Expanding metal wall anchors are designed to hold heavy items by distributing the load across a larger area within the wall. They typically consist of a metal sleeve that expands when a screw is driven into it. This expansion action grips the surrounding material, creating a solid anchor point that can support significant weight. They are particularly useful in scenarios where traditional screws might loosen over time, such as in drywall installation or when hanging items from concrete surfaces.

Overall, metric wedge anchors are a highly versatile and reliable solution for securing heavy loads in concrete. Their ease of installation, strength, and durability make them a popular choice for a wide range of applications. Whether you are building a new structure or repairing an existing one, metric wedge anchors can provide the support you need to complete your project with confidence.

5. Corrosion Resistance Many self-drilling screws are coated or made from stainless steel to resist rust and corrosion. This makes them ideal for outdoor use or in environments where moisture is present.

Steel structures are commonly used in construction due to their durability, strength, and flexibility. One important aspect of steel structures is bracing, which helps to provide stability and resistance against lateral forces such as wind and seismic loads. There are several types of bracing used in steel structures, each with its own advantages and applications.
