Factory Supplier Hot Dip Galvanized Round Steel Pipe For Construction
Galvanized pipe is made of molten metal and iron matrix reaction to produce alloy layer, so that the matrix and coating two combination. galvanizing is to first pickling the steel tube. In order to remove the iron oxide on the surface of the steel tube, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Complex physical and chemical reactions occur between the steel tube base and the molten bath to form a compact zinc-iron alloy layer with corrosion resistance. The alloy layer is integrated with the pure zinc layer and the steel tube matrix. Therefore, its corrosion resistance is strong.

Dx51D RAL9003 0.6mm Hot Rolled Prepainted PPGI Color Coated Galvanized Steel Coil For Sale
The product obtained by coating the organic coating on the PPGI is the hot-dip galvanized color coated plate. In addition to the protective effect of zinc, the organic coating on the surface also plays a role in isolating protection and preventing rust, and the service life is longer than that of the hot galvanized sheet. The zinc content of hot-dip galvanized substrate is generally 180g/m2 (double-sided), and the maximum galvanizing amount of hot-dip galvanized substrate for external construction is 275g/m2.

Galvanized Square Steel Tube in Multiple Sizes
Galvanized square pipe refers to a steel pipe coated with a layer of zinc on the surface of ordinary steel pipes. The zinc layer can form a protective film on the surface of the steel pipe, which can effectively extend the service life of the steel pipe and improve the corrosion resistance of the steel pipe.

Astm Standard St37 Hollow Tube Square 2.5 Inch Galvanized Steel Tubing
Galvanized square pipe The molten metal reacts with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot dip galvanizing is to first pickling the steel pipe, in order to remove the iron oxide on the surface of the steel pipe, after pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank for cleaning, and then into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Most of the processes in the north adopt the zinc replenishment process of galvanized belt direct coil pipe.

Factory Wholesale Price Carbon Steel Pipe Square Hollow Section Galvanized Shs Steel Pipe
Galvanized square pipe is electric galvanized, galvanized amount is very small, only 10-50g/m2, its own corrosion resistance is much different than hot galvanized pipe. Regular galvanized pipe manufacturers, in order to ensure quality, most do not use electric galvanizing (cold plating). Only those small enterprises with obsolete equipment use electric galvanizing, of course, their prices are relatively cheap. The Ministry of Construction has formally announced the elimination of cold galvanized pipes with backward technology, and it is not allowed to use cold galvanized pipes as water and gas pipes. The galvanized layer of cold galvanized steel pipe is an electric coating, and the zinc layer is independently layered with the steel pipe matrix. The zinc layer is thin, and the zinc layer is simply attached to the steel tube matrix and easy to fall off. Therefore, its corrosion resistance is poor. In new residential buildings, it is prohibited to use cold galvanized steel pipes as water supply pipes.

Factory Price Galvanized Erw Welded Steel Square Tube
Galvanized square pipe is divided into cold galvanized steel pipe, hot galvanized steel pipe, cold galvanized steel pipe has been banned, the latter is also advocated by the state can be used temporarily. In the 1960s and 1970s, the developed countries in the world began to develop new types of pipes and gradually banned galvanized pipes. China’s Ministry of Construction and other four ministries and commissions have also issued a document to prohibit galvanized pipes as water supply pipes from 2000, the cold water pipes in the new community have rarely used galvanized pipes, and the hot water pipes in some communities use galvanized pipes. Hot-dip galvanized steel pipe has a wide range of applications in fire, power and highway.

High Grade Q345B 200*150mm Carbon Steel Welded Galvanized Steel H Beam for Construction
H – beam steel is a new economic construction. The section shape of H beam is economical and reasonable, and the mechanical properties are good. When rolling, each point on the section extends more evenly and the internal stress is small. Compared with ordinary I-beam, H beam has the advantages of large section modulus, light weight and metal saving, which can reduce the building structure by 30-40%. And because its legs are parallel inside and outside, the leg end is a right Angle, assembly and combination into components, can save welding, riveting work up to 25%.
H section steel is an economic section steel with better mechanical properties, which is optimized and developed from I-section steel. Especially, the section is the same as the letter “H”

High Quality SS400 H Section Galvanized Steel H Shape Beam
H-shaped steel is a kind of economically efficient profile with more optimized section area distribution and more reasonable strength-to-weight ratio, which is named because its section is the same as the English letter “H”. Because all parts of H-shaped steel are arranged at right angles, H-shaped steel has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions, and has been widely used.
