FAQ:
Q1: How soon can we receive the product after purchase?
A1: 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.
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.
Q3: Can stainless steel rust?
A3: 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 different methods of cutting steel channels?
- There are several different methods of cutting steel channels, depending on the specific requirements and tools available. Some common methods include: 1. Manual Cutting: This involves using hand tools such as hacksaws, bolt cutters, or shears to cut through the steel channels. This method is suitable for smaller projects or when only a few cuts are needed. 2. Plasma Cutting: Plasma cutting uses a high-velocity jet of ionized gas (plasma) to cut through steel channels. This method is fast, precise, and can be used for both straight and curved cuts. Plasma cutting is typically done with a CNC plasma cutting machine for larger projects. 3. Laser Cutting: Laser cutting uses a high-powered laser beam to melt or vaporize the steel channels, creating a precise cut. This method is efficient, produces clean edges, and is suitable for both thick and thin steel channels. Laser cutting is commonly used in industrial applications. 4. Waterjet Cutting: Waterjet cutting utilizes a high-pressure stream of water mixed with abrasive particles to cut through steel channels. This method is versatile, as it can cut through various thicknesses and materials, including steel. Waterjet cutting is known for its accuracy and ability to create complex shapes. 5. Saw Cutting: Saw cutting is a traditional method that involves using a circular saw or band saw with a blade specifically designed for cutting metal. This method is suitable for straight cuts and can be used for both thin and thick steel channels. 6. Oxy-Fuel Cutting: Oxy-fuel cutting involves using a mixture of fuel gas and oxygen to heat the steel channels to their ignition point, then introducing a high-pressure stream of oxygen to create a cut. This method is primarily used for cutting thicker steel channels and is commonly used in heavy industrial applications. It's important to consider factors such as the required precision, speed, and budget when choosing a cutting method for steel channels.
- Q: Can steel channels be used for creating staircases or handrails?
- Yes, steel channels can be used for creating staircases or handrails. Steel channels provide structural strength and durability, making them suitable for supporting the weight and ensuring the stability of staircases and handrails. Additionally, steel channels can be easily customized and fabricated into various shapes and sizes to meet the specific requirements of the staircase or handrail design.
- Q: What are the different surface treatment processes for steel channels?
- Steel channels can undergo various surface treatment processes to enhance their durability, appearance, and corrosion resistance. Some common methods for treating steel channels include the following: 1. Galvanization: This technique involves immersing the steel channel in molten zinc to create a protective layer that resists corrosion. Galvanization effectively prevents rust formation and extends the lifespan of steel channels. 2. Powder coating: By electrostatically applying a dry powder to the steel channel and then heating it, a durable and smooth coating is formed. Powder coating offers exceptional resistance to corrosion, impact, and UV damage. Additionally, it provides a wide range of color options for aesthetic purposes. 3. Painting: Painting is a popular surface treatment process for steel channels. It entails applying a layer of paint to the surface, which acts as a barrier against moisture and other environmental factors, thereby preventing corrosion. Depending on specific requirements, different types of paints such as epoxy, polyurethane, or acrylic can be used. 4. Anodizing: Although primarily used for aluminum, anodizing can also be applied to steel channels. This process involves immersing the steel channel in an electrolytic bath and passing an electric current through it to create a protective oxide layer. Anodizing improves corrosion resistance and enhances the appearance of steel channels by creating a smooth and decorative finish. 5. Passivation: Passivation is a chemical process that eliminates iron contaminants from the surface of steel channels, enhancing their corrosion resistance. Typically, this process involves treating the steel channel with acid or other chemical agents to remove impurities that could potentially lead to corrosion. These surface treatment processes should be selected based on the specific requirements of the steel channel, including its intended use, environmental conditions, and desired appearance. Each process offers distinct advantages and significantly improves the performance and longevity of steel channels.
- Q: How do you calculate the moment of inertia for steel channels?
