Metal expansion nuts find their usage in diverse fields. In construction, they are frequently employed for securing structural elements, like beams and frames, in concrete. They are also prevalent in HVAC systems, where they help secure ducts and other installations prone to thermal expansion.

1. Load-Bearing Capacity The higher the percentage, the greater the load-bearing capacity of the bolt. This means that 4% anchor bolts can secure heavier fixtures or withstand larger forces compared to 3% bolts.

Steel pipe bracing is a critical element in the field of structural engineering, providing stability and strength to various constructions, from high-rise buildings to bridges. This technique utilizes steel pipes arranged in a specific manner to support and reinforce structures, distributing loads and enhancing resilience against lateral forces such as wind and earthquakes.
