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

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: How do you use a steel square for marking stair tread and riser dimensions?
- To use a steel square for marking stair tread and riser dimensions, follow these steps: 1. Start by measuring the total rise of the stairs, which is the vertical distance from the top of the landing to the finished floor level. Note down this measurement. 2. Next, determine the desired height of each riser. This can be calculated by dividing the total rise by the number of risers. For example, if the total rise is 48 inches and you want 6 risers, each riser should be 48/6 = 8 inches high. 3. Now, take your steel square and place it on a flat surface. Position the long edge of the square vertically, ensuring it is perpendicular to the surface. 4. Align the bottom corner of the square with the edge of the material you are marking, such as a piece of wood or the stringer on the stairs. 5. With the square held firmly against the material, use a pencil or marking knife to draw a line along the inside edge of the square. 6. For marking the tread dimensions, use the inside edge of the square to measure and mark the desired depth of each tread. The tread depth can be calculated by subtracting the riser height from the desired total run (the horizontal distance covered by the stairs). For instance, if you want a total run of 72 inches and have 6 risers, each tread should be 72/6 = 12 inches deep. 7. Repeat this process for each riser and tread, ensuring that the square remains held firmly against the material to maintain accuracy. Using a steel square for marking stair tread and riser dimensions allows for precise and consistent measurements, resulting in well-balanced and safe stairs. Remember to always double-check your measurements before cutting or installing any materials.

- Q: How does a steel square assist in determining the correct miter angle?
- A steel square assists in determining the correct miter angle by providing a precise tool for measuring and marking angles on wood or other materials. It consists of a long metal blade with a ruler-like scale and a shorter perpendicular blade, forming a right angle. To determine the correct miter angle, you can use the steel square in several ways. One method is by placing the longer blade along the edge of the material you want to cut, and then aligning the shorter blade with the desired angle. The scale on the blade allows you to accurately measure the angle and make adjustments as needed. Once the angle is set, you can mark the material accordingly for cutting. Another way to use a steel square for miter angle determination is by creating a reference line. By aligning the longer blade with one edge of the material and the shorter blade with another edge, you can establish a reference line at the intersection of the two blades. This reference line can then be used to guide the cutting process and ensure the correct miter angle. Overall, a steel square is a versatile tool that allows for precise measurement and marking of angles, making it an essential aid in determining the correct miter angle. Its accuracy and ease of use make it indispensable for carpenters, woodworkers, and anyone else working with angles in construction or DIY projects.
- Q: How do you use a steel square for creating accurate box joints?
