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: Can steel rebars be used in energy-efficient buildings?
- Certainly! Energy-efficient buildings can indeed incorporate steel rebars. These rebars are commonly utilized in the construction of reinforced concrete structures, including those that prioritize energy efficiency. Energy-efficient buildings aim to decrease energy consumption and minimize their environmental footprint. Although steel is a material with high embodied energy, meaning it requires a substantial amount of energy for production, it boasts numerous advantages for energy-efficient buildings. To begin with, steel rebars lend structural strength to reinforced concrete, enabling the creation of robust and long-lasting structures. This is pivotal for energy-efficient buildings, as their goal is to have an extended lifespan and reduced maintenance requirements, thereby lessening their overall environmental impact. Additionally, steel rebars can be employed in the construction of energy-efficient building components, such as insulated concrete forms (ICFs) and precast concrete panels. These building systems possess exceptional thermal insulation properties, which decrease heat transfer and enhance energy efficiency. Steel rebars are utilized to reinforce these components, ensuring their structural integrity. Furthermore, the thermal mass characteristics of concrete, reinforced by steel rebars, can contribute to a building's energy efficiency. Concrete has the capability to absorb and store heat, aiding in the regulation of indoor temperatures and reducing the need for excessive heating or cooling. Consequently, this can result in significant energy savings throughout a building's lifespan. It is important to note that the energy efficiency of a building is contingent upon various factors, including insulation, window design, HVAC systems, and the integration of renewable energy. While steel rebars play a vital role in reinforced concrete structures, their impact on overall energy efficiency should be evaluated in conjunction with other design choices and building materials.
