The King Post truss

A single vertical web and is used over very short spans. Typically you may see a king post truss in your porch, shed or garage.

The Queen Post truss

A fan web configuration: a single vertical web and two diagonals. This truss type is used less frequently because as spans increase, fink truss usually provides an cheaper alternative.

Queen Post Roof Truss

The Fink Truss

The most frequently used web configuration of common roof truss is the Fink roof truss; easily recognised by its W-distribution of internal webs. The fink roof truss can be used for the simplest garden shed to industrial complexes.

Fink Truss

The Howe truss

A special type of truss, most often used to support other trusses and taking the form of multi-ply roof truss girders.

The Raised Tie Truss

Allows lifting of the ceiling tie from the bearing height, the designer can produce a vaulted ceiling having a flat middle section and two sloping sides.

The Mono Truss Profile

Mono trusses have only one rafter, producing essentially a right-angle triangle. They are used to form single pitched and lean-to roofs.

The Double Pitch Profile

A Common truss having rafters at different angles becomes a Double Pitch truss. These may be the result of architectural requirement; dual pitch roofs are used frequently in industrial applications. Dual Pitch trusses may also be required when matching new to old roof lines.

Scissor Truss Profile

The scissor truss has two bottom chords meeting at an apex and having a ceiling pitch. With variable rafter and ceiling pitch, the scissor truss can provide interesting roof shapes, also providing designers with an opportunity to use vaulted ceilings.

Attic Truss Profile

Room-in-the-Roof or Attic truss profiles have become increasingly popular, offering the possibility of extra living space in the roof. Attic rooms can significantly increase the value of a property whilst providing better value for money than a built extension.

Attic trusses are extremely versatile, incorporating roof lights, dormer windows and balcony areas. We are also able to provide Attic trusses incorporating engineered floor joists, providing greater design opportunities.
