Rain and wind resistance of outdoor tents

Outdoor camping and mountaineering tents use light and thin polyester and nylon fabrics, which will be light to carry, and the density of the fabrics in the warp and weft directions is relatively high. The tent should be made of cotton-type nylon silk with good air permeability. From the perspective of use, the performance of nylon silk is better than cotton. PU-coated Oxford cloth as the base material greatly exceeds PE in terms of robustness, cold resistance, and water resistance.

Waterproof 300MM is generally used for beach tents/shading tents or cotton tents for drought and less rain. Waterproof 800MM-1200MM is used for conventional simple camping tents.

Waterproof 1500MM-2000MM is used for relatively mid-range tents, which need to travel for many days.

Waterproof tents above 3000MM are generally professional tents that have been treated with high temperature/cold resistance techniques.

Bottom material: Generally, PE is the most common, and the quality depends mainly on its thickness and warp and weft density. It is better to use Oxford fabrics for higher grades, and the waterproof treatment should be at least 1500MM or more.

The inner fabric is generally breathable nylon or breathable cotton. The quality mainly depends on its density.

The rainproof performance of the outer tent cloth, this index is still calculated according to the number of mm of water column per square centimeter.

Generally, the rainproof tents are above 1500mm water column, which can prevent moderate to heavy rain; individual tents reach 3000-4000mm, which can prevent continuous heavy rain. The high-quality rainproof tarpaulin not only has a high rainproof index, but also has a thick rubber strip at the joint of the awning line to prevent water seepage at the seam.

It is necessary to consider whether it can withstand conditions such as strong wind and heavy rain. The first is the coating, generally choose PU800 coating, so that the coating does not leak under the static water column of 800mm, can prevent light to moderate rain; PU1000-1200 coating can prevent moderate to heavy rain, more than 1500mm basically Can be used in various environments. The number of aluminum poles should also be considered. A tent with 2 sets of ordinary aluminum poles can withstand strong winds of about 7-8, and the wind resistance of 3 sets of aluminum poles is about 9; tents with 3-4 sets of 7075 aluminum poles can be at 11 Used in blizzard environments around. At the same time, we must also consider the tent floor cloth, generally choose 420D wear-resistant Oxford cloth.
