Teräspalkit

Teräspalkit, or steel beams, are structural elements used in construction to support and distribute loads. They are typically made from steel, a strong and durable material that offers excellent tensile strength and resistance to deformation. Steel beams are widely used in various construction projects, including buildings, bridges, and industrial structures, due to their high strength-to-weight ratio and versatility.

Steel beams are manufactured through a process that involves heating and rolling steel billets into the desired shape. The most common types of steel beams include I-beams, also known as H-beams or universal beams, which have a distinct I-shaped cross-section. This design provides excellent resistance to bending and shear forces. Other types include angle beams, channel beams, and T-beams, each with specific applications depending on the structural requirements.

One of the key advantages of teräspalkit is their ability to span long distances without the need for intermediate supports. This makes them ideal for large open spaces, such as warehouses, auditoriums, and bridges. Additionally, steel beams are resistant to fire, termites, and rot, making them a durable choice for various environmental conditions. They are also relatively easy to fabricate and assemble, allowing for efficient construction processes.

However, steel beams can be susceptible to corrosion, especially in environments with high humidity or exposure to saltwater. To mitigate this, protective coatings, such as paint or galvanization, are often applied. Despite this potential drawback, the benefits of using steel beams in construction generally outweigh the disadvantages, making them a popular choice for structural applications.
