Pure zinc layer is a plastic zinc layer in hot-dip galvanizing. Its properties are basically close to pure zinc and have ductility so it is flexible. Galvanized pipe is widely used in architecture. This product must have been seen by everyone. However， there are many types of it. When you buy it， you should also find out which one you need. The reason why it is favored by everyone in the market is inseparable from its advantages. Next， Xiaobian will lead you to see the advantages of galvanized pipe.
3 Whether the mesh size and wire diameter of electric welding mesh meet the standards

The alloy carbide formed has strong stability at high temperature.
Generally， what are the customers requirements and standards during acceptance? When the galvanized pipe is accepted， you can judge whether it is qualified from the appearance， or whether there are problems such as missing plating or bubbles on the outer wall of the whole square pipe. Only by solving these problems in time can it be judged as qualified and better used.

The two ends of the steel produced by the seamless pipe manufacturer shall be cut into right angles， and the burrs on the surface shall be removed， which is the raw material used by the seamless pipe manufacturer. The embryo prototube embryo needs to be cut by a cutting machine to form an embryo material with a length of about one meter， which is sent to the furnace for heating through the conveyor belt. The billet is sent to the furnace. After internal heating，Products Show and the fuel used is often ethyne. Temperature control in the furnace is a very key factor.
Stair step plate (stair step plate) is a kind of stair used for platform with steel bar mesh. According to the installation method， it generally has two types: welding fixation and bolt (composition: head and screw). It is directly welded to the keel and does not need the side plate with step plate. It is relatively economical and durable， but it is not easy to disassemble， Thickened side plates are required on both sides of the bolted tread plate， and holes are drilled on the side plates.
yH-section steel belongs to high-efficiency and economic cutting profile (other cold-formed thin-wall section steel， profiled steel plate， etc.). Due to the reasonable section shape， they can make the steel give more play to its performance and improve the cutting capacity. Different from ordinary I-type， the flange of H-section steel is widened and the inner and outer surfaces are usually parallel， so it is convenient to connect with other components with high-strength bolts. Its size composition is reasonable series and models are complete，Products Show which is convenient for setting
GIn the production process， the stainless glittering pipe is affected by the outside and product surface. Due to galvanizing，FrederictonCombien coûte 20 barres d'armature par mètreLe pour et le contre et comment améliorer la qualité the corrosion protection is not corroded. This is the thickness of zinc， and the quality and strength of its coating depend on longevity.
MEnergy costs Because zinc has excellent ductility and its alloy layer is firmly attached to the steel base， hot-plated parts can be formed by cold stamping， wire drawing bending and so on without damaging the coating;
yN Silicon; it can improve the hardness of steel， but the plasticity and toughness decrease. Electrical steel contains a certain amount of silicon， which can improve the soft magnetic properties
According to the historical records of the recent four years， the zinc price in the first quarter was generally higher than that in the whole year， and generally entered a wave of upward trend in the first quarter. However，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd zinc prices continued to decline in the first quarter of ， and showed a trend of accelerating the decline day by day. There are two key reasons for the beginning of this year. First， the vicious change of the real estate industry has led to a rapid decline in the growth rate of Chinas consumption of galvanized pipe and seamless steel pipe， and even a contraction month on month; Secondly， the blind expansion of galvanized pipe factory confused the sense of rhythm of supply and demand balance.
It is also divided into general welded pipe， galvanized welded pipe， oxygen blowing welded pipe， wire sleeve， metric welded pipe， idler pipe， automobile pipe， transformer pipe， electric welding thin-wall pipe， electric welding special-shaped pipe， scaffold pipe and spiral welded pipe.
Pursuit of excellencegGalvanized pipe features:
DThe crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width， the more serious the disadvantages.
Spiral seam submerged arc welded steel pipe for general low-pressure fluid transportation (SY / t- is a submerged arc welded steel pipe for general low-pressure fluid transportation such as water， gas， air and steam， which is made of hot-rolled steel strip coil as pipe blank， often warm spiral forming and double-sided active submerged arc welding or single-sided welding.
bSarah reed warlefieldRecently， the price of zinc has been falling continuously. The key reason lies in the soft skin of galvanized pipe consumption and the slow start of production and marketing rate of manufacturing industries in the middle and lower reaches after the Spring Festival. The disadvantage of zinc price has long been far beyond the level of cyclical factors. The main performance of no prosperity in the hot season is whether the market situation in the off peak season will become a more worried problem in the galvanized pipe sales market.

Filling: welded pipe is welded by electric welding of hot-rolled strip steel， so its influence was not as high as that of seamless steel pipe.
