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:How do you cut a steel flat bar?
- To cut a steel flat bar, you will need the following tools: a metal cutting saw, a clamp or vice to secure the bar, and safety equipment such as gloves and goggles. Here's a step-by-step guide on how to cut a steel flat bar: 1. Measure and mark the desired length of the steel flat bar using a measuring tape and a marker. Make sure the marks are clearly visible. 2. Secure the steel flat bar in a clamp or vice, ensuring that it is tightly held and won't move during the cutting process. This will provide stability and prevent any accidental movements. 3. Put on safety gloves and goggles to protect yourself from any flying metal fragments or sparks. 4. Position the metal cutting saw perpendicular to the steel flat bar, aligning it with the marked cutting line. 5. Start the saw and slowly guide the blade into the steel flat bar, applying steady and even pressure. Let the saw do the cutting work; avoid forcing or pushing too hard, as this can damage the saw blade or cause the steel to overheat. 6. Continue cutting until you reach the marked cutting line. Take breaks periodically to allow the steel to cool down if needed, as excessive heat can affect the cutting process. 7. Once the cut is complete, turn off the saw and inspect the steel flat bar for any rough edges or burrs. Use a metal file or sandpaper to smooth out any imperfections. 8. Finally, remove the steel flat bar from the clamp or vice and clean up the work area, ensuring all metal shavings are properly disposed of.
