Structural Material

This is the structure that needs to be created before laying your deck planks. Important consideration must be paid to the type of material used for your structure because your deck is only as good as the structure which it is built on.

Structural Pine

Application: Used to secure with composite clips into the timber sub-structure

Structural SA Pine

SA Pine is a soft wood which is commercially grown in South Africa. Its inexpensive and very suitable for using as a sub-structure for your deck, as long it is SABS graded (minimum S5), has been CCA treated and is of the correct Hazard classification for its intended use.

CCA Treating:

Is the process of pressure treating SA pine, whereby a solution of chromium, copper, and arsenate is impregnated into the timber to preserve it and give it a longer life expectancy. The chromium acts to help the other chemicals bind and fix into the timber. The copper acts to protect the wood against decay, fungi, and bacteria, and the arsenic provides protection from wood-attacking insects.

Hazard Classifications – (H) Classifications:

H2 for internal use
H3 for external above ground
H4 for in-ground contact
H5 for submersion in fresh water
H6 for submersion in salt water.

SABS Structural Grade

S5 grade indicates that it complies with a certain stress grade, which is related to specific strengths. The higher the number the higher the strength properties of the timber.

Structural Balau

Application: Used to secure with composite clips into the timber sub-structure

Structural Balau

Balau is a heavy Hardwood that is very durable and long-lasting, it has extremely strong structural properties and is recommended for structural use. It contains toxins that provide protection from wood-attacking insects and is high in resins and oils which naturally repel water and limit rot. If no oil or seal is applied, Balau will naturally oxidise to a light grey colour. Balau Structural Timber can also be used for Screens, Balustrades, Pergolas, etc.
