There are unified industry standards for disaster relief tents, and there are standards for the materials used and how they are made. As long as a legitimate manufacturer agrees to produce according to the standards, you can purchase them with confidence.
Taking 12 single tents as an example, the entire set of tents is divided into two packages: a tent bag and a pole bag (one package for aluminum alloy pole pieces), with a production manual certificate placed inside. The manufacturer will place it according to the standard.
The two sides of the disaster relief tent were previously printed with disaster relief tents, while the new standard printed with emergency relief, and the words' disaster relief 'were printed on both sides of the door. The information of the production unit and the supervising unit is printed under the window.
