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: What makes stainless steel stainless?

A2: 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:How do you prevent steel angles from warping?: There are several measures you can take to prevent steel angles from warping: 1. Proper storage: Ensure that steel angles are stored in a dry and controlled environment to avoid exposure to moisture. Moisture can lead to rust and warping of the angles. Use pallets or racks to store them horizontally to minimize any bending stress. 2. Controlled cooling: During the fabrication process, it is important to have controlled cooling to prevent rapid temperature changes that can induce warping. Gradual cooling methods, such as air cooling or controlled cooling baths, can help avoid thermal stresses and minimize warping. 3. Minimize heat input during welding: When welding steel angles, excessive heat input can cause localized thermal expansion and contraction, leading to warping. Use proper welding techniques, such as shorter welding times, smaller weld beads, and intermittent welding, to minimize heat input and control the temperature gradient. 4. Preheating and post-welding stress relief: For thicker or high-strength steel angles, preheating them before welding can help reduce the risk of warping. Additionally, performing post-welding stress relief heat treatments can help relieve any residual stresses within the material and prevent warping. 5. Proper handling and transportation: When transporting steel angles, ensure that they are adequately supported and secured to avoid any bending or flexing during transit. Avoid dropping or mishandling the angles, as this can introduce structural deformations that lead to warping. By implementing these preventive measures, you can minimize the risk of steel angles warping and ensure their structural integrity for various applications.

Q:What are the different methods of surface protection for steel angles?: There are several different methods of surface protection for steel angles, each with its own advantages and disadvantages. 1. Painting: One of the most common methods of surface protection is painting. This involves applying a layer of paint to the steel angle to create a barrier between the steel and the surrounding environment. Paint can provide both aesthetics and protection against corrosion. However, it may require regular maintenance and can be prone to chipping or peeling over time. 2. Galvanization: Galvanization is a process where a layer of zinc is applied to the surface of the steel angle. This creates a protective barrier that helps prevent corrosion. Galvanization can be done through either hot-dip galvanizing or electro-galvanizing. Hot-dip galvanizing involves immersing the steel angle in a bath of molten zinc, while electro-galvanizing uses an electrical current to deposit zinc onto the surface. Galvanized steel angles are highly resistant to rust and can provide long-lasting protection. 3. Powder coating: Powder coating is a dry finishing process where a fine powder is electrostatically applied to the surface of the steel angle. The powder is then cured under heat to form a hard, durable coating. Powder coating provides excellent protection against corrosion, impacts, UV rays, and chemicals. It also offers a wide range of color options and a smooth, attractive finish. However, it can be more expensive than other methods and requires specialized equipment for application. 4. Epoxy coating: Epoxy coatings are a type of protective finish made from epoxy resins. These coatings are highly resistant to chemicals, impacts, and abrasions. They provide a tough, glossy finish that can withstand harsh environments. Epoxy coatings are typically applied through a two-part system, where a resin and a hardener are mixed together before being applied to the steel angle. While epoxy coatings provide excellent protection, they can be more expensive and time-consuming to apply. 5. Metal plating: Metal plating involves covering the steel angle with a layer of metal such as chrome, nickel, or zinc. This provides a decorative finish as well as protection against corrosion. Metal plating can be done through electroplating or electroless plating processes. Electroplating uses an electrical current to deposit a thin metal layer onto the surface, while electroless plating does not require electricity and utilizes a chemical reaction to achieve the plating. Metal plating can enhance the appearance and durability of steel angles, but it may not be as effective in highly corrosive environments.
