Our H4-treated Alkaline Copper Quaternary (ACQ) timber is a highly durable and environmentally friendly wood treatment option, designed to protect timber from decay, pests, and harsh weather conditions. It is commonly used for fencing, decking, landscaping, and outdoor structures.

Superior Protection – Resists rot, fungi, termites, and other wood-boring insects.
Eco-Friendly – Free from arsenic and chromium, making it safer for people, pets, and plants.
Long-Lasting – Extends the lifespan of timber, even in harsh outdoor conditions.
Versatile Applications – Ideal for fencing, decking, landscaping, and structural use.
Low Maintenance – Requires minimal upkeep compared to untreated wood.
Weather Resistant – Stands up well against moisture, UV exposure, and temperature changes.
Safe for Gardens & Playgrounds – Can be used in raised garden beds, playground equipment, and outdoor furniture.

ACQ-treated timber provides a durable, safe, and sustainable solution for outdoor construction, making it a preferred choice over traditional treatments like CCA (Chromated Copper Arsenate). For best results, always seal cut ends with an appropriate ACQ treatment to maintain full protection.
