Timber & Building Board

Structural Quality for Every Project

From roof structures and wall frames to flooring and ceiling finishes, timber is at the heart of most building projects. Rouberto Building Materials stocks a wide range of structural and treated timber, plywood, building boards and sheet materials to support both professional contractors and hands-on homeowners.

We carry standard lengths and sizes, and our team can advise you on the right product for your specific application — whether you’re building a new structure, doing renovations or tackling a weekend DIY project. Delivery to your site across Randburg and surrounding suburbs is available.

Products we offer

Structural Timber
(South African Pine)

Structural Timber (South African Pine)

SA pine is the most widely used structural timber in South Africa for roof trusses, wall plates, purlins, brandering and general framing. Available in a range of standard lengths and dimensions.

CCA Treated Timber

Chromated Copper Arsenate (CCA) treated timber is pressure-impregnated with preservative to resist rot, insects and fungal decay. Essential for any timber in contact with soil, concrete or moisture — including fence poles, decking subframes, pergola posts and sleepers.

Plywood

Structural and general-purpose plywood in a range of thicknesses (6 mm to 25 mm) for flooring, shuttering, wall lining, furniture and exterior cladding. We stock standard 2440 x 1220 mm sheets.

OSB (Oriented Strand Board)

Oriented Strand Board is a structural panel made from compressed wood strands, used for wall sheathing, flat roof decking, flooring and hoarding. A cost-effective alternative to plywood for many structural applications.

Chipboard & MDF

Chipboard and Medium Density Fibreboard (MDF) for interior joinery, shelving, cabinets and non-structural applications. Available in standard sheet sizes.

Ceiling Board

Fibre cement and gypsum ceiling boards for residential and light commercial ceilings. Available in various thicknesses and board sizes to suit different ceiling systems.

Brandering & Battens

Timber brandering strips and roof battens used for ceiling systems, tile fixing and internal wall lining applications. Sized to match standard ceiling board and tile systems.

Door Frames & Skirting

Pre-made timber door frames and skirting board profiles for internal and external door installations and floor/wall junctions.

Frequently Asked Questions

What is CCA treated timber and do I need it?

CCA stands for Chromated Copper Arsenate — a preservative that is pressure-forced into the timber to protect it against rot, insects (including termites) and fungal decay. Any timber that will be in contact with the ground, set into concrete, exposed to continuous moisture or used outdoors should be CCA treated. This includes fence posts, pergola posts, decking beams and sleepers. Untreated timber in these conditions will deteriorate quickly. Our team can help you identify which applications require treated timber.

What thickness of plywood should I use for flooring?

The correct thickness depends on the joist spacing and the load requirements of the floor. As a general guide: for joists spaced at 400 mm centres, 18–20 mm structural plywood is typically used for standard residential flooring. For joists at 600 mm centres, 22 mm or thicker is recommended. For mezzanines or floors carrying heavier loads, a structural engineer should specify the correct thickness. Our team can guide you based on your specific joist layout.

What is the difference between plywood and OSB?

Plywood is made from thin sheets of wood veneer glued together in alternating grain directions, giving it good strength, rigidity and a relatively smooth surface. OSB (Oriented Strand Board) is made from wood strands compressed and bonded with resin in a specific orientation, giving it comparable structural properties at a generally lower cost. OSB has a rougher surface and is more susceptible to edge swelling when wet, but is an excellent and widely used structural panel for many building applications.

How do I prevent timber from warping or splitting?

Warping and splitting are usually caused by uneven moisture gain or loss. To minimise this: store timber flat and off the ground in a dry, well-ventilated area; avoid exposing it to direct sunlight or rain before installation; seal cut ends on site if possible; and use the correct fixing method for the application. Using kiln-dried timber where dimensional stability is important also helps. Our team can advise you on the best storage and handling practices for your specific project.
