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

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:
Steel squares are not inherently rust-resistant. Steel is primarily composed of iron, which is prone to rusting when exposed to moisture and oxygen. However, steel squares can be made rust-resistant through a process called galvanization or by applying protective coatings such as paint or enamel. Galvanization involves coating the steel with a layer of zinc, which acts as a barrier to protect the underlying steel from rusting. These protective measures significantly enhance the rust resistance of steel squares and increase their longevity.
Q:
To use a steel square to measure and mark equal angles, first align one edge of the square with the reference line or surface. Then, rotate the square until the desired angle is achieved, making sure the other edge of the square remains in contact with the reference line. Once the desired angle is set, use a pencil or a scribe to mark the angle on the workpiece. Repeat the process for each angle required, ensuring the square remains aligned and in contact with the reference line.

Q:
To use a steel square to measure and mark 150-degree angles, you can follow these steps: 1. Begin by positioning the steel square on the surface or material where you want to measure the angle. Ensure that one of the edges of the square is aligned with the edge or line that you want to use as a reference. 2. Next, locate the 90-degree angle on the steel square. This is the right angle formed where the two arms of the square meet. 3. From the 90-degree angle, count 60 degrees in a clockwise direction. This can be done by using the markings on the square or by mental estimation, depending on the accuracy required. 4. Once you have reached the 150-degree mark on the steel square, use a pencil or marking tool to make a small mark at the intersection of the 150-degree line and the reference line or edge. 5. To double-check the accuracy of your measurement, you can use a protractor or another measuring tool specifically designed for measuring angles. This will help ensure that the 150-degree angle is correctly marked. Remember to always handle the steel square with care and accuracy while measuring and marking angles.
Q:
To use a steel square to determine the angle of a compound bevel cut, you would place the square against the material, ensuring that one edge is aligned with the surface to be cut. Then, you would adjust the square until the other edge is parallel to the desired bevel angle. By reading the angle measurement on the square, you can determine the angle needed for the compound bevel cut.
Q:
No, a steel square is not typically used for concrete formwork. Concrete formwork requires the use of specialized materials such as plywood, timber, or metal panels that are capable of holding the weight and pressure of the wet concrete. Steel squares are primarily used for measuring and marking angles in carpentry and construction tasks.
