Aluminum foil finishing process
In many applications, aluminum foil is used in combination with other materials. It can be coated with a variety of materials, such as polymers and resins, for decorative, protective or heat-sealing purposes. It can be laminated to paper, cardboard and plastic film. It can also be cut, formed into any shape, printed, embossed, cut into strips, sheeted, etched and anodized. Once the foil is in its final state, it is packed accordingly and shipped to the customer.
How to maintain hot-dip galvanized square pipe?
Regarding the content of hot-dip galvanized square pipes, today the editor of GNEE STEEL will introduce to you how to effectively extend the service life of hot-dip galvanized square pipes? I think this is also an issue that many people are concerned about. In fact, if we want to make the hot-dip
Characteristics and differences of various galvanized square pipes
In terms of production technology, galvanized square tubes are divided into cold-dip galvanized square tubes and cold-dip galvanized square tubes. Precisely because these two galvanized square tubes are almost the same, they have many different physical and chemical properties. Overall, they have many differences in strength, toughness, and mechanical properties. Hot-dip galvanized square tube: It is a square tube made by curling and welding steel plates or steel strips. On this basis, the square tube is placed in a hot-dip galvanizing pool and formed through a series of chemica
Galvanized square pipe price and quality
Usually when everyone buys galvanized square pipes, the first thing they pay attention to is the price of galvanized square pipes. What I want to tell you here is that in addition to price, we should actually pay more attention to the quality of galvanized square pipes and choose Only high-quality products can ensure construction safety. So how to identify fake galvanized square pipes? Below, the editor of GNEE STEEL will
Different processes and methods of hot-dip galvanizing steel
Hot-dip galvanizing of steel can be divided into flux method hot-dip galvanizing and hydrogen reduction method hot-dip galvanizing according to the difference in pretreatment methods. Flux method hot-dip galvanizing is mainly hot-dip galvanizing of steel components, steel pipes, steel profiles, etc.; hydrogen reduction method hot-dip galvanizing Galvanizing is mainly used in continuous hot-dip galvanizing of steel strips, steel wires, etc. Galvanized products generally undergo bending and forming deep processing, and are used indoors and outdoors.
Processing performance characteristics of ZAM Sheet
1. Scratch resistance of coating Planar corrosion of coated plates mostly occurs at scratches, and scratches are an inevitable phenomenon for coated plates, especially during processing. If the coated plate itself has good scratch resistance, it can be used in a long time. Avoid scratches to a large extent, thus extending its service life. Scratch performance is expressed by the load generated by scratches. The measurement method is to move a sapphire test needle with a tip radius of 0.05mm perpendicular to the test site under a load ranging from 0.0196 to 0.196N (2 to 20
High-grade hot-dip galvanized sheet for automobiles
Automotive industry products have high efficiency, high reliability, and high integration requirements. Hot-dip galvanized steel sheets for automobiles are the best and the best among galvanized steel sheets. In the more than 20 years since the United States first applied hot-dip galvanized sheets to the automobile industry in 1975, major automobile production countries in the world have been working hard to develop
Development status of hot-dip galvanizing coating varieties
1) Lead-free hot-dip galvanizing coating Beautiful zinc flowers are a typical feature of traditional hot-dip galvanized sheets, which are favored by users and have certain commercial value. However, studies have shown that the unevenness of the zinc pattern surface and the lead content in the coating will affect the processing performance, coating performance and corrosion resistance of the coated plate in subsequent proce
Do you know about cold rolled plate materials?
Cold-rolled sheets are products made by rolling hot-rolled coils at room temperature below the recrystallization temperature. Most of them are used in automobile manufacturing, electrical products, etc. Properties of cold-rolled plates: Cold-rolled plat
Salesmen in the steel trade circle often purchase or sell SPCC cold-rolled materials, and often use DC01 materials and SPCC as substitutes for each other. Indeed, the two are interchangeable brands in use, but we still need to pay attention to what Woolen cloth? Behind each steel grade, there are mechanical properties, chemical composition and uses of the steel product. Specific letters, numbers and sorting
General knowledge of cold rolled plates
Production Process Since there is no heating during the production process, there are no defects such as pitting and oxide scale that often occur in hot rolling, and the surface quality is good and the finish is high. Moreover, the dimensional accuracy of cold-rolled products is high, and the performance and structure of the products can meet some special usage requirements, such as electromagnetic properties, deep drawing properties, etc. Specifications: The minimum thickness is 0.2-4mm, the width is 600-2 000mm, and the steel plate length is 1 200-6 000mm.

The Difference Between Hot-Dip Galvanized Pipe And Pre-Galvanized Pipe
The process difference between hot dip galvanizing and pre-galvanizing Hot-dip galvanizing involves immersing steel in a pool of molten zinc, and a layer of zinc alloy coating is coated on the surface of the steel through a chemical reaction. Because the steel is exposed to high temperatures, the coating is firmly connected to the steel surface and therefore more resistant to corrosion. Pre-galvanizing is to galvanize the steel first, apply a thin layer
Hot-Dip Galvanized Steel Pipe Wall Thickness Standards
The wall thickness standards of hot-dip galvanized steel pipes vary according to different applications and specifications. Here are some criteria for various situations: General purpose: According to the national standard GB/T3091-2008, the wall thickness of hot-dip galvanized thickened steel pipes ranges from 0.6mm to 20mm. For low-pressure fluid transportation and mechanical structures: also based on GB/T3091-2008, wall thickness range is 0.6m

Advantages and disadvantages of hot rolled seamless steel pipe
The production process of general seamless steel pipes can be divided into two types: cold drawing and hot rolling. Hot rolling, as the name suggests, has high temperature, so the deformation resistance is small, and large deformation can be achieved. Take the rolling of steel plates as an example. Generally, the thickness of continuous casting billet is about 230mm, and after rough rolling and finish rolling, the final thickness is 1~20mm. At the same time, due to the small width-to-thickness ratio of the steel plate, the dimensional accuracy requirements are relatively low, and plate shape p

Seamless steel pipes are widely used. According to different uses, there are thick-walled seamless steel pipes and thin-walled seamless steel pipes. 1. General purpose seamless steel pipes are rolled from ordinary carbon structural steel, low alloy structural steel or alloy structural steel according to the material. For example, seamless pipes made of low carbon steel such as No. 10 and No. 20 are mainly used as transportation pipelines for steam, coal gas, liquefied gas, natural gas, various petroleum products and various other gases or liquids; medium carbon steel such as 45 and 40Cr
API 5L generally refers to the execution standard for pipeline steel pipes. Pipeline steel pipes include seamless steel pipes and welded steel pipes. At present, the commonly used welded steel pipe types on oil pipelines include spiral submerged arc welded pipe (SSAW), straight seam submerged arc welded pipe (LSAW), and electric resistance welded pipe (ERW). Seamless steel pipes are generally selected when the pipe diameter is less than 152mm. Steel grade of API Seamless Steel Pipe The raw material steel grades of API 5L steel pipes include
