Growth through premier brands and innovation
Since establishment in 1987 in Five Dock, NSW, Independent Timber Importers has been on a mission to redefine the timber industry wholesale/distribution landscape. ITI has worked closely with industry suppliers, customers and associations to promote the strength, beauty and environmental benefits of using timber. At the same time ITI redefined the role of the wholesaler with its distribution and service models. With its large investments in distribution centres, product development, people and service standards; in early 2002 ITI dropped the name Independent Timber Importers and replaced this with ITI and introducing the new logo with the “Innovative Timber Ideas” phrase which more accurately describes the attitude of the company.
Today ITI consists of 9 distribution sites across Australia with over 130,000m2 of undercover storage, a state of the art re-manufacturing, treating and priming plant in Chile, an office in Indonesia, 3 distribution locations in New Zealand and growing sales in the USA.
True to its name, the success of ITI lies in its commitment to innovation in both service and product development. This commitment has led to premier brands such as Design Pine, EziTrim Plus, Spec LVL products along with the distribution of market leading products such as Metsa Wood, EvaLast, James Hardie, Weathertex and Modwood. ITI has also led the way with service standards winning countless industry awards for its service.

600mm Max. Spacing between nails
600mm Max. Spacing between nails
Where multiple ply studs are required they are to be laminated using framing nails, or minimum 10 gauge screws, at 600mm centres maximum. Drive fixings alternately from either side of studs where possible.
Where multiple plates are required 2x nails are required to be installed at no greater than 600mm centres. All joists in bottom plates are to be over floor joists, solid block or over a concrete slab.
Where multiple Top Plates are used, joints are permissable off stud however if a rafter or truss are supported over the plates span additional blocking is required under the joint.
HOLES & NOTCHES IN WALL FRAMING
TOP PLATE CRUSHING
ITI Spec Frame 10.0 is a light weight timber product which provides the end user with numerous benefits. As a result of this light nature additional attention should be given when assessing point loads which have been applied to the top plates.
(1) Capacities for ‘Without Bearing Plate’ governed by the bearing area supported beam onto the Top Plate
(2) Capacities for ‘With 140x75x6mm Bearing Plate’ governed by the bearing area of the support studs under the Top Plate
(3) Values shown for a categry 1 member per AS1720.1. Where
Roof Battens
Roof Battens are members which span over and across rafters. They are designed to support the roof covering only. Roof Battens are installed on the flat and are to span across a minimum of 3 rafters.
Guide Notes
1. Refer to page 3 of this guide to check product availability in your area
2. Refer to page 4 of this guide for span and span type definitions
3. All members to be installed per the AS1684 series of standards and good building practice
4. Member sizes specified are based on serviceability criteria outlined in AS 1720.3
5. Where members are supporting roof loads a maximum roof pitch of 25 degrees has been accounted for in calculations. Refer to the factor table below to determine other results
6. N3 wind load have been applied to all members listed inside the specifcation guide
7. Where wall frames are over 3.0m, and exceed the parameters of AS 1684, an engineer should be engaged to confirm the members selected and ensure all structural considerations have been met
8. Floor joist spacings / centres should be selected as such to obtain adequate support for flooring / floor sheeting
9. Flooring to be installed per AS1684.2 and AS1684.3. Particle board flooring to be installed as AS1860.2
10. Rafter and Ceiling joist spacings / centres should be selected as such to obtain adequate support for Roof sheeting or Ceiling Material respectively. Refer to product manufacturer for details
11. Always confirm the required roof batten centres against the roofing manufacturers recommendations
12. Maximum roof load width of 9000mm considered across all applicable wall framing designs
13. Increments of 0.5m2 of load area considered for concentrated load studs
14. Nominal loads have been applied to framing members in accordance with AS/NZS 1170.1
15. Floor live loadings based on residential 1.5 kPa distributed & 1.8 kN concentrated live loads
16. Floor dead loads based on 40 kg/m2 for 19mm particle board flooring and 10mm plasterboard ceiling
17. Concentrated Load Studs are designed to support verticle loads only. No horizontal wind loads have been considered
18. Concentrated load studs must be used as part of a wall frame
19. Raking Wall Studs are not designed to support any roof framing. Where outriggers cantilever off the top of the wall the studs should be designed with the appropriate roof load width
20. Member sizes nominated are based on the product being fully protected from moisture and maintains an average moisture content of 15%, or less, over a period of 12 months i.e. K4 = 1.0 per AS1720.1 clause 2.4.2.3.
21. Member sizes nominated are based on construction in coastal areas south of latitude 250 and south of latitude 160 in all other areas i.e. k6 = 1.0 per AS1720.1 clause 2.4.3
PRODUCT HANDLING & STORAGE
ITI Spec LVL products – like all other engineered wood products – must be handled and stored properly and carefully. Incorrect handling and storage may introduce defects on product’s surfaces, edges or corners. Furthermore, the dimensional stability of the product may suffer.
Transport
While transporting or storing the product, increased moisture caused by rain or splashing must be avoided. If ITI Spec LVL products products are moved with a forklift truck, wide enough forks must be used in order to avoid damaging the product. When lifting several packs at a time, the distance between forks must be wide enough to ensure safe lifting. Surface-treated products should be delivered direct to site without additional, unnecessary off-loading during delivery.
Storage
ITI Spec LVL products must be stored under cover. When storing the products temporarily on site, a solid, straight and dry platform should be used. The height of ground bearers must be at least 300 mm. To avoid twisting of the product, the bearers between packs must be aligned vertically with the ground bearing timbers.
The plastic wrapping of each pack must be cut open from underneath to enable moisture to evaporate from the bundles. If the products are stored on site for longer than one week, the bundles must be covered with an additional protective covering. Conditions of the products and protective cover must be monitored regularly during storage.
Handling
ITI Spec LVL product packs may be unloaded on site with either a forklift or a crane. Approved webbing slings must be used if unloading with crane. It is forbidden to use chains or wires.
If unloading is done manually, the pack is opened and the products are carried one-by-one. While cutting the banding, beware of band’s ends. ITI Spec LVL products should not be dragged or dropped.
ITI Spec LVL is a light-weight material and is easy to shape, which means notable time and cost savings in construction. ITI Spec LVL products can be processed with conventional wood working and power tools. There is no need for separate specialist tools.
