RC Frame

From flat developments to car parks, RC frames use reinforced concrete structures and advanced machinery to undertake complex more complex projects. Often RC frames are used for restricted areas.

Steel Frame

Steel frames are a very high strength yet low weight way to form the structure of a building. Most commonly steel frames are used to span over large distances such as high rise properties, industrial warehousing and other superstructures.

ICF (Insulated Concrete Form)

This method is unique in the sense that it requires on site building; concrete is poured into a hollow frame which is then reinforced with steel. ICF is a popular choice for residential developments as it energy efficient and provides a great layer of insulation.

Concrete Frame

Typically used on concrete foundations, concrete frames consist of a network of beams which form the structure of a building. Concrete frames are a particularly heavyweight option which are used to support the weight of floors, roofs and walls.

Structural Openings

Structural openings are often necessary to support the wall surrounding any new openings. This helps with the stability of the property and the support of the structure above.

Portal Frames

This method is most often used on low structures such as industrial units and retail properties. Portal frames use columns which are connected together and are popular for large areas.

Goal Post Frames

Goal post frames are effective to support a structure when a wall has been removed, taking the weight that the wall initially held to keep the property secure.


Pynford Beams

Used to create an open plan space, opening a frame or working below other premises, Pynford beams are placed right below the ceiling to offer support to the remaining walls.


In-situ Concrete Beams and Columns

In-situ beams and columns offer more flexibility as they are assembled on site according to your project requirements. Once in-situ beams or columns have been implemented however, they can be very limiting if future changes are required.


Crane Bases

Crane bases can be used as either a permanent fixture if needed or for temporary purposes during building projects. The details of the crane base needed will be supplied by the crane supplier.
