We export tens of millions of dollars of windows and doors to the U.S. every year, and we know that improper packaging can cause breakage of the product when it arrives on site, and the biggest loss from this is, I'm afraid, the cost of time, after all, workers on site have requirements of working time and it needs to wait for a new shipment to arrive in case of damage occurs to the goods. So, we pack each window individually and in four layers, and finally into wooden boxes with non-fumigation, and at the same time, there will be a lot of shockproof measures in the container, to protect your products. We are very experienced in how to pack and protect our products to ensure they arrive at the sites in good condition after long-distance transportation. What the client concerns, we concern most.
