When it comes to manufacturing laying hen cages for export, choosing the right material is crucial. Q235 steel stands out as an excellent choice due to its remarkable mechanical strength, economic efficiency, and suitability for the specific requirements of the poultry - farming scenario.
Mechanically, Q235 steel has a yield strength of approximately 235 MPa, which provides sufficient structural integrity for the cages. This strength ensures that the cages can withstand the daily activities of the hens, such as pecking, scratching, and moving around, without deforming easily. Moreover, its good ductility allows for easy processing, enabling the production of various cage designs.
Economically, Q235 steel is cost - effective. Compared to some high - end alloy steels, it offers a reasonable balance between price and performance. This cost - efficiency is particularly important for export - oriented businesses, as it helps to keep the production cost down while maintaining a high - quality product, thus increasing the competitiveness in the international market.
Hot - dip galvanizing is a process where the steel is immersed in a bath of molten zinc at a temperature of around 450°C. The zinc reacts with the steel surface to form a series of zinc - iron alloy layers, which provide a physical barrier against corrosion. On the other hand, aluminum - zinc alloy coating involves applying a layer of an alloy composed of aluminum and zinc to the steel surface. This alloy coating combines the corrosion - resistant properties of both aluminum and zinc.
Let's look at some data to compare their rust - prevention efficiency. In a simulated coastal environment with high humidity and salt content, the corrosion rate of hot - dip galvanized cages is about 0.05 mm/year, while that of aluminum - zinc alloy - coated cages is approximately 0.03 mm/year. This shows that the aluminum - zinc alloy coating has a better anti - corrosion performance in such harsh conditions.
| Coating Type | Corrosion Rate (mm/year) | Expected Service Life (years) |
|---|---|---|
| Hot - Dip Galvanizing | 0.05 | 15 - 20 |
| Aluminum - Zinc Alloy Coating | 0.03 | 20 - 25 |
Let's take a look at some real - world examples. In a tropical region with high humidity and high temperature, a poultry farm using hot - dip galvanized cages reported some signs of rust after 8 years of use. In contrast, a farm in a similar climate using aluminum - zinc alloy - coated cages had no visible rust even after 12 years. In a cold and dry region, both types of coatings performed well, but the aluminum - zinc alloy - coated cages still showed a slightly longer service life.
International standards such as ISO9001, ISO14001, and CE play a vital role in validating the quality and compliance of laying hen cages. ISO9001 certification ensures that the manufacturing process follows a strict quality management system, which guarantees consistent product quality. ISO14001 certification indicates that the production process is environmentally friendly, which is an important factor for many international buyers. CE certification is a mandatory requirement for products sold in the European market, which shows that the cages meet the relevant safety, health, and environmental protection requirements.
The structural design of laying hen cages, such as the H - type layout and reasonable thickness selection, has a significant impact on the overall stability and space utilization. The H - type layout provides a more stable structure, which can better withstand external forces. Moreover, it allows for a more efficient use of space, enabling more hens to be housed in the same area. Choosing the right thickness of the steel bars can also enhance the durability of the cages without adding excessive weight.
