Calders and Grandidge is one of the oldest and most well respected names in the UK pressure treated timber sector with over 100 years of experience of producing timber poles, railway sleepers, gates, fencing, and garden products that are made to last.
We are able to pressure treat timber products with Creosote for unrivalled long service life, where appropriate, or Osmose Naturewood for either 15 or 30 year life.
With our own milling and fabrication facilities, and long serving highly skilled staff, we produce our own range of bespoke products as well as working with customers’ unique designs to create one-off items.
We also offer a third party treatment service for both Osmose Naturewood and Creosote.
As proud holders of the Royal Warrant for the supply of preserved timber fencing to Her Majesty The Queen, we take great pride in the products we produce. The fencing we supply can be found at the Royal Stud, and we endeavour to produce all our fencing and gates to the same high standards.
We stock a full range of fencing and gates at all times, and all our stock items are available for nationwide delivery, ready for use.
To see our full range of fencing and gates, together with our landscaping and garden products, please visit our retail website at
Trade accounts available, and stockists required.
