HalleysBlue High Rise Steel Structures are made of Built-Up beams & Rolled Steel sections forming  columns, joists, floor beams & roof Structure in the shape of the letter, Square & Star column sections. The two wide  flanges of a column are thicker and are wider than the flanges on a beam, to better withstand  compressive stress in the Structure. Steel beams are connected to the columns with bolts and  threaded fasteners. The central “web” of the Steel I-beams is often wider than a column web to  resist the higher bending moments that occur in beams.

Trapezoidal Steel deck panels can be used to cover the top of the Steel frame as a “form” or  corrugated mould of thick layer of concrete and Steel reinforcing bars. Another popular alternative is a floor of precast concrete  flooring units with some form of concrete topping. A form of raised flooring system provides the final floor surface with the void between the walking surface and the structural floor being used  for cables and air handling ducts.

The exterior “skin” of our buildings is anchored to the frame using a variety of construction  techniques and following a huge variety of architectural styles. Bricks, stone, reinforced  concrete, architectural glass, sheet metal and simply paint have been used to cover the frame to protect the Steel from the weather.
