Our Redwood Strainers offer a versatile and hard wearing option for a range of general purpose fencing and garden landscaping projects. They are produced from Pine Redwood because of its greater treatability. All of our Pine Strainers are high pressure treated through our ISO9001 treatment process to User Class 4. This protects them from decay and insect attack and making them suitable for use in ground contact. Purchased from sustainable sources they come with either FSC or PEFC Certification.
