H-profile steel, also known as H-beam or I-beam, is a type of structural steel that has a cross-section in the shape of the letter "H". This economical and efficient material offers a better arrangement of sectional area and a reasonable proportion between strength and weight. It is widely used in industrial plants, civil buildings, bridges, electrified brackets of railways, and other building projects due to its advantages in bending ability, simple construction, low cost, and light weight.

A sunroom, also known as a solarium or sun porch, is an extension of a home designed to enjoy natural sunlight while providing a comfortable indoor space. These rooms are typically made of large glass windows and/or glass walls to maximize sunlight exposure, turning them into a bright and inviting environment.

Z-section steel is a versatile and strong steel profile, shaped like the letter "Z", commonly used in construction and structural engineering. It is often employed in building frames, support beams, and other structural components due to its ability to provide robust support and resistance to bending and twisting.

Steel roof sheet is a durable and long-lasting roofing material made from high-quality steel. It is designed to provide protection against harsh weather conditions, including heavy rain, strong winds, and extreme temperatures. Steel roof sheets are available in a variety of colors and profiles, making them suitable for a wide range of architectural styles.

Steel sandwich panels are a type of construction material that consists of two outer layers of steel sheets and a core material, such as polyurethane, polystyrene, mineral wool, or rock wool, sandwiched between them. These panels are commonly used in the construction of walls, roofs, and floors in buildings, as well as in the manufacturing of industrial and commercial structures.
