Steel Framed Buildings

Designing and Constructing steel framed buildings in South East England since 1988.

At Directline Structures, we specialise in steel framed buildings, mostly in Kent and the South East, but also around the UK. We have the knowledge and experience to design and build your project on time and on budget. Every project is different and we will use whichever construction method is appropriate, but in many cases a steel frame can improve functionality, broaden possibilities and reduce construction and maintenance costs.

We have built hundreds of steel framed buildings; not only industrial projects but schools, offices and community buildings as well. The advantages of a steel frame include:

Industrial steel framed buildings

  • Easy integration of traditional elements such as brickwork, glazing, timber etc…
  • Large spans allow you to create rooms and spaces without interior columns.
  • The strength of steel allows for impressive engineering, canopies and overhangs.
  • Steel with high yield strength reduces weight, thus optimising the transportation and handling costs whilst meeting all design criteria requirements.
Our extensive and ongoing relationship with Lindab Buildings means that we understand how to get the best building for your budget.
