The versatile construction system for all design specifications!
A new lightweight floor joist and beam system that can also be used in roof applications such as flat roofs, pitched rafters and purlins.

The SPACEJOIST system consists of parallel stress-graded timber flanges joined with V-shaped galvanised steel webs that are fixed to the flanges by top and bottom nailplated zones. Each SPACEJOIST beam is designed using a patented software package.

Tri-Plate (Click to view products)

The Tri-Plate punched metal connector plates make up our "core" business and are designed and manufactured in strict accordance with local and international codes of practice to provide sound structural timber to timber connections for the prefabricated timber truss and associated businesses. The plates are manufactured in a wide range of sizes in 1mm galvanised rolled steel coil to provide the most cost effective structural joints in prefabricated timber roof trusses.

Tri-Plate punched metal connector plates can also be manufactured in 1,2 mm coil and can be produced in stainless steel or epoxy powder coating for resistance to highly corrosive environments.

Tri-Fix structural timber connector components encompass the most commonly used support elements in the design and erection of timber structures. Please see our Product Range, which details all our most commonly used connectors.

Tri-Design

Tri-Design 3000 is a structural timber engineering software package developed for the specification, design and manufacture of prefabricated timber roof trusses. It offers fully interactive graphical input of modern timber structures and roofs to produce output ranging from design calculations to fabrication detailing and costing. With its powerful features of zoom, windowing and 3-D rotation, from any elevation or angle, it enables the user to view the roofscape from all combinations of direction and distance. It comes complete with its own General Drafting Package (GDP), thus eliminating the need for expensive "add on" costs of stand alone CAD/CAM systems, but if required, it can also be linked to all major CAD software to produce engineering drawings of the highest quality.

Tri-Nail (Click to view products)

The Tri-Nail range of "site application plates" is manufactured by International Truss Systems in 1mm thick galvanised steel coil.

The Tri-Nail range of plates is specifically produced to offer the benefits of "monoplanar" timber truss manufacture in rural or remote areas where electricity and hydraulically operated equipment is not available.

No power or mechanical equipment is required. The individual nails are simply driven into the timber, using a conventional hammer.

Tri-Mate

Tri-Mate is a fully interactive software package designed specifically to meet the needs of professional practices, builders and hardware outlets involved in the daily measurement and specification of building projects and material lists.

Through a "user defined" database, the operator is able to produce a full library of the specific products, quantities and proportions of materials that go into individual building components.

Accurate and professional quotations of simple or highly complicated building structures are achieved quickly through user defined formats.

Tri-Mate can be linked to Tri-Design 3000 to offer unrivalled flexibility in costing out complete building projects.

Tri-Ceil

Tri-Ceil is an innovative ceiling layout, optimisation and costing program, offering the user the ultimate flexibility in quick input and full quantified output of all commonly used ceiling finishes and associated items. Optimisation and on-screen editing allows maximum flexibility in producing cost effective and job winning quotations.

Tri-Truss

Tri-Truss is a comprehensive package recently launched by ITS which is compatible with Autocad 12, 13 and Caddie. Tri-Truss gives the user a quick, efficient and accurate solution to the detailing of prefabricated timber roof trusses. Tri-Truss facilitates truss sections in an instant.
