BNS Basement Contractors Structural Steelwork London

Steel is an alloy of iron and small amounts of carbon. Structural steel is one of the most widely used building materials in construction. Structural steel has many properties, including: high tensile and compressive strength, ductility, durability, and light weight.

Beams and columns are joined together to form a skeleton that supports components in construction projects. The skeleton forms a gridlike frame that reinforces concrete, which has low tensile strength and ductility. It supports the floors, walls and roof.

Standard Frames

Multi-span rigid frames

By using columns as interior supports, these can provide unlimited strength. Supporting columns are placed where strength is needed. This type of frame is necessary when you have large interior spaces.

Arch buildings

These are popular as they are easily assembled. They are self-supporting structures, without any interior supports, such as: columns, trusses or beams. The exterior sheeting makes up the wall, ceiling and roof.

Single-span rigid frames

These frames create a covered space, with no need for interior columns, with a beam providing support at each end. An average single-span building can reach up to 120 feet wide.
