Product Specifications:

Galvanized Channel Steel
1. Professional factory
2. Size: 50MM-400MM
3. Standard: GB,JIS,ASTM
4. Materials: Q235,SS400,A36..

 

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:

Galvanized Steel ChannelGalvanized U channel steel

 

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.

 

FAQ:

Q1: How do we guarantee the quality of our products?

A1: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.

Q2: Can stainless steel rust?

A2: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

Q:The working principle of steel punching machine
Imported PLC control system, industrial color LCD touch screen AC servo motor and driver, imported linear guide rail and fine ball screw, universal ball or brush board, work table and other high-end configuration;
Q:Round and square steel which is strong
From the round and square steel specifications and appearance quality of the steel, 1. force large contact surface and relatively small pressure, 2. and three provide support force and the force behind. The force contact surface of round steel is very strong.
Q:Hot dip galvanized steel can be welded
Hot galvanized square tubes can be welded.Hot galvanized pipe, welding needs to be polished galvanized layer, thoroughly remove zinc coating and oil, dust and other debris, exposing the tube itself metal color, and then welding.Zinc melting point of 419.53 degrees Celsius, low melting point, Zinc Oxide Zinc Oxide formed layer of hot combustion in high temperature welding thousands of degrees Celsius in the combustion of white smoke barrier zinc combustion, influence the flow of the weld pool of liquid metal, destruction of welding arc stiffness, the porosity, slag, weld crack.
Q:TIG welding of stainless steel plate and steel, how to regulate the argon arc welding
Argon arc welding is a kind of welding technology using argon gas as protective gas. Also called argon gas shielded welding. That is, argon shielded gas is applied around the arc welding, and the air is separated from the welding zone to prevent the oxidation of the welding zone. Argon arc welding technology is based on the principle of arc welding on using argon protection for metal welding, the welding material in high current to be welded on the substrate is melted into liquid form of molten pool, the metal to be welded and welding welding technology to achieve a metallurgical combination, due to the high temperature melting on argon welding continuous feeding in the welding material can not contact with oxygen in the air, thereby preventing the material oxidation, therefore can welding stainless steel, iron metal hardware.
Q:It can be used as the steel electrical equipment grounding
The steel can be used as grounding of electrical equipment, but because of the steel and the earth contact surface is relatively small, the grounding efficiency is not high, generally do not use. The steel pipe, angle steel and flat steel and other materials, the ratio of the circumference and area, has a larger contact area with the earth, in the same material case, get smaller grounding resistance, or in the same requirements of the grounding resistance, supplies are more economical than small, square steel.
Q:What is the cold drawn steel material? Why did it break?
20 steel 45 steel Q235B a little more material, no annealing treatment
Q:The difference between the steel chrome and paint
General steel can paint and painting the door company most paint steel, but you must ask whether to do heat treatment, because the paint is paint backward Hongfang heating paint drying process.
Q:How to combine the paint and galvanized steel
No, as long as you choose the special galvanized steel pipe paint, mcGZ type is ok!
Q:How the two square welded T shape angle and turning angle, how to improve the speed and quality?
You can't weld well without using tools, and it can't be welded with high quality. If the site is large and batch welded, you can use wood as a standard corner frame (quite a template). ), if the amount is small, you can buy a wooden triangle plate, steel square to live, post welding,
Q:The difference between staircase truss square steel tube and angle steel
Square steel tube and steel materials are the same, the shape is not the same, the steel is generally square, as the basic structure of escalator truss, angle is generally 90 degrees or other special angle as connections;
