Our Structural Lumber is manufactured and graded in accordance with the South African Bureau of Standards (SABS) / South African National Standards (SANS) specifications as laid out in SANS 1783:2004/5 to be used in the construction industry. Rance Timber has been a certified mark holder with the SABS, now SANS since 1969 and is audited regularly by SANS inspectors to ensure our compliance with their specifications.
Rance Timber SANS quality lumber is identified by red stamps showing the SANS mark and a triangle containing the letter “R”. The reject timber that does not comply with the grading rules is marked with a black-cross on each end and is not suitable for formal building applications.
Herewith the rough sawn Structural dimensions we produce:
* Denotes the dimensions that are automatically sized during normal production thereof. Sizing of all four sides to produce a smoother finish is available for the other dimensions as well. When sized the rough dimension is reduced by 2 to 4mm. [back to top]
These grades are predominantly used in the manufacturing of furniture or purpose made joinery and moulded products, with the lower grades used for industrial purposes including packaging.
The timber is also graded to SANS specifications under the following categories:
Clear Grade:
Free from any defects including, knots, excessive checking, discoloration, bark / wane, pith, resin pockets and splitting. This is the highest quality of pine available and is mostly used in the production of high quality furniture and mouldings. Distinguishable by black “CLEAR” stamps on the ends.
Select Grade / Appearance:
Graded to a small tight knot specifications and free of the following defects including large knots, excessive checking, discoloration, wane, pith, excessive resin pockets and splitting. This grade is intended for the manufacture of furniture, flooring and shelving or for joinery purposes. Distinguishable by blue “SELECT” stamps on the ends.
Industrial Grade:
This is a lower grade and will contain most of the timber that does not comply with the above grading specifications and thus will include a high degree of the defects mentioned above. This grade can be used in products where appearance is of no real importance, i.e. upholstered furniture, or as a packaging material. Distinguishable by green “INDUSTRIAL” stamps on the ends.
Crating Grade:
Free from any defects including, knots, excessive checking, discoloration, bark / wane, pith, resin pockets and splitting. This is the highest quality of pine available and is mostly used in the production of high quality furniture and mouldings. Distinguishable by black “CLEAR” stamps on the ends.

Crating Grade:
The defects are unlimited in the crating grade and is thus not suitable for any re-manufacturing process other than for producing pallets or crates.
The other defects that are not permissible in any of the above grades are; splits other than end splits, cross-fracture (compression breaks), decay, insect damage or mechanical damage.

We have treatment facilities available to treat the lumber with a CCA (Tanalith) chemical to protect the lumber from decay and insect attack. The treating process involves a vacuum pressure treatment that forces the CCA chemicals to penetrate to the core of the timber under high pressure. All treatment is done after kiln drying and we do not kiln dry after treatment.
The treatment process and the management thereof is done strictly in accordance with the SABS 05:1999 and SANS 10255:2003 specifications.
Herewith the two treatment levels we offer together with their correct applications:

Hazard Class H2:
Lumber destined for interior use above the ground, i.e.: framing, ceiling battens, roof trusses and flooring.

This is a moulded product developed for the use as the “flooring” on a sun deck.
It is machined from 38x114 Select / Appearance grade material to ensure a high quality finish. The decking is ribbed along the length of the board to provide a non-slip finish and has two stress grooves on the under-side to ensure it does not cup. The finished product dimensions are 32mm thick and 110mm wide and is available in lengths from 0.9m to 6.6m in 300mm increments.
The decking is CCA treated to hazard class H3 for exterior use and exposure to the elements and to assist in protecting the timber from decay and insect attack. [back to top]

The secondary processing plant, drymill has the facilities to produce a range of moulded products from the rough sawn timber produced from the main line sawmilling process.
The standard moulded products currently produced include the following:
Ceiling / Panelling: It has a tongue and groove joining system to slot the boards together to cover a ceiling or wall area. It can also be end-matched, i.e. tongue and grooved on the ends, to allow for joining end to end. The profile has a “false V” join down the centre of the board and beveled edges.
Cornice: C-shaped moulding used as a border around the ceiling to hide the ceiling to wall join.
Coverstrip: Flat strip used to cover joins on ceiling.
Fascia / Barge Board: Rounded bull-nose on the bottom edge with stress grooves on the back to stop cupping. Used to surround the edge of a roof on the end of the roof trusses and to attach guttering to.
Flooring: Has a tongue and groove joining system to slot the boards together to cover a floor area. It can also be end-matched, i.e. tongue and grooved on the ends, to allow for joining end to end. The profile is flat with square edges.
Framing: Used in the construction of built-in cupboards. Flat profile with square edges.
Handrail: Used as the top rail on balustrading for a verandah or sun deck. The topside has a flat surface with broad beveled edges and the underside is flat.
Skirting: Flat profile with a rounded bull-nose on the topside and is used as the border on a floor to cover the floor to wall join.
Weatherboard / Cladding: Rounded half-log profile used to clad the exterior walls on a timber-frame construction. The 16mm and 22mm products have a shiplag joining system and the 32mm a tongue and groove system. [back to top]

The bark is striped off the logs before the sawmilling process begins and thus becomes a by-product of the sawmilling operation. As a process of managing our waste we compost the bark over a period of time and market it as a growing medium.
The composting processing is simple but time consuming. It involves stacking the bark in large wind rows, adding water and turning the stacks regularly. The water helps to leach out the harmful tannins and the turning aerates the stack to assist in the composting process. The only chemical added is Urea to speed up the composting.
Once composted, the growing medium is tested by a local agricultural research station to ensure it has been composted sufficiently to be used as a growing medium.

This is used predominantly by seedling farmers to germinate the seed in seedling trays, or for potting soil in a domestic garden application.
Garden Mulch, Fine: Particle Size 10mm to 12mm.
This product is used as a mulch on top of flowerbeds to help retain moisture and prevent the growth of weeds. It can also be used in hydroponic tunnels.
Garden Mulch, Coarse: Particle Size 13mm to 19mm.
It can be used for the same purpose as the fine garden mulch or as decorative ground cover.
The most popular product for hydroponic tunnels is the composted but un-sifted medium consisting of all of the above sizes and bigger, up to ± 20 to 30mm. This has an excellent consistency to retain the right amount of water required by the plant and to hold the root structure firmly. Customers using this product have recorded up to a 15% saving on water and fertilizers as apposed to other growing mediums.
The Envirogro products have been successfully used to grow a wide range of seedlings, flowers and vegetables in hydroponic tunnels; namely, various vegetable seedlings, pine seedlings, eucalyptus seedlings, many flowers such as roses and vegetables including tomatoes, peppers, blueberries, strawberries and mushrooms.
