The ability of the patio lounge set to withstand collisions and compression is indeed closely related to its material. Chairs made of different materials will behave differently when facing impact or compression. The following are the effects of different materials on the collision and compression resistance of patio lounges:
1. Aluminum alloy material
Collision resistance: Aluminum alloy chairs perform well in withstanding general impacts due to their lightweight and sturdy characteristics. Aluminum alloy has strong corrosion resistance and can withstand certain impact forces. If subjected to severe impact, the aluminum alloy frame may bend or undergo slight deformation. Aluminum alloy will not suffer serious damage when subjected to daily mild collisions, but may be affected in higher intensity collisions.
Squeezing resistance: Aluminum alloy material is relatively soft and may deform under long-term pressure, but compared to other lightweight materials, its ability to resist compression is still good. Aluminum alloy chairs have strong compressive strength if they are not subjected to excessive compression.
2. Wood
Collision resistance: As a natural material, the collision resistance of wood depends on the type and processing technology of the wood. High quality wood (such as teak, oak, etc.) has strong toughness and hardness, and can withstand light impacts. Wood is sensitive to larger or uneven impacts, and is prone to cracking or breaking, especially at the joints of the wood. The collision resistance of wood is relatively low, especially for wooden chairs exposed to outdoor environments, which increase the risk of cracking due to moisture and climate change.Squeezing resistance: Wood is relatively strong, but if it is subjected to continuous compression for a long time (such as heavy objects being pressed on a chair for a long time), the wood may deform. The elasticity of wood itself is poor, and continuous pressure may cause the wood to bend or crack.
3. Plastic or resin
Collision resistance: patio lounges made of high-density polyethylene (HDPE) and other resin materials typically have strong impact resistance. Plastic and resin chairs are relatively lightweight, but they have good impact resistance and can withstand mild collisions in daily use. This type of material may become brittle in cold weather, making it prone to breakage or cracking upon collision. The collision resistance of resin and plastic is moderate, but they cannot withstand excessively severe impacts.
Squeezing resistance: Plastics and resins typically have strong resistance to compression, especially high-density polyethylene (HDPE) materials. They can withstand general pressure and loads, but may deform or soften under extreme loads. Resin materials may experience reduced compressibility and deformation at extremely high or low temperatures.
4. Steel
Collision resistance: Steel is a very sturdy material with extremely high impact resistance. Steel patio lounges can withstand a large degree of collision and impact, and even in the event of a strong collision, it is difficult to deform or break. The collision resistance of steel is very strong, especially in the event of an impact. Steel chairs can effectively disperse the impact force and avoid local damage.
Squeezing resistance: Steel exhibits extremely strong compressive strength when subjected to compression. Even under significant pressure or weight, steel usually does not deform. However, if there is no good protective layer on the surface of the steel and it is exposed to a humid environment for a long time, it may rust, which in turn affects its strength and stability.
5. Synthetic fibers and fabrics
Collision resistance: Synthetic fiber materials (such as polyester, acrylic, etc.) and outdoor fabrics generally do not have strong collision resistance, especially under high-intensity impact, they are easily torn or damaged. The fabric part of most patio lounges is mainly used as a comfortable cushion layer, rather than withstanding strong collisions and compressions. If high-density synthetic fibers are used as the surface material of the seat, its impact resistance will be improved, but its impact resistance is weaker compared to metal and wood.
Squeezing resistance: Synthetic fiber materials have poor compression resistance, especially under long-term heavy pressure, which may cause the fabric to sink or break. Even if the surface fabric has good weather resistance, it may still experience indentation or collapse under long-term pressure.
