Frequently Asked Questions

Q: What is a composite joist?

A: A composite joist, also known as a composite steel joist, is a type of structural member used in construction to support floors and roofs. It is made by combining two or more materials, usually steel and concrete, to create a stronger and more efficient joist.

Composite joists typically consist of a steel top chord, a steel bottom chord, and a concrete slab sandwiched between them. The steel chords provide tensile strength and rigidity, while the concrete slab provides compression strength and mass. The combination of these materials results in a lightweight and durable joist that can span long distances and support heavy loads.

Composite joists are commonly used in commercial and industrial buildings, as well as in multi-story residential buildings. They offer several advantages over traditional joists, including increased strength, stiffness, and fire resistance, as well as improved acoustic and thermal performance.

Q: What is structural flooring?

A: Structural flooring refers to a type of flooring system that is designed to provide both a walking surface and structural support for a building or structure. Unlike non-structural flooring, such as carpet, vinyl, or tile, structural flooring is capable of bearing heavy loads and transferring them to the building's foundation or support structure.

Structural flooring is commonly used in commercial and industrial buildings, such as warehouses, factories, and distribution centers, as well as in multi-story residential buildings. It is also used in bridge construction, where it serves as both a roadway and a structural element.

There are several types of structural flooring systems, including concrete slabs, precast concrete planks, steel decking, and composite joists. The choice of flooring system will depend on a variety of factors, including the building's design, the required load-bearing capacity, and the desired aesthetic appearance.

Overall, structural flooring plays a critical role in the overall strength and stability of a building or structure, and it is an essential component of any construction project that requires durable and reliable support.

Q: What are steel trusses?

A: Steel trusses are a type of structural element commonly used in the construction of buildings, bridges, and other structures. They are typically made from steel beams arranged in a triangular pattern, with each beam forming one side of the triangle.

The triangular shape of steel trusses provides excellent strength and stability, allowing them to span long distances and support heavy loads without the need for intermediate columns or supports. This makes them ideal for use in large, open buildings and structures, such as warehouses, factories, and sports arenas.

Steel trusses can be manufactured in a variety of shapes and sizes, depending on the specific needs of the project. They can be straight or curved, and may be designed to have a single or multiple web configurations. Additionally, they can be bolted, welded, or riveted together to form larger assemblies, depending on the required load capacity and structural performance.

Overall, steel trusses are a versatile and durable structural element that offer many advantages in terms of strength, stability, and ease of construction. They are commonly used in a wide range of applications and are an essential component of many modern construction projects.
