quality Galvanized Flat Steel & Galvanized Channel Steel factory

Channel steel is divided into ordinary channel steel and lightweight channel steel. The specification of hot-rolled ordinary channel steel is 5-40 #. The hot-rolled flexible channel steel supplied through the agreement between the supply and demand parties has a specification of 6.5-30 #. Channel steel is mainly used in building structures, vehicle manufacturing, other industrial structures, and fixed cabinets. Channel steel is often used in conjunction with I-beams. Channel steel can be divided into four types according to shape: cold-formed equilateral channel steel, cold-formed unequal sided channel steel, cold-formed inner rolled edge channel steel, and cold-formed outer rolled edge channel steel According to the theory of steel structure, it should be the flange plate of the channel steel that is subjected to force, which means that the channel steel should stand upright instead of lying down.

Angle steel can be composed of various load-bearing components according to different structures, and can also be used as connecting pieces between components. It is widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, busbar support installation, as well as warehouse shelves. Angle steel is a carbon structural steel for construction, which is a simple section steel mainly used for metal components and factory frames.

H-shaped steel is mainly used for various civil and industrial building structures; Various large-span industrial plants and modern high-rise buildings, especially in areas with frequent crustal activity and industrial plants under high-temperature working conditions; Large bridges with high load-bearing capacity, good cross-sectional stability, and large spans are required; Heavy equipment; expressway; Ship skeleton; Mine support; Foundation treatment and embankment engineering; Various machine components.

The length of angle steel can be divided into 6 meters, 9 meters, and 12 meters. The normal length of angle steel is as follows: the length of small angle steel is 6 meters, and the specifications of small angle steel are 2.5 # -7 # angle steel; The length of the angle steel in the middle varies from 6 meters to 9 meters, with specifications ranging from 7 # to 12.5 # as representatives; The normal length of large angle steel is 9 meters or 12 meters, and large angle steel refers to angle steel above 14 #; Of course, the specific length can be confirmed with the merchant, and large quantities can also be customized.

  Cold rolled plate 1. The surface of cold-rolled sheet has a certain glossiness, which feels relatively smooth to the touch, similar to the common steel water cup used for drinking water 2. If hot-rolled plates are not pickled, their surfaces are similar to many ordinary steel plates on the market, with rusted surfaces appearing red and non rusted surfaces appearing purple black (oxide scale). The performance advantages of cold-rolled and hot-rolled plates are: (1) Higher precision, the thickness difference of cold-rolled strip steel does not exceed 0.01~0.03mm (2) Thinner size, the thinnest cold-rolled steel strip can be rolled to 0.001mm; Hot rolled plate Hot rolling can now achieve a minimum thickness of 0.78mm. The surface quality is superior, and cold-rolled steel plates can even produce mirror surfaces; The surface of hot-rolled plates has defects such as iron oxide scale and pitting. Hot rolled plates and cold-rolled plates can be customized according to user requirements, and common hot-rolled plate materials include Q235 Q195 SPHC Cold rolling and hot rolling are two different rolling techniques. As the name suggests, cold rolling is the process of making steel at room temperature, which has high hardness. Hot rolling is the process of making steel at high temperatures.

Flat steel refers to steel with a thickness of 12-300mm, 4-60mm, a rectangular cross-section, and slightly blunt edges. Pingda Steel, a flat steel supplier in Foshan, is a manufacturer of hot-rolled flat iron and flat steel strip processing.   Steel is an iron carbon alloy with a carbon content between 0.04% and 2.3%. To ensure its toughness and plasticity, the carbon content generally does not exceed 1.7%. In addition to iron and carbon, the main elements of steel include silicon, manganese, sulfur, phosphorus, and so on.   There are various methods for classifying steel, and the main methods are as follows:   [Classified by Quality] Carbon steel: Low carbon steel (C ≤ 0.25%); Medium carbon steel (C ≥ 0.25-0.60%); High carbon steel (C ≥ 0.60%). [Classified by forming method]: Hot rolled steel/Cold drawn steel. [Classified by metallographic structure]: Normalized state: Pearlite steel; Bainitic steel; Martensitic steel; Austenitic steel.   [Classified by purpose] Ordinary carbon structural steel; Low alloy structural steel; Reinforced steel. Spring steel bearing steel Tool steel: Carbon tool steel; Alloy tool steel; High speed tool steel. Boiler steel, pressure vessel steel, agricultural machinery steel, etc.   [Comprehensive classification] Alloy structural steel; Spring steel; Easy cut steel; Bearing steel; High quality structural steel for specific purposes.
