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.
Q5: Can stainless steel rust?
A5: 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: What are the surface finishing techniques for steel strips?
- There are several surface finishing techniques that can be employed for steel strips, depending on the desired final product and its specific requirements. Some of the commonly used surface finishing techniques for steel strips include: 1. Pickling: This technique involves the use of an acid solution to remove any oxide scale or impurities from the steel strip's surface. Pickling helps in improving the strip's corrosion resistance and prepares it for further processing. 2. Electroplating: It is a process wherein a thin layer of metal is deposited onto the steel strip's surface using an electrolytic bath. Electroplating can enhance the appearance of the strip, improve corrosion resistance, and provide additional properties such as increased hardness or conductivity. 3. Galvanizing: This technique involves coating the steel strip with a layer of zinc to provide protection against corrosion. Galvanizing is commonly used in applications where the steel strip will be exposed to harsh environments. 4.

- Q: How are steel strips coated with paint or powder?
- Steel strips can be coated with paint or powder through a process called coil coating, where the strip is unwound from a coil and passed through a series of cleaning, pretreatment, and coating stations. In the case of paint, the strip is first cleaned and treated to ensure proper adhesion, then the paint is applied using rollers, brushes, or sprayers. For powder coating, the strip is electrostatically charged and the powder is sprayed onto the surface, then cured in an oven to create a durable coating.
- Q: How are steel strips processed for soundproofing?
- There are several ways to process steel strips for soundproofing. One method involves applying a layer of sound-absorbing material, like foam or rubber, to the strip. This material helps to reduce noise transmission by dampening and absorbing sound vibrations. The steel strip is typically coated or bonded with the sound-absorbing material to ensure a secure attachment. Another approach is to use a technique called constrained layer damping (CLD), which involves applying a viscoelastic layer to the steel strip. This layer converts sound energy into heat, effectively dissipating vibrations and reducing noise. Materials like butyl rubber are commonly used for the viscoelastic layer because of their excellent damping properties. In addition, surface treatments can be applied to the steel strips to enhance their soundproofing capabilities. For example, perforations or microperforations can be made on the surface to disrupt sound waves and reduce their transmission. This technique is often used in architectural applications, like soundproofing ceilings or walls. Furthermore, the shape and dimensions of the steel strips can also contribute to soundproofing. Using thicker and wider strips increases their mass, which helps to block sound transmission. Additionally, the design of the strips can incorporate features such as corrugations or ridges, which disrupt sound waves. Overall, the processing of steel strips for soundproofing involves various techniques, including adding sound-absorbing materials, applying viscoelastic layers, surface treatments, and optimizing the shape and dimensions. These methods aim to minimize noise transmission and create a quieter environment.
- Q: How are steel strips processed for notching?
- Steel strips are processed for notching by using specialized machinery that cuts V-shaped notches into the strips. This process involves feeding the steel strips through the machine, where a cutting tool applies pressure to create precise notches according to the desired specifications.
