Steel Structure

Steel structure is a metal structure which is made of structural steel* components connect with each other to carry loads and provide full rigidity. Because of the high strength grade of steel, this structure is reliable and requires less raw materials than other types of structure like concrete structure and timber structure.

In modern construction, steel structure is used for almost every type of structure including heavy industrial buildings, multi-storey buildings, equipment support systems, infrastructure, bridges, towers, airport terminals, etc.

From big city skyscrapers to clean energy projects, GREN STEEL successfully partners with building and industrial steel fabricators on a variety of construction projects. With decades of experience specializing in steel girder fabrication, we can take on the most challenging weldments in your steel structure. Increase your next project's efficiency by working with us.

Depending on each project’s applicable specifications, the steel sections might have various shapes, sizes and gauges made by hot or cold rolling, others are made by welding together flat or bent plates. Common shapes include the I-beam, HSS, Channels, Angles and Plate.
