This report summarizes the quality inspection results of anti-corrosion wood used in the outdoor landscape project of a residential community. The anti-corrosion wood is made of Pinus sylvestris, which has been treated with the pressure impregnation method using copper azole (CA) preservative—complying with the national standard GB/T 22102-2020《Anti-corrosion Wood》. A total of 80 pieces of anti-corrosion wood were randomly sampled for inspection, covering common specifications such as 40mm×90mm and 50mm×150mm.
The inspection focused on two key aspects: preservative penetration and corrosion resistance. The preservative penetration test showed that the preservative had penetrated evenly into the wood, with a penetration depth of more than 8mm in the cross-section—meeting the minimum requirement of 6mm for outdoor anti-corrosion wood. In the accelerated corrosion resistance test (simulating 5 years of outdoor environment), the sampled wood showed no signs of mold growth, insect infestation, or wood fiber degradation, and its compressive strength remained at more than 90% of the original value. Additionally, the surface of the anti-corrosion wood was smooth without cracks or obvious color differences, and the formaldehyde emission was detected to be less than 0.124mg/m³, conforming to the environmental protection standard.
In conclusion, all inspected indicators of this batch of anti-corrosion wood meet the quality requirements for outdoor landscape use. It has good corrosion resistance and environmental performance, and is qualified for on-site installation in the project.
