Illingworth Ingham (M/cr) Ltd is now a leading supplier of Keruing in the UK. Keruing is a hardwood mainly used for trailer decking, industrial flooring, piers and marinas. It is generally chosen for this type of use due to its load bearing strength, its hardness and durability and its relatively low cost.
Keruing generally compares with teak in most strength categories, but it is a little stiffer, and about 40 per cent more resistant to shock load.
Keruing comes from South East Asia and our stocks are all PEFC certified.
At Illingworth Ingham (M/cr) Ltd we are able to supply rough sawn Keruing or machined to a specific profile. We have a number of popular profiles, shown overleaf, but we can also create bespoke profiles to your own design.
Sapwood – greyish-brown and distinct, and usually 50mm to 75mm wide.
Heartwood – varies from light red to reddish-brown or brown, darkening on exposure.
Grain – reasonably straight with an occasional interlocking grain
Durability – Moderately durable
Density (mean, Kg/m³) – 740 kg/m³ approx. (Density can vary by 20% or more)
Texture is moderately coarse but even.
The timber contains an oleo-resin which exudes in a number of pieces especially on the end grain.
Drying – Keruing dries slowly, and it is difficult to achieve uniform drying particularly in thick stock. High temperatures aggravates the release of the resin, and care is therefore needed in order to reduce this to a minimum and also to reduce the tendency for cupping to occur.
There is high shrinkage during drying, and a corresponding high movement potential.
Machining– To combat this shrinkage Illingworth Ingham (M/cr) Ltd face the timber first to regularise the timber and then re-machine it to the required profile. This produces the best possible machined finish possible.
Moisture Movement – Medium
