Be it wooden fencing or wooden bridges in your garden, you must use treated timber for longevity and cost-effectiveness. In South Africa, the SABS (South African Bureau of Standards) controls treatment of timber for DIY projects as well as professional timber supplies.
The Importance of SABS Standard
Whether you need tapered poles for fencing or machine-turned cylindrical poles, make sure that they are treated as per the SABS standard. Pinus and Eucalyptus are the most common commercially grown species in South Africa. These species of timber are not durable and need to be treated for longevity and strength.
Different SABS Specifications for Different Timber Products
In South Africa, SABS specifies TANALITH Treatment as the best way to treat timber poles so that they are not affected by leach or vegetation and are weather resistant. Make sure that the tapered poles you buy for wooden fencing meets the SABS 457 specification and cylindrical poles meet the SABS 1288 specification.
Check for the SABS Mark
You may have to opt for different types of timber treatments for different types of building projects. You should check with your timber supplier to know about the correct treatment specifications to suit your project. It is advisable to buy timber that carries the authentic SABS mark. SABS mark on timber products indicates that the correct type and amount of preservative has been used to treat the timber.
