Lets compare against aluminium coops and tractors

Galvanized welded steel is significantly stronger than aluminum, especially when combined with welding. The welded construction provides a more rigid and durable structure, which can withstand the weight and activity of chickens, as well as external stress like wind, rain, or predators trying to break in. Aluminum, when held together with plastic connectors, can be much less stable and prone to wobbling, especially over time as plastic connectors wear out or degrade.

Galvanized steel, with its protective zinc coating, is highly resistant to rust and corrosion, making it durable in all weather conditions. In contrast, plastic connectors may degrade under UV exposure or extreme temperatures, leading to parts coming apart, weakening the structure. Over time, plastic components can become brittle, break, or lose their grip, compromising the integrity of the entire coop or tractor.

Galvanized steel is designed to last for decades, even in harsh outdoor environments, while aluminum with plastic connectors may wear out more quickly. Plastic components are particularly vulnerable to the sun's UV rays, which can cause them to degrade, making the coop less effective over time. The overall lifespan of a steel structure is generally much longer than an aluminum one with plastic connectors.

The welded steel design offers better security against predators like cat, dogs, foxes, or even larger birds of prey. Plastic connectors holding an aluminum frame together are far more likely to be pried apart by determined animals. Steel, on the other hand, is far more resistant to tampering or forceful entry, ensuring better protection for your chickens.

Galvanized steel requires less maintenance compared to aluminum coops assembled with plastic connectors. The plastic connectors may need to be replaced or tightened periodically, and they can be prone to breaking or becoming loose, which could compromise the structural integrity of the coop. Galvanized steel, once set up, requires very little upkeep, as the metal's coating protects it from rust and deterioration.Galvanized steel requires less maintenance compared to aluminum coops assembled with plastic connectors.

Steel's resistance to various weather conditions, including rain, wind, and snow, is far superior to that of aluminum held together with plastic connectors. While aluminum itself is weather-resistant, the plastic connectors are vulnerable to degradation from sun exposure, freezing, or excessive moisture, which can lead to failure in maintaining the coop's structural integrity.

Galvanized steel is much more durable than wood, particularly when exposed to the elements. Steel is resistant to rot, warping, and insect damage (like termites or ants), which are common issues with wooden coops. A wooden coop may require more frequent repairs and replacements due to wear and tear, whil galvanized steel can last much longer without degrading.

A galvanized steel chicken coop requires minimal maintenance compared to a wooden one. Wood needs to be treated or painted regularly to prevent rot and protect against moisture, and it may also need sealing to protect against pests. Steel, with its galvanized coating, is rust-resistant and does not require the same level of upkeep.

Steel is far more secure than wood in protecting your chickens from predators. While wood can be chewed or broken through by larger animals like raccoons or foxes, steel is much harder to penetrate. Additionally, steel doesn’t splinter, which can create weak spots in wooden coops that predators could exploit.

Steel is inherently fire-resistant, while wood is highly flammable. In the event of a fire (whether accidental or from external sources), a steel coop will offer more protection for your chickens and significantly reduce the risk of destruction.

Steel, particularly galvanized steel, is highly resistant to the effects of harsh weather, such as rain, snow, and humidity. Wood can swell, warp, or crack under prolonged exposure to moisture, leading to structural damage or deterioration. Steel is not affected by moisture in the same way and will maintain its integrity over time, even in wet or snowy conditions.

Wooden coops are susceptible to pest infestations, including termites, rodents, and other insects that can damage the structure. Steel does not attract these pests and will not be damaged by them, providing a healthier and more secure environment for your chickens.

Galvanized welded steel is stronger and more secure than wood, providing better protection for your chickens. A welded steel coop is less likely to collapse or be broken into, ensuring your chickens are safe from both environmental factors and predators.

While galvanized steel may have a higher upfront cost than wood, its durability and low maintenance needs make it a more cost-effective option in the long run. Wooden coops may need frequent repairs or replacements, especially if the wood starts to degrade, whereas a galvanized steel coop can last many years without additional expenses.
