The struts are strong and resilient: the best rods at the moment are carbon rods, followed by aluminum alloys, then fiberglass, and finally irons (except for troops, which are pretty much useless). Aluminum alloy rods are divided into aviation aluminum alloys, 7075T9 and 7001T6 in terms of price and performance. A reasonable combination of strut sizes is obtained: 4 rods of 50mm, 3 rods of 40mm, and 2 rods of 20mm; the most reasonable design size of the socket is given: the outer diameter is 8.5mm, the wall thickness is 0.75mm, and the rod core extends 40mm, wall thickness 1.0mm. The wind resistance of tents is not only related to the texture diameter of the tent poles, but also to the number of sets of tent poles. Generally speaking, the more sets of tent poles, the better the wind resistance performance. For example, tents with 2 sets of ordinary aluminum poles can withstand strong winds of about 7 to 8, and the wind resistance of 3 sets of aluminum poles is about 9. Tents with 3 to 4 sets of 7075 aluminum poles can be used in blizzard environments of about 11.
The bottom of the account should be waterproof and wear-resistant: the bottom of the account should be waterproof and strong and wear-resistant. The commonly used materials for the bottom of the account are PE cloth and waterproof polyester cloth. PE tent bottoms are used for middle and low-grade tents, and waterproof polyester fabrics are used for middle and high-grade tents. PE is a polyethylene material, similar to a low-grade snakeskin bag. The tent actually uses a PE material with a waterproof membrane on both sides. A large number of export tents use this material. The bottom of the tent is in contact with the ground and is easily scratched by debris, grass roots, branches and other debris. Therefore, before camping outdoors, clean up hard objects on the ground, or use tent cloth to cover the ground as a protective layer. Tent floor cloth generally uses 420D wear-resistant Oxford cloth. In addition, choosing a tent with front and rear double doors or facing windows is more conducive to ventilation; considering the space required for items, it is recommended to choose a double tent; the design should be reasonable, and there should be enough ground and windproof rope; the packaging bag should be strong and durable, The number of tent nails should be sufficient, the strength of the aluminum nails should be large, and the tent rope should be used to fix the tent.
