A Hot Dip Galvanized U channel coating is relatively easier and cheaper to specify than an organic paint coating of equivalent corrosion protection performance. The British, European and International standard for Hot Dip Galvanizing is BS EN ISO 1461 which specifies a minimum coating thickness to be applied to steel in relation to the steels section thickness e.g. a steel fabrication with a section size thicker than 6 mm shall have a minimum galvanized coating thickness of 85 µm.
Further performance and design information for galvanizing can be found in BS EN ISO 14713-1 AND BS EN ISO 14713-2. The durability performance of a galvanized coating depends solely on the corrosion rate of the environment in which it is placed. Corrosion rates for different environments can be found in BS EN ISO 14713-1 where typical corrosion rates are given with a description of the environment in which the steel would be used.

Usage of Galvanized Steel Channel:
Applications: Galvanized for outdoor use or exposed evironments. Walkways, Ramps, Structural support
The process of hot-dip galvanizing results in a metallurgical bond between zinc and steel with a series of distinct iron-zinc alloys. The resulting coated steel can be used in much the same way as uncoated.
A typical hot-dip galvanizing line operates as follows:
Steel is cleaned using a caustic solution. This removes oil/grease, dirt, and paint.
The caustic cleaning solution is rinsed off.
The steel is pickled in an acidic solution to remove mill scale.
The pickling solution is rinsed off.
A flux, often zinc ammonium chloride is applied to the steel to inhibit oxidation of the cleaned surface upon exposure to air. The flux is allowed to dry on the steel and aids in the process of the liquid zinc wetting and adhering to the steel.
The steel is dipped into the molten zinc bath and held there until the temperature of the steel equilibrates with that of the bath.
The steel is cooled in a quench tank to reduce its temperature and inhibit undesirable reactions of the newly formed coating with the atmosphere
Package & Delivery of Galvanized Steel Channel:
1.The channel steel will be packed in bundle with steel wire at each end of every bundle and color marking in order to help the customer to recognize his goods more easily at sight.
2. And the channel steel could be loaded into 20ft or 40ft container, or by bulk cargo.If the weight of each bundle reaches more than 3.5 mt, the loading by break bulk cargo should be choosed.When the weight of each bundle reaches less than 3mt, the loading by container should be choosed.
3.As for the transportaion from mill to loading port, the truck will be usually used. And the maximum quantity for each truck is 40mt.
4.All in all, we could do in accordance with customer's request.
- Q:How to distinguish cold formed section steel and hot rolled section steel?
- Cold-formed steel is one of many varieties of steel in the strip width, under normal temperature conditions after the roll, a group of vertical deformation gradually, to meet the requirements of the use of shape and size, then determine the size of the corresponding shear length. This product is cold-formed steel. Of course, it is also possible to obtain cold-formed steel by stamping, bending or drawing. But the roll bending forming method is suitable for industrial production in large quantities. Its product quality, processing cost and production efficiency are incomparable with other methods, and it is the main production process of cold-formed steel. If the equipment is equipped with welding equipment (such as high-frequency welding, argon arc welding, etc.), it can also produce cold rolled steel with closed section.
- Q:What kind of steel is used in steel columns?
- Compared with other steel piles, steel pipe piles have their own advantages in many aspects, such as long joint welding, single pile bearing capacity, bending rigidity and penetration ability.
- Q:What does "BH" mean?
- In accordance with the different smelting quality of steel, steel is divided into ordinary steel and high quality steel. According to the current catalogue of metal products, ordinary steel can be divided into large section steel, medium section steel and small section steel. The section steel can be divided into I-beam, channel steel, angle steel, round steel and so on according to its sectional shape.
- Q:Does the profile include H?
- Another reason is that H steel is made late in our country, so people are used to distinguish it from other shapes. But in the strict sense, H steel is a kind of section bar.
- Q:Elastic modulus of section steel
- Generally speaking, the elastic body exerts an external function, and the elasticity experiences the change of the shape (called strain). The general definition of the elastic modulus is that the stress is divided by the strain. When the material is in the elastic deformation stage, its stress and strain should be changed into a positive proportion (that is to say, according to Hooke's law), and the coefficient of proportionality is called the elastic modulus.
- Q:What are the common types of profiled steel?
- Complex section steel has: I-beam, channel steel, steel, elevator rail, steel sheet pile, and various kinds of agricultural machinery, machinery manufacturing and construction of special-shaped steel.Section steel according to production methods are: hot-rolled steel, cold-formed steel, welding, H steel, etc.
- Q:What is special steel?
- Reinforcing bars for reinforced concreteIs a small type steel reinforced concrete. Including hot rolled round steel bar and prestressed concrete with reinforced concrete, thermal cold rolled steel. Steel reinforcement strip. In addition, also known as the other thread steel. Because the steel in rolling surface of rolled thread handle or reinforcement, steel reinforced concrete is in the construction industry reinforced. According to the material yield point and tensile strength, I, II, III and IV grade steel. The steel bars are used directly. The rebar, reinforced concrete to stress by heat treatment after heat treatment of high strength, but does not apply to steel welding and spot welding, reinforced by 40Si2Mn, 48Si2Mn, 45Si2Cr etc. steel after heat treatment is made, nominal diameter 6, 8.2, 10 mm. Cold rolled ribbed bar with Q215, Q235, 24MnTi steel, nominal diameter 4-12 mm. Steel after heat treatment should be rolled into plate, to heat treatment delivery.
- Q:What does "M" mean?
- M section steel: sectional shape steel like M.
- Q:Can the section steel butt joint in the end?
- Docking is usually available.If welding, it is mainly worried that the welding is not strong and the welding stress is too large. The wall thickness of the section steel is thin, and the butt welding itself is the most unreliable. So, in the joint lining board, fillet welded. Attention is paid to reducing stress in the process.Bolt connection also requires lining plate, pay attention to bolt size, quantity and spacing. To calculate whether thin-walled steel itself will be crushing, the solution is solder paste board, and bolt holes.In short, the principle is that the strength of the butt joint is not weaker than that of other parts, and there is no greater stress.
