3. Marks:
Color marking: There will be color marking on both end of the bundle for the cargo delivered by bulk vessel. That makes it easily to distinguish at the destination port.
Tag mark: there will be tag mark tied up on the bundles. The information usually including supplier logo and name, product name, made inChina, shipping marks and other information request by the customer.
4. Transportation: the goods are delivered by truck from mill to loading port, the maximum quantity can be loaded is around 40MTs by each truck. If the order quantity cannot reach the full truck loaded, the transportation cost per ton will be little higher than full load.
5. Delivered by container or bulk vessel
Production flow of Stainless Q235/275 Alloyed Mild Steel Flat Bar with High Quality
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.

Q3: How soon can we receive the product after purchase?
A3: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.
Q4: What makes stainless steel stainless?
A4: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.
- Q:Is the laying of a 40X4 flat steel for fire fighting metal trunking?
- Without laying, the cable bridge, each section of the joint, there is a copper wire to prepare flat belt connected, it is bridge grounding jumper cable.
- Q:Are steel flat bars suitable for welding or soldering?
- Yes, steel flat bars are suitable for welding as they can be easily joined together using various welding techniques such as MIG, TIG, or arc welding. However, steel flat bars are not suitable for soldering as soldering is a process that requires the use of a lower temperature and a different type of filler material.
- Q:What are the different types of surface defects in stainless steel flat bars?
- There are various types of surface defects that can be found in stainless steel flat bars, which can be categorized into several groups. Some common surface defects in stainless steel flat bars include the following: 1. Pitting: Pitting refers to the formation of small, localized corrosion spots on the surface of stainless steel flat bars. These spots appear as small holes or pits and are usually caused by exposure to aggressive environments such as solutions containing chloride or acidic substances. 2. Scaling: Scaling occurs when oxide layers form on the surface of stainless steel flat bars due to exposure to high temperatures. This results in a flaky or powdery deposit and can happen during processes like heat treatment or welding. 3. Corrosion: Corrosion is the gradual deterioration of the stainless steel surface due to chemical reactions with the environment. It can take various forms, including uniform corrosion, crevice corrosion, or stress corrosion cracking, depending on the specific conditions and environment. 4. Scratches: Scratches are physical marks on the surface of stainless steel flat bars caused by abrasive contact or mechanical damage. They can vary in depth and severity, and if not addressed properly, they can create localized areas of stress concentration and potential sites for further corrosion. 5. Roll marks: Roll marks are imperfections on the surface of stainless steel flat bars that occur during the manufacturing process. They appear as irregular patterns or lines on the surface and are typically caused by the rolling or finishing equipment used in production. 6. Discoloration: Discoloration refers to changes in the appearance or color of the stainless steel flat bar surface. It can be caused by exposure to high temperatures, chemical reactions, or improper cleaning methods. Discoloration can manifest as light or dark patches, streaks, or a rainbow-like effect known as "heat tint" in cases of overheating during welding. It is important to emphasize that surface defects in stainless steel flat bars not only affect their visual appeal but also compromise their corrosion resistance, mechanical properties, and overall performance. Therefore, it is vital to promptly identify, assess, and address any surface defects to ensure the longevity and reliability of stainless steel flat bars.
- Q:What is the typical price range for steel flat bars?
- The typical price range for steel flat bars can vary depending on factors such as size, thickness, and the current market conditions. However, as a general guideline, the price range for steel flat bars can range from around $10 to $50 per foot.
- Q:Can steel flat bars be easily machined or drilled?
- Steel flat bars can indeed be easily machined or drilled. Steel is known for its excellent machinability, which means it can be easily shaped, cut, or drilled using various tools and techniques. Steel flat bars, being flat and uniform in shape, are particularly suitable for machining and drilling operations. They can be easily worked on using drills, milling machines, lathes, or any other equipment commonly used for metalworking. However, it is important to select appropriate cutting tools and speeds based on the specific grade and hardness of the steel being machined. Additionally, using appropriate coolant or lubrication during the machining process can help prolong tool life and improve the quality of the finished product.
- Q:How do steel flat bars perform in high-pressure applications?
- Steel flat bars perform well in high-pressure applications due to their strength and durability. They can withstand the pressure exerted on them without deforming or breaking, making them suitable for use in various industries such as construction, manufacturing, and oil and gas. Additionally, steel flat bars have excellent corrosion resistance, ensuring their performance even in harsh environments.
- Q:Are steel flat bars suitable for fabrication of machinery parts?
- Steel flat bars are a suitable choice for fabricating machinery parts. Steel, a robust and enduring material, is commonly employed in the manufacturing and construction sectors. Steel flat bars offer stability and support, which makes them ideal for crafting various machinery components. They can be easily customized through cutting, welding, and shaping to meet specific design requirements. Moreover, steel flat bars possess exceptional mechanical properties, including high tensile strength and good ductility, ensuring the durability and dependability of machinery parts. Overall, due to their strength, versatility, and ability to withstand heavy loads and harsh environments, steel flat bars are a favored option for fabricating machinery parts.
- Q:Are steel flat bars resistant to chemical corrosion?
- Yes, steel flat bars are generally resistant to chemical corrosion due to their composition and protective surface finishes.
- Q:Earthing flat steel, width, overlap face, bolt, big country net
- Now it's basically 12mm open holes. Coupled with the expansion screw directly fixed on the wall of the backward technology, electricity and telecommunications has been the traditional practice.
- Q:Can steel flat bars be used for making brackets or supports for HVAC systems?
- Yes, steel flat bars can be used for making brackets or supports for HVAC systems. Steel flat bars are known for their strength and durability, which makes them suitable for providing sturdy support and stability to HVAC components.
