Timber Grade Information
|GL8||The GL Grading system stands for Glue Laminate and indicates that the timber product has been engineer manufactured utilising an adhesive bond. The timber is then tested to measure a variety of performance characteristics including strength & flex before finally being assigned a certified rating on the GL Scale. Glue Laminated timber varies in manufacturing methodology with finger-joint lamination of timber shooks and split lamination of longer timber lengths being the most common. GL8 Rated timber is suitable for a wide variety of structural applications and is sought after for it’s impressive span & stablity. The visual properties on GL timber vary based on the quality of the timber material components used in the manufacturing process, the type of glue used and the precision of the machining.|
|F7||This visually stress-graded rating is a popular choice for use in decks and pegolas. Often prefered by builders for its strength, flex and cost qualities.|
|F7 OPG+||F7 strength graded with a visual override to ensure selection of the best boards for your project. Accurately sized and machined with no knot holes or wane included. What is visual override? Unlike Machine Graded Pine (MGP10 etc), Visual Override F7 is personally visually inspected by trained professionals to ensure that each length of timber meets a quality standard. This means you get timber that is clearer, with fewer knots which results in less wastage. Whenever you are using timber that will be viewable we recommend that you insist on timber that meets this uncompromising standard.|
|MGP- Grade||MGP 10 Machine Stress Graded timber as used in frame & truss manufacture. MGP is a test of stiffness, with no regard to wane, knots or visual appearance. We recommend for use in unseen structural appplications, such as walls, roof spaces etc.|
|H2||Internal use, protection against termites.|
|H3||Outdoor, above-ground use.|
|H4||Outdoor, in-ground use.|
|H5||Outdoor, wet in-ground use.|
|MicroPRO||MicroPro technology is a revolutionary way to pressure treat wood for decks, fences, landscaping and general construction uses. One of the key benefits of MicroPro is that it contains zero arsenic – making it suitable for use in playgrounds & compliant with government projects. MicroPro pressure treated wood is treated with micronized copper preservatives, which help protect against termite damage and fungal decay. MicroPro offers many benefits including significantly improved corrosion performance. The Osmose MicroPro technology is the first treated wood process to be certified under Scientific Certification Systems Environmentally Preferable Product (EPP) program based onLife-Cycle Assessment.|
|LSOP||Light Organic Solvent-borne Preservative. LOSP is a solvent-borne preservative treatment of pine timber. The organic solvent takes the preservative into the wood and is drawn out in the last stages of treatment leaving the preservative in the wood. LOSP treated pine has long lasting protection against decay and insect attack. LOSP treated timber is great for appearance applications such as external joinery, due to it leaving the light coloured appearance unchanged after treatment.|
|ACQ||Alkaline Copper Quaternary. ACQ is a water-borne preservative treatment of pine timber. The ACQ treatment process is similar to CCA but is free of arsenic. Instead uses copper and ammonium compounds as agents against insect attack, fungi, termites and wood boring insects. After pine has been treated with ACQ its appearance can range from dark green to brownish green and can be stained or painted once dry.|
|CCA||Copper, Chromium and Arsenic salt. Due to the Arsenic present in CCA treated timber it is not safe for use on playgrounds and is generally not approved for use on government projects. CCA is a water-borne preservative treatment of pine timber. CCA is pressure impregnated into the wood and has a high resistance to chemicals leaching out of the timber over time. This high resistance is due to the chromium which locks in the elements of copper and arsenic into the wood. The arsenic and copper elements protect from insect and fungal attack. Pine which has been treated with CCA is clean, odourless and has a slight green colour.|
- Timber be MUST be keep DRY until it has been SEALED.
- Timber MUST be SEALED with PAINT, STAIN or
- OIL prior to or soon after installation.
- ALL CUT ENDS MUST BE RESEALED
Important General Care & Maintanance of Natural Timber Products
Timber is a natural product and will age & sometimes react adversely to normal changes in weather conditions. For this reason it is important to protect timber with a high quality paint, oil or other sealant. Timber must always be stored in dry location and must be sealed prior to or immediately after the timber is installed. When cutting treated timber it is important to reseal all cut ends with an approved timber preservative such as Tanalised EnSeal (or equivalent). This includes but is not limited to cuts, notches, drill holes and rebates. Resin may bleed from timber and to minimise the effect of this it is adviseable to use a quality primer and paint in light colours. It may be necessary to recoat as required.
Southern Select GLULAM Beams & Posts are treated with MicroPRO, which comes with a 50 Year Limited Guarantee* against rot & insect attack. For all information regarding this guarantee please visit www.osmose.com.au Here. Or download the Osmose Australia: Treated Product Guarantee Information Sheet
Osmose also offer some important information regarding the MicroPRO treatment which can be found in the MicroPRO Brochure Here.
OSMOSE IMPORTANT INFORMATION
- MicroPro Pressure treated timber has corrosion rates on metal products similar to CCA (chromated copper arsenate) pressure treated timber and untreated timber. For interior or exterior applications, use fasteners and hardware that are in compliance with the manufacturer’s recommendations and the building code for their intended use. Where design and or actual conditions allow for constant, repetitive or long periods of wet conditions, only stainless steel fasteners should be used. When using aluminium products in conjunction with MicroPro treated timber, refer to the MicroPro Fastener and Hardware Information Sheet for additional information.
- Do not burn preserved timber.
- Wear a dust mask and goggles when cutting or sanding timber.
- Wear gloves when working with timber.
- Some preservative may migrate from the treated timber into soil/water or may dislodge from the treated timber surface upon contact with skin. Wash exposed skin areas thoroughly.
- All sawdust and construction debris should be cleaned up and disposed of after construction.
- Wash work clothes separately from other household clothing before re-use.
- Preserved timber should not be used where it may come into direct or indirect contact with drinking water, except for uses involving incidental contact such as fresh water docks and bridges.
- Do not use preserved timber under circumstances where the preservative may become a component of food, animal feed, or beehives.
- Do not use preserved timber as mulch.
- Only preserved timber that is visibly clean and free of surface residue should be used.
- If the timber is to be used in an interior application and becomes wet during construction, it should be allowed to dry before being covered or enclosed.
- Disposal Recommendations: Preserved timber may be disposed of in landfills or burned in commercial or industrial incinerators or boilers in accordance with federal, state, and local regulations.
- If you desire to apply a paint, stain, clear water repellent, or other finish to your preservative treated timber, we recommend following the manufacturer’s instructions and label of the finishing product. Before you start, we recommend you apply the finishing product to a small exposed test area before finishing the entire project to insure it provides the intended result before proceeding.
- Mould growth can and does occur on the surface of many products, including untreated and treated timber, during prolonged surface exposure to excessive moisture conditions. To remove mould from the treated timber surface, timber should be allowed to dry. Typically, mild soap and water can be used to remove remaining surface mould.
- Projects should be designed approved and installed in accordance with federal, state and local regulation governing construction in your area. The MicroPro Treated Timber Process is certified under SCS’s Environmentally Preferable Product (EPP) program based on Life-Cycle Assessment.
