Stålbjælker

Stålbjælker, also known as steel beams, are structural components made from steel used in construction to support loads. Their high tensile strength and ability to span long distances make them indispensable in modern building projects. They are commonly used in the construction of bridges, high-rise buildings, warehouses, and other structures where robust support is required.

The most common type of steel beam is the I-beam, named for its characteristic cross-section resembling the letter "I". This shape, with its two parallel flanges connected by a vertical web, provides excellent resistance to bending forces. Other common profiles include H-beams, C-channels, and square or rectangular hollow sections, each offering specific advantages for different applications.

Steel beams are manufactured through various processes, including hot rolling and cold forming. Hot rolling involves shaping steel at high temperatures, while cold forming uses lower temperatures to achieve more precise dimensions. The choice of manufacturing method depends on the required strength, shape, and tolerances of the final product.

The use of stålbjælker offers several advantages. Steel is a durable and recyclable material, contributing to sustainable construction practices. Its predictable behavior under load allows for precise engineering calculations, ensuring structural integrity and safety. Furthermore, steel beams can be prefabricated off-site, which can significantly speed up the construction process and reduce on-site labor costs. Their ability to carry substantial loads over large spans also allows for more open and flexible interior spaces in buildings.
