(100000 in stock)

H3 Treated MGP10 Pines are high-grade structural pines treated to withstand decay, termites, and harsh weather conditions. They are ideal for outdoor use in applications such as decking, pergolas, fencing, and other exposed structures. The H3 treatment ensures long-lasting durability, making them perfect for areas that are above ground but exposed to the elements. With a strength rating of MGP10, H3 TREATED these pines provide both reliability and resilience for construction and outdoor projects.

140 x 45 MGP10 H3 combines MGP10 structural grading with H3 preservative treatment, making it suitable for above-ground outdoor applications exposed to the weather — pergolas, deck framing, exposed beams and outdoor structures. The H3 treatment protects against decay and termite attack in above-ground, weather-exposed conditions.

Where a project needs both verified structural performance and outdoor durability in a mid-span section, this is a common specification for pergola beams and deck bearers. Note that H3 is rated for above-ground use only — for in-ground posts, an H4 or H5 rated product is required.
