Floor Joist Systems
Metal web floor beams are an “OPEN” web floor product that utilises the combined benefits of lightweight kiln dried stress graded timber chords with the stiffness of a metal web construction.
These qualities combine to provide a high strength, lightweight floor beam that is engineered to precise dimensions in short or continuous lengths that provide the facility for fast and easy installation of services such as pipes, cabling trunking and ducts. The long lengths and wide joist widths improve the quality and speed of both floor decking and plasterboard ceilings, making this a very desirable floor system for both domestic and commercial applications. Open web beams can also be used as rafters to form wide, open plan attic space, or they can be designed as a stressed floor diaphragm as part of our space frame platform system. metal open web joists>>
The System 42 FloorTrus™ system provides many of the benefits of the metal web system with the added advantages of infinitely adjustable joist depth options. All timbers are on the “flat” giving a wide width to facilitate fast and easy installation of joists, decking and ceilings but because all of the internal webs are specifically cut to length this system allows joists to be manufactured to any specified depth and like the metal web systems the use of kiln dried and stress graded chords reduces shrinkage to a minimum. The nature of the FloorTrus™ system also means the system enjoys the added benefit of being able to design many different bearing details and web patterns. These features together with the capability of designing into beams “trimmable” ends, make FloorTrus™ the most flexible of all the engineered floor beam systems currently available. FloorTrus™ has been sound tested and fire tested by the BRE for both 30 minutes and 60 minutes (report numbers 231884, 230795 and 230475 respectively).
FloorTrus™ beams can be used as rafters to form wide, open plan attic space, or they can be designed as a stressed floor diaphragm as part of our space frame platform roof system. web beams and joists>>
