This historical evolution underscores why choosing galvanized screws is not just a trend but a wise decision based on decades of experience.

Что такое оцинкованные винты? Технические детали

Оцинкованные винты – это крепежные элементы, изготовленные из стали и покрытые цинковым слоем через процесс горячего цинкования или электролитического осаждения. Горячее цинкование involves dipping the screw in molten zinc, resulting in a thick, durable coating that provides excellent protection. Electrogalvanizing uses an electric current to deposit a thinner layer, which is still effective but may be less robust in extreme conditions.

Ключевые характеристики оцинкованных винтов включают:

• Материал: Обычно из углеродистой стали, которая прочна и economical.
• Покрытие: Цинковое покрытие толщиной от 5 to 100 micrometers, depending on the process. Hot-dip galvanizing typically offers 50-100 µm, while electrogalvanizing provides 5-25 µm.
• Коррозионная стойкость: Цинк действует как барьер и sacrificial anode, protecting the underlying steel. This can extend the life of the screw by decades, especially in humid or salty environments.
• Прочность: Steel core provides high tensile strength, making them suitable for heavy-duty applications.
• Разновидности: Available in various types such as wood screws, machine screws, self-tapping screws, and more, each designed for specific materials like wood, metal, or drywall.

Процесс производства начинается с формовки стальной заготовки, followed by cleaning and then galvanizing. Quality control ensures even coating and adherence to standards like ISO 1461 for hot-dip galvanizing. This technical foundation makes galvanized screws a superior choice compared to uncoated or alternatives like stainless steel, which we will compare later.

Преимущества оцинкованных винтов

Выбор оцинкованных винтов offers numerous benefits that justify their popularity in construction and repair. Let's delve into the key advantages.
