215 Q235 For building structur – Lu
Introduction High-quality carbon structural steel is referred to as carbon structure steel. Specifically, its carbon content is less than 0.08%. Compared with ordinary carbon steel, its quality is better, it has strict chemical composition and requires to ensure the mechanical performance index, high-quality carbon structural steel with low content of impurities such as phosphorus and sulfur. The types of carbon steel are divided into three categories according to the carbon content: low carb... -
OEM Supply Galvanized U Sections - Flat bar Chinese manufacturer carbon steel galvanized – Lu
Introduction Flat bar refers to a steel with a width of 12-300mm, a thickness of 3-60mm, a rectangular cross-section and slightly dull edges. Flat steel can be a finished steel product, or it can be used as a billet for welded pipes and thin slabs for stacked sheets. Main use: Flat steel can be used as a finished material to make hoop iron, tools and mechanical parts, and used as house frame structural parts and escalators in construction. Flat steel can be produced with fixed thickness, fixe... -
2021 Good Quality Electro Galvanized Sheet - Hot dip galvanized coil Q195 Q235 Q345 manufacturer – Lu
Introduction Hot dip galvanized coil are produced by using hot-rolled steel coils or cold-rolled steel coils as substrates through a continuous hot-dip galvanizing process. According to different annealing methods, hot-dip galvanizing can be divided into two types: in-line annealing and out-of-line annealing, which are also called shielding gas method and flux method respectively.

China wholesale Galvanized Steel Coil - Hot rolled steel coil SS400 Q235 Dip Galvanized Steel Coil – Lu
Introduction Hot-rolled coils are made of slabs (mainly continuous casting billets) as raw materials. After heating, they are made into strip steel by the rough rolling mill and the finishing mill. The hot steel strip from the last rolling mill of finishing rolling is cooled to a set temperature by laminar flow, and then coiled into a steel strip coil by a coiler, and the cooled steel strip coil. Parameter Item Hot rolled steel coil Standard ASTM, DIN, ISO, EN, JIS, GB, etc. Material ... -
OEM/ODM Factory High Speed Wire Rod - Free cutting steel alloy AISI 1212 1117 1215 Mould Steel Tool steel – Lu
Introduction Free-cutting steel refers to an alloy steel in which a certain amount of sulfur, phosphorus, lead, calcium, selenium, tellurium and other free-cutting elements are added to the steel to improve its machinability. With the automation, high speed and precision of cutting, it is very important to require steel to have good machinability. This type of steel is mainly used for processing on automatic cutting machine tools, so it is a special steel. Parameter Item Free cutting steel... -
2021 High quality Hot Dip Galvanized Coil - Hot rolled steel plate Plate manufacturer Q235 Carbon steel plate – Lu
Introduction Using continuous casting slab or blooming slab as raw material, it is heated by a walking heating furnace, high-pressure water is descaled and then enters the rough rolling mill. The rough rolling material is cut head, tail, and then enters the finishing rolling mill for computer-controlled rolling. After the final rolling, it undergoes laminar cooling (computer-controlled cooling rate) and coiled by a coiler to become a straight hair coil. The head and tail of straight hair... -
Factory wholesale Stainless Steel Rectangular Tube - Stainless steel channel High quality grade 201 304 316 Galvanized – Lu
Introduction Stainless steel channel is a long steel with a groove-shaped cross-section. Same as I-beam, stainless steel channel steel is also divided into ordinary channel steel and light channel steel. The model and specification are also expressed in millimeters of waist height (h) × leg width (b) × waist thickness (d). For example, 120×53×5 channel steel, which is 120mm waist height, round steel, need to add a, b, c, etc. to the right of the model to distinguish. Usually, stainless steel ... -
OEM Customized Galvanized Steel Channel - Galvanized I-beam Hot Selling Hot Rolled Supplier – Lu
Introduction The raw material of hot-dip galvanized I-beam is I-beam, so the classification is the same as I-beam. Hot-dip galvanized I-beam is also called hot-dip galvanized I-beam or hot-dip galvanized I-beam. The rust-removed I-beam is immersed in molten zinc at about 500°C to attach a zinc layer to the surface of the I-beam to achieve the purpose of anti-corrosion. It is suitable for various strong acids, alkali mists and other strong corrosive environments. According to the process class... -
Best Price on Spring Steel - Cold heading steel high quality wire plate and bar – Lu
Introduction Cold heading steel is used for forming steel. Cold heading is the use of one or more impact loads at room temperature. It is widely used in the production of standard parts such as screws, pins, and nuts. The cold heading process can save raw materials, reduce costs, and improve the tensile strength and performance of the workpiece through cold work hardening. The steel used for cold heading must have good cold upsetting performance, and the content of impurities such as S and P ... -
