We have built a strong reputation as one of the oldest and most well respected names for the supply of pressure treated timber fencing to the agricultural, equine, local authority and domestic markets.
We are able to pressure treat timber with creosote for unrivalled long service life, or Celcure for a 15 to 30 year desired service life. Creosote pressure treatment not only extends the service life expectance of timber products but is particularly useful in agricultural applications as animals will not chew on creosoted timber.
All our products are manufactured from high quality european softwood timber sourced from sustainable certified forests. After harvesting all timber is inspected to ensure it meets the standards required to produce high quality fencing.
Timber is either kiln or air dried to below 28% moisture content prior to treatment. This leaves space on a cellular level for our pressure treatment impregnation chemicals to permeate the timber and remain in place throughout their service life.
Once the timber arrives on site it is machined as required in our mill to produce our range of high quality fencing products.
Bespoke designs can be produced specifically for customers with unique design requirements.
Softwood timber is next pressure treated with either green or brown Celcure solution to enhance the desired service life of the finished product. Post treatment any Calders & Grandidge fence will have a desired service life of 15 years. We do offer 30 year desired life treatment where applicable.
We only ever treat timber with Celcure solution once it has been cut to its final dimensions. This ensures that all exposed surfaces absorb the treatment equally, resulting in a better quality product.
