H4 treated pine sleepers are resistant to rot and attack by termites and borers, making them suitable for in-ground or ground-contact use, including retaining walls and fence posts.
ACQ is the recommended alternative; you will find ACQ commonly being used in garden furniture, picnic tables, exterior seating, children’s play equipment, patio and domestic decking, and hand rails.

Q: What does an H3, H4 and H5 rating mean? A: The H rating for treated pine is an indication of the use to which the timber can be put and its resistance to rot and attack by termites or borers. ACQ means that the pine has been treated in an eco friendly way without the use of arsenic.

These sleepers are also available in a pack of 40, please call us for more information.
